Eassos PartitionGuru is a basic partition manager with a particular focus on data recovery.

The program has options to create, format, hide or delete partitions, for instance, but it's not so great at manipulating them later. There's an option to resize a partition, for instance, but you can't move space from one partition to another, or convert its type.

PartitionGuru has plenty of useful features elsewhere, though. You can protect your system by backing up a drive's partition table, ready for easy restoration later, while there are options to clone an individual partition or an entire hard drive.

And if things still go wrong then there are options to recover individual files or entire partitions.

If you need more power, though, it may also be worth considering PartitionGuru Professional ($69.95), which is much more capable. It can recover files on discs with non 512-byte sector sizes, for instance; supports GPT discs greater than 2TB in size; can recover data and partitions on USB, GPT, and virtual disks, and has many other more advanced features (the Eassos site has the full list).

Version 4.9.2 adds these new features (see changelog for more):

- Display and read files in EXT4 partition.
- Hex editor supports Go To Sector operations related to EXT4 file system.
- Hex editor supports Data Template related to EXT4 file system.
- Support FDD disk or image which is formatted to EXT4.
- Add support displaying data allocation table for EXT4 partition.


The free version of PartitionGuru has a lot of restrictions, but if the recovery functions work on your system then it could be very useful.
