(ok initially i didn't plan on asking this...but...= A =" sorry)
...ok the external HD wasn't exactly dropped...but it did get hit so...
ok i got an astone external HD (bought a new one after so long)
last night, while i was holding onto its outer leather casing (you know, sometimes external HDs come with some outer casing) and the wire, the external HD slipped out of the casing and hit against a wooden cupboard approximately 5-10 cm away. (thickness of wooden cupboard: approximately 4cm)
today, when i plug it into the computer, the computer is able to read it, there hasn't been any funny noises coming from the external HD, the computer can still read the external HD, it's not lagging, i can still transfer stuff in and out of the external HD, stuff can still be extracted from winrar. files without any errors and it still can be safely removed. i have yet to check if all the files in it have been corrupted, or whatnot.
1) should i still be worried that there's something wrong with it's insides?
2) is there anyway to ensure the internal health of my external HD?
3) (ok this might be a really strange question to ask but...)
how many times can an external HD be dropped from a table before any internal damage can be noticed?
4) usually when an external HD is dropped, will signs of internal damage start showing immediately (in less than 30mins), average (1-3 days) or a long time (a few weeks)?
