Confirming...Transcend 4 GB miniSDHC not recognized in Trinity yet.

I am fairly confident though that the Trinity will support the SDHC 4gb mini SD soon through ROM upgrade, if it doesn't already. It has entries for them in the registry already. Otherwise I guess I'll have to get the other card
I purchased a 4 GB Transcend miniSDHC card, upon reading & then seeing that some SDHC parameters were in Trinity registry. However, the card is NOT recognized yet by my new Trinity.
After trying various registry changes in the SDHC area, I still could not make it read the card. I did succeed in making a ver 1 miniSD card unreadable with those SDHC reg changes though, which means maybe we're on the right track. This also tells me that most likely, a compatible device will work for either miniSD or miniSDHC, but not both at the same time. Maybe a registry wizard here will find a way to make Trinity see the miniSDHC cards.
HTC says officially that Trinity with WM5 can accept up to 12 GB miniSD, without mentioning miniSDHC. It seems reasonable HTC may enable SDHC & GPS in the future. However, keep in mind, HTC has not even fixed BT stereo in the Trinity ROM, so we continue to wait & hope.
In the world of miniSD cards, there is ver 1 miniSD standard. (Sandisk is original inventor of flash memory & helps develop International standards) The max miniSD ver 1 standard is actually 2 GB officially.
There are UNOFFICIAL 4 GB miniSD cards, based on ver 1 standard, but NOT accepted as ver 1 standard produced cards, that exist & carry 4 GB miniSD working formatted memory. There are also FALSE 4 GB miniSD cards, that have been re-stamped as 4 GB, but orginally were 2 GB miniSD. Then, they were reformatted for 4 GB, but that process corrupts the memory. Depending on the device, the false miniSD cards either give incorrect readings or corrupt when used with a read-write process. Some apparently work a short time but then corrupt after normal repeated read-write device process use.
The new miniSD ver 2 standard is called miniSDHC. These will be capable of memory 4 GB up to 32 GB. The first miniSDHC & SDHC cards are just now being made available. (coming 2007) Ver 2 miniSDHC is NOT backwards compatible with ver 1 miniSD devices, except in some rare cases where a device firmware upgrade may apply. The 4 GB miniSDHC ver 2 standard, is the only official real 4 GB miniSD card & most current devices can't use it.
The 4 GB miniSD cards sold at Mobymemory (UK) & ebay are either the UNOFFICIAL 4 GB miniSDs or FALSE 4 GB miniSDs mentioned above. One member here claims that a 4 GB miniSD from Moby works in a Trinity, but you can be assured, it's not a real 4 GB miniSDHC ver 2 standard card.
