My WD10EACS failed and I was not able to access any of my files or pictures from it. It is a 1 terabyte hard disk with SATA interface and is easily recognisable as it is part of Western Digital’s Green Power range – so the label has bright green areas on it. It is regarded as green because it spins more slowly than normal drives and so uses less power. What I know now that I did not know then is that the slower spinning makes the data transfer slower as well. You can decide if this is a reasonable trade off for your circumstances. The drive came out in early 2008 and did its job well for us until access stopped one day. After professional data recovery, we got our data back and some home truths about hard drives. Firstly, all drives fail eventually. Secondly, no one can accurately predict for a single drive when it will fail to within one month. Thirdly – even if you back up every night like we did, that can still mean you lose a complete days work when any given drive does fail. While it wouldn’t have been the end of the world if we could not have got our files back, it was well worth the money for the recovery.
