Are you really sure that it is a DB-15, and not a DB-19? As you may know, both the Apple IIs and early Macintoshes use a DB-19 connector for the external drive(s) port. And I have read that in 1984 and later a number of hard disks were made for this port, because it was the only practical way to add a hard disk to either the //c or the Mac 128/512 (without opening its case, of course). References to this kind of hard disks can be found in "The Apple //c Book" (published 1984) and "The Apple Macintosh Book" (published 1986). The two connectors on the drive may point to a daisy-chain capable drive.
Anyway, if the connectors are DB-19, you can chek to see if pins 1, 2, 3 and 4 are grounded. If they are, you can be pretty sure that it is a disk port. If it isn't a DB-19, or it hasn't these pins binded to ground, I really have no idea on what kind of hard disk it is. Maybe it will need a propetary disk controller card to work...
