Unlocking WD10EURX-63UY4Y0 - Master Password Rev 49047 - Sec

April 23rd, 2026, 14:51

Hello everyone. I don't care about the data, my files were already moved. Just needing to get it unlocked, wiped, nuked, whatever it needs to be usable again.

Drive Details:
​Model: WD10EURX-63UY4Y0
​Date: 12 OCT 2015
​DCM: HANNNT2CHB
​Master Password Revision Code: 49047
​Current Status (from hdparm -I):
​Security: supported, enabled
​Status: NOT frozen
​Security Level: High
​What I have tried:
I have attempted to perform an ATA Security Erase using hdparm via a Linux Live USB. I have tried the following master passwords (with correct 32-character padding/quotes):
​WDC WDC WDC WDC WDC WDC WDC WDC
​WDCWDCWDCWDCWDCWDCWDCWDCWDCWDCWD
​WDCWDCWDCWDCWDCWDCWDCWDCWDCWDCW
​32 'X's and 32 spaces.
​The Issue:
Every attempt returns: SG_IO: bad/missing sense data. The drive is definitely not frozen, but it rejects these standard WDC strings.
​Does anyone know if this specific revision (49047) uses a different Dell OEM master password or a specific factory string? Any guidance on how to bypass this lock for drive reuse would be greatly appreciated.
​Thanks in advance!

I have attached a photo of the drive label and the full hdparm -I output for reference.

Does anyone know if this specific revision (49047) uses a different Dell OEM master password or a specific factory string?

The master password has been changed by the person or device that hosted this HDD.
It's unlikely that anyone knows it. Contact someone with the necessary software (PC3000, MRT, wdmarvel?, etc).

I think the demo version of WDMarvel can unlock WD passwords, assuming that the Vendor Specific Commands are not locked out in this model. HDDSuperTool (freeware) also has a script for this purpose.
