Windows 7 - SSD problems?

Two weeks ago I had problems with Windows backup not completing and returning an error.

To counter this I ran a CHKDSK on my Vertex2 SSD RAID. Phases 1 to 4 ran without a problem Phase 5 however came up completely garbled.



I have posted it here as I have never seen anything like this before. After CHKDSK was finished. I ran it through again and got the same result.

I then proceeded to break my array and wiped the drives. Ran CHKDSK on them separately and they both passed. I also checked both drives for health and they passed with 100% I then rebuilt my array and checked again, they passed without a problem. I loaded Windows from a backup image and have let it run for the last two weeks and not had another problem.

I thought at first that I had a bad disk/controller but now I am certain that they are both OK.

Apart from Windows backup and CHKDSK there was no other indication of a problem which is strange considering the implicated damage to the drive.

I have had time to think this through and now believe it to be normal behaviour. I think the problem may have been caused because CHKDSK expected to find empty space, but as trim does not work on a RAID it got a surprise. Windows backup also noticed a problem as it refused to work.

Can anyone shed any light on what happened? I am open to ideas and am particularly interested in hearing from any one who has run a SSD without trim about problems and bad experiences that they have had.
