So here goes,

Slackware 10.1 on hd1 with three partitions:
/
/var
swap

Has worked fine.

I Installed another (hd2) that was my old XP hdd. It had two ntfs partitions when it was in use. I wanted to be able to view all the existing data on this drive. I slapped it in, did the mkdir and mounted it just fine.

But, there is a directory listed that has a name that I cant cd to. it is a square, I think hex value 0xDB. How can I get into this directory? Will I be able to view the second partition without losing the data on it? Do I need to know the old partition sizes and update it with fdisk?

A note: I am working only from the console.

try
cd nameuptostrangechar*

That is, exchange strange char with a ?-mark or a *.
You could alsa use TAB to expand directory name.

The problem is that the entire directory name is this one character. I'll try various cd's with ?'s though.

Which shell do you use?
Could you send us what 'ls' produce?
The man page for ls givs this: Show us what 'ls -b' gives.
You could also try 'ls --quote-name --quoting-style=escape'
After reading man rm, try this: 'rm -i *'
