Description
Requests new partition size to be:
- Maximum: 49% of drive size if at least 59% of drive is free, leaving at least 10% free
- The greater of:
- Current free space of drive less 10% of total drive size
- 49% of free space of drive
- 20 GB minimum
Repartitioning will probably fail on dynamic and dynamic disks, but should work on both GPT and MBR.
If you change the drive name (line 22) or drive letter (line 23), please also update the relevance to match.
