My Toshiba external hard drive powers up but my Toshiba laptop doesn't read it. The blue powr light is on and the rive makes a clicking noise. HELP!

You can't. When you hear the clicking noise every time it attempts to read, the sound you hear are the read/write heads striking against the edge of the enclosure. The drive has most likely failed. The only thing you can try is to open up the case and remove the drive and directly connect to your desktop computer. Another thing that sometimes works is to wrap the drive in plastic and place in the freezer for an hour, then connect it. IF it starts working, quickly save what data you can off of it because it will fail again when it warms up. I don't think that usually works with head failure, but give it a try.

Try another usb cable if that works. But if nothing, make sure if your hard drive can be found in device manager and see if it has a correct capacity. If both doesn't work at all, you have to remove the hard drive to it's case and insert into the pc directly but that might void your warranty.

Mother board hard drive controller may be bad requiring replacement of motherboard. Re format hard drive.I would remove hard rive and install it into my external drive module and connect it to another computer then exercise a hard drive repair program.

It sounds as though your issue is one of in adequate power. Do both the external HDD have their own power source, or are they powered through USB? if they are powered through USB it may be that as soon as the second drive spins up to transfer the files, it overwhelms the limited power of the laptop. You can try it with the laptop plugged in (though this may not provide it with more power than the battery) or by purchasing a usb hub with its own external power source so that it is not drawing power from the laptop, or purchase an external hard drive with its own power source
The other option is simpler and free, and its to copy the files first to your laptops own HDD, then unplug the source external hard drive, and then plug in the drive you want to copy to, then transfer the files from your laptops hard drive. This will of course take twice as long, but will cost you nothing.

Try taking it out of the casing and putting it into another external hard drive case. That is if you can, if its making a clicking noise it probably means your hard drive went bad or it means its not getting enough power to run make sure all the cords are hooked up tight. I had that problem once the hard drive wasn't getting enough power and i had to mess with it on the inside to make it have enough power. I'm not saying take the hard drive apart im saying take the casing off it and check the inside cords to see if they are tight enough. If that doesn't work leave a message and ill try to help again.

sounds like you are using the wrong power supply. Check the amp output on the power plug you plug into the wall make sure its the same as the amp input of your external harddrive

There is a (laptop-size) hard-drive inside the case, and that hard-drive is failing. As it spins, it generates those noises, like a dying dinosaur. If it still is under warranty, exercise the warranty, and replace it. If the warranty has expired, tough luck.

if you hear a constant clicking return the drive it is faulty.

I have that problem similiar to yours. My simple tech stopped working for like two years so i decided to open up my simple tech and removed my HD away from the old enclosure so I can try building my own external hard drive for the first time. I bought another new 3.5 enclosure, IDE/ATA for the old HD. I put it in the new enclosure and it worked!

It's the only solution you can have. No need to retrieve data or re-format your HD. You can leave it the way you like...if you wanna reformat it...up to you.

hello,
there is nothing to do. you should brought new one. there is no other way.
thanks
