I have bad blocks in event viewer on a drive, so I am going to replace that drive. The drives in the box are IBM something. I unplug the last disc on the SCSI cable and the NT box does not boot. During the boot process i can tell it is a AHA-2920 SCSI card. I can also see that when the old drive is plugged in there is SCSI ID 0 - DISK0, SCSI ID 1- DISK1, SCSI ID 2-DISK2, SCSI ID 3 - DISK3, SCSI ID4 - DISK4. The NT box has a software RAID5 stripe set with parity.
The first disk, disk 0, has (1GB) c: and the winnt direcotry. The rest of disk 0, 16374 MB, and disk 1,2,3,4 (16374 MB) are in the stripe set with parity (drive d:).
On disk 4 there is an extra 1024MB left over being used for drive G: (which is a primary partition, not sure if that makes a difference or not).
when I plug in the new drive, which is not the exact same drive, the new drive is a Seagate Cheetah, ST-318404LW.
I notice the ID's are different.
with the new drive, it starts with SCSI ID 1 - disk0.
and the new drive will be SCSI ID 8, but it is seen, however the NT box does not boot.
It only says PRESS ANY KEY TO REBOOT.
as much as i can tell I might have a jumper or pin differnet with the new drive, maybe with the SE (single ended bus) or something, i am not sure, which is why I am posting.
for a couple pictures on what my disk administrator looks like on the NT box, or a pic on which jumper I used go to
yes I do have a recent full backup of htis box, differentials since the full, however it is 60 GB of compressed images, and differentials since then. It would be better if I can fix this than just redo the drives and restore from backup.
Thank you in advance for any assistance. If you have any questions, please post.
