With 7.6 there's no problem booting off a drive that big.  While the
maximum volume size under System 6 and 7 is 2GB, with System 7.5, the limit
was raised to 4GB and System 7.5.2 and later increased that limit to 2TB.
However, the original HFS (not HFS+) only allows for 2^16 allocation
blocks, so a 2TB volume formatted as HFS would use 32 megabytes per file at
minimum, no matter how much data was in the file, which would be a big
waste of space.  Therefore while it would make sense to make a number of
smaller HFS partitions in 7.6 from an efficiency standpoint, it's not
required.

The bigger issue is formatting the drive, since some of the earlier
versions of Apple's Drive Setup only worked with certain drive models (it
would query the string), though with ResEdit it's not hard to work around
that.  More info on that here:
