Any fix for this problem?
I've made many test with a 4G SD.
If use it for boot qtopia from vfat and ext2 partions it work fine. Slowly but
If I start system from 2007.2 in flash the mounted SD partitions give me many
Sometime was mounted 1st partion, sometime all of than.
I've tried to access it in reading and writing and frequently I get I/O errors
On time was loose partition table (in suspend/resume session).
I've tried many partitions schemas (mixed FAT and ext2) but always I/O errors
I've reformatted in a unique partition with FAT and I've filled in it about
1GB of maps for tangogps from my PC.
The partition was mounted in /media/card and when tangogps start to read from
SD some file was read good and many other not.
The screen become full noised when SD is reading and get I/O errors.
After the read go to end the screen come back showing fine.
The 4GB SD with my PC work fine, no I/O errors.
The 512M SD in FR package always work very well.
The 4GB SD is a Apacer Micro SDHC 4GB Class 6.
