When i plug my hard drive up it blinks once but the computer doesnt pull it up

Try NOT connecting your camera to your computer.

The best way to transfer pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use the EOS Utility or any other photo management program, such as Picasa.

sounds like someone might have plugged to big of a voltage cord into it. take it apart and hope for a fuse??

sounds like the powerboard bit is knackered on the case try taking the drive out the case and buying a hd caddy sata 2 usb

These drives are known for lunching the power supply within the unit itself. Depending on you PC configuration, you may wish to do the same as I did when mine went. The drive itself is a standard 7200 sata drive. If your motherboard has sata capability, and/or a spare sata connection, you can slave the drive into your pc, and end of problem.

You are recommed to change you serial cable to Harddrive it would get back in working ..

How do you have it connected to your PC? USB or Firewire? try plugging it in to different slots or try plugging it in on another computer to further isolate the problem. some external drives requires power adapter to work so make sure that you're using the power adapter if it comes with the device. if not, there might be something wrong with the device specially if it was working before

No it draws power through the USB port. Try it on another computer, if it doesnt show there either, then you may have a bad device.

I had the same thing occur to my I/O Magic 250 GB USB drive a couple of days ago. I did an online chat with I/O Magic tech support and the guy said you can RMA (return) it if it's in warrantee, but otherwise too bad. Mine is out of warrantee. Since the enclosure contains an ordinary hard drive inside, just carefully peel off the little metal plate at the back of the unit, undo the two screws and slide out the drive. The are two plugs and four screws to free the drive. To get your data back once you've got the drive out, you've got three choices: buy a new enclosure ($20+), buy a toaster ($50) (it's like an enclusre, but you just pop a drive into the top, like bread into a toaster), or open up your computer and connect the drive directly as any other. Oh and don't buy another I/O Magic product again.

Data recovery usually will cost about 2000 - 3500. i may be able to help as long as the platters aren't physically damaged. Send me the drive at your cost. I will pull all data and return data on burned dvds I keep the drive. If i can't retrieve data then i will return drive to you at my cost. [email protected]

I have been using this hard disk for about 6 months now. It stopped working. The power and the usb cable are connected. I use Windows Xp and it doesnt read it. And for some reason most of the time when i open 'my computer' and the hard disk usb cable is plugged in 'my computer' stops responding !! However the 'safely remove disk' icon comes on the task bar and i can remove it from there. But i cant read it from explorer. The light on the HD keeps blinking. It reads my friends HD and flash drive. Please help me.
