Cheers guys...thanks for the help.
Ok, I changed the jumper to Master and tried all 4 USB ports on my laptop. I turned off all power settings I could but I dont quite know what this would do as the cd rom enclosure has its own power lead and transformer. I couldnt find anything to do with power settings for the USB...I may need a walkthru there. I also thried the microsoft support link but its not what my problem is...I tried the file anyway but it couldnt find the cd rom either. I also installed EVERY windows 7 update I could find. And I dont have another computer I can try it on until a few weeks away...
So its still not being found.
Heres exactly what happens from power off on the enclosure.
1 - I plug in the USB lead then turn on power to the enclosure.
2 - I quickly go to Start, Computer and I can see the CD Rom drive E next to my laptops dvd rom.
3 - The green bar at the top starts filling up from left to right and gets about half way then suddenly the CD Rom icon disappears and so does the green bar.
4 - It then flashes up under the laptops DVD Rom icon with a Local Disk drive E but only for a split second.
5 - Sometimes a balloon comes up saying installing device, then device successfully installed...but not every time.
And thats it....Im at a total loss and cant work it out.
Any more ideas?
