I have an HP Photosmart 315 that I can mount fine, get all the picures off and then unmount. However, if I try and remount it, it gives me

/dev/sda1 is not a valid block device

If I want to mount it again I have to restart. Any suggestions?

Do a "lsmod" before and after.


John

that didn't work, any other suggestions?

Do you have an entry in /etc/fstab for your camera.
If yes, what does it look like ?

You aren't unmounting the drive while still in the directory, right?

I don't have an entry for it in fstab and no I am not umounting it while still in the directory.

cdrecord --scanbus
will give some info on scsi devices.
Is there any difference in the information before and after mounting (and unmounting) your camera?

Before disconnecting each time you should try:
(Depending on your distro you might need to do this as root)

eject -s /dev/sdXY
( eg: eject -s /dev/sda1)
Where XY == the specific device you had mounted up (naturally...)

This will "eject" whichever device you had mounted up making it safe to disconnect. I had to do this with my iPod to get it back to a normal screen before disconnecting. I'd imagine your camera is doing the same thing. Though likely you asked this question more than a year ago so you won't see this suggestion, but maybe somebody else will

post your lsmod before and after!!!!!!!!!!!!

Who's. Mine?

My debian's at work, I'll be happy to post an lsmod before and after (mount or unmount? both?) on Monday
