It can, but not safely.

dosemu normally provides a replacement for the DOS file system to safely 
use the Linux file system in a reasonably compatible manner.

You can enable direct hardware access in dosemu.conf for specific I/O 
ranges, etc, and run dosemu with root privileges to punch a hole through 
the kernel security & moderation layers, but you should think twice 
about doing so.

If you want to repair a HDD with DOS-based tools, make a bootable CD 
with fredos on it and use that to run them. Look at 'UNetbootin' for 
such support.

Regards,
Paul
