    Can SSD Password be recovered from BIOS bin?

    Recently a friend of mine bought in a Panasonic toughbook CF-54 with a locked BIOS. I was able to unlock the BIOS with the help of good samaritans here. After unlocking I realized that there was an SSD password. Before unlocking the BIOS, when I switch on the laptop, it would boot into a custom windows 8 with preloaded software without asking for any ssd password. Now I did not know the password and as it was urgent, I bought him a new ssd and sent him his way home. Now I have the old ssd with the password. (Attached the picture). I inserted this SSD into an old dell laptop and it prompted me for the SSD password which I do not know. The ssd does not have PSID to do a PSID revert. I also tried the HDPARM method but it failed. I have the copy of the locked BIOS bin with me (Attached the bin). Is it possible to retrieve the password from the BIOS bin? Is there any other method to unlock the drive? I don't need the data. I just want to make the drive usable again.

      What errors do you get when you try to use the hdparm method?
      Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

          although a password could be in the UEFI partition, it's more likely to be in the TPM eeprom

              SG_IO: bad/missing sense data

              I followed this guide - https://grok.lsu.edu/article.aspx?articleid=16716

              I am attaching pictures for reference. I tried this on a laptop as well as on a PC. Same error in both. Tried power cycling but it didn't work.

                      If you look at the next command, I corrected it. It still did not work.

                              I reproduced the steps in the following guides.

                              https://grok.lsu.edu/article.aspx?articleid=16716

                              https://ata.wiki.kernel.org/index.php/ATA_Secure_Erase

                              https://www.ibm.com/docs/en/linux-on...ion-sata-drive

                              I am still getting the same "SG_IO: bad or missing sense data" error

                              However, I also tried your recommendation now. It says "Missing PASSWD"

                              The HDPARM erase command requires a password it seems. That's why in all these guides there is a step to set the user password and then run the secure delete command using the user password. I am also attaching another image. Let me know if it helps.

                                  You have something similar to mine, which needed quite an effort to achieve

                                  Seeing your PM851 has no PSID on its label (a 32 character code I believe), PSID Revert isn't an option for you

                                  Although there may be faint hope if PM851 is Opal compliant:

                                  https://github.com/Drive-Trust-Allia...ki/PSID-Revert

                                  Failing that, based on my experience, you may need to get back the CF54, put the PM851 back in it, then go through a process similar to that required to unlock the CF54 BIOS
                                  better to keep quiet and be thought a fool, than to open your mouth and remove all doubt

                                      In some laptop models there's an hdd master password in one of the DXE drivers, 32-hex pair password, that is used as a recovery to secure erase the hdd.

                                          Unfortunately the drive is not OPAL compliant (refer attached picture). I did go through all your posts before posting this new thread. I have gotten in touch with my friend to see if he can hand over the toughbook for a few days so that I can try something with it. Will keep everyone posted once I get a hold on the laptop.

I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                                                  Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

                                                  Hello,

                                                  I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).

                                                  But today it's not accepting my password. I'm %100 sure i'm entering the correct password.

                                                  I'm trying to reset my bios without success.

                                                  I tried :

                                                  -I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries...

                                                  Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.

                                                  My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).

                                                  Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set....

                                                  1. I bought this laptop from flea market, and the seller said that he had never set a password, however here is a password required when pressing F2 to enter BIOS.
                                                  2. And after entering incorrrect password 3 times, there is no any useful information like "recovery code"
                                                  3. I used universal bios backup tool, and dumped 8MB bin file, but hex code after "SystemSupervisorPw" is...
