i did something kind of stupid.
i pluged in a new power supply on a computer i was working on and fried the mother board, to test out the power supply i hooked it up to another computer (this is what i get for being lazy) and the power supply blew up the mother board and fried the hard drive.

i have tried plugging in the hard drive in to two other computers and they wont even start with the hard drive plugged in.

I would say its save to say the hard drive is fried, but i was wondering if it would be passable to replace the PCB on the hard drive and pull some information off of it.

the drive is an:
Seagate 160GB IDE
Berracuda 7200.7
Model: ST3160021A
S/N: 3JS2LVXC
HDA P/N: 100307104
CONFIG LEVEL: 9F0M1
CONFIG CODE: D1H-02
FIRMWARE: 3.06

Possible, just maybe. First, recognize that you are presuming the problem is in the PCB on the HDD, and not elsewhere. Probably better than a 50% chance, but not guaranteed.

Then you need to know that you almost have to get the exact same PCB. I've seen lots of posts about doing this and running into failure because, although the HDD model number and specs never changed, the HDD maker updated the design by using a different PCB. Then someone tried the swap approach and the different PCB would not revive the failed drive. So if you go ahead, look very carefully at all the markings on the PCB and the details of HDD model numbering. You need to identify something like a "Revision Number" on the PCB and get another just like it.

Good luck!

Ssd raid 0 poor benchmarks
By sub mesa, 8 hours ago:

Expensive hardware RAID for a simple RAID0 array? LOL! Dont waste your money please. Even the most expensive hardware RAID are slower than software RAID when it comes to random IOps benchmarks; Areca ARC-12xx seems limited to 70.000 IOps. There can be several reasons your RAID0 is not functioning properly: - you have a 'bad' partition (misaligned) starting at 31.5KiB offset - you have multiple partitions on the RAID; and the second partition is not properly aligned - the selected stripesize is too low (< 128KiB) - you defragmented your SSD at least once during its lifetime (you need a full zero write to regain performance) - you performed inadequate benchmarking (low queue depth) If you want some serious advice and really solve this issue, you must do some work yourself: - explain your setup in more detail (enabled the 'write caching' option in Intel drivers? How did you create the partitions? Can you check for the partition offset, etc) - post proper benchmarks performed at the filesystem level, for example HDTune Pro's "File" benchmark. The normal HDTune benchmark only tests raw disk access; without using read-ahead which your filesystem does use to allow parallel I/O processing. If you can do that, i might be able to help you out with some specific advice.
