Excerpt: Not wanting to throw away my old Mac Power PC I was looking for a cheap drive to keep it running. This worked great. After reformatting and instaling operational softwre my Power PC runs like a champ.
Summary: I purchased this to replace my wife's failing HD. No problems with the install or the operation of this HD. For the price this was the best HD I could find. I would recommend this to anyone who needs or wants a new HD.
