As the formats changed I moved from zip disks at the time rather than put it off till I had lost my machine with said drive.
If you didn't move with the changes you have to find your new exits.
I was a big scsi guy back in the day. I still have stacks of media on ORB disks & DAT data tapes ..and the hardware that can read them is easy to find at any flea market, but getting them into gear from this century is posing a challenge. Here's my question - should I try to find adapters from SCSI to USB or Firewire and software to read from these devices, or should I just frankenstein an old machine to connect these devices to and use it as a medium - to talk to ancient devices & use them as network shares? And if I do this, would I be better off using, say Win95 or Linux? These old devices were used on WFW & Netware nets in the mid 90s. I figure I could put a closet full of DDR2 DATs onto a handful of DVDRs. Same for the Zip, Jaz & Orb disks.
