Hi,

I have a RAID 5 in place. One of the hard drives failed. I have since replaced it but I have found that it is configured as an Ultra 2 80MB, not Ultra 3 160MB. The hard drive is identical to the other 2 as I made sure that I was getting the same specs.
How do I change the configuration of this hard drive without affecting the data?

What I have found is that when accessing the C drive, it takes forever to open up.

Look forward to a response.

Regards

Mil

If I read your post correctly:

Whatever the original three drives were will be the size of your new drive, even if it is bigger. That's just how raid 5 works.

If I interpret this right either your BIOS isn't seeing the disks for what they are or someone replaced old 76 GB disks for 146 GB disks one at a time withour rebuilding the array.

Either way - get the data off ASAP, blow the array and re-create. If it doesn't see the disks properly update your SCSI card bios or replace the card.

The scsi interface is not dependent of the data layout as long as you don't change the size.
All your connected disks and adapter have to support the Ultra 3. I would not recommend mixing Ultra 2 and Ultra 3 on one scsi cable.
