Hi, my first post

I was looking for information on my hard drive, and stumbled upon this forum, and decided to ask for the help of those who know.

I've been working on IT for a few year's, but i'm unable to diagnose what is wrong with a hard drive once it fail's, so here i am, asking for your help.


This drive was on an external case, Iomega, connected to my home server with a usb cable. Last night i was changing some stuff around the server and accidentally touched the power cable, it made that electrical sound, but the server went on with it's business, but the external casing of the hard disk disconnected, to never work again, i guess something was burnt.

I dissassembled the hard drive from the external casing, to plug it directly in the server board, on the first time it recognized the hard disk, when i realized i only had 1 sata connector, occupied by the server's boot disk. Turned it all off, went to the local store, got myself a new sata cable, but when i turned it on i slightly touched the server chassie with the hard drive. From then on the hard drive spins up, but the server won't recognize it, and it keeps making a weird noise. It loops around and around, never stoping.

Here's the video.

The PCB seems ok, i see nothing burned, but that's not a fact. I'm willing to spend a few euros on a PCB to recover the data!

Any expert advice?

Is it mechanical? Is it the PCB?

Thank you for any input

No need to do all that, terminal will 99% say...

Either the PCB is bad (less likely) or the head/preamp is bad (more likely).

If you have another PCB that will fit (not necessarily the same version), try it. If the noise stays the same then its the heads/preamp in which case you need pro help for sure.

Olá de Portugal Obrigado pelo esquema, mas eu não compreendo nada de electrónica. Isso não se vende? Acho que vou arriscar a compra de um PCB e trocar


I found a video on Youtube and the sound is EXACTLY the same until 1:06. My disk keeps doing the noise for a few mins (2, 3 tops) and then completly stops. Let's see if it help's. The platter's are spinning, it's a 7200 rpm drive, i can feel it and the place where the drive is sitting knows it too, it makes a lot of noise due to the vibrations.

Thanks for the quick reply's. There's not much data i really need on the disk, only 2 songs i wrote, one of them is already signed on a INDIE label. Not much money (i guess i won't even make any with the song), only hard work and time i invested on them
