Various standard-issue SCSI suggestions: Try limiting the SCSI transfer rate for both drives. You can do that in the Adaptec firmware utility. Start by just picking the slowest setting that isn't ASYNC and see if it works then. Check to make sure termination is proper. Both ends of the SCSI chain and nothing in-between. Check all the drives and the controller for this. Weird things can happen when termination is improper -- including everything appearing to work fine for years. If you can, try an external terminator. If you have one, try a different SCSI cable. See if either drive is jumpered to generate SCSI parity. If they are different, make them the same. Try both ways -- generate parity, and do not generate parity. See if either drive is jumpered to generate termination power. Try disabling term power on all drives. Try enabling term power on just the drive closest to the end of the chain. See if either drive is jumpered with a different block size, or a capacity-limiting jumper, or any of those other weird compatibility hacks drive manufactures put in. Try different SCSI IDs for both drives. Try with both drives together this way, and one at a time. See if there's a pattern to the failures there. If you put each drive in the system one at a time, and boot from CD, does the CD OS see the drive properly? > still get medium errors to the original drive that i know is good! Are you sure it's good, or do you just believe it is good because it doesn't fail to boot in some circumstances? You may want to try running a media verify (from the Adaptec firmware utility). -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
