If HDtoolbox gives you a negative or a very small disk size, you are just over the limit. Reduce the number of cylinders to get below the limit.
Hint: you can connect a HDD of any size, but you can only use the first 4GB of it.
4 gb are 4096 mb, 4194304 kb and 4294967296 bytes.
And 8388608 blocks of 512 bytes each.
