Solved Errors when copying from External Drive

Post by zeckdude on Thu Nov 13, 2008 5:22 am

Hello all,

I am trying to copy some files from an external hard drive to another drive. At first I have to wait for a while as it says "Preparing to copy..." and then it copies very slowly. After copying a few(different number every time I try) files, it gives me the following message:
"Cannot copy file: Cannot read from the source file or disk."

I have also received the following message a few times while trying to copy:
"Cannot Copy [filename]: The request could not be performed because of an I/O device error."

I am receiving these errors when I either copy to an internal Hard Drive or external Hard Drive.

I ran a check disk, and it came back with the following message "Windows was unable to complete the disk check."

I am very confused as I can access the files on the external drive, but it runs slowly as I try to open or navigate through the external drive. Also, I am confused, because it lets me copy some of the files, but then at some point gives me a error message.

What can I do to copy files from the external hard drive?

I hope you can help me as I have some very important files on the external drive, which I ofcourse didn't backup. Also, please let me know if there are other options available to me such as recovery services or recovery programs if I cannot solve it on my own with your help.

Thank you in advance!!!

Upon putting my external drive into a USB port on the back of the computer, I noticed it's ALOT faster than the USB port in the front of the computer where I had it plugged in so far. It also copies correctly now with no error messages. I now see that BOTH of my front USB ports are not working correctly and the error messages were due to that.

How can I fix the front USB ports so they work correctly?

I don't think you can fix it. This is most probably caused by shortage of power through your USB port.

My external hardisks also won't work properly when I use a USB cable extender or by connecting it to the front.

Make sure the wiring from the front ports are still connected and intact on the mobo.

If you have more than two ports on the front of the case, you may actually have USB hub(s) that have muliple ports connected to one port on the mboard, which may be causing issues.

Go to device manager and see if there are any issues (yellow or red exclamation marks) with any of the USB controllers.

even if there are no conflicts you might want to try updating the drivers under USB Enhanced Host Controller.
