How to recover a unallocated partition with bitlocker encryption

My computer is running windows 7. It have 5 partition: C (windows), D, E, F, I. D: and F: partition is encrypted with bitlocker. I tried to shrink D for 2GB free volume wih diskmgmt in windows 7. After that, F: drive disappear on windows but It still appear on diskmgmt as unlocated partition. I tried to used Active recovery partition but It cannot solve the problem. Please tell me how?
Many thanks,

Hello John,

Could you post a screenshot of your Disk Management window showing all of your HDD's layout to help us better understand what options you may have?

John,

You should be able to delete the 75.11GB free space partition on the far right to make it unallocated space. Afterwards, you could either create a new partition with the unallocated space, or extend the D: partition into it.

Thank you for quick reply. I cant delete the partition because "delete partition" is disable. I wonder that what happen with data on the partition, is it deleted after delete the partition?

John,

See if you may be able to use the delete volume override command at step 5 in METHOD TWO in the tutorial below to delete the "free space" volume.

Partition or Volume - Delete

If not, then see if the free MiniTool Partition Wizard Home Edition program may be able to.

Well, I'm not sure if you may be able to recover anything on the HDD since it was encrypted with bitlocker. You might see if creating and using a ubuntu live CD may be able to recover your files off the partition.

You could right click on the "Free space" partition, and click on the New Simple Volume option to restore the partition. Afterwards, you could use your Active Recovery Partition program or a program like Recuva to try and recover any data from it.
