This is the second disk That I recevoir and the 3rd That I will return. Unfortunately, the disk Makes a lot of noise, it is very hot (abnormal for a WD Green) and when to I use the WD Data Lifeguard Diagnostic tool (the long extended test) I recevoir answer - 08 Unable to repair bad Sectors. This of course means clustering That Does not all WD disks are bad. I have 8 of 'em, all works till now very good. Just When You will recevoir disk, do a test extended.
