Why is this happening? The reason is due to the limitation of Windows Disk Management, to extend a volume you must meet some requirements. Here I will explain what you need:

A. There must be unallocated space or free space closely followed by a primary partition or logical partition.

To do this, you must delete the volume, but this means that all the stored information will be deleted so, it's advisable to make a backup.

Part 5: Other Suggestions to Clean up Recovery Drive D Windows 10

1) Remove the Recovery Drive Letter

When searching for the answers to the HP recovery drive being full on the internet, you will find advice to remove the drive letter of your HP recovery partition.

In Windows Disk Management, the recovery partition of a computer manufacturer has a drive letter, for example, HP assigns the letter "D" to this drive. Then right-click on the recovery partition, select "Change Drive Letter and Paths" to remove it.

When the recovery drive is almost full, you will probably choose to delete such a partition since you think it is not useful and takes up disk space. It is not so.

Recovery partition can be used to restore your system in the event of system issues, just like how we have mentioned in part one. So, this is not the best solution. But if you have a backup of this partition, this would be a good method.

3) Copy Partition to Another Disk

If you find there is not enough disk space to extend the partition by taking other free disk space or you decide to delete the recovery partition, you can choose to copy the recovery partition to another hard drive to resize the recovery partition during the copy process or make a backup.


Preventing the low-space Windows alert from appearing is a simple task and as you have noticed, it is a quick process to perform, however, the most effective solution is increasing the size of the Recovery Disk volume; it is important to remember that to carry out this process you will first need to eliminate the volume and this means losing all the information that is stored in it.
