_Simplest_ would be:

1. Create partitions on the big drive (call it /dev/hdB) equal in size or
    slightly larger than the ones on existing drive (call it /dev/hdA).
2. Add more partitions to fill up the drive.
3. Do for each partition /dev/hdAN:
     dd if=/dev/hdAN of=/dev/hdBN bs=128k
4. Do for each additional partition /dev/hdBM:
     mkfs -t whatever /dev/hdBM
5. Reinstall the bootloader on /dev/hdB
6. Rewire/rejumper, or arrange to have the BIOS boot from /dev/hdB.

Done!

Be sure _not_ to copy over /dev/hdA4 (if that's the big one that holds
extended partitions). Also, if you have four primaries on /dev/hdA, the
last one will have to become a partition-within-a-partition (I think
"extended" is the word), if you want to use the additional space on
/dev/hdB.
