Drevitalize 3.24

DREVITALIZE DOCUMENTATION



MAIN SCREEN

DRevitalize is a program that repairs bad sectors (physical defects) on popular magnetic media (hard drives and also floppy drives to some extent) by generating a special sequence of high and low level signals around the physically damaged area. The surface of almost any drive can be repaired with this utility (even hard drives that were dropped down or exposed to electromagnetic fields). However, in some cases DRevitalize software will simply force reallocation of bad sectors instead of repairing them. Whether sectors are restored or reallocated is totally dependent on the drive surface and current drive setup which usually forces intelligent defect management by default.

On the main screen there is a possibility to change the mode of operation and the system of operation. Mode can be either single or multi sector for fast area scans. Multi sector mode should be the default scan mode in most cases. Single sector mode is designed to be used only for seriously damaged hard drives to precisely test a small area. System can be either WinAPI, ATA/SCSI or ATA/SCSI RV (Read Verify). Direct access modes like ATA/SCSI and ATA/SCSI RV are more precise and faster. This is especially true when a SATA drive is connected via USB bridge. In this case it is recommended to set the system of operation to SCSI RV to scan drives a lot faster, provided that the SCSI bridge translates SCSI RV (Read Verify) command.

Drives with a file system mounted on them need to be locked first. If DRevitalize can't do it, those drives can still be tested in 'READ ONLY' mode. Main system hard drive running the operating system can no longer be repaired under Windows Vista or higher. The DOS version should be used to do it if necessary.

OPTIONS SCREEN

The options screen allows to select 1 of the 7 available functions. The scan only mode, scan and repair mode (read test), scan and repair mode (write test), analyze SMART data, copy raw data to a destination drive, features menu and device configuration overlay menu.

READ TESTS

There are 2 possible functions that execute read tests. The first one will only scan the selected drive area informing about slow and bad sectors. This is the scan only function. The second one will try to repair bad sectors found on read access and refresh slow sectors if it was instructed to do so. Refresh slow sectors must be explicitly specified by typing yes in the additional options menu. The default refresh slow sectors value is 150ms for multi sector and 20ms for single sector scan mode but the user can alter this value. This is the delay above which a slow sector will be treated as a bad sector and revitalized. This is a very dangerous operation however and should be applied with caution and only if really necessary. Sudden power loss might result in severe data corruption on the revitalized drive. Further function specific options include the number of passes and repair count loop. Number of passes is the amount of times the selected area will be scanned. Repair count loop value specifies the amount times the internal drive repair procedure is executed on a bad or slow sector.

scan only scan and repair




WRITE TEST

The write test will try to find bad sectors by executing sequential zero fill commands. If such bad sector, called bad sector on write, is discovered a modified revitalize procedure will be applied. This modified procedure does not include any read commands. This is pure drive surface shaping via writing. Like in the read tests, here it is also possible to refresh slow sectors on write. This works the same way except that only the simplified revitalize procedure including write commands is executed.

write test



COPY RAW DATA

This is a completely new function introduced in v3.xx of Drevitalize used to copy sector by sector one drive to another with the possibility to provide arbitrary source and target offsets as well as the desired amount of sectors to copy. Both progress bars from source and destination are shown on the screen at the same time. Please note that only the source progress bar is updated with possible error codes (S - slow, B - bad, C – corrected). Statistics with access time are updated on the fly like on the scan screen. An important fact to note is the read errors value from the source drive which does not only show the amount of bad sectors on the source drive. If a second value is displayed in parenthesis next to the read errors value it means that the Drevitalize internal error correction mechanism was able to correct the read error on the fly and retrieve all information from the bad sector. In other words if the read error value is equal to the value displayed in parenthesis it means that despite bad blocks on source drive all data from the requested region was copied to the destination drive.

SMART DATA

This is a pure informatory and statistics function which provides a detailed overview of the drive health. All good attributes are signaled with a green OK confirmation on the right side of the screen. Anything that is still good but suspicious and will probably soon need further attention is displayed in white. All bad attributes are displayed in red. SMART WData is the default 16-bit word data shown in earlier versions of Drevitalize and SMART XData is the extended 4 bytes from the raw value field. Starting from version 3.24, Drevitalize will analyze the overall status of the drive and display the result either as : perfect drive (green), drive has warnings (white) or damaged drive (red).

