Hard Drive Recovery Solution
The Story: My hard disk DeskStar Model HDT22516DLAT80 with Formatted
Mac has stopped to run. Because BIOS hasn’t detected the hard drive
and it was not warm I appreciated that the logic board is failed. I have
bought a refurbished hard disk identically (same model, FRU, MLC, LBA
and same CHS naturally). I replaced the logic board of my old hard disk
with the board of the refurbished hard disk. Now I seeing the old hard
disk is warm (normally, not hot) I hear the head to Power ON and I feel
the disk are spinning, but the BIOS does not detect the hard disk.
Your data now seems LOST !!!
- step 1:
Locate an identical Hitachi hard drive model HDT22516DLAT80 for parts.
- step 2: Swap
the PCB Controller. If the drive is not recognized
by the computer,
- you will need to swap the U7 flash memory chip M25P05 (512 Kbit, Low Voltage, Serial Flash Memory).
- this chip is usually still good even though the PCB Controller is
fried.
- The chip is only 8 pins and should be easy enough to replace. It contains
the Boot Program for the hard drive.
- Be careful with this chip, if you break it, you're screwed.
- step 3:
NOTE: I like HDCLONE
from Data Recovery Labs, it works well for cloning hard drives with
bad sectors
- step 4:
Once you have cloned as much of the drive as possible, you should be
able to retrieve your data.
-Making a second clone is more effort but will protect your data should
something go wrong during the Recovery process.
-Note: don't forget to restore the jumpers back for correct Master and
Slave functionality.
