    Hi All,

    I'm having some issues with a USB HDD. I'd be grateful for any advice. It's a 320GB 2.5" HDD in a USB enclosure connected by a Y cable to two USB ports. I have two Windows 7 laptops - on one it works fine, but on the other it's not so good.

    When the drive is connected it appears in My Computer along with the drive letter and label. Trying to open it, however gets a "is not accessible. Access is denied" error. I've tried fiddling with the permissions as Google suggests with no luck. Also the "takeown" prompt in cmd seemed to work but changed nothing. I notice that I can access the files with command prompt, but that isn't ideal.

    I don't have enough space on my internal HDD to remove the files and reformat unfortunately.

    If anyone has any ideas that'd be great. Thanks,

    Try an external power supply. Those drives usually have a jack for connecting one. The power supplied by the laptop may be insufficient. You could also try using different USB ports if you have others, don't connect any other powered USB devices while using the drive, and make sure the laptop is using AC power rather than batteries.

    Some of the cheaper external, 2-USB-port cases seem to require more power than better ones. They work fine on desktops that have full USB power (not all do), but not so well on laptops. You would be better off all around with a powered drive.

    You should also be prepared to lose all the data on the external. They are the most unreliable of all storage media and fail often. Having no backup is playing against loaded dice.
