Hello,

I have a 4-disk (WDC Green 1.5TB 64MB) RAID-5 Array (onboard controller on a Gigabyte P55M-UD2) and while copying some files, I got a warning from the Intel Matrix Manager that one the disks had failed and the array was degraded. This is all on Windows 7 x64.

I then reboot the computer by first shutting it down completely and the hard disk that was indicated as failed seemed to be OK in the Matrix Manager but the array was set to Rebuild status.

It's been now rebuilding for half hour or so and it says it needs another 97 hours to rebuild the array!!!

Is this normal?? Is the disk really failing or is it just a hiccup?
 
could have been a hiccup, to be safe i'd run a full diagnostic on it as well as zeroing it before the rebuild.

To do that without risking your current array you're best moving the failed disk to another comp.

In the manager, does it say the array is normal or something else? When you boot up the PC does the RAID startup indicate the RAID is normal?

After the reboot it says it's normal yes - when I first got the warning it gave a bad "mark" on one of the disks.

I left the rebuilding running all night and it's now at 10% - another 72hours it says :S
 
Rebuild time is the major issue with having such big disks, you probably dont want to run any tests on it while its rebuilding though :p
