Multi-disk partition planning
Generate plans and risk notifications locally in the browser based on disk, GPT/MBR, UEFI/BIOS, system, and partition requirements, without writing to disk.
How to use the multi-disk partition planner
Multi-disk partition planning only calculates the input in the current browser; it does not access, write to, or format real disks.
Enter disk conditions
Enter the disk capacity, boot mode, partition table, and system requirements.
Generate plan
View partition order, capacity, file system recommendations, and unavailable space.
Manual review
Download or copy the plan; verify the hardware manual and backup strategy before actual installation.
Limitations and Notes
- The tool only generates a static plan; it does not read actual disks, create partitions, or execute installation commands.
- Vendor recovery partitions, encryption, arrays, 4Kn sectors, and multi-system boot rules require separate confirmation for the target device.
- Planning results do not constitute a data security guarantee; you must back up your data and verify with official tools before performing any partitioning operation.
FAQ
Will this modify my hard drive?
No, the page does not have permission to write to disk; it only outputs planning text.
Does it support UEFI and BIOS?
It can be used as an input condition for planning, but actual firmware behavior must still be verified on the target device.
Can it replace an installer?
No; it only helps organize partitioning plans and risks.
