[Wylug-help] Readonly option in hdparm

[Thomas, Nicholas]

Hi,

Not really a linux question, but, Is it possible to make a hard disk drive
readonly?
I want to create a hard drive which cannot be re-formatted, or change any of
the data on any partitions.
I suppose I mean a read-only hard drive. It would be similar to having one
of those a TABs on a floppy diskettes.

I have been messing with the -r option to hdparm. This does appear to do
what I want, but the readonly status is lost after a reboot.

If this is not possible with a conventional hard drive, is it possible with
a compact flash card + IDE adaptor?

Any help appreciated.

Regards

Nick
