The 630 requires "Internal HD Format", which is specific to the 630. Although a hacked Drive Setup from OS 8 should be able to do the job.
There are two types of limits involved with the 630. The first is an IDE/ATA limit. ATA-2 only supports up to 132 GB, which really means 120 GB (nobody made any drives between 120 and 132 GB.) Any drive under that should be recognized just fine. Any drive larger than that, and you would give up any capacity over 132 GB, and would require that the drive have a "132 CAP" or similarly-named jumper set on it. (Some newer drives don't have this, and would not work at all.)
The second limit is, as SilValPir mentions, is software. Depending on the version of the MacOS, your partition size may be limited. You can 'get around' this by just using multiple partitions. One problem is that you have to use HFS for the boot partition on a 68040, although data partitions can be HFS+ on a 68040 system. (So you could have OS 8.1 on a 2 GB HFS partition, and the rest of the drive as one big HFS+ partition for apps and data.)
