Hey, I tried to format NTFS to FAT32 with Diskpart, but I get Virtual Disk Service error: The volume size is too big. I need to install this disk in my PS4, and the file system must be FAT32. Any help is appreciated.

Volume too big

Virtual disk service(VDS) is a set of application programming interfaces (APIs), which provide a single interface for managing disks and volumes. It contains the Disk Management snap-in, the DiskPart command-line tool, and the DiskRAID command-line tool (Diskraid.exe).

Reason for “The volume size is too big” error

Diskpart works as a Windows built-in tool, which can help you solve disk and partition problems. However, you may be bothered by Diskpart. When you try to format a hard drive larger than 32 GB to FAT32 file system, you will receive "Virtual Disk Service error: The volume size is too big".

NTFS and FAT32 are both popular file systems among computer users like all versions of Windows, Mac, Linux, or other game consoles etc. Both file systems have their own advantages and disadvantages. In some cases, computer users may change file system owing to specific needs.
