sudo hdparm --user-master m --security-set-pass NULL /dev/sdb
sudo hdparm --user-master u --security-set-pass NULL /dev/sdb
sudo hdparm --security-disable NULL /dev/sdb
sudo hdparm --security-freeze /dev/sdb

В итоге стало так:

Security: 
        Master password revision code = 1
                supported
        not     enabled
        not     locked
                frozen
        not     expired: security count
                supported: enhanced erase

Однако, после выключения/включения диск опять залочился.

А помогла замена суперконденсатора,а после этого Secure Erase с помощью OCZToolbox.

https://www.eevblog.com/forum/repair/ocz-vertex-2-ssd-firmware/ In order to fix the Vertex 2 when not recognized by the BIOS, you will need the manufacturing tool called mp_tool by Sandforce together with the license file *.lic and the firmware package file *.dst. All of these are posted in a site in China so use baidu.com to search for it. The mp_tool is included in an image of 1.2GB or so which you will need to write to a USB drive and boot from the USB drive. The site that posts the tool included the instruction so follow it.

As far as the Vertex 2 SSD goes, you will need to connect P8 and P9 (the two copper pads in the back of the PCB) when powering it up to force it into manufacturing mode to allow the mp_tool to talk to it via the SATA cable. So jump those two pads, connect the power cable and after a few second disconnect the two pads because when the mp_tool talks to the drive, at some point in time it will reboot the drive and you don't want to force it into manufacturing mode at that time.

If your drive configuration is not included in the *.lic file, it gets much harder because you will have to modify the mp_tool itself to overwrite things, which I am not going into details beside the fact that the tool is written in python script and you should be able to decompile it and modify the script as you like.

As far as the serial port goes, there is a tool called ecli.exe that will decode the output and display something readable, which might be useful when the mp_tool fail, you could find out why it fail from the serial output.

If you plan on using these SSDs with the Sandforce SF-1200 series controller, it is a good idea to download these tools now and save them somewhere for later since they will probably won't be available forever. The links below are completely DOWNLOAD AT YOUR OWN RISK!!!! I recommend using a junk computer for all of these activities since the files are from China so please be very careful using them.

Link to mptool, firmware, and license file download:

(Use Tampermonkey browser add-on to download if you don't have a baidu account. You could copy the link generated by the add-on and use a download manager to connect as many connection as you can at the same time because a connection is normally slow and timeout very quickly before you could download much at all.)

Russian forum where I got the link above from, it also got the link to the instruction: http://forum.ru-board.com/topic.cgi?forum=84&topic=4797&start=0&limit=1&m=6#1

Here is the link to the eCLI application used for SF-2000 series, but seem to work fine with SF-1200 series:
