Here's my setup:

I have a 300gb drive.

C: (Primary - OS drive) - 160gb
D: (Primary - Recovery) - 10gb
F: (Primary - Files) - 60gb
G: (Logical - Files) - 50gb
H: (Logical - Files) - 10gb
I: (Logical - Files) - 10gb

Now I want to shrink my F: partition. That's not a problem.

But then, I can't re-allocate this unallocated space to one of my logical partition...
Anyone knows why..?
Or how I can avoid this problem..?

Thanks.

hoppl4, hello. The "logical" refers to logical drives, not partitions. The one, single partition which all logical drives live in is called the extended partition. So you have 4 partitions, which is the max for Windows with basic disks -- 3 primary partitions and an extended partition.

I'm going to assume that your partitions are in order as they would appear in the drive map of Disk Management (diskmgmt.msc). When you shrink the F partition (3rd primary partition), that creates unallocated space after F and before the extended partition. Using the Disk Management utility, you can't "expand" a partition to the left because that changes the starting point and it requires the partition to be moved to the left.

To do the operation that you describe, you should use a Partition Manager. There are a few free ones: Easus Partition Master, Paragon Partition Manager Express, and Partition Wizard. Only the last one supports 64-bit Windows in the free version.

It's very important to backup the data on the partitions that are going to be altered in any way. There is always a risk that something could go wrong during partition operations and data recovery would be very difficult and/or expensive.
