Summary
RMPrepUSB is a Windows 32-bit utility for partitioning and formatting drives, with particular attention to USB drives. It can install or repair boot code, clear write-protect or read-only flags, and add bootloaders such as MSDOS, FreeDOS, Syslinux, and grub4dos. Drive checks include testing reported capacity and running sequential read and write speed tests. A built-in 32-bit QEMU MBR emulator can boot from a USB drive with full write access. The utility can back up an entire USB drive, its partitions, or selected portions to an image file, then restore from an image. Its download also includes the RMPartUSB.exe command-line utility, and a portable copy can run from an extracted folder without installation. The product page describes MBR drive creation for drives under 2 TB and says GPT support is minimal. It is freeware for private and public non-commercial use; commercial use and redistribution require permission or licensing. The download page lists v2.1.746 dated 2022-05-29 and calls v2.2.4 an experimental beta that may contain bugs.
