Is trinity 4 GB miniSDHC compliant?

[bouaroudj]

I read in several forums that the new mini sdHC cards can be read only on mini sd 2.0 compliant phones.
Is that the case for the trinity?

[adewidt]

There is a dll on the device called sdhc_....dll

It look likes there is support voor sdhc.
I don't have a sdhc card. I can't confirm it is working.

I have a 4GB Mini SDHC Card by Transcend (www.transcend.de). Until now I don't get it to work. I bought a HAMA 1000&1 Card-Reader, but it is not able to format the Card. So I brought it back to the store. There I could format the Card with a new digital camera by panasonic. The 4 GB MiniSDHC worked well in that camera. Back in my Trinity P3600 nothing happens. I tried Pocket Mechanic and SK Tools and Resco, but the Card is not visible. In the Registry I found SDHC mentioned. But it doesn't work. Any ideas?

Uh oh, I just ordered one in the US for $66. from newegg.com, which is a good price, but only if it works! The 4gb mini SD from Moby Memory is generic with no label. I wonder if it is really SDHC???? 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 :mad: .

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.

Thanks so much for all that info. That is exactly the reason that I didn't order the Moby Memory, I was pretty sure that it wasn't the official SDHC card. I hope that the new ROM from Dopod fixes the SDHC. Early adopters have all the fun :-)

Just got the Transcend 4gb. Can't see it. Has anyone been able to get this card to work in a Trinity?

Read the above posts about compatibility. If you have the Transcend 4 GB miniSDHC, that card will NOT work in the Trinity. There is NO confirmation from HTC that a miniSDHC (ver.2.0) will work with a firmware upgrade in the future. Even though the miniSDHC fits in the Trinity slot, it may need different slot hardware to read it. Let's hope the SD controller already there in Trinity can support a firmware upgrade.

If you look around you may be able to find a 4 GB miniSD (Industry Standard version 1.0). Most of the ones on ebay & Amazon are fake though. When I find a confirmed source for a 4 GB miniSD (ver.1.0), I'll post it here.

[Baxter]

I have read them and I understand. I only asked because from the previous posts, it wasn't clear whether or not the Trinity can read the MiniSDHC v2.0 cards.

[export800]

according to the HTC site the maximum size of the mini-SD card for the Trinity is 12GB.. though who really knows for sure ;)

http://www.europe.htc.com/support/faq.html?id=29

Support: HTC P3600
What is the maximum SD card size compatible with my device?

For Win CE 2003 =>General for SDIO is 1GB.
For WM 5.0 => SD Card is 4GB and Mini-SD is 12GB

Well, someone knows for sure, the guys writing the firmware ROMs. I suspect it is just a matter of time before a ROM update comes along that will allow the use of SDHC cards since the entries are already in the current ROM.

Ordering a 2gb v1 card. The way prices are...

1. Notice that almost ALL phones on HTC site say the same thing about SD & miniSD limit. It is based on WM5 & WinCE2003 specs, which HTC phones use, a generalization.

2. IF HTC has SD controller hardware (memory slot interface) in Trinity, that can be enabled by a firmware upgrade to recognize & read SDHC, then as Matterhorn said, we should get a ROM upgrade to make this possible.(nobody knows & not confirmed by HTC, but we can
hope.)
If HTC doesn't have the SD controller that's amendable to firmware upgrade, then a new hardware build of Trinity would have to be released.

3. It's interesting that Trinity registry entries exist for SDHC, but it's still a mystery for now. Also, there are supposedly 4 GB miniSD cards (based on Industry Standard 1.0 or non-compliant) that exist, but I'm not able to confirm one that is genuine & safe to use
in Trinity yet. (if someone is, please give details)

4. Good news...bad news---
good-4 GB SDHC can use fat32, is faster than old regular ver 1.0 or 1.1 Standard----
bad-reportedly, the new SDHC cards will be 3X cost of the regular ones.

