My computer does not recognize new hard drive
I have a new external multimedia hard drive and my computer does not recognize it. I am using Windows XP. It appears on the task bar but the only option there is "safely remove device". I tried the suggestions offered to right click on "my computer" - go to computer management and there it is - it says Disk 1 and has a "busy"sign over it. Written "unknown" and in the box next to it is written "unallocated". Another suggestion suggested going through the Control Panel to administrative tools and there to Disk Management - only Disk management does not show up there.
A very frustrated lady with a brand new toy that doesn't work. Thank you in advance for any help.
