Data Recovery Solution
Following steps were performed for this case:
- Short connect: since it is unable to read the ROM and module, user need to short connect the TV9 and TV10 on PCB. Release this operation once the drive get ready.
- Back up ROM and read firmware modules: this is a simple but important steps for all WD cases.
- Bypass SA
- Slow fix: go to common repair – slow fix. This is a very useful feature for WD drives. Many cases like slow initialization, slow detection and slow reading can be fixed by just this one click.
- Check modules: check all modules to see if there is any other firmware module damage. If no other firmware damage, firmware restart and wait until the drive gets ready.
- Scan the drive: ID information was detected, the whole drive can be scanned smoothly.
- Data extraction: use DDP file extractor to check the data, all the files are accessible and all files are recovered
