Other Help Topics :: USB mass storage support



There are several occasions where I can't mount my USB storage devices.

dmesg shows this:

Mount says that I must specify filesystem type.
AFAIK it's FAT32. Anyway, DSL should regonize FAT32 automatically?
How are you trying to mount it? Hotplug should auto-detect it and set up a mount point sequentially with the recognized filesystem. So the first mount point for a flash device should be sda1, the second would be sdb1, etc. If the device (assuming it's a thumbdrive) is the first one you plug in, you should be able to either mount it simply with "sudo mount /mnt/sda1" from command line or with the right click on /mnt/sda1 in emelfm as described elsewhere. I've never had to assign filesystem types when mounting thumbdrives, flash camera devices, or mp3 players with hotplug.
Hotpulg creates required lines to fstab. It all works just fine until I have to mount.
To be exact: I mount from emelfm while I'm root (as superuser to make somethings clear), of course (so now there's no telling about this). It does just the same.
So there's no question that I don't know how to mount devices (I know also how to mount in command line). There's just an error somewhere. What I'm looking for is to how to fix this error (bug?).
I cannot access to it with fdisk either. It means that this error isn't actually happening when mounting. it occurs earlier (look the dmesg I pasted).
I had this same problem with my Creative MuVo Slim MP3 player.

Are you sure these devices work elsewhere? Have you reformatted them or otherwise done anything with their filesystems? Can you get these devices mounted if you boot with them plugged in? Have you specified a filesystem in a mount command? Please copy your "fdisk -l /dev/sda" (or whatever) here.

Like I wrote while ago, I've never experienced any problem mounting USB storage media with hotplug (including under Knoppix and DSL).

Try rebooting with the USB device (or both) inserted and see if you can mount it after the reboot. If that doesn't work, please paste in your mtab and fstab (along with the fdisk -l devicepath). You can paste those files in if you don't want to reboot. I just want to see that the mount point is created when you plug the device in and what file system its reporting (if any).
Booting computer every time when plugging USB storage device isn't just acceptable.
And yes. Mount point is created. But NOT removed on unplugging.

I never encountered these errors with Xubuntu.
