Had one last week with exactly the same symptom. 2 of the heads were dying, required headswap in my case.

Thanks for your reply Mr.Nick_CT,
I will try to search for a donor to perform a headswap (It's very difficult here in Egypt to find a donor for those hitachi's)

I appreciate your reply.

After replacing 4heads the drive make the same thing.
The problem must be ELSEWHERE.

Any suggestions ?

Put the heads back into the donor, do they still work?
Maybe you have some media damage.

Hello Mr.Nick_CT,
I have moved the patient's heads to the donor and it working. So the problem not heads.
I believe now that the problem not head/s or preamp. It must be FW, but I don't have the proper tool to access the SA for those new hitachis.
