USB hard drive problem

I have a USB hard drive attached to my SCO OSR6 machine I accidently powered it off while it was mounted and now the OS complains when you try to re-mount it and it appears that it is complaining because it has a new device number so it isn't at the original device location anymore. does anyone have an idea how I could fix this?

Is it in the exact same USB slot that it was in when it was configured?

While USB ports are supposed to be "invisable" in regards to OS systems, in fact they are referenced as individual ports. Moving the hd to another slot might cause to OS to see it as another drive.
