Who shows up as the owner of these files when you copy them back to the
hard disk? If it is you, or someone that you have the password for,
including root (assuming that you have root access) then why not just do a
chmod on the files that you want to change once you've copied them to the
hard disk? If you own the file just do a chmod 644 to give the owner read
and write access and read only access to group and world. You can do it
with r and w arguments, but I use the numeric codes myself and I would have
to look up the others (try man chmod).
The numeric codes are a 3 digit octal number: where each digit is made by
combining read = 4, write = 2 and execute = 1. To get read/right
permissions but not execute the digit is 6 (4 + 2) read-only is 4, read and
execute is 5 (4 + 1) and read/write/execute is 7 (4 + 2 + 1)
The three digits stand for owner, group, and world permissions.
If your linux hard drive is 40 Mb it will fit on a DVD and can be copied
using xcdroast. If it is 40 GB you'll either need another hard drive or a
good-size tape drive. You can use something simple like tar to copy the
files over or Arkeia for a more complete solution.
To fit 40 Gb on a tape you'll need something like an AIT-2
