Summary: Moved away from the other major hard drive brand that sounds like oceanmate. Had nothing but problems with their drives. Still have a stack of dead ones. I have had good luck with WD Black drives. Thought I would try the Blue drives. The Blue drives don't seem to have the same quality as the Black drives. Live and learn. Another dead one to become a door stop.
Pros: Worked fine for 1 1/5 years. Then the problems began.
Cons: The Win7 Ent build started having problems with Outlook and Word locking up. Thought it was the software. No software fixes worked. Decided to uninstall / reinstall Office. Would not uninstall. Did an easy transfer of user profile and data. Started Win 7 reinstall, fresh install. Install succeeded overnight, next morning a window telling me the hard drive had fatal errors. Rebooted Win7 and that was it. The OS never loaded again. Hard drive dead.
Summary: I used this drive for 4 years. Then suddenly it failed completely. I had to install a new drive and restore my data from backup. WD claims these drives have a 1,000,000 hour MTBF (Mean Time Between Failures) -- Don't believe it! Less biased sources say 50,000 hours, and my personal experience was 35,000 hours.
Summary: WD replaced first with WD5000AAKS, second replacement, WD5000KS.. Be sure to register your drives with WD when you get them. One remaining drive (not replacement) making recurrent sound of winding down but no obvious performance problems. Ran WD boot CD diagnostics (short version) on each drive before 2nd drive went bad but nothing showed up. 22-JAN-08 number 3 died today. Still have noise. Mar-08 4th and last drive died. Replacement noiser than ever.
Summary: Сперва данная модель HDD радовала скоростью и емкостью, но через 3 года начались проблемы. DC++ и торренты загоняли его всего за год. Периодически винт стал тормозить и отваливаться прямо в процессе работы. Пришлось переписать с него всю важную информацию. В общем, хоть это и WD, но модель крайне не надежна.
Summary: Стоит такой у сестры, глючит постоянно! Шлейф постоянно отходит, а недавно стал конкретно виснуть. Винду переустанавливал часа 4, хотя обычно на это нужно часа полтора. Пока не передернул шлейфы, не ставилась ни в какую, все какие-то ошибки записи. В общем неудачная модель.
