Hi, thanks for your hint; the issue is still open and I have no clue what to do next although your answer helped a little bit. But how or where do I have to install the check ? Could you please detail your idea a little bit more ? I tried "fsck.ext3 -p /dev/mmvblk0p1" on the line before "mount -a ..." in rcS but this did not work: => "fsck.ext3: No such file or directory while trying to open /dev/mmcblk0p1" Just fyi in the syslog I found these lines: Apr 21 11:50:11 [..] [ 1.854104] EXT3-fs: barriers not enabled Apr 21 11:50:11 [..] [12.856129] kjournald starting. Commit interval 5 seconds Apr 21 11:50:11 [..] [12.856223] EXT3-fs (mmcblk0p1): warning: maximal mount count reached, running e2fsck is recommended Apr 21 11:50:11 [..] [13.091387] EXT3-fs (mmcblk0p1): using internal journal Apr 21 11:50:11 [..] [13.091398] EXT3-fs (mmcblk0p1): recovery complete Apr 21 11:50:11 [..] [13.093917] EXT3-fs (mmcblk0p1): mounted filesystem with ordered data mode What does all this mean in detail - especially "recovery complete" ? Another question in this context: do you think a (automatic) fsck is needed at all with ext3 ?
