Panasonic Toughbook HDDs with hard drive encryption - how to reuse them?

[jasakl]

Dear community,

i have searched the internet but i dont found a working solution for my problem:
I have about 150 hard drives (mostely from hitachi 160gb HTS543216L9SA00) from Pansasonic CF-19 MK3 Notebooks.
All devices had a BIOS Password and HDD encryption enabled.

Now i try to reuse the HDDs, but i cant format them. I already tried windows Diskpart with argument "attributes disk clear readonly" but it says "cant delete" and i tryed several partition and low level formatters (like partition wizard, AOMEI and Easus).
But all of them cant create a partition table / format it.
I also tried to clean it with acronis, but it says disk error/cant read.
And i tryed a HP 2560p bios feature to erase the disks. It says the feature is not available because the drive is locked

All disks are in good condition and work in their own original divice.
Crystal disk info also say good condition.

Does anyone have a good idea to format them.
I dont need the stored data on them.

Disk encryption also work on ssds from several vendors, so i think it is not a model or vendor problem.

Thank you for your help.
