I am developing an embedded Linux system that uses a compact flash card for storage. I have a little bit of data that needs to be stored to the card, but I do not want the entire disk to be mounted read/write.
So I have made two partitions on the CF card:
# fdisk -l /dev/sda
Disk /dev/sda: 261 MB, 261881856 bytes 16 heads, 32 sectors/track, 999 cylinders Units = cylinders of 512 * 512 = 262144 bytes
Device Boot Start End Blocks Id System /dev/sda1 1 62 15856 83 Linux /dev/sda2 * 63 999 239872 83 Linux
My question is this. If I write to the 16 meg read-write partition (/dev/sda1), will the writes be spread across the entire disk by the CF card's internal wear-leveling? Or will it spread the writes only within my 16-meg read-write partition?
