HDD GURU FORUMS

Jonny, the script you are using is for older WDC chipset drives, and your drive has a Marvell chipset.

Thanks again. Wow, 2 good responses in one day ! I should go buy a lottery ticket.

Okay, so is there a script for a Marvell chipset ?

Yeah read this thread unlocking-ata-password-for-western-digital-t8374.html

I've taken up this project again. I still have the two WD800JD's.

I've made a floppy diskette, added the USB driver to the config.sys file, booted to the floppy, the HD mounted in an external USB caddy and is recognized by MHDD as

6. HDD: Generic External (NOT READY)

I use this script:

; rm modul id 42
reset
waitnbsy
regs = $57 $44 $43 $00 $00 $a0 $8a
waitnbsy
regs = $00 $02 $00 $00 $0F $E0 $21
waitnbsy
checkdrq
sectorsto = 42.bin
; End.

It fails at

Line 1: RESET
Please switch to IDE mode before using this function.

The desktop computer I am using is a Dell 2350. I upgraded the BIOS from A0 to the most-recent A2, and there are no BIOS commands that set anything to "IDE mode", and I cannot find anything in MHDD that allows you do switch to an IDE Mode either.

What do I do next?

Hi,
I can suggest a different approach.
You might be able to input a valid master password using the Dell service tag from your 2350. Dell support also offer this service at a cost providing you can supply proof of ownership. The master password will reset both bios and hdd passwords if the hdd password had been originally set by the Dell bios security function.
I'm not going to describe this in any great detail on this forum but Google would be your friend.

Sorry but forget what I suggested earlier as your 2350 is not the original pc the drives were removed from. Anyway perhaps the original model does not have the hard drive security option to set a password in this manner.

hi there bro i have the same problem with a HDD trying to unlock it ... i got the same NO DRQ response from the script ... did you by any chance make some progress
