Slow transferrate from camera to hardrive

Transfer images from my camera (Ixus40) to the hardrive takes for ever. The dialogue box under KDE keeps alternating between the statuses "Downloading", "Stalled", "Initializing camera", like if it disconnects all the time.. I dunno. Is it supposed to be like this? Under windows I could easily transfer a couple of 100mb in less than a minute..

Open a terminal and tail your logs during the transfer - that will give you a better idea of what's going on.

Are you using the camera with USB Mass Storage or with gphoto2?

Probably because whatever method used to mount the camera is not using the "async" option?

Re: Slow transferrate from camera to hardrive

Canon cameras use by default their own proprietary protocol, which is a pain.
Switch the mode to PtP, and then use a gphoto2 based application to get your job done.
Mass Storage should be easiest, but very few Canon cameras support it.

Re: Slow transferrate from camera to hardrive

I'm using gphoto2

What logs should I tail though?

The camera automounts when I connect it. To use async, do I have to manually mount it then, or is there some way to set that up for automount?

/var/log/everything.log, to start with.

Doesn't apply for gphoto2 - async is for block devices such as USB Mass Storage.

It's a bit weird at the moment. I use the "kstorage" applet so when I plug in a USB flash drive or camera it pops up on the panel and I can mount it (then safely remove it when done and the applet disappears).

I noticed my weekly backup of /home to flash drive started taking a long time and sure enough "mount" showed the sync option:

/dev/sda1 on /media/disk type ext2 (rw,noexec,nosuid,nodev,sync)

BUT when I plug my Fuji A350 in and click "mount"  on the storage applet, a "mount" command shows no sync option (async is the default):

/dev/sda1 on /media/disk type vfat (rw,noexec,nosuid,nodev,noatime,uid=500,utf8,shortname=lower)

I just created "/mnt/usb" and put the following in /etc/fstab

/dev/sda1      /mnt/usb         auto      defaults,user,async     0      0

(async explicitly set as a note to myself).

The storage applet still works and both devices are mounted "async"
