    I have a new Buffalo external portable 500GB HDD, and my compiter cant see it properly. When I go to AdMin Tools / Computer Management / Storage / Disk Management, I can see the disk. It is registering 467GB free, but it does not have a drive letter assigned to it and when I right click on it, all of the functions are greyed out. This means that I cant assign a drive letter or format the disk. Any ideas?

    Yeah, Re-Install or update your Anti-Virus software. I had the same problem last month with a new USB flash drive..

    If it shows in disk management its there, if its unused space You probably need to format it for Your pc to see it, this gives it a drive letter

    Maybe you need to add a partition first ? I dont have any empty disks to try this on, then when you have a partion(s) you can format. If you don't want the default drive letter, prob e:, you can choose one, the disk will then always be on that letter, but only for that pc

    How would antivirus software have anything to do with mass storage device drivers/event handling?

    No idea, I got two new memory sticks, neither would work, but older ones i had would work, I did some online research on the matter, came across some comments that suggest this solution, and tried it and it worked.

    Is everything (and i mean everything) completely greyed out. Surely the help option isn't for example. Can you go to properties?

    Do you have a live cd of some sort you can just try see if you have access on?
    Check in device manager that drivers are properly installed. (no little yellow question mark next to a disk)

    Most importantly, are you logged in as admin or restricted user.

    As unusual as it might sound i think I've seen this happen before on my own pc. Just turned the anti virus off and the drive mounted fine. I'm assuming they're badly implemented features that are supposed to block access to a drive if it detects a threat on it.
