Use the search function for "nv-ram". It will help you understand why the PCB swap is not enough as a fix, given it is a PCB issue.

In order to get a little more helpful advice, you need to provide more details about the drive's behavior after power-on.

Does it spin? If yes, does it click? Etc.

For comparison, you can listen to other drive you have to hear what a good drive should run like.

1) put PCBs back to their own drives
2) power-on the healthy drive and listen to how it operates (ex: begins to spin, then hear two-three quick clicks, still spinning, then drive shows up in device manager)
3) Do the same with failed drive. Then post here the drive's behavior by referencing the example above.

When having on original PCB does the drive show up in your BIOS. You say it takes a long time to boot with this HDD on it.

BTW board swap like you try will not work. Hitachi has adaptive parameters in the NVRAM that have to be moved over to work. You can not simply swap out a board and it will work. You either need to move the NVRAM to the donor drive board or have special tools to write the NVRAM to the donor board to make it work

@ labtech i am at work right now and will check it once i be home and post it here

@ poehere yeah it takes longer to boot up and the drive doesnot show up in BIOS so how can i get those special tools to write NVRAM to donor drive board and another thing is will i be able to write back the NVRAM of the donor drive to donor board.

"Almost" means there is a difference. What is that difference?
Last last time I will try to help in this case if you refuse to be descriptive.

Search on MHDD and see if it detects the drive

The have more severe problems. Sending to a pro is the best course of action if data is important.
If not, try RMA.

That can mean one of two things. Either:

a) Your "problem" drive has a serious issue; or/and
b) Your motherboard & BIOS is not configured (or not able to be configured) and being used by you, in a way that makes it compatible with MHDD - so even a good drive wouldn't be detected by MHDD in that case, and that can mislead any attempt at diagnosing the "problem" drive too.

I've replied to several similar situations in the past. Search for MHDD in my previous postings using the forum search feature, to read those discussions (e.g. SATA controller setting, SATA port used etc.).

To distinguish between options (a) & (b) above, it can be simplest to attach a known-working drive to the same SATA port where you plan to attach your "problem" drive, and check whether that known-working drive can be detected by MHDD. If that known-working drive can be detected and responds to EID correctly, then point (a) above is likely; if not then point (b) above is likely and you need to resolve that first, before you can then use MHDD as previously suggested by labtech, with your "problem" drive.
