How to Fix a Bad Partitioned Hard Disk without Data Loss

As you know, a brand new hard disk cannot be used to save data until we partition it. To be specific, you need to initialize the disk to MBR or GPT, and then create partitions where data can reside. Nevertheless, without knowing future demands, you just partition the disk at random.

As a result, you may get a poorly partitioned hard disk, for example, some partitions are running out of space while other partitions are filled with free space. Well then, how to fix a bad partitioned disk when data have been saved? Next, we will give you some suggestions.

With this tool you can do some operations:

1. Create new partitions when there is unallocated space or free space.
2. Set a primary partition active.
3. Change drive letter and path for a specified partition.
4. Format a partition (it will result in data loss).
5. Extend a primary partition when there is contiguous unallocated space on the right or extend a logical drive when contiguous free space is located on the right.
6. Delete useless partitions.
