This is one of the issues of such a RAID setup. The owner may balk at replacing a failing drive. To run the drive maker's test proper we have to place it as a single drive and run the test. Often wiping the data.
Sorry to see yet another person tormented by this issue.
In closing, let's say it pinpoints the error to something specific in the drive. Since repair of the drive is done by replacing the drive, such detail is not needed. We only need to know that the drive failed the maker's test.
I recently installed two new 80Gb Samsung P0812C Hard Drives (SATA) into my self-build PC, intending to set up a RAID(0) array.
I now have Windows XP running on my older Samsung HD080HJ (SATA) hard drive, and the two new drives on the RAID array, with one partition at 90Gb and one at 55-or-so Gb. Onto one went my programs (leaving the Windows drive as empty and as 'clean' as possible) and onto the other partition went my documents, backups etc.
Now, a mere week after installing the two new drives, both my DOS RAID utiltity and my Windows RAID utility are saying that one of the two new drives within the array are close to failing, and that data on them should be backed up asap. (This has been done).
I used Windows disk checker to scan the disk for phsyical errors and bad sectors, which returned a few errors and solved them but has not fixed the problem.
I downloaded Samsungs Hard Drive Utility tool from their website, and checked both disks- one of them is indeed having write and scanning errors; however it's not provided me with any analysis of the problem- is it a returnable fault, how soon/likely the disk is to fail etc.
I've tried two different SMART tools to examine the status/fitness of the disk, but neither is actually able to provide any details on either of the two drives that form the RAID array.
My question (sorry about the lengthy introduction) is twofold:
a) Is there a utility that can utilise SMART data from a drive that forms part of a RAID array?
b) What's the best course of action with regards to my array? Return the drive, thus breaking the array and forcing a data restore, or attempt to discover the source of the drive's problem and check for some kind of fix?
Relevant hardware and software setup is as follows:
Intel D925XECV2 Motherboard
Intel 82801FR SATA RAID Controller
1x Samsung HD080HJ 80Gb HDD
2x Samsung P0812C 80Gb HDD
Windows XP Professional SP2 and all up-to-date patches
Intel Matrix Storage Console
Intel 82801FR SATA RAID Controller (at DOS/BIOS level)
