The second drive may not be hanging the buss, but it is causing problems
reading anything except track 0. Adding a second drive, especialy
adding one to the second ide chain, will not change the geomitry of the
first drive. But adding a drive with bad electronics can cause problems
with data corruption when reading from another drive. From the problems
described, it looks like attempts to read anything except track 0 does
not work with the second drive installed. This is why the first stage
of LILO works, and why he can read the partition table, but is unable to
access anything else on the drive.
The only time LILO has problems when adding another drive is if you
change the LBA mode, or if you have SCSI drives in the system. Adding
an IDE drive to a system that boots on a SCSI drive can cause problems.
Normaly, I would suspect bad cabling before bad electronics, except for
the fact that he tried the drive on both the primary and secondary
chain, and the fact that the drive came from a "dead" system.
