JaZip claims to be able to query and change the write protect status of
a Zip or Jaz disk. See: http://www.scripps.edu/~jsmith/jazip/
I haven't tried it recently, but the last time I tried to compile it, I
had lots of problems with the xforms library on which it depends.
Perhaps I'll try it again.
At least one version of the (jaz) tools disk uses the password
"APlaceForYourStuff". It is apparently provided in clear text in the
reclaim.exe utility.
A post on linux-security also stated that it may be possible to beat the
write protect with a read-write disk, a needle (to force eject), and the
write protect disk, which you just put in after ejecting the read-write
disk. Apparently the Zip disk doesn't recheck the permissions.
