As the title says i dropped a Western Digital WD7500AAVS Sata2 HDD(750GB) before even trying it out xD (ZOMG). Despite it only fell like 20cm i cant get it to be recognized by my computer. After I turn it ON it starts to boot up than makes sounds that freaks me out >.>, maybe it has to do sumtin with the reader ? Also I cant get it recognized on Vista: when i plugged it in for the first time, i saw some icons pop-up "Installing hardware...Finished" but couldnt get any other info. I cant even identify it in the Tool Manager.
I removed the cover, and took a look on it while it tries to boot up, the Reader slides over the disk, than jumps back, than tries to slide over it again than jumps back.....not what u expect from modern hardware :D (altough i never saw a working HDD without its cover).
Any1 knows any trick to discover the real problem ? or to fix it ? Got a pic of the cover with the HDD s specification, and a vid of the HDD trying to boot up, tell me if u wanna see it.
You damaged it by dropping it. What more do you need/want to know??????
"I removed the cover"
YOU REMOVED THE COVER OF THE HARD DRIVE?!?!?!?!?!?!
A hard drive is a hermetically sealed unit. The read/write heads travel over the platters by less than the thickness of a human hair. They are assembled in "clean rooms" that prevent dust from contaminating the platters.
If it didn't work before you removed the cover, it sure a s**t wasn't going to work AFTER you removed the cover.
If you did now you can't even return it under warranty.
Warranty was dead way before i opened it up - there was nothing to loose anyway ^^
Tx for the reply, now i can buy a new 1 without remorse.
And yea i know they re heremtically closed + they have a small package with hygroscopic fill that ensures dust- and vapor-free milieu(spent some of my time in labs with sophisticated stuff, im not that dumb ya know :) -rather curious).
And the 1 who should be freakin out is me(altough Im trying to save up my question marks), cuz whereever i go i hear "protection this and that, no dmg from falling..." and yet...well I see the opposite :/.
There's a difference between being dumb and "ignorant about how something works before taking it part".
As far as why it broke from a 20cm fall, look at the drive specs. it is warranted for x number of G's shock, which had a direct equation to dropped from how high". (I work for a hardware manufacturer)
BTW, AFAIK those drives come with a 3 or 5 year warranty.
Since your problem is resolved, I'm not going to do the research, but a 7" drop probably exceeds the shock rating for that drive.
Correct me if I'm wrong, but most shock resistant drives quit spinning when they've been dropped. Therefore, if the drive isn't plugged in and it can't be spinning. The shock rating pretty much goes out the window.
Shock
Operating Shock (Read) 30G, 2 ms
Non-operating Shock 250G, 2 ms
250G is a lot, and may or may not matter as to where the drive fell on (ex. corner, flat, butter side up, etc.)
My last bit of research on this as I was trying to equivocate 250G to "how far dies you HDD need to fall" led me to this article, which didn't really give a useful answer but was interesting reading.
