Tytn freezes because of micro SD card, help!!

[eldali]

My device switches on by itself and then crashs with the screen on, it is not possible to access any thing and the only thing it responds to is to do a soft reset.
The only difference between now and when it was working fine is the usuage of a micro SD card. My device works perfectly when there is no SD card installed, if I install a SD card the device starts to show the stange behaviour straight away.
The SD card which I am using is a 1 GB Sandisk card. What do you think? Do you think it is a device hardware problem or what?

Thanks in advance for any offered help!

Have you tried reformatting the card in a PC card reader? FAT32, allocation size of 512. and make sure contacts on card are clean.

I did that already but with no improvement. What I don't understandis, why my device switchs on by itself, as if it detects a new SD card inserted while it is off!!
I don't want to be fast concluding it is a hardware problem, it is still under warranty, but I would like to send it only when I am sure it is hardware problem!

Need to establish if it's the card or device. Don't suppose you can access another card?

I have only one card, it seems I will have to buy another one, just to do the test! I will do that today in the evening, unless someone has better ideas.

thx

There's a bit discussion going on already... see this thread: http://forum.xda-developers.com/showthread.php?t=294324

Well, I had some similar problems. Now I make sure that EVERY application & service running is on the main device memory (RAM). eMail attachments, browser cache, all today add-ons and all applications that run with a schedule (like Backup etc.) - Only documents, Tomtom Maps and Games are left on the SD card. Reduced freezes to one in a week.

Well, and I just ordered a Kingston card and will compare it to SanDisk. Both 2GB.

I tried another 512 Mbyte card, it seems better so far (only since 1 day). I didn't have any freezes, but the device wakes up by itself from time to time, although the option to wake up when a key is pressed is disabled. I can't understand this!!

Kingston 2GB card working perfect so far. Running WM6 (check my signature).
