Use DVD-RAM like external HFS SCSI HDDs on 68k Macs, possible?

[dreunion61]

Computer: Quadra 840av
Drive: Panasonic LF-D201 in external SCSI case.

Formatting with the usual utilities is not possible. Tried on 7.6 and 8.1. The System detects an empty drive but when trying the format it comes with an write protect error on the OS utility. The drive is detected as 0B.

Others like FW HD Toolkit, Lido and drive7 just don't detect the inserted DVD-RAM at all. They detect it as a CD-ROM drive. Also tried DVD-RAM TuneUp, the drive isn't detected there.

When burning an HFS CD-ROM disc image to a DVD-RAM, it does work fine like any other CD-ROM. But I want to use DVD-RAM discs like Zip floppies or HDDs. Is that possible?

EDIT: Forgot to mention, I also tried to create an HFS image in Cider Press 2 and then burned it directly to the DVD-RAM via ImgBurn. I also tried to directly dd it to the DVD-RAM like an HDD image. Didn't also work.

DVDRAM support did not come to Mac until 8.6, which is after the point where 68k Macs were no longer supported (MacOS 8.1 was the last version that booted on 68k). There have been efforts to get later versions of MacOS to boot on 68k, but DVDRAM support was supplied by a driver extension and I doubt they created it as a fat binary.

I see but what is he talking about?

Removable media, which is better

I've always known about the zip drive. I remember how useful it was. How we had 2 drives die to the "click of death". The whole nine yards. Long story short, I've been using an new ide 250mb drive and a scsi 100mb drive to transfer files between my ibm system and mac. However, this weekend...

Apparently he likes to use DVD-RAM on 68k macs?
