I have a Canon S1 IS that has worked perfectly for several years. But
just these last few days it's developed a strange fault: when
connected to the USB port of the computer it immediately deletes all
files off the camera!
The camera optics works fine, and the photos (and video) can be viewed
normally on the camera. But on plugging in the USB cable Windows gives
a background messgase to the effect of 'calculating time to move
files..' and then a message dialog stating 'confirm deletion of x
files' (or similar). All files are deleted even if I attempt to cancel
at any point. The above process applies for those USB ports where I
have previously set it up to automatically transfer the files from the
camera to the PC (this historically worked well).
However, if I use a different USB port, one where there is no standard
action, then I can open up windows explorer and manually inspect the
contents of the camera. Again all files are deleted. So it does not
seem to matter in what way the USB connection is made: the files are
simply deleted immediately the USB connection is made.
This problem is repeatable on at least two computers (both running XP
Pro SP2) and with different USB cables. However the problem is
intermittent (does not always occur).
I have spoken to Canon 'camera service' (NZ), who have not heard of
this type of fault ever before.
However, having done some tests, I now think that it ONLY happens
when the camera is plugged in when in POWER-OFF mode. (If the camera
is ON, in either camera or play mode, then USB file-transfer seems to
operate normally, i.e. the files are saved.)
The problem has appeared since the PCs did an automatic Windows
upgrade earlier this week, so perhaps this is the cause? (If so,
perhaps other users of this or similar cameras have experienced this
problem?) Or maybe the Windows upgrade is just a coincidence?
So the work-around seems to be: never connect the camera to the PC
when the camera is powered off.
Any other suggestions or solutions, or even just similar experiences?
Thanks
John
