Re: ReadFile \ Write File [Failed LBA ???]

Most IDE devices implement a minimal part of the SCSI command set. As an
example, there is no support for REASSIGN BLOCKS command. The whole GDL
concept is completely obfuscated by IDE disk devices. If you ever get an
IDE drive that generates a bad-block error it means that the device has
completely exhausted it’s sector spare pool, and really should be discarded
to the bit-bucket in the sky.

Yes, you can use SCSI pass-thru for ATA/ATAPI devices too. Class driver
will translate SCSI command set to ATA/ATAPI command set.
