"Master File Table" error on new Samsung 850 EVO NAND SSD
The customer was in the middle of reading some Data from ISO Images mounted with UltraISO. Apparently, in the middle of reading the data he got the BSOD that means "Drive can't be read" (0x000000ED) and could not re-boot. I tried to check the Drive using CHKDSK and that's when I got the Master File Table error.
This was a brand new drive with a fresh install of Windows 7 x64, it had been running perfectly for a month. This error happened in the middle of a windows session.
The only software that might have caused this was Perfect Disk v13, which I assumed would be OK for optimizing SSD's. But I had that scheduled to run only between midnight and 6AM. The machine generally stays on 24/7, maybe shut down during weekends. But this happened in the middle of the week.
I ran Partition Wizard 7.x to try to recover the drive, but it failed to fix the error. I had used that to repair one partition on my main machine about a year ago, but that was not the boot partition.
Is there any tool that can check a disk that has Master File Table errors? Else I just have to re-install Windows. But I need to know what caused this so it does not happen again.
The Machine is an AMD CPU, I'm not sure which one, probably an AM2 CPU like a 4400+. Sorry, I have no logs for it, they are all on the unreadable drive. What would cause a drive to go out like that, could UltraISO cause it when accessing mounted ISO images?
TIA.
