Sorry my first post is one asking for help.

Here is the situation:

I have a neighbor's HP PC which the system restore files are on a 5GB hidden partition (HDA1, NTFS).

I want to reinstall his OS (Win XP home) on the already formatted C:\ (HDA2) after I can recover the files from the hidden partition.

I have temporarily placed a 2nd hard drive in the machine to copy the 4GB of system restore files from HDA1 to HDB5 (the 2nd hard drive, FAT32).

I am running Knoppix Live from the CD.

I opened the console and typed su to logon as root.

Typed the following command to copy all files and folders from HDA1 to HDB5:
cp -R/mnt/hda1/* /mnt/hdb5/

this is what was returned to me:

cp: cannot create regular file '/mnt/hdb5/insert filename here' : Read-only file system

How can I change the permissions so that I can copy all the files from the hidden partition to the 2nd hard drive, WITHOUT destroying the files on the hidden partiton?

and

Is there a simple way to restore the permissions to original after the copy (if the permissions are changed)?

thank you for any help you can provide.
