So, I bought a cheap 2,5 inch USB 2.0 external HDD case the other day. I put a very old 320GB laptop drive there, and although it worked very slowly at first even almost stopping the entire system I've ultimately managed to format it and use it for a while, but then just one day when I plugged it in it displayed itself as unformatted, prompting me that it needs a format. So I assumed it's because it's an old HDD and it was bound to fail at any time.
I swapped it for a different newer 1TB drive that has never had any problems and had files already on it, and the same happened randomly a few days ago too. Is that even possible? Could a cheap external HDD case actually be at fault? I was able to recover files flawlessly using a disk recovery program but this is very inconvenient.
