Thanks andy, I tried re-partitioning my HD before using 3rd party tool, an Im afraid that I may loose my data (but I do have backups on other drive), and thankfully, the tool works, no data loose.
but it was different, I use to add more space to an extended partition.

your share may help me in the future. thanks.

What I did not see is a BIG warning not to try create a new partition when there are already 4 primary partitions on the disk. I see a lot of people that end up with dynamic partitions and then do not know what to do.

If you want more than 4 partitions then you must use DISKPART utility to create extended volume that can holds any number of logical partitions as there are available drive letters;

I feel that would be the best solution. A Description of the Diskpart Command-Line Utility

Yeah, that's one way. But you still have to make sure that you do not have more than 3 primaries before you create the extended.

why use a commandline utility, when you can use a GUI ?
"Disk Manager" (diskmgmt.msc) works for creating logical partitions too.
