It looks like some of the versions of current update.1 candidates and joyrides have serious problems with flash drives and SD cards. This especially effects ext 3 use.
I first blamed cards, but even the good ones get clobbered.
Some additional info:
- As somebody else remarked, some of this appears to depend to some degree on the response time of the card or USB flash stick/adapter. Some cards I have do not work at all, but are fine in cameras an on OS X/WIN32.
- Problem go from just corrupting the boot or super block to a whole range of blocks not being written to flash resulting in an unrecoverable disk.
- This appears to be more of an issue with Joyride and update.1 candidate builds than the shipping version (656.)
I seemed to have less trouble, when running from the SD card directly. Booting and running from NAND seemed to create the issue with external cards.
I also noticed that power management did not seem to work/was disabled on 651/656 (this is documented) and when running from the SD card on other builds. It was enabled in a number of experimental builds running from NAND. Could it be the power management is interfering with the SD/USB flash writes?
