4 of WD RE 4 TB Enterprise Hard Drive: 3.5 Inch, 7200 RPM, SATA III, 64 MB Cache - WD4000FYYZ
Sold by: SabrePC
All of these drives began failing in the last week (approximately January 18). One has completely crashed and the remaining three are throwing smart errors and bad sectors increasing. The MTBF for these drives is over 1.2 million hours, so the fact that they are all failing now is problematic.
They are covered under a five-year warranty. We purchased the drives on July 25,2015, so they should be covered until July 25,2020. We've contacted WD who stated that since SabrePC is the OEM distributor, we have to request the replacement through them.
Sabre denied our OEM replacement request saying they did not ship these drives. The only problem is we tag every drive we receive with the purchase location and original serial numbers. These drives were the ONLY model we had shipped to the specific site, the actual only time we even purchased this model of drive. We typically use WD Red, but this site had a requirement for a higher MTBF.
Furthermore, to prevent issues we even take a picture of when the drives arrive along with the original packaging and serial numbers, which show they came from SabrePC.
Lastly, they are the only vendor we ever purchased this model of drive from, so it made it very easy for us to track down.
