Converted Hard Disk From Simple To Dynamic By Mistake... Need some info.

Okay I was trying to fix my flash drive that was corrupted and had started having write protected error. During trying to format, I tried different programs but to no avail. Then seeing the convert to Dynamic disk option on disk manager I clicked it but converted my C:/ Drive from simple to dynamic NTFS partition. All my files are here and everything works ok but I was wondering what are the advantages & disadvantages of a Dynamic Disk in comparision to a Simple Partition.
My specs HP 630 Notebook/Laptop, Windows 7 Home Premium x64 SP1, 2.27 GHz Intel i3 proccessor, 2GB DDR RAM.
Any knowledge citizens of RomU?

'Kay Thanks. Since everything is working fine I'll leave it is but if it BSODs randomly then I'll format. Thanks again.