SMART data



FEATURES MENU

The features and firmware data menu currently defines 16 possible drive parameters and functions that can be modified or executed. Read and write cache, the host protected area menu, the secure erase drive function, the format unit function, the acoustic management menu, the SMART specific functions which control how the SMART feature set works, the ATA security functions and the clear defect reassign function. Drives on ATA/SATA channel will in most cases have security state set to frozen. Please note the difference on the screen shots below. This is the same drive that was connected via eSATA interface on the first screen shot and USB interface on the second screen shot. The only way to exit security frozen mode is to disable security features via DCO menu, disconnect the eSATA drive (or switch off the PC in case of ATA/SATA drive), run DRevitalize again and select DCO restore.

SECURE ERASE

The Secure Erase ATA feature set is a powerful and very dangerous ATA command. I would advise to do a secure erase using master password becasue the master password does not lock the drive if the procedure is suddenly stopped due to lack of power or some other unexpected reason. Therefore before starting this procedure please enter a master password with ATA security function : ATA Master Password.

Once the master password is set it needs to be reentered on secure erase dialog screen. This is because the procedure can also be used to unlock ATA drives with unknown user password but known master password. Some manufacturers have predefined master passwords that will work with secure erase if master password was not modified before.

If you decide to run secure erase with user password. A temporary user password with high security level will be set. This password is 'ABCDEF'. In case the procedure fails DRevitalize will try to automatically remove this password. However in case of loss of power it is impossible. The user will have to remove this password manually on next power up.

Please note that laptops/notebooks use a different ATA password system than the clean one used in DRevitalize. It is not possible to start a laptop with a drive on which the password was set by DRevitalize. If the user wants a password protected hard drive, he/she needs to set the ATA drive password either in the BIOS or in the specific laptop manufacturer utility. If the laptop is unable to start because of a failed ATA secure erase procedure, the only way to unlock the drive is to remove the drive from the laptop and connect it to a desktop PC or another laptop via USB and run DRevitalize specifying the required security options. Please note that only the Windows version is able to work with drives connected via USB.

FORMAT UNIT

This vendor specific Format Unit ATA command clears the defect reassign information (Grown Defect List) and initializes all user data sectors by executing a full format with Primary Defect List. This procedure follows the same ATA security requirements as secure erase with the exception that it does not need a password to execute. However, the command can not be started in security frozen mode, security disabled via DCO mode or when security feature set is not implemented. Currently only IBM (old), Hitachi (old), HGST (Hitachi new), Western Digital (new) and Fujitsu (ATA only) hard drives are supported.

format unit 1 format unit 2




ATA SECURITY

This sub menu introduces 4 new commands related to the powerful ATA security feature set. ATA Lock drive, ATA Unlock drive, ATA Master Password and ATA Security state. The first command locks the drive with user password, either in high security mode or maximum security mode. The difference between the two modes is that maximum security mode does not allow a drive to be unlocked with master password. In this case only secure erase can be started with master password. The second command unlocks a drive which is in security locked state. Either user or master password can be specified. However master password will only work if user password level is set to high. This command needs to be executed before trying to disable the password if drive is locked. The third command will set a master password on the drive with default master password revision code of 0xFFFE.

The ATA security state command displays the current security information about the drive. If the drive is unlocked and a password has been set on it, the system will ask if the user wants to disable the password. Alternatively, the user has the option to enter security frozen mode if no password is set and security is open.

DEVICE CONFIGURATION OVERLAY

The Device Configuration Overlay feature set allows to reduce the capabilities of the selected drive by modifying some of the optional commands, modes, and feature sets that a device reports as supported in the IDENTIFY DEVICE or IDENTIFY PACKET DEVICE data as well as the capacity reported. Selecting a specific feature will flag the action performed on it as either disable or enable depending on it's current condition. After the required values are selected the user needs to run DCO modify function for the changes to take effect. DCO modify can not be run 2 times in a row. Each DCO modify must be followed by a DCO restore to bring the drive back to it's original state. Finally, executing DCO freeze will block the drive DCO functions.

device configuration overlay



THE SCAN SCREEN

This is the main screen that is displayed during scan. The top left of the screen shows drive hardware information. The interface, hardware buffer size, bytes per sector native and emulated (e = emulated, n = native), firmware and serial number. The top right of the screen shows the current protocol used, software buffer used by DRevitalize, access system and MULTI SECTOR mode counters. The access system can be either WinAPI, ATA/SCSI or ATA RV/SCSI RV in DRevitalize for Windows. The DOS version can use AHCI, AHCI Read Verify, BIOS via INT13H extensions or direct port access if ATA PIO or ATA RV is selected. The MULTI SECTOR counters SLOW and ERROR show how many times a slow or bad area with error was detected during scan.

