I'm trying to write proprietary commands to a GY-2120 DTF drive, and
to do this I need Sony's SCSITOOL.EXE software, which was released
in the mid '90s and ran on Windows95 (I believe).
Does anyone have this lying around somewhere?
If not, does anyone have the SCSI command manual for these devices?
If I knew the CDBs required to issue the "RECOVER" command I could
live without their tool.

Does anyone have this lying around somewhere?I can't help with that tool, but maybe with the command, see below.
If not, does anyone have the SCSI command manual for these devices?According to this flyer the GY-2120 should be a SCSI2 device: <https://www.broadcaststore.com/pdf/model/666445/sony_gy2120.pdf>

The SCSI2 specification does not list a RECOVER command for sequential-access devices. But there is a command RECOVER BUFFERED DATA defined in section 10.2.8:
******************************************************************************
10.2.8 RECOVER BUFFERED DATA command
The RECOVER BUFFERED DATA command (see table 184) is used to recover
data that has been transferred to the target's buffer but has not been successfully written to the medium. It is normally used to recover from error or exception conditions that make it impossible to write the
buffered data to the medium. One or more RECOVER BUFFERED DATA commands
may be required to recover all unwritten buffered data.
