When drive turned on blue light appears then red light comes on & computer cant see hard drive

Sorry to hear that your drive is having trouble. When you start the drive, do you hear it turning?
Is this a external that you can remove the hard drive? You may try to power down the external, power it back up and shut down your computer. The conect the external and turn the computer on.

Let me know if you can hear the driver turning and it you can connect after going thru the process above.

Take out the hard disk from your case and put it inside a desktop- if there's still some life left in it it will appear in My Computer. If it doesn't appears even there then it's dead for sure and all the data on it is lost.

it might have been dropped, if so it could have bent the little read pin inside causing it to not be able to function correctly, those little harddrives cant take a very big hit

Remove battery and power

Remove memory in lower socket, the one on the system board and try reboot with just power cord. May have bad socket

Most likely problem is a physical problem with the hard drive, but could be plenty of other things. Best bet is to back up your information (if possible) and do a fresh windows install, if you continue to get the message after a clean windows install, your hard drive is not stable, and has a problem.

there is no solution

My nx2 is working again after having the "red light/blue light/I/O Error" problem. I just:

1. turned off my computer
2.unplugged the HD,
3. took out the HD from the enclosure and plugged it back into the enclosure,
4.started up my computer without the HD being plugged in
5. after my computer had been on for a minute, I plugged the HD in and my computer recognized it and had the proper mixture of red and blue light coming from the HD, indicating it's working properly.

Good luck!

Plug it into another computer if possible, clear ALL files on it.
You must of been sending something to it when you flicked the switch, they would normally go off straight away.

(Backup on the other computer first)

If this does not work then you may want to see if you can see a usb stick in your USB ports. If you can it's a fault with the harddrive, nothing else you can do.

Put your ear to the drive and verify if it is making any strange low level sounds. Check to make sure the usb connection wasnt affected. YOu wont need a driver as it appears to be hardware related. Either the enclosure or drive may be failing.
