Hi Doug, But if it runs out, nothing happens...as long as it's not in the middle of writing to the flash/disk. If you are only reading the files, there should be no detriment from a power failure.

The reason I was told to never run the camera to the computer is that the camera can fail electronically--battery runs out, etc. doug -----Original Message----- From: "Don Williams" <dwilli10@xxxxxxx> Sent 7/14/2010 3:23:53 PM To: rollei_list@xxxxxxxxxxxxx Subject: [rollei_list] Re: OT: My Computer Knows my DSLR!

As noted before, take the flash card out of the camera and transfer the data to the computer via a card reader. Don't try and figure out why it doesn't work, just accept that you computer has good judgment in refusing the connection. Good judgment is hard to come by. I never, ever connect the camera to the computer. Best--Doug Interesting. I generally just plug the USB cable from the computer to the camera and the camera then reports, on the back screen "PC Connected". I then download the new pictures I want to send right away. Only been doing this with 3 different digital cameras for about 5 years and have never had a problem. One thing I do, however, and this was in a note to Marc- I always use the little "Safely Remove Hardware" icon on the lower taskbar and turn the camera off before disconnecting the cable. My cameras all look like external disk drives to the computer, which is running, at the moment, Windows XP Pro. It's all a matter of taste and I like the speed and convenience of my method. On the other hand, when I visit my kids in San Diego, one of my daughters always grabs whatever camera I happen to have brought along, pulls out the card(s) [one camera has two different types of cards in it, the Olympus EVolt 500 series] and copies everything to her computer. (I do ask her to set the card to "write protect" when she does this. If you then put the card back into the camera with that still set, the camera reminds you.) There is one warning I would give in any case- Never try to use the computer to delete a photo from the card, whether the card is in the camera, or in the computer slot or card adapter. The camera needs to handle image deletions to keep track of what happened to the image. You will probably find that specific warning in all digital camera manuals, but it's easily overlooked. DAW
