The filesystem (and files) on my memory cards get frequently corrupted. I have a Sandisk 1 GB and Kingston 2 GB MMCmobile. I format a card, copy it full of files, insert into 770, use the system for a week or two (without removing the card or creating any new files) and then some garbled files start appearing and I start getting IO errors. Both cards. I swapped the Kingston to a new one, but the same thing happens. I do use a swap file, so certainly there are writes to the memcard, but I doubt a new card wears out in a week because of it. And it's not just that the filesystem is corrupted: reading /dev/sda using dd fails with IO errors on some blocks. I seem to be able to "fix" it by writing zeroed blocks over the bad ones (using dd) a couple of times and the IO errors disappear throughout /dev/sda. The card starts failing again as described above eventually. So, is this a feature of 770 or is my unit special? I use IT2006 (the first), with 2 GB memcard support but not high-speed mmc patched kernels.
