Does this sound familiar: Now insert the disk into drive A: !!! As drive A: ??? But I had no drive A :, knew it even a drive that swallowed floppy among other 3.5 inch existed in the history of the computer. So read on to Amazon, review and decide directly on this drive and I have to say I am thrilled that part runs flawlessly, can be installed without problems. I can only give full marks, and it was delivered Ruck Zuck, one should mention perhaps ;-)
