I purchased a WD7501AALS a couple of days ago and ever since then I’ve been having problems. Sometimes the HDD disappears from My Computer and Disk Management, other times it is extremely slow when accessing files. Sometimes it will transfer at 100+MB/s, and other times it will drop significantly, freeze my PC altogether, or at the very least prevent me from opening and closing processes, forcing me to do a hard reboot. Checked the S.M.A.R.T. status earlier and it passed. I ran chkdsk and an extended diagnostic, all came back good. Also, I just tried to save a file and got this error: “The request could not be preformed because of an I/O error.”
Any ideas? Thanks!
