Software recommendation: hard disk management with a good Macrorit Partition Expert

We often need to manage our hard drives, such as deleting hidden partitions and rebuilding them in order to free up space, completely deleting data on hard drive partitions for privacy reasons, masking bad sectors on hard drives, and so on. Such operations can now be easily done with the help of Macrorit Partition Expert (hereinafter referred to as MPE), a free and graphical partitioning software.

One-click deletion of hidden partitions

All brand-name machines contain hidden partitions, which take up a lot of hard disk space. If the hidden partition does not work, for example, I have already reinstalled the system and installed the PE system on my computer by myself, I can now free up this part of the space. Although the system comes with the appropriate partitioning tools – Diskpart command line and Disk Management component, but the former is a command line interface is not suitable for ordinary users, while the latter has limited functions, such as the inability to operate on hidden partitions (there are many brand-name machines come with recovery partitions) (Figure 1).


Figure 1 disk management can not operate on the recovery partition

Now with the help of MPE (download at you can easily free up this space, I am using the “Portable edition” portable version of it, after downloading and unpacking it, it will automatically identify all the mounted hard disks on the machine after starting MPE. MPE will automatically identify all the mounted hard drives on the machine, and then we can manage the partitions in a variety of ways according to our needs (Figure 2).

Tip: Partition management is an extremely dangerous operation, so be sure to make a backup of your data and back up your important files to a safe place before doing so.

First find the hard disk that needs to be freed up, then find the recovery partition in the list of partitions on the right (the word “Recovery” will be displayed under “Status” after it), click on ” Operations→delete volume” in the left pane, delete it and then rebuild the partition. Because operations on partitions are very dangerous, and all dangerous operations in MPE, you will see the operations you have performed in “Opending Operations” after execution, and you can click “Undo” at any time before committing changes. You can click “Undo” at any time before committing changes (unlike Windows 10 components, which cannot be undone, Figure 3).


Figure 3 Deleting partitions

Tip: Deleting the hidden partition must be a good trade-off beforehand, because most brand-name machines have built-in genuine operating systems, which are generally saved in a specific hidden partition, so if you delete it, you will not be able to do the operation of restoring the original factory settings to the computer.

Delete sensitive data completely

There are more and more private files saved on everyone’s computer, and for those files that are not used, if they are simply deleted or formatted, some people with ulterior motives can easily retrieve these files through data recovery software. So for some important private files, if you want to delete them completely, you can delete them completely with the help of “Wipe Unallocated Space” provided by MPE.

First, delete the partition where the private files are stored in MPE, then select the deleted space, click “Operations→Wipe Unallocated Space” in the left pane, and in the opened window, select “Fill Sectors Zero” (for higher security, you can select “DoD 5220.28-STD”). This MPE will fill this unallocated space with a large amount of zero-byte data, and after completing the above operation, right-click on the partition and select “Create volume” (create partition), which effectively prevents the recovery software from ever finding the deleted data again (Figure 4). Of course, technology is always a double-edged sword, after such an operation, is even you can not recover the data.

One-click repair of various bad sectors

The former is caused by the fact that the checksum information (ECC) on the disk track does not match up with the data and servo information on the track, usually due to the wrong operation of some programs. The latter is a real bad sector that needs to be shielded to better protect the data on the hard disk.

We can use MPE to scan and repair logical bad sectors on the drive, for example, many of them are located on the system partition of the drive, which can be scanned directly (Windows 10 comes with components that can only be scanned before rebooting and entering the system again). Select the hard drive to be scanned as above, then select the partition to be scanned in its partition list, click on “Operations→Check volume” in the left pane, activate the scanning component and perform the scan and recovery (Figure 5).


Figure 5 Detecting partitions

For the detection of physical bad sectors, you can use its Surface Test tool, as above, after selecting the scanned hard disk, click “Operations→Surface Test” in the left pane to activate the scan, so that MPE will scan all areas of the entire hard disk, and the areas where bad sectors are found will be marked in red (Figure 6) The areas where bad sectors are found will be marked in red (Figure 6).


Figure 6 Bad channel scan

If a bad channel is found, it is recommended to scan the hard drive where the bad channel was found again in order to more easily mark the actual location of the bad channel. Taking my hard drive as an example, the first bad channel was found when the scan was 95% complete (judging by the “Complete” completion value when the bad channel was found). The hard drive is divided into three partitions C (41.63GB), D (60GB) and E (47.42GB) for a total of 160GB (the exact value is 149.1GB), so it corresponds to the bad channel in the E partition (about 149.1*0.95=141.64GB around the location of the hard drive). After activating the scan component again, click on “Sacn area” and select the initial scan location in the pop-up window to start at around 140GB (Area size reserved “9269” MB or so, more space reserved for the starting amount. By pulling the slider, you can see the starting position of the scan), and scan again to determine the location of the bad channel (Figure 7).


Now we can separate about 10GB of space at the back of the drive depending on the location of the bad channel. As above, follow the instructions to delete the E partition containing the bad channel, then right click on the deleted partition and select “Create volume”, in the pop-up window, set the value of “Unallocate space after” to In the pop-up window, set the value of “Unallocate space after” to “10240” MB, that is, set aside about 10 GB of space at the back (the area where the bad partition is located) without partitioning. This way, the bad channel will be in this unpartitioned space, which can avoid frequent reads causing the bad channel to spread, and finally click “Commit” to submit and save (Figure 8).


Of course MPE has many more features, such as the ability to convert MBR to GPT disks, swap primary and logical partitions without loss (no data loss), 4K alignment, etc., which can help us solve many hard drive problems.
