I strongly recommend reading my posts on the limitations and risks to your data of running CHKDSK, using "repair" options, etc. It can also render data irretrievable, or people have too high expectations as to exactly what

I'd recommend getting using the hard drive's manufacturer's test tool, and/or a hard drive test/diagnostic tool like freeware HD Tune, HDDscan, Passmark's DiskCheckup, and others. Those are available on trusted download sites like majorgeeks.com
, cnet's http://download.cnet.com/windows/,
and so on.
There are also self-booting diagnostics that can test a hard drive in case the operating system itself has problems booting reliably because it is located on bad blocks/clusters. A good one is
UBCD. You download it and burn it to a CD, DVD, thumbdrive, etc then boot from it and run the hard drive related tests. See warning below.
The drive diagnostic programs may be able to run a drive test and identify specific bad blocks on the drive. In addition, they add value in that they can also interrogate your hard drive's accumulated SMART data (assuming your hardware/software support it), and determine if the drive is reporting values that are below or exceed required values (for example, it can show you if the HDD ever exceeded its maximum operating temperature, or it's showing too many read errors, and so on). See my posts for more info. Some of it is redundant.

[/b]WARNING: be very careful when running hard drive tests, as some programs or program test options will WRITE over your data, and it will not be recoverable. Generally sticking to read-only tests is sufficient (and safer) to uncover most HDD problems.[/b]
