Card Reader Upload Problem

[adirondackguy]

I almost lost all my photos on my EOS5D when uploading them from a SanDisk 2GB CF Card using a Lexar Multi-Function USB Card Reader (through a Mac G5). My friend uploaded his images and removed the card (without ejecting the card from the desktop).
Later, I inserted my card and it could not see my images - it was, in fact, still looking for the image numbers from the prior card (which I no longer had acccess to). After logging on to Lexar's 24-hour chat support, I followed the instructions and apparently ended up deleting the images. I was able to recover them through SanDisk's RescuePRO, but want to find out WHY this happened in order to avoid a repeat situation. Anyone had experience with this problem?

Help me out here......how did he remove his card without ejecting it? And if he didn't eject it how did you put yours in?

On a mac, you need to "eject" the card from the OS (in the software) before removing it physically (just as on the PC, you have a command stop disk or whatever when you have a USB drive...). If you force eject it, I think that some damage may result... I guess, the safest is to always eject the card first from the finder and then remove it....

Hope this helps ;-)

Same thing can happen when removing the card from the camera without turning it off. Ejecting or stopping just makes sure that the computer is not accessing the card at the time.

If you use a USB card reader you can put the card in and out whenever you want. You only have to do the safely remove hardware thingy when you unplug the card reader. Even then if there is no card in it I don't think it will hurt anything. I swap a card reader and an mp3 player on the same USB port every once and a while without doing the remove hardware thing and have never had any problems.

Obviously, you're not running on a Mac. :)

Are you using some kind of program to read the files off the card reader? If you are, it may be your program that's not behaving itself. I use finder to copy my images from the reader to the computer. And I've never had a problem doing it that way even if I, on very rare occassion, pulled the card out before ejecting it, other than getting that nasty message about how I shouldn't be doing that. :)

I just tried it a couple of times a few minutes ago and didn't have any problems with not being able to read any data from either cards.

I understand that "not ejecting" the card can cause loss of space due to formatting problems. Whenever you re-format the card in the camera after not ejecting properly, the space on the card is slightly compromised. Just what I was taught.
