Other Cannot format directly or write an image file to a floppy disk

[AlexDarkVoid]

Either attempt: [a] to format a floppy disk (via USB adaptor; detected as /dev/da0) using newfs or newfs_msdos, or to write a preformatted image file with dd result in the error message:
/dev/da0: Read-only file system
If I format the diskette or write the image under other OSes, it can be mounted in read-only mode. If I try to mount in rw mode or create a new partitioning scheme (gpart destroy da0), the same error message pops up. What's wrong?

have you checked permissions on the usb device involved?

 

[atax1a]

is the write-protect tab on the disk "open"? that locks the disk, slide the tab so it's closed.

=> [tingo] Running all commands as root.
=> [atax1a] Nope, the FD's latch is closed.
Another strange thing: today mount gives this: mount: /dev/da0: No such file or directory.
Meanwhile, it doesn't complain when -r option is given.

You need to backtrack a bit:
1) how does the usb floppy drive show up in/var/log/messages when you plug it in
2) how does usbconfig report the usb floppy drive

Problem solved. The culprit was a fautly FDD. Bought another one from a different manufacturer - and it worked just fine.
