Linux (Maybe OSX) USB Mass Storage How-to

[mobile619]

I read in this forum that some people were having problems with the Sanyo M1 while using it has a USB Mass Storage Device with Mac OSX.

I had some problems while using it with Ubuntu 6.10 and it might be the same problems so I decided to post my fix.

When I try to umount (eject) the Sanyo M1, it fails and none of the files are written to the phone.

Possible FIX for Ubuntu 6.10:
1. Plug phone in and put in Mass Storage mode
2. Wait for phone to be auto-mounted (My phone is mounted at /media/usbdisk)
3. Open terminal
4. Determine hardware location of phone in /dev/ folder typically (/dev/sda1) do this by running 'cat /etc/mtab' You should see something like this at the end of the file
/dev/sda1 /media/usbdisk vfat rw,nosuid,nodev,quiet,shortname=mixed,uid=1000,gid =1000,umask=077,iocharset=utf8 0 0
5. Umount (eject) the phone.
$ sudo umount /media/usbdisk
6. Re-mount phone with new options
$ sudo mount -t vfat -o uid=1000,gid=1000,umask=077,nosuid,sync /dev/sda1 /media/usbdisk

I think the 'sync' option is the key. And remember to replace '/dev/sda1' and '/media/usbdisk' with the values determined in previous steps.

I am also trying to find a way to change the defaults options to include the sync option.

I hope this helps.

WARNING: the sync option may shorten the life of a flash drive

From the mount man pages
sync
All I/O to the file system should be done synchronously. In case of media with limited number of write cycles (e.g. some flash drives) "sync" may cause life-cycle shortening.

Ok, I think I've determined a more permanent fix.

1. Open terminal
2. Edit HAL config file
sudo gedit /usr/share/hal/fdi/policy/10osvendor/10-storage-policy.fdi
3. Scroll down until you reach the section below:
<!-- Attempt mount point 'ipod' for iPod's -->
<match key="@block.storage_device:portable_audio_player.type" string="ipod">
<merge key="volume.policy.desired_mount_point" type="string">ipod</merge>
</match>
4. Copy and paste the following text just below the ipod section

<!-- Attempt mount point 'sanyo_m1' for Sanyo -->
<match key="block.storage_device" string="/org/freedesktop/Hal/devices/storage_serial_Sanyo_Mass_Storage_000000000003">
<merge key="volume.policy.desired_mount_point" type="string">sanyo_m1</merge>
<merge key="volume.policy.mount_option.sync" type="bool">true</merge>
</match>
