    Compact Flash write cycle

    I believe there are quite a number of embedded systems that run on compact flash. I have an application that does quite a number of logging, so far i can only think of disable the swap partition and enable it when the memory is low, mount only /var as rw and others as ro.

    Is there any other ways to reduce the chances of a compact flash from wearing out? I wanna solve this because i have 2 defected compact flash most likely due to wearing out (exceeded write cycles).

    These are the messages that i get from dmesg :

    1) EXT3-fs error (device sdc1): ext3_get_inode_loc: unable to read inode block - inode=32065, block=65540

    2) end_request: I/O error, dev sdc, sector 4049
    EXT3-fs error (device sdc1): ext3_find_entry: reading directory #11 offset 0

    3) EXT3-fs error (device sdc2): ext3_journal_start_sb: Detected aborted journal

    4) EXT3-fs error (device sdc1): ext3_readdir: directory #19 contains a hole at offset 0

    5) Buffer I/O error on device sdc, logical block 0
