This is the input line, not an output (it's data line from disk drive to
the computer). And it is shared between the internal and external drive.

Perhaps a stronger output buffer could be placed at the internal drive
so that it would drive the line stronger. But it would require modifying
the drive, and still it doesn't explain why Bo's computer works.

Or maybe some kind of external buffering device between the cable and
the computer, but since this is a shared input which can be also driven
by the internal drive, this would be nontrivial.
