had a major problem with my Raid 5 yesterday. Adaptec Controller showed all 4 drives with status failed and the array was on failed too. I used raidutil to force it back to optimal state after reboot didn't help at all. Windows made a chkdsk and it found the two partitions of the raid and all the files were still there.
Is there any way to find out why the Raid and all drives failed? Could it be that some broken tape in a tapedrive on the same controller caused all the troubles? I did get timeouts from the tapedrive when i tried to eject the tape and short after this i had the crash.
How to check if the drives are broken and have to be switched and how to check if the files are still working after i got the array back to optimal? Will the Adaptec Storage Manager check this for me?
thx for the answers in advance. Tobsen
