We have a TI Explorer LX which of late has started giving problems.
When the machine is booted, it fails to boot the File band.
It gives a message that reads as follows:

Nupi error: Disk unit 1, address : 5457
Device error: uncorrectable data error on read command

I suspect that there may be a bad spot on the "File partition" of
the disk unit 1.  Is there any way of confirming this?  I presume
that I would have to re-initialize the partition on the disk.
But before doing that I would like to find out what I would be
losing. i.e. what are the usual contents of the "File  partition"?
I know that the partition contains all the user directories.  I have
backups of the user directories on tape. I just want to make sure
that there are no system files on it, as I do not have any backups
of any system files on this partition.

Any help would be greatly appreciated.  Thanks in advance.
