I am having difficulties connecting an external hard drive, which my Sony Vaio will not recognise. Connecting it via a USB cable results in the following error message:"Power Surge on Hub Port: A USB device has exceeded the power limits of a hub port." I am able to reset the port, but unable to connectthe external hard drive. Suggestions please.
USB Port can supply only 500 MA, which may not be sufficient to run your HD. You may need expernal power source for your HD, if it allows to do so.
Sorry external power source
The device is equipped with an external power supply; nevertheless the error continues to occur.Any suggestions?
What exactly are you connecting to?USB port 1 direct off motherboard2. port on PCI card3. port on hub plugged into port on boardShould work direct offf mother board or you may need a powered hub
I am trying to connect a 300Gg external hard drive in a safeCom case to my Sony Vaio via the UBB 1 connector.
External cases are usually USB2 although should run off a USB1.1 port but slower.I surgest if you have a spare PCI slot you buy a USB2 card and plug the drive into that it should solve your power problem and upgrade the speed at the same time (Approx £10)
If you put this drive in the case, the Drive should be set to Master. Then in XP look in Disc Management to set a drive letter
I'll give this a try.
also connect the drive direct to PC USB port
Forgot to add, check the connectors are the correct way round on the drive
