My guess is that the problem is here.  See the man page for mount(8).

For the ext3 partition you probably want to provide the "errors=continue"
mount option which will cause the kernel to ignore the error and continue in
r/w mode, however the ingetrity of your data is obviously at risk if you do
this.  The default behavior is set in the superblock and can be changed on
an unmounted drive using tune2fs.  It's probably set to "errors=remount-ro"
behavior if it's not explicitly set already in your /etc/fstab.

If this is happening on the vfat partition too, I'm not sure what the
options are there.
