During a recent power supply failure, the boards on 3 disks in my 4-member ICH9r RAID-5 array literally fried. I believe that the data on the platters is ok, that it's simply the boards that are finished.
Losing the data would be a disaster.
After the smoke had cleared, in a panicked craze, I pulled the drives out of the system but forgot to note which drive corresponded to which port. Now I am trying to reconstruct the array by imaging the individual members to new disks by exchanging the good disk boards I have (one from the good drive and one from a spare) for the burnt ones, one at a time.
This is leading to some confusing observations and questions:
1. What does a single array member look like to the Windows disk manager? Two of the disks show up as "healthy" partitions and two show up as unallocated space. Is this because only two disks carry the information needed to initialize the array or is it a sign that the data may be damaged?
2. Even sector-by-sector images of the old disks do not show up as array members. Does ICH9r rely on a drive's serial number to identify its position in an array?
3. If the drive serial number is important, then one option is to create a new array with the new disks, then clone the old data to the new array. If I do this, will the ICH9r controller "remember" the serial numbers of the old array, just in case I need to try restoring from the original disks (e.g. if I find a replacement drive board?)
4. I will pay good money for a Maxtor/Seagate 250GB 3.5" SATA Drive, P/N 9FV132-327, Firmware 3.AAC (no other FW works).
Many thanks for any help!
