After managing to rescue my dad's old Classic II, I've been meaning to get around to replacing the failing SCSI drive in the machine with an SCSI2SD. Problem is, I'd like to do it with a clone of the original hard drive, as it has some interesting stuff I would like to keep around. My current thinking is that I can buy some SCSI to USB adapter, plug it into a Linux box, and do a dd clone of the whole drive, then somehow plop that onto the SD card. Or maybe, is there a way to use the SCSI2SD itself as an SCSI adapter through its USB port? Basically what's the best way to go about cloning an SCSI drive to an SD card?

Cloning old SCSI drive to SD for SCSI2SD

Hello
To sum things up, you first need to find a way to plug the SCSI2SD and the old hard drive to your Classic II simultaneously. You need an old hard drive enclosure (can be costly and perhaps you don't have the desk space for it...) or one of these adapters. Either way, you're going to need a cable to connect it to the Mac. Be careful as most HD enclosures use a Centronics SCSI connector. The Mac doesn't. You'd need a C50 to DB25 adapter if you choose to go that way. If you go for the small PCB adapter (which is what I recommend), get this cable (not a centronics cable...) and a male/male gender changer. The only problem is that those cables are also used for serial and not all pins are connected when that's the case. It might be worth checking with the seller before you buy it.
Once the hardware part is covered, you have a few options to do the backup...
1/ Just copy the HD's contents over to a new partition on the SCSI2SD. The system folder may need to be blessed (common issue, google it for more info...).
2/ Use Shrinkwrap (you can install that on the SCSI2SD. I have a partition ready with System 7.5 and Shrinkwrap on an SD card. It's become my backup station.) and create a disk image of the old hard drive. You can use disk copy 6 too but I've had really good results with Shrinkwrap. This later enables you to transfer the image from the SD card to your modern computer and use it with mini vMac or Basilisk II. I covered this method here.
Good luck!
