ok, lets say i do have head problems like some dr company i sent too the drive after trying the fix, said.
ok,

so, how come i had a dead unrecognized hdd and right after i finished the fix it was instantly recognized and i could see all files in dos.
when i conected the hd to a vista pc as secondary hdd it showed only d: and when i tried to copy d it stoped after 5-10 mins and wouldnt be recognized again.

something doesnt add up.

if i had bad heads, head crash, the fix shouldnt do anything.
if i had the firmware issue the fix should have lasted.
any ideas?

something i found later as i printed the output of the terminal
in the end when you get:
Max Wr Retries = 00, Max Rd Retries = 00, Max ECC T-Level = 14, Max Certify Rewrite Retries = 00C8

User Partition Format 10% complete, Zone 00, Pass 00, LBA 00004339, ErrCode 00000080, Elapsed Time 0 mins 05 secs <----- didnt get this line

User Partition Format Successful - Elapsed Time 0 mins 05 secs

i didnt get the middle line only the first and last, does it mean anything?

you might have some other problem besides firmware issue.
it happens very often, when drive has more than one problem.

How many threads are you going to make about this one problem?

Your disk had the firmware problem, likely triggered by other problems with the drive (in your case bad/failing heads). You were able to repair the firmware issue, but still were faced with the problem of bad/failing heads. After a bit of use the bad/failing heads triggered the firmware problem again.

you basicly took my question and formed it as an answer.

i am looking for somone who has expiriance to guess why doing a firmware fix (to the pcb) would revive completly a hard drive enough to copy from it for a short time and then be unrecognized again. if the heads where failing how come i could copy for 10 mins?
can a refix do it again?
what does your dr expiriance tell you.

mutiple problems causing the situation more complex. Weak/damaged heads with the damaged FW... You may do a quick FW fix but the damaged head will cause your drive from not coping data and back to the FW issue again.

Firmware has nothing to do with the PCB. You don't understand what is happening because you don't understand how your hard drive works. Do yourself a favor and read through some of the eleven billion old threads about this problem instead of making eleven billion new ones about your one case.

Dont try access to data in windows... make Data Copy with DE.
