Erase/decrypt a Toshiba KHK6XLSE SSD

[quark]

Have some of those drives decomisioned from servers, which I have not access anymore. They are TPM/hardware encrypted and not accesible, is there a way to erase/unencrypt them to be able to use them again? thanks

Do they support PSID Revert?

I cannot see at the label anything related to the PSID... here a photo from the label:


and the "datasheet"

Did you try secure erase standard and extended through hdparm, with known master/user password set before by the same hdparm? Also Toshiba has its own ssd monitoring utility with secure erase option.

Yes, tried before posting to change password and the output is an i/o error



The thing is that it isn't frozen and enhaced erase is possible (it says)



Didn't find the tool for toshiba ssd drives, does it work with enterprise ssds?

Try to set USER password, with "--user-master m" , an after that try to set "--user-master u" or just start erase as user or master with seted password, if disk allowed to set it. I have the same with HK4 it wouldnt accept user, but accept master, and after that accept erase. Try to add "--security-mode m" or "--security-mode h" then trying to set it.

Also you can try default master password --user-master m and 32 spaces ass PWD.

As toshiba tool you may try KIOXIA SSd Utility. https://europe.kioxia.com/en-europe/per ... ducts.html storage utility , legacy ssd utility.

Also try PSID-Master password as "12345678901234567890123456789012"

Thanks a lot for your answers.

Also try PSID-Master password as "12345678901234567890123456789012"

Do you mean with sedutil? used --scan with it and the drive isn't Opal compilant

Could you elaborate a little more? I am pretty new about hdparm

Tried different kioxia utils without luck. I'm going to try contacting kioxia/toshiba...

No its not opal drive, so it was mistake, not as PSID ,but as Master password with hdparm, 1234567890... or 32 spaces. As for hdparm, you tried to set User password with "--user-master u" option, does you tried to set Master password with "--user-master m"? Sometimes disk allow to set master password, when user password is enabled. Also when you trying to erase it, you must specify the type of password with "--user-master" m or u.

Pitifully nor m nor u let me change the password, I will try today with the "12345678901234567890123456789012" password

Thanks again.
