I've got a coolpix 3700, that mounts perfectly with Mdk10.
But for security of your data, you should know that you must not use supermount!
You should disable supermount, and make it user-mountable. Then add a mount-applet for it on your desktop. That's because it is using the MSDOS filesystem, which is very fragile, and AFAIK, there's no way the coolpix could do a fsck in case of trouble :lol:
Also, you say that it shuts down. That's because it is too long on. There's an option in the coolpix' Setup menu for having more time before shut-down.
And yes, it is slow. That's because the coolpix' processing power is far bellow that of your PC. Besides, it is probably using the USB1 protocol. I was suggested to use a SDcard reader for the PC, but I did not try, yet.
BTW, I had a strange problem with my coolpix. May I ask if you encountered the same or heard about it:
I was on holliday, and one day, the camera displayed "This card cannot be used". I shut it down, then powered it again, and all was OK, except the 2 photos, and 1 film, I had on the card were not there anymore! 3 files is not a lot, I let it go. I took tens of photos/films, and then 5 days ago, the error message appeared again! I lost everything! So I decided I would look on the computer what was on the card. I pluged the coolpix, and mounted it, and what did I see?? The 3 old files of the beginning I thought were lost forever!!! But only those unfortunately
