I have a fairly new system, built within the past couple of months, based on a DX58SO2 with an i7-990X. I used a 256gb 510 SSD as the system drive, and have a RAID 10 array for data. Since building it the drive has been fine, but on Friday night I began having a few issues with Windows acting a bit flakey (system is normally on 24x7), so I rebooted.
When it came back things felt... slow. Like I was using a normal hard drive instead of an SSD. But I didn't think much of it and went to bed.
Fast forward to Saturday night. That day's Windows Home Server backup failed (no error given), and over the past couple years I've learned that usually indicates that there's an error in the filesystem that needs correcting. Since the whole PC is still feeling slow, and I had an odd error in Windows Live Mail about a corrupt folder, I load up the SSD Toolbox to check the SMART status. No errors, so I schedule the drive for chkdsk, and reboot.
Chkdsk soon give me an error "File record segment #### is unreadable. There's 8, all in a row. It goes for a while, and finishes all files records, but before doing stages 2 and 3 it reboots. Now it finds more "unreadable" errors: 4 groups of 8 sequential segments. It finishes, and goes through stages 2 and 3, correcting a couple hundred of corrupt attribute values.
Reboots again - no Windows. It just spontanously reboots and wants to run Startup Repair. I let it go through the "repairing disk errors" stage for over 4 hours - it says it MAY take an hour. There's no progress indicator or list of things it's done, so I give up and try again. It just does Startup Repair over and over, whether I pick normal, safe mode or whatever.
So I move the drive over to another i7-based Windows 7 PC. It detects the drive as "RAW" file system and claims the drive or folder is corrupt or unreadable.
I run the SSD Toolbox's "quick scan". Read passes, data integrity hangs. Cancel that, try the "full scan" within a few minutes it comes back as failed - contact Intel. Good thing WHS has a backup from 2 days ago.
For fun I give chkdsk another go. There's now 40 unreadable record segments (another group of 8) and the rest of the errors number in the tens of thousands - a constant scrolling screen of errors for over an hour. I let it finish, but the system still sees it as a corrupt drive.
Since I wasn't sure whether the fact that the partition seems corrupt was at fault for the test failure, I delete the partitions, try a Secure Erase - works - and then try re-creating a single partition. No matter what, it just hangs trying to create the partition with the drive light on solid. Rebooted, tried a couple times, same issue.
SMART reports a total of 74 reallocated sectors. The drive is less than 60 days old and the reported writes were 1.73TB before I started, and 3.1TB after all of the chkdsk and system repair attempts (seems like a huge increase).
So... seems to me that it's good and dead. Any thoughts, since my weekend is now wrecked and I can't do anything till Monday?
