I have a RAID 5 with 4x1TB. It warned me to replace soon, and I've done this before with no issues. Today I ran the Validate command on Volume MEDIA just because I used it recently. After 20 minutes the Mac froze. I restarted it and when I logged in it says (RED X) OS X Can't repair my Drive MEDIA. I click OK and the icon looks inverted. SoftRaid says it's rebuilding, been at it 3 hours but I can't access the drive. Some folders show up, some are blank. All is read only.
To make matters worse, my Seagate (never buy seagate) time machine failed.
Help!

UPDATE:
Ran Disk Warrior and rebuild the directory structure which resulted in file and project loss. I'm not sure why the Validate command locked up my mac, maybe because of the bad drive? The problem is no longer an issue.

Sorry to hear that DW could not repair your project!
Yes, it is possible the bad drive hung your system, at least it is a plausible theory.

Since it froze the mac, including the mouse, why would the drive have corrupted? Because the validation was interrupted?

I dont think it was related to the validation. If it was, it was not the validating, as much as the I/O activity going on when the disk failed.
All a validate does is read from all the disks (and if the parity data needs to be recalculated, it is updated), so nothing actually changes on the volume.
When the machine hung, it is possible there was data in RAM, or perhaps the disk cache that did not get written out. Its guesswork. But it is odd that your project was sufficiently damaged that Disk Warrior could not repair it.

I think all the files are there as there is a "Missing Folder" with 400+ sub folders. And filenames have weird characters after them. Thank you for your insight as to what might have happened. I'll remember to check my backups before pulling a disk out.
