Most likely you’ve hit the MBR partition-table limit that pointed to: the disk is using Master Boot Record and all four partition-table entries are already used (hidden OEM/recovery partitions count too). That’s why Disk Management refuses to turn the 70 GB of unallocated space into a new volume. (To : shrinking C: does not split the physical disk — you still have one 320 GB drive, now divided into used partitions plus unallocated space.)

Quick checks

Windows key + R -> diskmgmt.msc

Look at the left (Disk 0) -> right‑click -> Properties -> Volumes tab -> Partition style (shows MBR or GPT). For a command‑line view:

cmd (Run as Administrator)
diskpart
list disk
select disk 0
list partition

What to do next (safe, ordered options)

  • Back up first. If the disk has an OEM recovery partition you might want to use the vendor utility to create recovery media before touching or deleting it.
  • If the disk is MBR and already has four primary entries: either remove an unneeded partition (after backing it up) and create an extended partition to host logical drives, or use a partition utility that can convert a primary to a logical/extended partition without data loss.
  • Converting the disk to GPT removes the 4‑partition limit but requires UEFI firmware to boot Windows; do not convert a Windows system disk to GPT unless you understand UEFI boot implications.
  • Converting to a Dynamic disk will allow more volumes but has portability and compatibility drawbacks.

Always back up the system and any recovery media before making partition changes.

So do you still have the 320Gb disk ? Or have you now got a 250Gb and a 70Gb ?

Maybe you just hit the 4 partition limit for primary partition.
Check 'Disk Management' again to make sure. I'm suppose it's going to be like this

Partition #1 - System Reserve (100 MB)
Partition #2 - Windows
Partition #3 - New Partition
Partition #4 - Recovery Partition (usually hidden)
