[Desire Q&A, Help & Troubleshooting] ppurcell:
I have a 32GB uSD Card Class 6. I partition in Recovery (RA) with 512 Swap, 1920 ext2 (or 3 or 4 tried all) and remaining FAT32. If I use the old 8GB Class 4 card with 100MB Swap, 512MB EXT4 and remainder FAT32, it works fine.

I get the error "Bad magic number in super-block while trying to open /dev/block/mmcblk0p2" when I try to upgrade from EXT2 to 4 and when I wipe DALVIK Cache. I tried mini partition with the same results. I have formatted card with NTFS and copied a 17GB movie file and it plays ok. Reformat it as above and back to same old error. Can copy files into FAT32 partition (<2gb files that is) and see them. Here is a RECOVERY.log of the partition, upgrade and then Dalvik cache wipe. Please help

What does this all mean. I had a dream of a 32 GB storage with plenty of songs and media on my HTC Desire
