Hey guys, I own a 2TB external HDD by LaCie (2 HDDs in a casing, each 1TB), It was dropped yesterday from my bed which is about 40-45cm high.
The HDD was dropped while it was off. I have NOT turned it on after the drop because I can hear a strange sound from both drives BUT I am not sure whether this sound was always there as I've never put my ear next to the drives and shaken it before, this is why I am asking here as I know you're experienced in this area. I have recorded a video of the sound it's making below, can you please tell me if this is normal and I should turn it on?
Here is the video below, please turn your speakers up. This sound is only produced when shaking it quite hard, but moving it around normally it makes no sound. There is also another sound which cannot be picked up by my camera, but when I put the drives close up to my ear I can hear a very tiny squeaky sound only when rotating the HDD, pretty sure it's the disc rotating, is that normal, since it's a 1TB platter?
the power was off so the head should have been retracted. Shaking it is not a good idea, you will hear the heads bouncing around (a normal sound if you shake a HDD)
I would bet the drive is ok, if you broke a head off of it's support arm you will know pretty quick when you turn it on. The broken head will dangle onto the platter and bounce between the platters when the platters spin.
power it on for a second to get the platters to spins. if it sounds ok, just let it run and see if you can get data off the drive. Sometimes dropping the drive will cause a drive to become misalignment that will cause sector read errors. (to fix misalignment you have to do a full format of the drive to get the heads to put down new sector markers on the platters)
Does it still work on your computer?
The dropping drive can be good or bad. If the drive is physically damaged, you can never fix it for future use. If the drive is logically damaged, you do have possibility to use it after re-formatting it.
Therefore, you should run the Error-checking tool to ensure: Randomly right click a partition in “My Computer” to select “Properties”=> Open “Tools” tab and hit “Check Now”.
Luckily enough, you could try a drive recovery freeware to get back your inner data and format it afterwards, if your drive is logically damaged.
Unfortunately, you'd better take it to an expert for saving your inner data, if it is physically damaged.
TBH I think a friend and I dumped an old IDE HDD out of a fast moving car once just to see and when we didn't like the bounce we got on the first run (just rolled off into the grass) we did it again! and man that thing bounced higher than 2 cars and it still powered up ok without sounding internally broken. just couldn't connect the IDE cable coz the connector on the HDD was mangled.
