    Fsck on usb external drives ?

    I have a couple of external drives formatted to ext4,after some use I can see this message
    Code:
     EXT4-fs (sdc1): warning: maximal mount count reached, running e2fsck is recommended
    every time I attach one of them:do I have to run a manual fsck after unmounting it,or can I safely ignore the warning ?
    Being an external drive,it obviously gets mounted/unmounted kinda frequently,so theorically I'll have to run this check pretty often.

    The other one is actually worse,it's a 3.5" WD drive with its own power supply,and lately it occasionally doesn't get auto-mounted when I plug it in,the message in syslog looks like this
    Code:
     ubuntu-kernel: [ 3618.190700] EXT4-fs (sdd2): error count: 8
     ubuntu-kernel: [ 3618.190705] EXT4-fs (sdc2): initial error at 1366215273: __ext4_get_inode_loc:4814: inode 11143320: block 44564649
     ubuntu-kernel: [ 3618.190711] EXT4-fs (sdc2): last error at 1366215527: __ext4_get_inode_loc:4814: inode 9836246: block 39321997
    does this mean that there is some actual filesystem damage on this drive,or can it be a sketchy power adapter,as I've read somewhere?

    Re: Fsck on usb external drives ?

    Thanks,that will take care of the first message I suppose (the disk is new and there would be no point in checking it so often),but what does the second message actually mean ?

    This other disk is not so new and that line
    Code:
    EXT4-fs (sdd2): error count: 8
    has got me worrying:can that be actual filesytem damage on that partition,and what am I supposed to do about it ?

    Is fsck -f going to fix this ?
