I'm having an odd problem. I have two Transcend 16Gb CF cards that I bought used. They had been used in a Nikon before.
When I used my Kingston card reader to try to format them in my Vista laptop, I got a message that they had to be formatted before use, but when I tried to do that, it said that Windows couldn't do the format.
I put them in my 7D and formatted them there. Now when I insert one of the cards in the reader it pops up as an EOS_Digital drive, and everything is fine.
The laptop continues to refuse the recognize the second card. Autoplay doesn't pop up, it just shows up as an external drive in Windows Explorer. I can format it in the 7D, it writes images to it that I can view on the camera LCD, but I still can't view the card with the laptop.
Edit: Tried another laptop running Windows XP, and I have the same problem.
Any ideas? I fly out to a location later this morning, and I could really use this card!
Goto Control Panel/Admin tools/Computer managment/Storeage/Disk managment
you will probably see the card listed there but it may say it needs to be initialized or something like that.
If it does download some CF tools (maybe from transend) that may get the thing going again (sort of a lowlevel fornat).
Its happend to me with drive before. I could use it attatched to another PC but my vista desktop would not play with it.
Thats good. first thing to do would be download the images from the camera. It probably is able to do this as the camera is not seen as a mass storage device. otherwise it would have to be assigned a drive letter and unless its you card reader thats at fault (possible) you would probably be in the same boat.
Just thinkimg about it if you bought the cards used (which is risky unless you know the previous owner ) do you know if the previous user had any problems with them? and is the card in good condition with all the pin holes clear?
I do know the previous owner - not worried about that. Card looks new. I'll be with the previous owner this weekend, so we'll see if he has some ideas too.
I'll just use this card last, and since I can get to the images through the camera, it will be fine.