5. Compatibility
* SDHC Host Products can use both SD and SDHC Memory Cards.
* SD Host Products can use only SD Memory Card 2GB or less.

Is Trinity a SDHC host product or SD host product? THE BIG QUESTION (no SDHC logo on box)

The new SD format, SDHC (Secure Digital High Capacity), allows capacities in excess of 2GB (4GB to 32GB)[2]. SDHC USES THE SAME FORM FACTOR as SD, but the SD 2.0 standard in SDHC uses a different memory addressing method (sector addressing vs byte addressing).

6. Feeling Confused? Here's why:

The following compatibility issues between SD and SDHC cards and devices can arise:
Devices that do not specifically support SD2.0/SDHC do not recognize SDHC memory cards.
Some manufacturers have produced 4GB SD cards that do not conform to the SD2.0/SDHC, which are incompatible with existing SD devices, and are also incompatible with SDHC devices. As of late 2006, the simultaneous availability of non-standard 4GB SD and 4GB SDHC cards,
and the incompatibilities between SD and SDHC have caused a great deal of confusion among consumers looking to buy memory for various devices.

4GB SDHC cards can only work with SDHC compatible host devices. The SDHC logo is supposed to ensure compatibility.

SDHC readers and other devices are supposed to be backwards compatible with SD cards.

SDHC cards have SD Speed Class Ratings defined by the SD Association. The SD Speed Class

Ratings specify the following minimum sustained write speed for SDHC cards: Class 2: 2 MB/s, Class 4: 4 MB/s
Class 6: 6 MB/s.

The SD 2.0 (SDHC) specification is with access speed up to 20MB/sec. The maximum capacity of SD card is 2GB under SD 1.1 of Secure Digital Alliance (SDA) specification; however, by using file format of FAT32, many SD 1.1 host devices can use 4GB SD card.
SD 1.0/1.1 uses traditional "Byte Addressing" scheme which limits the maximum capacity to 4GB while SD 2.0 adopts "Sector Addressing" scheme which is the same with the technique applied by Mu-Card Alliance in 2004 to reach the maximum capacity of 2TB (2048GB). SDHC
cards can only work with SDHC compatible host devices.

7. SD and SDHC - compatibility---In summary:
The new SD format, SDHC (Secure Digital High Capacity), allows capacities in excess of 2GB (4GB to 32GB). SDHC uses the same form factor as SD, but compatibility is not complete in either direction. The SD 2.0 standard in SDHC uses a different memory addressing method
(sector addressing vs byte addressing), causing devices that do not specifically support SD 2.0 / SDHC to fail to recognize the memory cards. Making the issue more confusing is the fact that some manufacturers have produced SEMI-NONSTANDARD 4GB SD cards. These cards are incompatible with SD devices that don't support the larger formats, and are also incompatible with many SDHC devices, because they don't conform to the SD 2.0 spec for High Capacity memory cards. As of late 2006, the simultaneous availability of non-standards 4GB
SD and 4GB SDHC cards, and the incompatibilities between SD and SDHC have caused a great deal of confusion among consumers looking to buy memory for various devices.

You little Devil :) ...came up with good info.
My observation is that the 4gb mini SD cards sold by Moby Memory must be FAT32 formatted normal SD standard. Several people have reported that they work fine in the Trinity. I currently use a 4gb "SD" card in my Prophet that has worked perfectly for a year now. It is formatted as FAT 32 and I have reformatted it using Windows XP with no problems. I did buy a Transcend SDHC 4gb mini SD card for $66. in the US (pretty cheap), but I won't see it until I arrive at my holiday destination. I guess I can be sure that it won't work in my Trinity (that's waiting for me also). So unless they come up with a ROM upgrade soon that fixes this SDHC compatibility problem, I'm going to order one of those Moby mini sds. I need 4gb for all my GPS maps and music, pictures etc.

Lets compare the htc p3600 spec sheet and the htc p4350 :
