I recently noticed Windows was extremely slow and some programs failed to run.
The hard disk is checked during boot randomly. Sometimes checks go to Stage 5: 100s of thousands of sectors.
After a check, my secondary partition was inaccessible. Upon changing permissions, I was able to gain access, but all my data was gone to folders like found.000, found.001 inside chk*. I also had Ubuntu installed in another partition, which refused to boot now.
Reallocated sector count is 880. The temperature stays above 50°C. Is this a hard drive failure?
I formatted the disk and reinstalled Windows. BSOD with error code MEMORY_MANAGEMENT happens randomly.
Here are the details. Even though there is no critical SMART warning, I doubt this is a severe disk failure.
EDIT: The System is now not booting. Windows BSOD with Error Code: CRITICAL_PROCESS_DIED, which is followed by Windows Automatic Repair (which fails).
