SD card robustness?
I run debian on my beagleboard with the root filesystem on a SD card.
Specifically a "sandisk for Wii" 2GB card. Recently the area surrounding
the start of the ext3 root partition went bad nuking the superblock and
thereby rendering the system unbootable.
I managed to clone the card with gnu ddrescue and repair the filesystem
using an alternate superblock so afaict I didn't really lose anything
and I've replaced it with a sandisk 4GB SDHC card so the system is back up.
However i'm worried it might happen again. Has anyone else seen similar
issues running linux with root on SD card. Should I be buying something
special and/or using a different filesystem? SD cards are supposed to
have built in wear leveling right?
