Initial Data Recovery Diagnostic

Step 1:  Drive connected to three different SCSI controllers.  Two controllers do not recognize at all, one (Adaptec 39320A) shows drive but with 0 byte size and returns error of imminent failure.  Drive assumed to have translator issue.

Step 2:  Boot to DOS and attempt to run plscsi.exe to send custom SCSI commands (Had to order compatible SCSI card with DOS driver. Adaptec AIC-7890 AB card)

Step 3: Boot to DOS, load Adaptec SCSI card driver and run plscsi.exe.  Input command: “plscsi -w” (drive identified in list of connected devices)

Quote Customer: $750 for repair / recovery. (Approved 5/23/2014)

Data Recovery Update 5/27/2014

Step 1: Boot back into DOS, load drivers, run plscsi.exe

Step 2:  Manually input SCSI Commands to Regenerate translator.

Step 3:  Allow drive to sit for ~5min to complete translator regeneration

Step 4: Power cycle drive (does not beep this time)

Step 6: Boot system to Linux, verify that device is visible and shows correct size (successful)

Step 7: Image drive to another using ddrescue (data recovered with only 53Kb of unread data in ten areas of bad sectors)

Recovery 99.99% success.
