Dynamic disk import error - Help!

[vsrdan]

I reinstalled XP in a computer which has 4 HD's (one of them is the boot drive). After installation, I cannot import the other 3 HD's (all dynamic) in the Disk Management console. They all were physically unplugged when I installed XP. I tried them (individually) on a different computer, same thing. I can't import "foreign disks". What should I do? Use "diskpart"?

Thanks for all the suggestions in advance!
