Hi guys

I have Seagate U8 ST313021A 13Gbytes, the head is clicking, i eliminated the pcb problem.

Would it be better to remove the whole HGA and replace it, or just the preamp chip itself?

Thanks guys.

To replace the preamp U need to remove the MHA anyway. But it can be a good idea to replace it and have a good MHA if U don't have loads of this model on stock. This is not very frequent and hard to get these days, so U'd better be frugal on the parts
replacing the MHA is quicker though...

good point , I was thinking about the alignment issues, thats why i was thinking to replace the preamp only, but then again the preamp chip is very hard to reach and remove either using hot airgun which will melt the plastic ribbon cable or too awkward to work under tiny spaces. thanks pepe I think i will just replace the whole MHA.
