• The problem is not limited to SanDisk cards
• About half have had success with Lexar cards, judging by here and the Dell Community Forums
• Many have tried SimpleTech cards with no problems, so it looks like your best bet
• Some believe the sticker on SD cards has paint that short-circuits it, and the problem can be solved by removing it (this will void the warranty)
• Putting tape over the sticker on the SD card did not help
• Dell is quiet about the issue, and "Dell-Rollie" on the community forums insists this is not an issue with the Dell Axim
• A Dell Axim replacement has helped one user on the community forums

WEll so far I haven't encountered any complaints about PNY or panasonic SD memory cards so those are fine as well.

PNY is working great for me. My problematic SanDisk card exhibits even worse symptoms in my PC reader, sometimes requiring me to remove the reader and reboot before it will recognize any other cards.

It's not a Dell problem, but the Axim seems prone to aggravate the issue.
