To set the allocation unit size for a drive, such as the C drive, which is typically defaulted to 4KB during installation, you can adjust it using the Disk Management tool in Windows. However, for running a Windows VM with a storage size of 32KB, you might need to create a virtual hard disk (VHD) with a different sector size.
Here's a step-by-step guide to adjust the allocation unit size for a physical drive:
- Press
Win + Rto open the Run dialog box. - Type
diskmgmt.mscand press Enter to open Disk Management. - Right-click the drive you want to modify and select
Properties. - Go to the
Volumestab and clickAdvanced. - Under
Allocation unit size, select the desired size (usually 64KB or 128KB for larger drives). - Click
OKto save the changes.
For creating a VHD with a different sector size, you can use a tool like the Windows Disk Management console or third-party software like VirtualBox or VMware. The process varies depending on the tool you use, but generally, you'll create a new virtual hard disk, specify the VHD file location, and choose the desired sector size during the creation process.
