SAM FLEX Debian FSCK ISSUE

I have Debian up and running on SAM, however, at startup today I had a partition error which started fsck to automatically repair, however, fsck failed to repair the problem and asked me to input my root password to run fsck manually or hit ctrl-d to break the shell. Here lies the problem, the system will not recognise the keyboard at this stage, hence I cannot do anything to repair the partition.

Hopefully, I can get around this by running the install disk and formatting the offending partition but this is NOT good news if the system drive gets an error. Any ideas?
