Summary: This is a review of a hard drive I have had for several years. I waited to write a review until I could see how this drive worked in the long run. It has now been running continuously for over 2 years and has not failed. In the mean time I've had 4 - 1TB drives (Maxtor and Seagate) that have failed within a few months of use and had to be exchanged (which both companies honored their warranties). It may not be gigantic like the newer drives, but it is reliable.
Summary: This version is intended for the "techies" that know what they are doing, thus the "OEM" tag. The drive is completely clean w/o instructions. I bought it because PATA drives are rather limited in choices now and I needed to upgrade my older laptop from an 80GB to this 250GB. Also the price was good.
Summary: I bought this drive because I wanted a LARGE PATA drive to upgrade my Compaq nc6220. Preferred retail packaging, because I thought any necessary screws, jumpers, software would be included. This is not the case here, so I subtracted one star for this. However, the retail packed drive was STILL CHEAPER than the OEM packaged drive. Inside the fancy retail box is a note that says basically "If you don't know what you're doing, get help and good luck.
Summary: I installed a WD2500BEVE in a 2005 Mac PowerBook G4 in December 2011, and I noticed fairly quickly that it seemed to be running hotter than the OEM drive, even when the computer's cooling fan was running on high. (The hard drive in a PB G4 lies just to the left of the track pad, so I could feel the heat when I rested my left hand on that part of the case.) In July 2012, the computer started locking up repeatedly. Apple Hardware Test ver.
Summary: Warning!! Buyer Beware. These are refurbished/Recertified drives. They come in new boxes. They appear to be new and are sold as new but they are not. They even went through the trouble of placing a barcode over the recertified marking on the label.
