hd not clicking

[positivebit]

when a hard drive, after falling down, is not clicking, but not recognized,even from HD doctor, what can be?

That most probably heads and / or SA are gone and / or SA is not correctly accessible AND/OR there is mechanical problem (= a class of problems). Simple

sorry for my update, but after i left the HD attached to the doctor and i "forgot him" there for a long while, it became now ready i made this task:


Fail to read nvram, rom is ok.

fw: i can see the modules, but i can read only 6 of them (wrt 0 to 5).
Glist: i can't read: fail to read RDMT

any suggestion will appreciate.

hi,
is it an italian 3ad?

ok so you are talking of a HITACHI drive .. can you tell us the model?
if is not an ATCS sounds strange (to me) you can't read NVRAM but you access SA...
no B copy of modules is readable?
Give us some further informations in order to help you

hi,
ok so you are talking of a HITACHI drive .. can you tell us the model?

The model is HDT721075SLA380
* UPDATE the hard drive is not falled down, in the last times was difficoult to recognized him, and than it became not responsive ( ina normal pc..not in HD doctor)

for the question " no B copy of modules is readable? " i must admit that i do not understand ..

so i switched into safe mode, downloaded SA-C modules, but there were only few availeble.nothing to do.
But, i noticed that SA-B is perfect. i selected that one and i can see many sectors. sometimes the hard drive is very slowly.
the P-list have about 80.000 values.
i connected to data compass , emulation SA, HD detection, i can recognize it, open up a shadow disk and now i am trying to scan partition.
it will take about 24 hours becouse it is reading very slowly and it is big (750GB)

any suggestion ?

Don't use shadow disk you will be sorry. In your case the drive has more than likely some damage from being dropped. If you can clone it as you say it is better to try and do it straight off with creating task then cloning it. Forget this shadow disk. You should try and open this up in clean room and check your platters for damage due to the drop, examine your heads, and spindle motor. Make sure your platters are not out of alignment. Do not force this to clone that would be a mistake on your part. If you can clone it go to task manager and ceate a task and clone it from there do not waste your time with shadow disk.