The default limit value for SLOW counter can be altered with a user defined number for access time when revitalizing slow sectors. When the user specifies 100ms for multi sector scan mode with revitalize slow sectors active, any area with access above 100ms will be counted as slow area. The ERROR counter below the SLOW counter shows how many times the system entered RED SINGLE sector read mode during scan. This mode means that there was an error in multi sector scan and that the program needs to check each sector of that area separately.

Bottom left corner of scan screen shows access time statistics on the fly with FAST, SLOW and CUR access times in ms for the current block of sectors. M specifies the current mode (SINGLE or MULTI), R specifies the current repair count 1 - 99, S specifies the slow sectors refresh access time and whether it is activated or no, P specifies the current pass and total passes. The last value is the scan progress in %.

  • Drevitalize (all) : log file is now more detailed. It displays bad sectors found, refreshed sectors, bad SBuff areas and slow Sbuff areas. Sbuff : Software Buffer reads/writes in multi sector mode. By default, anything with an access higher than 150ms per Sbuff area is treated as a slow area. For a drive exposing 512 bytes per sector access, Sbuff is 32KB under DOS and 128KB under Windows.
  • Starting the DRevitalize 3.22+ (registered) installer will auto update any previous 3.xx DRevitalize versions installed. Any old 3.xx demo or registered versions of Drevitalize will be removed.
  • Drevitalize (Windows) registered will now by default check if new version is available when starting. User can stop checking for updates only when local version of Drevitalize is not up to date. No serial numbers or internet IPs are collected.
  • Double signed with SHA1 and SHA256 key to support all Windows versions starting with Windows Vista.

Advantages of new Drevitalize 3.21 Windows/DOS

  • DRevitalize (Windows) no longer uses CPU when idle.
  • Corrected some spelling erros.
  • Log file is always saved to desktop after a hard drive scan.
  • Drevitalize (DOS) write cache disable on write command timeout during scan fixed.

  • Copy Drive function now supports the optional ATA command write uncorrectable to target drive.
  • Read/Write long procedures, although implemented, are currently disabled and not used by any function in this version of Drevitalize.

Advantages of new Drevitalize 3.20 Windows/DOS

  • DRevitalize (Windows) has a different source handle creation strategy making the process run on almost any type of system.
  • It is now possible to copy a drive into self in the Windows version.
  • Further improved compatibility with a wide range of USB bridges – proper implementation of ATA passthrough 16.
  • Introduction of several functions into features menu : secure erase, format unit, automatic acoustic management, reverting, ECC control feature.
  • SMART specific functions : attribute autosave, automatic off-line collection, save attribute values on demand.
  • ATA security feature set : ATA lock drive, ATA unlock drive, ATA set master password, ATA display security state.
  • Device Configuration Overlay menu with the possibility to set any supported drive configuration.

Advantages of new Drevitalize 3.13 Windows/DOS

  • DRevitalize (Windows) copy raw data function now properly locks and dismounts any volumes present on the target drive before starting the copy.
  • Improved compatibility with a wide range of USB bridges – proper implementation of ATA passthrough strictly according to SAT docs.
  • DOS version - cache switching mechanism now affects both, read and write cache when in bad sector recovery loop.
  • Advanced features and firmware menu started. Currently only a small set of advanced features is implemented.
  • Host Protected Area volatile and non-volatile option added to advanced features menu. Non-volatile modification is preserved on power off.
  • Modification of SMART data colors. Good attributes are displayed in gray with a green OK. Important attributes that need attention but are still OK are displayed in white, failed attributes are displayed in light red.

Advantages of new Drevitalize 3.12 Windows/DOS

  • Slow sectors value now resets to 150ms or 20ms (single mode) for next scan if default value was changed.
  • Windows 'copy raw data' function now has a confirmation box whether to proceed or not - user has to type 'YES'.
  • DOS version - slow sectors refresh does not disable read look-ahead in single sector mode. A slow sector is not a bad sector that is why additional ATA commands do not need to be applied. This makes the refresh process as fast as under Windows or Drevitalize 2.44 DOS.
  • DOS version - single sector mode runs at full possible speed. Additional ATA commands are only executed when entering bad sector recovery loop and for the next remaining sectors on the current block - DOS block has 64 sectors (SBuff is 32KB on a 512 bytes per sector disk).

