Whenever i insert my external hard drive to the USB port of my desktop, the desktop flashes a message saying USB not recognize. And the hard drive does not work. i do not know to make it work..


The most common cause of this in my experience is not enough amperage available at the USB port. If you're using a front/top case port, try switching to one of the ones at the back of the case that is connected directly to the motherboard. If that doesn't work, you can use an externally powered USB hub, which usually solves the problem as long as the hub has a 2A or better power supply.

Hope this helps.

Hi.. i need help.. my external hdd transcend store jet 320gb have problem... when I conect HDD to pc blue led blink just one time and hdd stop working..


Check that the USB cable can provide enough power to the hdd. Check that the USB port is powered. Older USB slots may not have enough power to run larger external HDDs, there you may require separate power to be plugged into the hdd. Are you using the original USB cable provided with the external HDD?

My imation 320 gb 2.5 inch external hard disk cannot readby my laptop, but when i try it in some laptop my external is working there


Either the USB ports on your computer are not working
(try some other USB device in those ports to disprove this)
or the USB ports are supplying insufficient voltage/amperage to your Imation device,
such that it does not operate.

Internal 320 hard drive into external


If you got a USB casing for that, it would have come with a USB and power cable. Yes, power too!

Plug the power, and make sure you have a USB 2.0 hi-speed port. Also check "computer management" and check the hard disk works.

The computer no longer sees my 320 gb hard drive, do i need to download new drivers? if ao where do i find them. i store all my photo's and music on this hard drive


Possibilities:
1. dead USB port on your computer -- try another port
2. try a different USB cable
3. try your external drive on some other computer, to see if it works at all
4. open the casing, and separate the disk-drive from the USB-to-disk-drive adapter. Connect the disk-drive as a "slave" disk-drive, thus bypassing that adapter, to see if the adapter has failed, or if the disk-drive itself has failed
5. Google-search for a commercial "data recovery service" -- such companies can disassemble your disk-drive, and fix it, just long-enough to copy all your photos/music onto a brand-new disk-drive.

320 GB transcend external Hard dics is not at all detected


Hello,

First of all make sure that the USB port that you are using to connect it to your PC is a USB 2.0 port, and not USB 1.0.

Also if it came with an external power, connect it to the external power before putting on your PC.

This is because the voltage supplied by USB 1.0 is lower than that of USB 2.0 and therefore might not be enough to power up your USB Drive.

After making sure about this, power up your system, and plug the external drive, then Right-Click on my computer icon, select manage, then go to Disk Management Option.

On the Disk management option Page you should see ALL the drives installed on your system, including the hidden ones, so what you will just do is, try and locate the one representing your external drive, and right click on it. then select "Change Drive letter and Paths", and give the drive any new, unique letter (i.e alphabet) different from the ones already on your system, and click on OK.

This should make your external Drive to be detected automatically.

Hope this helps you out.
Goodluck!

No installation disc, but apparently i didnt need one


I bought the same product, I noticed that connecting the device to the USB ports at the back of the PC body and using shorter cable solved the problem, try each of the ports at the back of the PC.

External Hard Drive -- too much power for my USB port on my computer


Hi mhjohn

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.

If you have any more questions, comments, observations - anything at all, just let us know. We're here to help.

Thank you,
BJ @:)
