Debian :: Mounting External Drives - Unexpected Inconsistency

This question is an extension of previous posts in relation to my removable drives. I have an external usb/ide drives and cowon iAduio7 music player. The former is always connected and latter occasionally. The first drive to be recognized gets allocated /dev/sdc1 and /dev/hdd respectively. Until ten days ago I would simply mount them manually after each boot. Recently I added them to my fstab file. It's fine only for this error message on boot.

Code:
/dev/sdc1 unexpected inconsistency.
fsck died with exit status 4
failed (code 4)
Control-D to continue

I found the following on the net
Code:
If a device is not being mounted during boot, it may be b/c the driver for that device has not been loaded yet at the time that /etc/fstab is read (and thus the device is not active yet and doesn't get mounted). If you want to make sure it gets mounted during boot, you may need to take a look at the boot sequence for your distro and make changes as needed. Another thing you could try is adding a "mount" command of your own to one of your boot scripts. Most distros provide a file with a name like "rc.local" which gets executed late in the boot process and can be used to add your own custom commands to execute during boot. Firstly I want to know which script do you edit and does that mean I have to re-edit the fstab after creating the script.?

Here is my fstab:
Code:
[sudo] password for siawacsh:
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/sdd /home/siawacsh/cowon vfat defaults
/dev/sdc1 /home/siawacsh/myhome ext3 defaults 0 3

/dev/sdb1 none swap sw 0 0
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto 0 0
siawacsh@debian:~$
Remember sdc1 is the external drive, and sdd the music player.

I have attached the removable drives to directories mhyome and cowon.
