Sorry,  my mistake. I don't do these things too often.


[root at localhost par]# /sbin/fdisk -l /dev/sdf

Disk /dev/sdf: 4089 MB, 4089445376 bytes
33 heads, 63 sectors/track, 3841 cylinders
Units = cylinders of 2079 * 512 = 1064448 bytes
Disk identifier: 0x7ef87cc2

   Device Boot      Start         End      Blocks   Id  System
/dev/sdf1               1        3842     3993583    b  W95 FAT32

But I cannot see any message here that points out what goes wrong -
why it is set to readonly.
