Question about Computers & Internet
I purchased a Western Digital My Passport Essential Portable hard drive (320 GB) (model WD3200ME-01; order WDME3200TN). When I insert the USB cord into my 600M Inspiron Dell computer, the computer states the USB device has exceeded the power limits of its hub port. What does this mean and how do I fix it? Do I have to buy another type of external hard drive?
First, this is actually a good thing in a way. The reason is, it is actually telling you right up front that your USB bus is underpowered for this device. That's a huge improvement over issues caused by underpowered USB buses in the previous model computers. In those, we were left to having to figure out what the problem was when a USB device inexplicably stopped or didn't work.
What is happening is, your new external hard disk drive (HDD) is trying to run off of power taken from your laptop's USB "bus" (circuitry). This is OK for devices needing low power. But in the case of external hard disks, it's "iffy" whether there'll be enough power on the USB bus to support them. Particularly on laptop computers.
You need only attach an A/C adapter to your external hard disk drive (HDD) and you should be OK. If that is not an option, connect a **powered** USB hub to your laptop and plug the external HDD to the hub instead.
By "powered" I mean a USB hub that comes w/ an A/C adapter. In either case, using a powered USB hub or attaching an A/C adapter to your hard disk drive will remove the external hard disk's power load from your laptop's USB bus and provide sufficient power for the HDD to run.
You can find USB hubs at Newegg.com and lots of other online high tech stores. I like Newegg because their prices are competitive, their customer service is excellent and there're customer reviews of most of their products there as well.
