testdisk Trying alternate GPT and i/o error

#1 Post by ewas » 12 Feb 2015, 14:35

hi all,

i'm under mac osx 10.6.8.

i've an TOSHIBA MK2555GSXF - 250 GB HDD.
a friend of mine spilled tea over the macbook. i removed the hdd and put it in an external drive.
motor doesn't spin. changed the hdd circuit board - no spin. opend the disk - head was stuck - position the head back while truning the platter current clock wise.

now the disk is spinning and will be recognized by testdisk and even disk util.

after choosing efi/gpt partition testdisk searches without any success.

tried fsck:

CANNOT READ: BLK 16

the testdisk log file will expand endlessly with i/o errors... here is what i got:

All read operations failed, it's a physical problem, probably a damaged head. Only a data recovery company can deal with it. Software can't help, the head has to be replaced.
