This is how the phone set up the mini-SD card. If I change things, then I don't know how the phone would react. The main concern is that it work properly in the phone. I can work around its idiosyncrasies in linux whenever I need to transfer photos off the phone, or other stuff to the phone. -- Walter Dnes

The partition table may be slightly faulty, hence the need for fdisk.

I like to be in control of what gets mounted when. Thanks for the explanation. With it in mind I've finally come up with a plan that works. In /etc/sudoers.d/001 I've included... waltdnesi3 = (root) NOPASSWD: /sbin/fdisk -l /dev/sdc And there's an entry for a vfat device in /etc/fstab for directory /mnt/extc. The command "/sbin/fdisk -l /dev/sdc" seems to read in the partition table into the system and things work from there on in. fdisk only works as root, hence the sudo command. Here's a sample session... === waltdnes@i3 ~ $ mount /mnt/extc mount: special device /dev/sdc1 does not exist waltdnes@i3 ~ $ sudo /sbin/fdisk -l /dev/sdc Disk /dev/sdc: 16.0 GB, 16012804096 bytes 256 heads, 63 sectors/track, 1939 cylinders, total 31275008 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x Device Boot Start End Blocks Id System /dev/sdc1 *20483127500715636480c W95 FAT32 (LBA) waltdnes@i3 ~ $ mount /mnt/extc waltdnes@i3 ~ $ === The mount after "sudo /sbin/fdisk -l /dev/sdc" is successful. So all I need is a short script "~/bin/mntc" like so... #!/bin/bash sudo /sbin/fdisk -l /dev/sdc mount /mnt/extc -- Walter Dnes
