I have several files that I need and they are in read-only mode. They're on a floppy and I can't copy them because of the read-only and I'm unable to uncheck the box. Is there a way to uncheck the boxes?

You should be able to copy them to the hard drive, edit them then copy back to floppy

That's unusual and happens more if you try to move them as opposed to copy them

Is the floppy write protected

This is the reason, apparently

TITLE : Howto make a read only filesystem on a floppy diskette.
OS LEVEL : AIX
DATE : 17/01/99
VERSION : 1.0

----------------------------------------------------------------------------

You can build a filesystem on a floppy and mount it, however the
filesystem will be read only. The reason that the filesystem will be
read only is because AIX cannot create a journal log on a diskette.
The intended use is for temporary access to read only data. The
diskette file system must be unmounted after use and during system
backup procedures or errors could occur.

To make the read only filesystem on a floppy:

1. Make a subdirectory on an existing filesystem and place all of the
files that the diskette will contain into this subdirectory.

2. Enter the following command to create a prototype file containing
information about the new filesystem, in the example /dir_struct
is the pathname of the subdirectory created in step 1, and
proto_filename is the name of the prototype file to be created.

proto /dir_struct > proto_filename

3. Place a formatted floppy into the drive.

4. Edit the prototype file and replace the first line with the following:

<noboot> 0 0

5. Enter the following command to make the filesystem on your floppy:

mkfs -p proto_filename -V jfs /dev/fd0

6. Create the directory upon which you will mount the floppy based
filesystem, or you can use /mnt. Mount the filesystem:

mount -r -V jfs /dev/fd0 /your_mount_point

7. To unmount the filesystem:

umount /dev/fd0


This will be of use if you create floppies from now on. I will look for an attribute changer
