Difficult to say about "how long", reports vary, and may be not entirely reliable.

 

Check if your PCB is the same as one of those whose images were posted here:

http://forum.hddguru...=18907&start=20

If not read ATTENTIVELY this thread:

http://www.msfn.org/...1-nor-a-720012/

and/or post pictures of BOTH sides of the PCB.

If you are positive about having identified the "read channel" (and two corresponding points on the upper side of the PCB to be shorted), you might be shorting them "at the "wrong" time.

At least here (for the 7200.11 ES2 drive):

http://www.msfn.org/...000000cc-state/

the shorting had to take place after you get the connection and the F3 T> prompt and before you get the "LED:000000CC..." message.

(and it is seemingly very difficult to get the right timing, or at least everyone had to make several attempts to succeed).

BUT, do you get the terminal prompt pressing CTRL+z?

Does the disk actually spin up?

 

The "ZZZZMMMMMMMMMMMMMMMZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ ..." seem like an issue with connection (grounding/adapter/etc.). :unsure:

 

IF you are having *anything* different from the LED:000000CC" error (that presumably can be worked around by shorting the read channel), WHAT made you think that you needed t short the read channel? :w00t:

 

I mean, it is entirely possible that you are applying the right cure to the wrong disease or the wrong cure for the right disease. :ph34r:

i can just see.  sometimes showns in bios but capacity is 3-4 gb and it has different model name.

disk spins up. clicks 4-5 time (after every clicks , prints" [0x00000000][0x00000000]ZZZZMMMMMMMMMMMMMMMZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ

ZZZZZZZMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMddddddWWWWMMMMMMx" )
Then head stops , after few minutes it shows LED : 0000000EE

I believe that the 3/4 Gb capacity (+different model name) is an altogether different issue from the ones (BSY and/or LBA0) that can (hopefully) be solved by the known procedures here.

 

See if any of the good guys here:

http://malthus.zapto.org/index.php?

 

can help you, but please, try not to fall (again) in the XY issue:

http://homepage.ntlw...red-banana.html

just provide the most info and as wide as you can description of the issue you are having (as opposed to asking help about how to perform a specific procedure that is not appropriate):

i have asked hdd oracle and hddguru forums but no answers  :ph34r:

seems to be st3500418as disks are closed for any terminal operations  :thumbdown  . 

somebody says that wrong model name and capacity problem can solved with same solution of bsy and 0 lba problems. main problem is i cant enter any commands from terminal  :no:

data is not important actually. but i was want to make some experience points for my hdd information  :w00t:

thanks for your helps.
