Gurce Isikyildiz returns with a practical demonstration on formatting floppy disks for the MEGA65. His latest video focuses on the differences between double density (DD) and high density (HD) disks and the challenges each type presents when preparing them for use.
While working on a game project with his daughter, Gurce encountered problems with HD disks. He explains that these disks often require additional preparation, including covering the density hole with tape in the correct position. The MEGA65’s drive sensor only detects tape when it is placed on the bottom side, which is a common point of confusion. Once this step is done properly, HD disks can work, though Gurce advises that DD disks remain the better option for long-term reliability and for projects that may be released physically.
The video continues with a step-by-step demonstration of formatting using the MEGA65 floppy test utility, originally created by Gardners. Gurce shows how to perform a complete disk wipe, format, and verification to confirm the absence of bad sectors. He also discusses the importance of thorough testing, since old disks may still contain unreliable areas.
For copying large amounts of data, Gurce highlights a faster method than BASIC copy routines: using community-developed floppy tools that can write D81 images directly to disks. This process reduces copying time from fifteen minutes down to just a few, making it far more practical when preparing multiple floppies.
Throughout the video, Gurce shares useful tips, including workarounds for failed sector writes and his own small BASIC helper program to streamline copying individual files when needed. The content makes it clear that patience and process matter when working with legacy media.
For anyone preparing disks on a MEGA65, this video offers valuable guidance and illustrates the quirks of floppy formatting in action.
