My Knee jerk reaction when a computer tells me the HDD is “Write protected” is to assume that the HDD is encrypted as some corporations do…
At that point I set the HDD aside and try installing the OS on another HDD.
Until recently I had a stack of Hitachi/IBM drives that reported similar errors
and when any of them were connected to a computer via a USB housing they
report as “access denied”
I say “until recently” because they all went into the trash early last month.
they are someone else’s problem now.
Replace the drive and try again.
Look at the bright side… it doesn’t appear to have a BIOS password you need to bypass…
I suggest you get an OS installed on another HDD THEN try to update the Bios
