Salam to All Experts
the thing is that there is no recognizable drive. I used the Data Lifeguard Diagnostic, downloaded from the WD website. The results I get are as follows:

Drive # : 2
Model Number: WD My Passport 0748 (USB)
Serial Number: WXD1xxxxxxx (I've omitted the serial number here)
Capacity: 0 MB
SMART Status: Not Available

The drive passed the Quick Test and the Extended Test (the capacity shown is still 0.00 GB), but the drive failed the Write Zeros test, giving an error code 20 [delete partitions error!].

I don't care about the date only just want back 1tb hdd in working condition
