Darn Hard Drives

Hi!

I have 2 SATA HDDs, RAID 0. Both are Maxtor 120GB.
I tried to see whether i should defragment (i clicked 'Analyse' in that windows defragment thing). It told me i needed to run check disk /f.

I tried to scan for errors, but it told be that the disk checker needs exclusive access to files, and that i needed to restart to do that.

What does this mean?

And furthermore, what does it mean if my computer had just crashed, and upon restarting, telling me that my raid array was offline? (I restarted again and it was fine though).

Is there some sort of HDD analysing program that could tell me what's up?


Bloody hard drives. I just don't have the money for failure right now! Oh, and theres no way i can "un-raid" this without reformatting huh?


Thanks heaps.
 
Chkdsk can't run on the same drive that windows is running from and any other open programs that may have files and won't relinquish their hold on them for it. If you run chkdsk with the /f command, it should queue up a check for the next time you reboot and then run the check before windows actually starts so it gets that "exclusive access" (which basically just means it needs to get to parts of the harddrive that are locked down for access to prevent things from messing up.)

I don't know about raid arrays I'm afraid, sorry. Maybe the next person knows more. I'm guessing the software part of things thought there was an error and was using the array in more of a safe mode kind of thing or something, so rebooting reset the software and it detected no errors the next time around. Crashes should cause errors since unwritten data doesn't make it and data in the middle of writing is incomplete, sometimes even filesystem damage occurs.

As for analyzing, well, that depends on what you mean. You can run scandisk and tell it to do the surface scan (or whatever microsoft is calling it these days, who remembers) if you think you're looking for damaged spots on the physical drive. If you just want a better defrag or something, well, seems like most people recommend O&O Defrag as a good choice (I tried it before and it is better than the ms junk. Don't know if it's better than the alternatives or not.)