Advantages of new Drevitalize 3.11 Windows/DOS

  • Windows GUI instead of console mode for the Windows version.
  • Asynchronous I/O for WinAPI access, synchronous for ATA/SCSI (DRevitalize 2.42 uses synchronous I/O for all modes).
  • Faster reads/writes/scan x2 or x3 due to intelligent GUI update, not every I/O operation like in 2.42 version.
  • Extended and precise status and error information with WinAPI lasterror code, SCSI sense or ATA registers displayed when scanning drive. Progress in % shown on bottom of screen.
  • SMART status with extended info and updated attribute names (extended info includes the missing bytes from raw value).
  • Fast copy option with recovery mode. Possibility to copy 1 drive to another with selected offsets and number of sectors - intelligent 3 step recovery of encountered bad blocks on source drive (achieved with reads only – no data or signals are written to the source drive).
  • Minor bugs and enhancements like serial number of HDD in Windows 7/8 corrected. Aware of Windows 10 - target it Windows 10 if detected.
  • ATA/SCSI system now uses DMA or DMA EXT access instead of PIO access for drive reads and writes in multisector mode.
  • DOS native AHCI on most SATA controllers compliant with the AHCI v1.3 specification. Full error diagnostics and failure recovery of the HBA according to the AHCI specification v1.3.
  • Possibility to detect up to 32 AHCI SATA devices under DOS. To run the DOS version without AHCI support please use the -noahci switch on command line.
  • Corrected multi sector and single sector precision timers, corrected and improved ETA countdown.
  • Able to detect 512e (512 bytes per sector emulated) and 4096n (4096 bytes per sector native) drives.
  • DOS version has a modified recovery procedure which is significantly more effective than the windows version and any other DRevitalize versions released in the past. Moreover, in SINGLE scan mode or upon entering SINGLE recovery mode read look-ahead cache will be disabled to provide environment as close as possible to floppy recovery mode without any caches going in the way. This change further enforces proper recovery, minimizing false success and the relocation of sectors to spare area.
  • Consistent write cache flush procedure ported to AHCI (available since 2.42 version in ATA and ATA/RV modes).
  • Higher precision key handler under DOS to catch quit requests.
  • Advanced data recovery on-the-fly from bad sectors. At the end statistics screen DRevitalize will show the number of bytes reclaimed from bad sectors. Bytes that were unreadable before by normal means. This feature is only available in read and repair mode. Please be aware that any bytes residing in bad sectors that could not be recovered after the 4 step retry recovery process in multi sector mode (or 3 step retry recovery process in single sector mode) will be cleared out in order to reclaim the bad sector. This is a normal behaviour of any Drevitalize version since release 1.00.
  • Possibility to copy with recovery from any logical sector drive to any logical sector drive between 512 and 8192 bytes per logical sector. Logical sector size of both drives needs to be a multiple of 512. Current limitation is 4096 bytes per logical sector for DOS version and 8192 bytes per logical sector for Windows version. Copied sectors value will always reflect the target drive sector size.
  • Windows 7 special case : Bytes per logical and bytes per physical sector are taken directly from ATA identify if possible. It appears Windows 7 returns wrong values for physical sector size of advanced format SATA drives connected directly to SATA controller. Problem does not occur on higher Windows versions.
  • ATA DMA transfers are now cut to 64KB chunks to ensure maximum compatibility to any driver and Windows OS starting from Windows XP.
  • DRevitalize (Windows) will request 32MB physical memory from the operating system. It will refuse to run if the system is not able to provide that much. All possible transfer buffers will be locked into physical memory.

Advantages of new Drevitalize 2.44 DOS update

  • New option allowing to revitalize slow sectors. The user will be able to specify a delay in ms when accessing a single sector above which the sector will be treated like a bad sector. Sector content will be refreshed after applying the drevitalize process.
  • New option allowing to revitalize slow sectors. The user will be able to specify a delay in ms when accessing an area of sectors above which the area will be treated like a bad area. Each sector of that area will be refreshed after applying the drevitalize process.
  • Special console handlers to restore the repaired disk state. They take over on closing the Drevitalize window.
  • Extended info with 3 color steps for progress bar with mode, repair count, slow sector refresh and number of passes information.
