In the case of an optical drive, for instance, the device would need ATAPI support for an "eject media" command. The ATAPI command interface that is built into both the PATA and SATA specifications has support for devices that provide functionality beyond that required just by standard hard disks.

However, their manual makes no mention of this either. I see that in the example picture they have both ACD and Master jumpered. I googled it and came up with ATAPI CD-ROM but without any explanation. However, I did find this Startech IDE2SAT2 one which has jumper settings for Master, Slave, Cable Select, and ACD.

(I suppose with no jumper maybe some of the latter ones default to cable select but I have no way of confirming that for most of them, since either there are no online manuals or else their manuals don't mention it at all.) I presume I will need to use Cable Select for any new drive. It turns out many such adapters have no jumpers at all, or else jumpers for Master and Slave, but not Cable Select. The existing DVD-RW drive in the machine is set to cable select, so I presume I would need to do the same on the SATA to IDE adapter. So, I'm thinking of buying a SATA to IDE adapter to convert the SATA Blu-ray drive to an IDE drive.
(There is an AHCI patch, but for this model it does not work for SATA optical drives.) Unfortunately, it does not work in Windows 10, because the Mac emulates IDE for this and does not support AHCI. So I ran a SATA cable to the optical drive bay and it works fine in OS X. Unfortunately, the optical drive bays in the machine support only IDE / PATA, and not SATA. One of the things I added was a SATA Blu-ray drive. I'm in the midst of upgrading an ancient Mac Pro.
