SDHC support died on my 211

I've been using a 32 GB SDHC card on my HP 211 since February without any problems. One day about 2 weeks ago, though, The iPAQ suddenly stopped recognizing the card. The 211 knows its there because it wakes up when the card is inserted or removed, but the card does not appear in the file manager or under Storage Cards. I've tried two SDHC cards, but neither works in the 211 now. However, smaller SD cards work fine. Both SDHC cards work fine on my PC. I reformatted the cards, but that made no difference. I've tried resetting twice, but that made no difference. The totally clean 211 after a hard reset still won't recognize the cards.

This seems like a driver issue, but a web search doesn't turn up any significant help for WM6. I didn't install any software in the time before this happened, but the hard reset should have neutralized that issue anyway. I check out the sdhc_navajo.dll, sdbus.dll, and sdmemory.dll driver files with SKTools, and they all appear to be loading normally with their services available. The dates on the files are 1/1/08, so they haven't been replaced. SDI8686.dll has been superceded by a 1/30/08 file, but its earlier version makes no difference after a hard reset.

I'm out of ideas at this point. Anybody have any ideas on how to get the 211 to recognize SDHC cards again?

Have you tried reformatting one of the SDHC cards.
It might just be a problem with your cards rather than the device,
Copy everything off the card to your PC then format it and try again, that should eliminate the card as a problem, if nothing else.

Yep, I reformatted the cards on my PC. I also downloaded and used Sandisk's SD/SDHC formatting utility. Didn't help. I've tried everything with the card, including RMAing the first one because I thought that the original problem was the card. Since the cards work perfectly under both Linux and WinXP, I'm down to the iPAQ now.
