My experience tells me that one of your disks is slowly undergoing serious corruption. Thankfully most modern disks have a built-in hardware monitoring system called SMART and special programs are able to read this SMART info (even for external USB disks).
Therefore I'd recommend downloading a trial version of Hard Disk Sentinel (Hard Disk Sentinel - HDD health and temperature monitoring) and performing tests on your disks. Only if HDSentinel says their health is 100%, then it makes sense to look for software (Windows) problems.
Tanks and good point. the tiral version however doesnt provide the required tests See: Hard Disk Sentinel store
The other tests I ran to date all passed.
