First SATA drives are detected. Then a fast DMA read command is executed repeatedly on the first detected drive from sector 0 till the end. The source code compiles under a recent version of WATCOM C++ (1.9 or higher).

So here it is. First SATA drives are detected. Then a SMART status is run on the first detected drive. The source code compiles under a recent version of WATCOM C++ (1.9 or higher).

Dziękuję Ci!

i think the problem really is usb adapter. i tried different usb adapter and with it i could not even enter features section while with other one i can.

USB enclosure must support the SATL SCSI to ATA translation. So basically you need to have a USB to SATA adaptor with UASP support so that you can send ATA passthrough command via SCSI passthrough format. That's how it's done in DRevitalize (Windows).

direct sata also does not work.
i booted from flash drive. from there i was able to enter dco section. i tried to disable "security mode commands" but when i press "dco set" i get: "dco result: error".
then i had one idea, do not know if it was right or stupid one, i successfully set hdd password from bios. but when i tried to enter "features" menu i got error: "ata command error! this drive does not support ata commands."
well, i give up at this point. i will try to get another sata-usb adapter.

Concerning SATA, the thing is that direct SATA connection will probably result in a freeze lock of the drive when starting, making it impossible to send any password related commands. This usually happens in laptops and some desktop PCs. Disabling security commands via DCO might help. I see that it did not work. Well, please also try DCO restore. Maybe someone messed up with DCO before and it needs to be reset.

If it's possible to enter DCO menu under DRevitalize DOS/UEFI it should also be possible to disable security commands.

very strange, write cache is enabled now.

about password, it opens window, i enter password, press set and after 2 seconds it gives error

i have 4 different hgst/hitachi drives. my goal was to "format unit" them. one formatted successfully without any problems or passwords. other three have this identical problem.

I just tested a HGST HTS545050A7E680 (500GB) drive via USB and it behaves correctly. That is I can set user password without problems and "format unit" will only start if user password is set.

There may be problems when USB bridge does not fully support sending ATA commands via SCSI. Please make sure the connecting USB cable and bridge is a modern USB 3.0 compliant device designed to attach the newest SATA drives. Otherwise there is nothing more I can sugget but to attach the drive via direct SATA or eSATA.
