Presumably, that is a 720K drive (subject to what the extra controller
is). IBM sold internal and external 720Ks for the XT. To do it their
way, you need PC-DOS 3.20 or newer, and need to do a DRIVER.SYS in
CONFIG.SYS. But you could also use a 720K with certain OEM
(NON-IBM) versions of MS-DOS 2.11.

And the PC-JX (not available in U.S.) was available with 720K drives.

Do you mean that it is NOT connected to the same controller as the
5.25" drive?

Which model Seagate? It is likely to be an aftermarket drive.
