Good disk, but bad housing

I bought the hard drive for PC backups, a task which they initially met very good and reliable. It was used only about 2-3 times a month. She was going very fast and relatively quiet thanks to USB 3. Very occasionally they lost time to connect to the PC and had to be re-inserted again, I thought nothing of it but.

Suddenly then each read or write attempt has been acknowledged with IO errors. The warranty period had already elapsed. The SMART values ​​of hard drive were always discreetly.

Since the hard drive so now was useless, I wanted to open it to look for the error. The housing defied, successfully any attempt to I left it finally with a screwdriver and a hammer. The hard drive contained was in perfect condition, but when I held the board in his hands, I could not believe my eyes: She was completely covered with red rust, parts were crumbling to the touch.

I then bought a new external hard drive and built-in hard drive and everything ran perfectly again.

Conclusion: It is probably a production error. For the resulting anger and subsequent costs (new housing), there are two star deduction. More deduction is unjustified since the internal hard drive still running error-free and relatively easy "fix" the problem was.
