Yes.

It's very easy to enable/disable SED to gain SA access.

The problem would be to decrypt the data...

If the drive have some FW issues you might disable SED, fix firmware and re-enable SED. This can be done even on RAM by patching config (module 02).

But if you can't fix the firmware or if you can't gain access to the UA (LBA) with original PCB and SED turned back on then you might have problems as the data would be encrypted ....

This is strange. Either SA access is locked and you can't access ANY module or SA access is not locked and you can access all modules.

Are you sure the SA is ok ?

yes ican access the sa in diagnosis mode but i can't edit 32 because of sed.
if i pass sed and apply slow responding and put sed back i can decrypt the disk by mrt.

Ok.

If you read 02 in RAM and if you patch 02 in RAM you can disable SED.

MRT should be able to do the job ....

Contact tech support ?

You can try with WDMarvel DEMO version. If you can read RAM with it and check config on RAM then most likely you can disable SED. Problem will be decrypt the data.

hi spildit the problem solved by pc3k.
and you were right it was not a sedlock drive it was a mrt weakness.after the drive com ready when click auto the drive goes to busy and mrt can't handle this situation but with pc3k it was very simple.

MRT tool for WD is ... Junk.

You should try WDMarvel one day. It's really good. And of course SeDiv is very powerfull as well.

Ok.

If you read 02 in RAM and if you patch 02 in RAM you can disable SED.


And the drive full model is ?

Did you try to gain SA access ? Can you read/write module 02 ? Do you have access to modules ?

I ask this question generally, is there any straight method to disable sed or its different from drive to drive?
what is mean of patching mod 02 ?

yes you can do it by mrt know but first you have to short tv9 and tv10 point in pcb or use a visit card and then when you get the id go in kernel mode and from the rom menu disable mod 411 and turn of/on the harddisk.
after this you can access the sa in all mode you can solve slow responding and edit mode32 and change 01 to 00 in mode 02(the location its different in families)but when you read the post mentioned above you can find out the location.
and after edit don't forget enable (sed and mod411) you need the sed for decryption.
good luck

Create a DE task, do a headmap and disable the weak head.
