In this data recovery case study we’ll be working on a Western Digital hard drive model WD500KS-00MNB0 pulled from a My Book external enclosure. Hard drive has failed read/write heads and require clean room work.
Initial Hard Drive Information
Date: 29 AUG 2006
Country: MalaysiaDrive spins up, does not click but shows as unrecognized to computer when USB connected.
Data Recovery Diagnostic Phase
Drive connected to PC-3000 and powered on. Reaches ready state, but in Kernel mode.
Backup of service area, ROM, and service tracks made. Attempted to set max LBA and hotstart drive (unsuccessfuly)
Contacts on donor PCB noticed to be extremely charred. Contacts cleaned (no effect)
Donor PCB pulled from stock and ROM programmed with donor ROM code. (no effect)
Attempted to change headmap in ROM to determine which heads have failed (still only has access in kernel mode – seems to be a Zeus family issue).
Compatible smart hotswap donor not available in stock, order one for stock to load tracks onto PCB.
Customer quoted $700 labor cost plus ~$100 for donor parts (approved)
