why read-only?

[Dave Stevens]

I have an 8 gig usb flash drive attached to my U12.04 netbook. I can
write files to it but can only sometimes erase them.

so:

dave at wiggle:/media/F0B0-1A76/forgeodora$ rm 1541
rm: cannot remove `1541': Read-only file system

but in /etc/mtab is:

/dev/sdb1 /media/F0B0-1A76 vfat  
rw,nosuid,nodev,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush,uhelper=udisks 0  

which _seems_ to be read/write.

Anyone have a suggestion?

Dave
