I have several 3M DC 2120 Mini Data Cartridge Tapes. They are about 10 years old and have data on them. I'd like to know where to go to get the data downloaded to a CD or DVD. Does anybody provide that service?
Well perhaps someone here will have what you need or know some person or company that does. But my point is that if you expect to get lucky you're going to have to tell us what software you used as well as what hardware.
As I recall, the software is "Colorado" something or another, perhaps "Colorado Backup". I still have the pc with the drive that runs these tapes, but I don't know how to transfer the tape contents to CD or DVD. I thought it would be easier to find somebody to do it.
If you've still got the PC then just use it to restore the files to an external USB hard drive or flash memory stick. If the PC doesn't have any USB connectors then you can get a PCI-to-USB adapter card for $15 to $20. Once you've got it on a USB device you can plug it into another computer with a DVD burner to burn the files to a DVD.
Even if you don't have a DVD burner of your own (they're also very cheap BTW), you'll have a lot easier time finding someone who can burn stuff from a USB device than from a tape cartridge.
