SCP Version 1.98 No Index Pulse Found

[toml_12953]

I have two floppy drives attached to the SCP in my Win10 (64-bit) PC. One is a 3.5" 1.44Mb drive (drive 0) and one is a 5.25" 360K drive (Drive 1) I can create disk images and write to disks properly on drive 1 but when I try to use drive 0, I get No Index Pulse Found. Also, the light on drive 1 comes on when I access drive 0 but the light on drive 0 doesn't come on when I access drive 1. 

I'm using Hardware 1.1, Firmware 1.2 and SCP 1.98.
