A free 8GB USB key given to me shows up in Snow Leopard as read-only.
$ mount /dev/disk1 on /Volumes/USB DISK (ntfs, local, nodev, nosuid, read-only, noowners)
How can I mount it read-write? According to the provider of the USB key:
"The USB needs to be unlocked. Right click USB-properties-security-select everyone-edit-permissions for everyone-Allow full control"
But I think these must be instructions for a different OS.
I'd be fine with reformatting it - there's nothing valuable on it.
Attempting to force the issue with
mount doesn't seem to work:
$ sudo mount -w -t ntfs /dev/disk1 "/tmp/USB" $ touch /tmp/USB/foo -bash: foo: Read-only file system
