Create a new partition on my C:\

[Bp_]

Just a quick question.

My C: drive is 70G and I want to create a new parition from this of 10G so I will have C: of 60 G and E: of 10G.

If I do this with the Director suite, will it format my C: drive ?
or it will only reformat my new partition of 10G and leave my C:\ drive untouch.

Thanks,

You can do this with DD.

First, I always recommend creating a backup of your drive before making partition changes. The software is designed to be safe and not cause any data loss, but sometimes things go wrong. At the very least, backup any important files you wouldn't want to lose.

Use DD to shrink the C: partition smaller by 10GB. Then create the new partition in the unallocated space. Your C: partition will just be smaller and shouldn't be affected in any other way.

You should note that if you have any bad sectors in the C: partition, then DD won't let you resize it.

Thanks for this quick answer.

I will backup my important file since my environment isn't too old.

I can just run a chkdsk to see if I got some bad sector ?

You'd have to run chkdsk /r to check the entire partition. This can take a while since it checks the whole drive. If you start it from Windows, Windows will have to reboot to run the program since you're checking the system partition.

You can check before the resize if you want. I think the reason DD doesn't want to resize if there are bad sectors is because it might result in data loss.

If no bad sectors are flagged right now, then DD should work okay. If you run chkdsk and it finds any bad sectors then it won't let you resize. It's your call, of course, but if it were me, I'd just backup and then do the resize and not bother with running chkdsk.
