Do you know if a command-line only version of atapwd exists ?
Do you know if an equivalent tool (ATA password settings) using the command line exist ?
Just to inform the community:
I searched Google and finally found the hdparm Linux tool which does exactly what I want and I also found a Win32 version of hdparm:
This is powerful (and dangerous) because it has many options and it allows setting a HDD ATA-3 security password from Windows.
The only problem is it need Windows loaded to work (it is based on Kernel32 and Ntdll)
Perhaps, the Linux version of hdparm associated with a minimal fast-booting Linux kernel could be added to UBCD : this is just a suggestion (perhaps it is already in UBCD even if I did not find it yet)
