I bought this hard drive 2x, even though there were some negative reviews. The drive was installed once on Windows XP and even Windows 8 / 8.1 computer. The hard disk could be set up in no time, format, partition. There was no error. It can be heard no running noise, you have to close approach to the ear to the hard drive to listen to them at all. They run reliably ever since with no problems, just as you would expect from Western Digital for many years. I had then begun with a 20MB Western Digital hard drive SCSI. I can only recommend this drive to anyone, it's worth it.
