First, my apologies if this is considered a double-post, I posted this question on the Fedora Forum and had no luck.

I have an older Dazzle 6-in-1 flash card reader (USB 1) that works fine with everything else I've put into it. It reads a 2 gig part without a problem, but if I put in an 8 gig part it doesn't see it. The 8 gig part works fine in the Casio camera, but no luck here (MythDora 10.21, with Fedora 10).

I plugged the reader into a Win2000 box and it offered to format the SD card, so apparently it doesn't like it either. Any suggestions? Shall I replace the reader?

The 2 gig part is Q-Memory, 150X, Xpress Turbo, 2 gig, SD
The 8 gig part is PNY 8GB SDHC

Is your card reader SDHC compatible? Older ones usually aren't. SD is not equal to SDHC.

Please consult your package/card reader manual or anything else where accepted card types are listed.

No, my reader was probably made before SDHC existed. So that probably explains it, I need to get a current reader. I didn't realize there was a hardware change that obsoleted the older ones. Thanks for the help,

BTW They seem to be quite cheap at the moment (<1$ on eBay US).
I paid like 5€ for my reader (one year ago or something).

Right, they are generally pretty inexpensive. But I didn't want to waste time looking at readers if it was a different issue. After looking around some, I see that some readers support SDHC and some don't, so that's probably it. Now I just need to find one I like. Thanks again for the advice.
