I have a Thinkpad with a SAMSUNG MZ7TD128HAFV-000L1 SSD, running Windows 7 SP1.
For the past week or so I've experienced frequent hangs at log on and log off. The screen is blank and I have the loading cursor spinning but nothing else. Ctrl+Shift+Esc does nothing. Only thing possible is to force shutdown with long pressing the power button, and start up again. Then I am presented with that Recovered from unexpected shutdown screen (boot into safe mode or normal etc.).
I've run chkdsk a few times and it turned up nothing... for a few days the problem even seemed cured. But after the latest incident a chkdsk started by itself at boot. This time it found something to do, recover some orphaned files:
CHKDSK is verifying files (stage 1 of 3)... 304640 file records processed. File verification completed. 438 large file records processed. 0 bad file records processed. 2 EA records processed. 54 reparse records processed. CHKDSK is verifying indexes (stage 2 of 3)... 408438 index entries processed. Index verification completed. CHKDSK is scanning unindexed files for reconnect to their original directory. Recovering orphaned file LASTAL~1.DAT (73092) into directory file 2245. Recovering orphaned file lastalive0.dat (73092) into directory file 2245. 2 unindexed files scanned. Recovering orphaned file LASTAL~2.DAT (73107) into directory file 2245. Recovering orphaned file lastalive1.dat (73107) into directory file 2245. 0 unindexed files recovered. CHKDSK is verifying security descriptors (stage 3 of 3)... 304640 file SDs/SIDs processed. Cleaning up 48 unused index entries from index $SII of file 0x9. Cleaning up 48 unused index entries from index $SDH of file 0x9. Cleaning up 48 unused security descriptors. Security descriptor verification completed.
Is it a sign of SSD failure? Is there a way to test this to confirm?
Repaving is NOT desired, I've tweaked the OS in too many ways, do not suggest blowing away the system to put on a fresh OS and "just reinstall programs" like it's all in a lazy afternoon's work. I've ordered a SATA-USB3 adapter to help mirror the drive onto a spare SSD. Didn't want to mirror everything (caches, crud, maybe this bug itself?) but selective backup of system configuration and user state is not within my grasp now. I hoped to make a boxstarter script but sooo many tweaks. Any advice here is appreciated.
