OT : SCSI drive question

[Emmerich]

On my PC I had a SATA drive as C: and a SCSI as E:. I have added a second SATA drive. My PC sees the SATA drives but not the SCSI anymore. I have removed the second SATA to go back to original and it still won't see the SCSI. The SCSI is visible in the BIOS and is visible in Windows, except it does not have a drive letter. I set up a partition on it with a drive letter (did not format), but now it says the drive is not formatted.

I used this drive as a backup and have data I can't lose. Anybody know why XP suddenly doesn't see the drive properly? Any solution to getting this resolved?

thanks
Fred
