I recently (within last 6 months) installed a WD 1TB Black (WD1002FAEX-00Z3A) in my tower to use as my main storage for files, I'm running most programs and windows 8 off of a 120GB Samsung 830.

Recently the drive WD 1TB seems to slow tremendously. When I will try open folders or files on the drive, it will sometimes take forever and sometimes not even open the files. Drive has this problem only intermittently. Passes SMART tests and the passes the extended test with WD Data Lifeguard. WD agreed to RMA the drive, but it's a pain in rear. Is there anything I could try first to find out and maybe fix what the issue is?

Yes, if you take the drive out RMA it -- the big Google HDD study back in around 2007 showed that SMART does not reliably predict drive failure, in that many drives failed without SMART warnings (but SMART warnings do indicate probably imminent failure).

"Google team found that 36% of the failed drives did not exhibit a single SMART-monitored failure. They concluded that SMART data is almost useless for predicting the failure of a single drive."

Have you checked to see how fragmented it is? How full is the drive?

The power settings are to turn off the disc 'never' so I don't think that is the issue.
I don't know much about hard drives, but I would think if the drive was failing that it would show some issues in the tests that I ran.

WD suggested replacing the power and data SATA cables to see if that helps. Sounds like a pain, and if I'm gonna take the drive out, I might as well just send it back to them.
