TODDLT Posted November 14, 2013 Share Posted November 14, 2013 Sorry if you already read this, but I threw it in the wrong forum. I have requested the other be deleted. For a non-enterprise drive, how long would you trust it? years? power on hours? I am replacing a 2 TB drive with a 3TB drive due to space and use. I am contemplating re-using the 2TB, but it has 12,500 power on hours and could be 5 years old or more. Would you trust it or just move on?

garycase Posted November 14, 2013 Share Posted November 14, 2013 The SMART data looks fine -- and 12,500 is not all that many hours. I've got several drives with over 40,000 hours, and a couple with more than 50,000. Link to comment

bw1 Posted November 14, 2013 Share Posted November 14, 2013 I don't think a WD20EARS drive could be more than 5 years old. I think they were just coming out 3 years ago. I bought 1 WD20EARS and 1 WD20EADS in Oct 2010. I have 2 WD20EARS drives that have just over 16000 hours. You can check the manufacturer date by removing the drive from the server and checking the label. You can also enter the drive's serial number in the warranty check on Western Digital's site: http://websupport.wdc.com/warranty/warrantycheck.asp?custtype=end which would tell you the warranty end date and give an idea of it's manufacturer date.

c3 Posted November 18, 2013 Share Posted November 18, 2013 Depends on your re-use situation. If you are moving it from parity to data drive, it should be fine for possible a long time. If you are now going to use it in a workstation, in a different orientation, different temperature stability, you might find it failing quickly. Link to comment
