WD USB PCB SECURITY PROBLEM

[ibcho]

hi

i had wd usb pcb hard drive for data recovery WD10TMVW-11ZSMS1 model
hard drive works but very slow due to bad sectors or/and damaged heads
so i soldered sata interface to us pc3k to get full clone
pc3k sees drive fine with correct model number , serial and fw , like a normal sata drive
but, i cant get inside the hard drive . when i get inside it seems 4 partitions but nothing in there i can get the clone but still clone image has nothing as well.
so i guess must be a security problem , , itcould be security chip U8 chip faulty ?

any one has a solution or any idea please

thanks

More than likely, the USB part of the drive encrypts the data that is then sent to the rest of the drive. To access the data you need the USB bridge board too. Connecting a WD drive directly to the computer wont read the data.

Absolutely correct, the USB PCB encrypts the data through to the SATA.

Should he not be able to clone the encrypted data ?

yes but i unsoldered the capacitors С90, С91, С92, and С93 in order to
disconnect the USB bridge chip

As i can see, he's already done this.

Yes, you've bypassed the USB bridge chip now and are READING the sectors without the bridge, but the data has already been WRITTEN through the bridge chip and hence encrypted.

More than likely, the drive itself might be slow from overheating or like you said, bad sectors, so weather you connect it directly vis SATA or not, it will still be slow. Might as well restore the bridge connection and get what you can from the drive before you bin it.
