If it was JUST a driver issue, then we'd only need a new driver for our SD readers to work - after all, the readers are mostly pins and a drive controller to handle the read/write operations.
SDHC won't work with any of the Dell ROM's from Dell. It won't work with most older SD 1.1-compatible readers. It also has speed ratings based on class, which suggest some other methods of handling read/write operations too, especially with the spec sheets I've seen.
For 4GB SD cards which violate the 1.1 standard, you'll take your chances. Some work, some won't. See the thread at the top of the Storage Card forum for a list of known-good 4GB SD cards.
Not true! The WM6 hacked roms give FULL read/write ability to SDHC, so it *IS* a driver issue with the axim (possibly with all SD readers, or it may be the Axim's is really SDHC-ready (i.e. SD version 1234, and SDHC is version 1235, so the hardware is identical) just so old that it wasn't stamped that) But proper drivers WILL enable SDHC support!

I want to see benchmarks between those and an actual SDHC-based device to see if it works as intended (speed included), and I need to see more proof of those cards being filled to the 8GB or whatever they're specified for. Again, if it was JUST a driver issue, then MS could've shipped an SDHC driver for existing SD card readers and we'd be done with it - it's not like SD 1.1 cards can't be formatted to use FAT32; I did that with a 2GB SD card ages ago, and did the same for a 4GB SD 1.1 card from OCZ.
Again, SDHC is a standard that came about two or three years after the hardware for the Axim x50v shipped, and from what I've seen of the SD Association's whitesheets, there is some extra traffic-control stuff on there to allow it to write/read at those faster speeds. Just because SDHC readers are backwards compatible does NOT mean that SD readers are forward-compatible, any more than DVD drive that can read CD-ROMs means that a CD-ROM drive can read DVD's.
At this time, WM5 for the Axim will NOT support SDHC. There are SDHC-compatible products out there, but discussion about the ROM is expressly forbidden in the rules for the MobilitySite forums, and there is no official support for it. SD 1.1 4GB cards are still available, but your mileage may vary.

It is a driver issue. The hardware is SDHC compatible. Microsoft and Dell will not update the drivers so that we will be forced to update our hardware. That's how they get money out of us.
That's the whole reason that SDHC was invented, so that we will need to upgrade.

You could always use a cf card. even the largest cf cards work just fine in the axim. I tend to like cf cards better anyway as they are harder to loose / break.

I agree, there are probably drawbacks, akin to running an USB 2.0 device on a USB 1.1 root hub. I am watching eBay for a good deal on a 8gb SDHC and when I get one I will gladly post benchmarks, but ATM I have no SDHC cards... I dont expect them to perform at exact perfect spec, but if I can get storage capacity, that's all *I* care about, and I suspect what most ppl here care about (since we have 256mb of internal ram and can copy most files there temporarily to execute them, if speed is needed)
As for the driver, tell me, have you seen any drivers for SDHC for, say, the LISA? what about the Atari? TRS-80? these devices are obsolete, so manufacturers are nolonger writing drivers for them. the Axim line is dead, it's just sheer luck that Football's rom had drivers that were compatable.
And @ Jharsh: beleive me, if I knew DLLs and registry hacking, I'd be more than glad to write and post a driver, but sadly I dont...

Windows XP is a 'current' operating system which still has support (Microsoft is talking about XP SP3 sometime this fall) and so is Mac OS X. Ditto Windows Vista, ditto Linux - and there are NO drivers which allow SD 1.1 card readers to read SDHC cards. It's not just the change to FAT32 that makes the difference as far as speed and capacity goes; the key is probably in any changes made to the SD standard to allow them to have Class 2, 4 and 6 speed ratings.
The lack of a standard measure for card speeds was a real problem with SD 1.1 and SD 1.2, especially as people began to use SD cards for digital cameras with 6, 8, then 10-12 megapixel resolutions which meant that the read/write operations involving files up to 5-7 MB in size. The implementation of the speed classes (which specify the MB/s they're capable of writing to, barring severe file fragmentation or reader/writer hardware issues) means they had to do something extra to allow themselves to advertise the maximum speeds with a specific 'standard' rating; this probably means traffic control hardware on the slot itself.
Ah, I see, I thought you meant MS could ship a driver for the Axim; not for XP.
I have seen 1 or 2 devices that were not officially SDHC that can (suppsoedly) read/write to SDHC cards, I am not a hardware tech so I dont know the differences, it might be so subtle that the newest of nonSDHC hardware can read/write to them with a loss of some features/speed.
I'm shopping for an 8gb SDHC, as I said, and when I get it I will post benchmarks on both axim and card-reader (since 99% of the SDHC cards on eBay come with a USB reader for some reason) though I wonder would the stats be skewed with USB 2.0 vs the Axim interface (purely core hardware speed - not card slot)

I am running a 4 GB Q Memory SD card and a Transcend 8 GB CF card. No real issues. Running both cards sucks about 5 MB of RAM though.
P.S. Stay away from computermemorystore.com and flashmemorystore.com. They use bait and switch. You order a more expensive SD card and they send you the cheaper one at the more expensive price.
