My 2 cents, FWIW.....
As others have said in this thread, for true write-protection (like
floppies provide) you will need hardware that provides that
capability. Such media is most likely aimed at corporate use, and
will probably be expensive unless you can find new "old" hardware.
Even then, how does it connect? i.e. instead of USB will you need
SCSI? eSATA?, etc.
My hope is that I can get a reader/writer that fits into a "bay" of the
desktop's case, just as on my old desktop the hard drive is mounted in a
case bays and connects to the motherboard via a cable (not via USB).
Connecting through USB, the USB will limit read/write speeds. I fear
you might be right about cost.
Without true write-protection you are mainly looking at methods that
are designed to protect you from yourself:
- mount file system read-only
- set modes on files/directories so that only root has access and then
avoid *reading* as root
- one I don't think I have seen mentioned - set the file attribute to
"immutable"
But any of the above will be defeated by simple actions such as
reformatting the drive.
I understand the first 2.
"immutable": do you mean "chmod 111 [file]" and "chmod 555 [file]", or
do you mean something else?
What are your requirements? Recovering deleted files? Protecting
against disk failure? Saving your data if your dwelling is destroyed
(fire/flood/earthquake/tornado/etc)?
* looking at old files; recovering older versions of files; recovering
deleted files
(I've very rarely needed these capabilities.)
* protecting personal data (not the OS and installed software) against
disk or desktop failure.
I don't currently have protection against fire and so on, but I
recognize I should.
My current focus is on the first 2.
2 cents?
No. Definitely more.
Thank-you.
