Oldest Linux Kernel supported? How to unlock WD on Linux 2.6?

[jittygitty]

Its working for me on newer kernels just fine, but same drive in Linux with kernel 2.6 etc simply won't work, see:
SofianeHamlaoui/WD-Decrypte#9

sg_raw Error is: "Fixed format, current; Sense key: Illegal Request Additional sense: Invalid command operation code"

Seems it is not seeing the WD SES "enclosure" which does the security and so I end up trying send sg_raw to disk itself ie Type 0 instead of WD SES enclosure which is
"Type 13" and so the c1 e1 00 00 00 00 00 00 28 00 is rejected by the disk/Type-0.

I might be onto something after some more digging on why WD SES isn't seen.

Would appreciate if any (@DanLukes @KenMacD @arno01 @electronicsguy ) in the thread at #19
Might give a read to this and throw me any pointers.
