As far as I know, the Ultra5 and Ultra10 onboard ide controllers don't support
disks that large. I don't know what the maximum size is, but a Blade 100 has an
UDMA66 (or is it UDMA100?) controller, and that specification supports disks up
to 137 GB.
As the Blade 100 is meant as an upgrade to an Ultra5 or Ultra 10, I think that
the upper bound is at most 137 GB. However, there have been reports of using a
disk larger than 137 GB in a Blade 100, and getting the first 137 GB to work.
More than 137 GB is impossible with the Blade 100 onboard controller though.
The upper limit of an Ultra 5 is at least 20 GB, as I have one running with a 20
GB disk, and I can use it's full capacity.
An alternative could be installing a pci ide controller that does support disks
of 200 GB, or installing a usb controller and using a usb to ide enclosure. Note
that in the former case, it could be that it is not possible to use the ide disk
as boot disk; in the latter case it is very sure that you won't be able to use
the ide disk as a boot disk.
Hope this helps
