Possible compatibility issue with TP 2 and 16Gb class 6 microSDHC

---

I have a T-Mobile TP2. I also have an A-Data 16Gb class 6 microSDHC card.
Intermittently, the 16Gb card will "disappear". When starting Copilot Live 8, I will get a message indicating that there are no maps installed. Maps were originally installed on the 16Gb card. Additionally, when I get this error, the Storage Card is no longer available in File Explorer or any other app.
All I have to do to restore functionality is to remove/re-insert the card or do a soft reset.
Here is a link to the card I purchased:
http://www.newegg.com/Product/Produc...-380-_-Product

I have tried the card in a Cannon SD 1000 and have taken several hundred pics and 10s of videos with no problem (thanks to my kids for helping out here!)
I also am now using my A-Data 8GB class 6 card in my TP2 and have NOT experienced the same problem.

I have contacted T-Mobile US, A-Data and HTC.
T-Mobile and HTC offered no help. T-Mobile did offer and has sent me a compatibility list of cards that were tested by HTC.

A-Data has agreed to RMA the card so we can be sure that the card (well we hope) is not the issue.

Is there anyone else out there that has tried this particular card or another 16Gb Class 6 card in their TMO TP2, or any other TP2, and run into similar issues?

Here is the compatibility list I received from T-Mobile:
ADATA 4GB
ADATA 8GB
Kingston 4GB
Pretec 4GB
Pretec 8GB
SanDisk 16GB
SanDisk 1GB
SanDisk 2GB
SanDisk 4GB
SanDisk 4GB
SanDisk 8GB
SanDisk 8GB
SILICON POWER 4GB
SILICON POWER 8GB
Toshiba 4GB
Transcend 1GB
Transcend 2GB
Transcend 4GB
Transcend 8GB

I have the same problem with the disappearing sd card.

mine is a transcend 8gb sdhc, and disappears at random times when listening to music from the sd card (with every player I have tested, the touch flo integrated player, windows media player, coreplayer and nitrogen)

tested with the default rom (asia wwe 1.19.707.1) the updated 1.19.707.2
and with a couple of winmo 6.5 custom roms.

It doesn't happen with video though. I have watched a couple of 30+ minute videos with coreplayer without problems, but maybe it was just luck.

Oh no! That makes it sound like it might be an inherent hardware issue in all TP2s! unless the driver code is the same across all of the different ROMs you have tried.
Not good news at all!

I've had a few of problems with a SanDisk 16 gig card seeming to disappear while still installed in the phone. Can't remember where or when exactly it was, but it was mentioned on here that from time to time, the filing system on the cards gets screwed up by Windows Mobile, requiring a complete reformatting of the card. Since then, I've kept a regular backup of my card, just in case. needed it a couple of times too.

Hope the above helps.

I am using a SanDisk 8Gb Micro SDHC and have also had the disappearing problem. I was not playing any content off the card. Just a few times when I went to get some pictures or files off the card or save an attachment, the card was missing/unavailable. I removed it and put it back and then it worked, but eventually became unavailable again.

I have a 16Gb A-Data card and have had no real issue. The only problem I have noticed, is if I charge the phone fully with the phone turned off & SD card in place, it then doesn't recognise the card. I then had to remove the card and access it via the PC before the phone would recognise it again - however no data was lost.
This doesn't happen if I charge it with the card removed, or if I charge it while the device is on.

Other than that it works fine - but I don't use coPilot.

Cheers,

fyi,
no problems so far with a Transcend 16GB Class 6 MircoSDHC (TS16GUSDHC6) in combination with a german T-Mobile MDA Vario V (Touch Pro 2).

I have the same card with the exact same problem. Re-seating the card fixes the problem for a while. But at least once a day it gets lost. I did not have any issues with a Kodak 4g card.

RiData 16GB Class 6 in Telus TP2

---

I have a RiData 16GB Class 6 in a Telus Touch Pro2 and have not had any problems with it. I have been using it constantly for over a month without a single problem. I would suspect the card as the TP2 is stated to handle 16GB and I am sure it will even take a 32 GB when they come out.

I have takeMS 8GB Class 6 card and initial UK Pro2 and card disappears whenever I listen to music regardless of player. Luckily card never disappears when I use TomTom or Garmin for navigation.
Currently this makes my Pro2 obsolete for listening music. I just hope that changing card will help with this issue.
