    Buy a Mac. You will be shocked at how wonderful it is. It is certainly worth the extra cash. Imagine a life without error messages and virus attacks.

    Because your not using a Mac. The reason why i don’t use windows is exactly that ^, random problems. There is NO reason why it wouldn’t work under those conditions. But i will try to help you anyway. Try a different USB port and also try formatting it to FAT32. It may be broken but excellent luck. Oh and exchange to Mac!!

    Hi:

    When Windows 7 start up. The first thing it does; is to send out a request to your Drive Manager and question Hey buddy what drives do we have and the drive manager tell it, this what we got Drive C: Drive D : and Drive A ( if got that ( a Floppy disk drive) ). when you connected it to the USB port The USB bus should send a Request to Windows and say we got a New piece of Hardware and windows 7 should send a request to the New hardware asking what are you? and if your new drive has a plug and load program – it send a request to Windows 7 saying I’m a New disk drive and I want to load my drivers ( the interfacing program that enable windows 7 and the New drive to talk to each other) into you and please place my Id in your Disk Manager So I will recognize via my roundabout input code. And Windows will either say “go ahead” or No, because I don’t recognize you HP code but sometime Windows 7 will recognize it – only with you restarted your again with the USB still plug in to it in both your drive and it. than it will recognize your external hard drive. to initialize the drive program

    I hope this helps

    It may be orphaned hardware, and 7 doesn’t support it.

    Go to HP’s site and see if they have updated firmware.
