Sansa Fuze v1 with 64GB SDHC Card - weird problems

[newnoise]

Hi,

I just installed Rockbox on my Fuze v1. Everything working fine. Now I bought a 64GB SDHC Card (a cheap one and my Fuze is not really willing to work with it
I formatted the card to FAT32 put music on and put it into the running Fuze. Everything working fine, I can browse through the files, play them, create the database. perfect. BUT! when I power the Fuze off and start it WITH the card, it cannot start. It loads for a couple of seconds and then gives me a scary artifact weird picture and powers down.

edit: ah I forgot. If I only have like one album on the card, the player CAN boot, it is only a problem when it is full!

Any chance someone know how to fix this?

Thanks!

So I just installed the newest Version of Rockbox (dev).

Now I get this error message:

Data abort at 3080061C
FSR 0x8
(domain 0, fault
address 0xE58030CC
pc: 3080061C sp: 300AB41C
bt end.

can anyone make anything out of this?

edit: okay I think it's just the card. it's also making troubles with the computer, loosing files etc. I guess I will need to buy a better one ...

Thanks
