I tried every possible master/slave/cable select/none position for the
jumper, and the system always freezes at the Windows logo screen. Any other
ideas?
First, is the LS-120 recognized in your Bios?
Second, and you must have quick eyes, is the LS-120 recognized during the
boot process?
Third, go to hardware and device manager. Click on your computer and then
click on check for new hardware.
Fourth, when you boot does the green light on the LS-120 flicker at all?
You may have your power supply connected improperly. Yellow is on the
outside.
On all the computers that I have used the LS-120s are listed as floppy
drives because I do not install any software for them.
