How to un freeze drive in Linux?
I run
sudo hdparm -I /dev/sda
results:
Security:
Master password revision code = [redacted just in case it's sensitive data]
supported
not enabled
not locked
frozen
not expired: security count
supported: enhanced erase
My objective is to perform an enhanced secure erase (how? I'll find that out after I know how to unfreeze my drive) and also to detect and remove a Device Configuration Overlay. Relevant thread: Error when running 'hdparm --dco-identify' in Linux
I am trying to figure out why --dco-identify is failing and I suspect it may be as a result of the drive being "frozen". I recall this being a problem a year back when I was trying to securely erase an SSD. I gave up but suspected that connecting it via USB or hotswapping it might fix it.
Why? Refer to:
https://ubuntuforums.org/showthread.php?t=1982585
So in the context of this post, I am trying to unfreeze my drive. How can I do this while it's connected via SATA?
Update:
I tried this with an external HDD and ran
sudo hdparm -I /dev/sda
The drive is not frozen. Fascinating.
I ran:
sudo hdparm --dco-identify /dev/sdc
The command executed successfully!!
So that's confirmed but still does not answer my question about whether this can be achieved with an internal drive

Success!! I managed to unfreeze my drive by making the SATA port it is connected to hot-swappable. This involved me going into my BIOS. How you can achieve this will vary depending on your BIOS manufacturer.
Once the SATA port was hot-swappable, I did the following:
1) turned pc off
2) disconnected the SATA data cable from my motherboard. Left power cable connected.
3) turned PC on and booted into Linux
4) Connected HDD and Viola! It was unfrozen and "sudo hdparm --dco-identify /dev/sdb" was working!
5) I checked to confirm it was unfrozen by running "sudo hdparm -I /dev/sdb"
Note: device is at sdb now and not sda (as you will find in my other thread - linked above) because the HDD was connected after Linux was booted into!

If you cannot make your drive hot-swappable, you will have to buy a SATA-USB cable and connect your drive via USB.
