Playback issuse - file transfers freezing - harddrive failure

Hello all looking for a little help,

Started experiencing playback lag on most movies that were stored on my E Drive which is a 500gb western digital, taking a movie off that harddrive and placing it on my C drive(150gb WDraptorx) sometimes would hang during the file transfer for 10 minutes then start up again. playback would be smooth if played from my external or main c drive , so i thought this could be my E drive was failing, so i tried a disk check over night but was only 10% when i got up and didn't seem to be moving at all.

1week later i get a BSOD and freezes for 15 minutes so i did a hard reset, freezes on loading screen for windows and BSOD once again, once is started up in bios got windows is missing a certain file and prompted me to system restore and was freezing every couple of minutes but completed successfully. 2 hours later i get BSOD and BIOS reports the C drive as BAD. did a check disk for it and had a ton of unreadable sections but it completed, haven't been able to get back to windows since. ATM am trying start up repair but its already on 2 hours +.

This computer and its hard drives are 6 years+ everything is hooked up via SATA connections.

Should i take the main drive out and install windows on to my secondary or is it possible that they are both failing and should just purchase a new hard drive.

Rectify a Damaged Hard Drive

Sometimes the cause of BSoD is a faulty hard disk. Most Windows operating systems have a diagnostic scan for the hard drive, and you need to run this to figure out the problem. Sometimes the operating system will encounter a problem where it is unable to read from the hard disk, and in such cases apart from the hard disk, you also need to check out the SCSI (Small Computer System Interface) terminator.
