Locked drive accessible in other PC but not on laptop it was locked on

As stated in earlier posts, I have an Acer Brick, series e1-531.

BIOS detects the drive but still considers it 'frozen'.

I have tried entering the 'master' password of 32 spaces; the end result is the laptop will attempt to boot Windows - WITHOUT prompting for a HDD password.

Booting in Safe Mode reveals that Windows is getting to disk.sys, BSOD, then reboot.

I can force the laptop to boot from a Win7 DVD by hotplugging the HDD in after BIOS initialisation, however the HDD is then not detected by the installation software. I have hotplugged the HDD into a different PC, which resulted in me being able to access the drive and both partitions without prompting for passwords.
