Disk Refresher is a complete data erasure software produced by I-O DATA.
The Disk Refresher manual explains the purpose of the software, the supported Windows operating systems, and the required hardware environment. It provides step‑by‑step instructions for installing the program from CD‑ROM or floppy, creating erase media, and performing data deletion.
Safety notices, troubleshooting tips, and contact information for IO Data’s support center are included to help users avoid misuse and resolve common issues such as write errors or BIOS virus‑check conflicts. This manual is written in Japanese.
Check that the media’s interface matches one listed in the "Supported Media" section; unsupported interfaces will not work with Disk Refresher.
