gm Hey folks, I sometimes make the stupid mistake of trying to write to a
gm write protected floppy. Problem is, once I correct this oversight, I still
gm can't write to the disk. In fact, I am unable to write to any floppy in this
gm drive without rebooting. The permissions are okay. Anyone else run into
gm this problem?
I don't experience this. I just did the following:
1) placed write-protected diskette in fd1
2) mounted the disk on /dos_b or /lin_b -- and got "write
protected" message (and Linux correctly determined the
diskette sizes)
3) attempted to copy a file to that diskette, and was
refused:
cp: cannot create regular file `/dos_b/test_file': Read-only file system
4) umounted the diskette and moved write-protect tab to 'unprotect'
5) mounted the diskette, copied the file successfully, deleted the
file, and umounted the diskette.
This worked with DD and HD, mosdos and ext2 file systems: no lockups.
Warnings and activity of write-protection look OK to me. I did _not_ try
to override write-protection as 'su' - was that in your scenario?
Attached is the relevant section of my /etc/fstab:
/dev/fd0 /dos_a msdos user,noauto,rw
/dev/fd0 /lin_a ext2 user,noauto,rw
/dev/fd1 /dos_b msdos user,noauto,rw
/dev/fd1 /lin_b ext2 user,noauto,rw
Ahdunno ...
