Is this your system HD or a secondary HD? What operating system are you using? If windows, did it load a generic driver or did you use the manufacturer's driver?
If windows, open task manager and see if you can find anything. If WIndows 7 open resource monitor to see if anything is accessing the drive excessivly, and also do a chkdsk.
Maybe check OCZ's website for a firmware upgrade. And also check your motherboard manufacturer's site for a BIOS upgrade for this issue.
