Hi waqs was recently trying to get a pc working again and stupidly used my main HDD, for some reason at one point once re-connecting the HDD, I had a small amount of smoke and a fizzle noise from around the circuit board. I have just remove the circuit board and there appears to be no burn or obvious damage to it.
There is a chip set underneath and I don't want to just remove it without knowing what it does, as I would love to recover the HDD.
Any idea if this could be my problem and how and where can i get the chipset and replace it ?
Your hoping !
However, since there is only one manufacturer of hard drives, and since this single manufacturer only makes one model, then we don't need ANY more information than what you have provided.
So yes, go ahead and replace the "chip set". Your local RadioShack should have it. BTW, you won't even need to show them your hard drive. They will IMMEDIATELY know EXACTLY what your are talking about.
Seriously though, let's see a photo of the component side of the PCB. Sometimes there is an easy, no-cost DIY repair.
We tried to test those and my guy who is an engineer and knows a bit a pcb's said it hard to test them accuratley on the board and we didn't really get a conclusive result, I am going to try and buy another PCB, as it turns out on closer inspection there is a scorch mark next to the 5volt TVS
I will be in touch with results and thanks for all your help so far.
AIUI, a straight board swap usually won't work. The board has an 8-pin NVRAM chip that must be transferred from patient to donor. This chip stores unique, drive specific "adaptive" information. Also, some in the data recovery profession are of the opinion that using a board with non-native adaptives can cause the drive to overwrite these data.
