The greatest likelihood, if you're using NiMH batteries, is that they
are unable to sustain the power demanded by the transfer
consistently. NiMH batteries seem to be best at modest duration
bursts on power delivery. Pentax recommends using the external power
supply when connected to a computer for file transfer.
This is conjecture ... if the problem is happening when you're
connected and using known good CRV3 or AA Lithiums, then I don't know
what the problem might be. I use a card reader, and have always done
so. I use a Belkin 8-in-1 USB 2.0 reader. For $25, I find it very
convenient and reliable; I don't like to have to keep plugging and
unplugging my camera from the computer.

I keep losing my connection for some reason. I will be partially
finished with transferring all the images from my 1GB SD card to
the PC, when the transfer simply hangs. I can look at the list of
drives in Windows Explorer, and the "removable drive" which
represented the *istDS no longer appears in the list at this point.
I find that I have to turn the camera's power off and back on to
restore the connection. At that point, I have to start copying
files again, picking up where the previous attempt had failed. This
happens most of the time to me, and it's getting annoying. I just
wondered if it ever happened to anyone else on the list?
I should mention that this not only happens if I try to drag and
drop the files using the Pentax Photo Browser, but also when I use
Windows Explorer to drag and drop the files.
Maybe I should just get a dedicated card reader and not use the USB
cable for transfers?
By the way, I tried the "Remote Assistant" software which was
written for the *istD, and it does indeed work on my DS model. So
far, there have never been any connection problems when using the
Remote Assistant software, but I have to admit that I haven't been
using this particular software for very long.
I also managed to update the firmware in my *istDS via the USB
cable without any problems. It's only the picture uploads I'm
having problems with.
take care,
Glen
