That connector is called SCA, SCA-80 or SCA-2, adapters are easily available through ebay and such.

LVD is NOT compatible to Single Ended per se. But 95%+ of the devices are LVD/SE, thus SE compatible. When using them as SE drives, you need to provide proper termination. Do NOT use an LVD terminator as it won't work in SE mode. Any (active) SE terminator will do, LVD/SE ones, too. Make sure that at least one device provides termpower to the bus.

I've never had a reason to force LVD/SE drives to SE by jumper. They very reliably detect the SE bus (all return pins are GND), so any SE device connected to an LVD bus will limit all devices to SE mode. (edit: slightly rephrased)

The adapter looks fine.

Set the ID jumpers on the SCA adapter, more practical that way. I wouldn't use the Force SE jumper in case I wanted to reuse the drive on LVD later, otherwise it could throw the whole bus to SE mode. You don't need it, honestly.
