Mike,
I had something similar happen to me several years ago when flash
drives were new. I went to the maker's web site and got the solution. I
really don't remember any details, like whether the solution was in a
FAQ or whether I had to email them. but it did work. I sort of remember
downloading and running something. Sorry, but it was a long time ago.
Still, try and see what PNY has to say.
I have used Linux partitioning tools to repartition a 512MB flash drive
into a 64MB ext3 partition and a 448MB FAT32 (aka vfat) partition. That
suggests that another possibility (after first copying your files off the drive to a safe place)
is to delete and then re-create the FAT32
partition on the drive. Of course, if the write protect switch is some
sort of sneaky, low level, semi-firmware type switch, the partitioner
may not be able to touch it either.
Good Luck,

Mike,
Don't know if you have solved the problem yet but there are a few of
ways to view what is ACTUALLY on the drive. These all take advantage
of the fact that in UNIX all devices are treated like files and all
files 'can' in most circumstances... be treated like devices.
mount the drive and then do:
cat [full drive path] > /tmp/foo Then do vi /tmp/foo
strings [full drive path] | more
OR for a MORE detailed view
od -c [full drive path] | more
There are still other methods but these are 3 of the simplest and give
various degrees of detail. All require some time commitment depending
on the number files that are hidden etc. etc. Familiarity with
directory and file delimiting control/escape chars and the "FILE"
structure is helpful.
Good luck!

have a 4GB PNY thumb drive that has issues? It has become "Write
Protected". It is an Optima pro Attache. I searched the net and nothing
that I have found has helped me out.
Has any one in the group had this happen to them and how did you remove
the write protection.
I cannot see any special files on it except 2 of my own.
Any suggestions out there?
Thanks
Mike Enriquez
