Based on my experience, I would advise against trusting a "thumb drive"
or a memory chip to store data over the long run. A month or two,
probably OK.
I had a SD card with student grade spreadsheets for two or three years
of classes plus other data. The card was in a pocket PC. One day the
SD card indicated that it was not formatted. I tried to retrieve the
data with several data retrieval programs but there was just too much
data and too much unknown code on the SD card to be intelligible.
Fortunately, I had backed up the SD card to my hard disk so that only a
small portion of the data on the card was lost. (BTW, I reformatted the
SD card and it has functioned well since then.)
In another case, I used a 2 GB SD card to take pictures with a digital
camera during an European vacation. After copying them on return from
the vacation, I removed & saved the SD card, switched it to read only,
and stored it in a desk drawer. Two years later, I found that about 2%
of total number of pictures on the SD card were no longer recognizable
as jpg files. All the copied pictures were still good when viewed from
the hard disk.
So far, I have not had any trouble with a USB flash drive but then I
don't store data there for archiving -- mostly to transfer from one
computer to another over the short run.

I think at this point I'd just keep some cheapo thumb drives around. You
can get 8 gig drives that size of chiclets. Format them in a manner that
can be read by any system.

Thew reason Windows changes the flag when you move a file to a writable
media, is that when you write it to a CD/DVD it becomes readable only.
Once it is put on a media it must change the flag otherwise it would error
out all the time when you try to change or write a file to your CD/DVD
I think the only way to change that is if you used your CD/DVD as a
harddrive and have the programs loaded to do that.

I never said it wouldn't store the attributes. That's exactly what it is
doing. If you zip the file and then burn it to cd, it only locks the zip
file.
Windows xp and vista/7 seem to decide that since you are moving a file to
a
cd, it will lock the file from being changed. Tom's problem is even after
moving the files from cd to HD he can't change that back. So you zip the
files you want to move, then burn it to cd, it only locks the zip file.
