Thank you... still getting "Permission denied" even after doing the chmod and then the chown commands.

Possibly related: I discovered that I could right-click on the mprime icon to get the Properties, but when I put a check mark next to "Allow executing file as program," the check mark disappears right away.

I'm wondering if I need to actually install Zorin OS on some kind of drive before any of this works. (Currently running it on a live DVD -- not a CD as I wrote before.)

Rodrigo

EDIT: I wrote that and then EdH's post appeared after I submitted mine.

Can you do

ls -l

from within the mprime directory on your usb thumbdrive and post the output here?

Also, please post the output of

cat /etc/mtab

Also make sure you are running 32-bit software (e.g. mprime) if it is a 32-bit operating system, and 64-bit software (e.g. mprime) if it is a 64-bit operating system.

[Rodrigo]

OK, I'll do that as soon as I figure out how to redirect the terminal output to a file. I knew how to do that in MS-DOS. It'll be another opportunity to learn my way around Linux.

I can confirm, though, that it's mprime 64-bit and Zorin OS x64.

To redirect standard output, append the command with "> your_file_here" e.g.

ls -l > ls_output

While you are at it, please run

ls -l .. > ls_parent

both from within the directory where mprime is.

Also print the contents of "/etc/mtab" here, maybe via:

cp /etc/mtab mtab_copy

What is the response to the following command?

(Sorry, I don't know where the line breaks are supposed to go. I transferred the mtab_copy file to a Windows PC for uploading here, and Notepad doesn't seem to recognize its CR/LFs. Maybe they came out OK when I put the CODE tags around it.)

FWIW, this is a Live DVD system.

Hope these printouts help to track down the issue!

Is the thumb drive being mounted read-only?

[paulunderwood]

This link has the answer. You will need to "umount" the drive and remount it will the "exec" flag, but heed the warnings about every file then being executable.

ls /media/FC30-3DA9

This will check you have the right drive. (You have 2 vfat drives.)

umount /media/FC30-3DA9

Then remount it with the "exec" flag:

mkdir /media/FC30-3DA9
mount -t vfat -o rw,auto,user,fmask=0022,dmask=0000,exec /dev/sdc1 /media/FC30-3DA9

(You might have to precede umount, mkdir and mount with "sudo" if you need root permissions.)

[Rodrigo]

Wow, that worked!! (For the benefit of anybody later looking to do this: I did have to sudo in order to perform the mkdir and mount operations.)

Thank you very much, Paul.

Now I can perform the comparison.

One last, quick question:

If I want to convert all those files back to non-programs (for example, so that I can copy the pWxxxxxx files back to the original location to run in Windows), do I umount and then mount again as given above but leaving out the "exec" part? Or do I need to do something else?

You don't need to do anything. The "exec" flag allows files to be executed as programs as well as anything else.

Many file systems are mounted executable by default. Some removable devices containing file systems are not so mounted to protect you against sundry nasties. Anyone else here old enough to remember viruses being spread by floppies?
