I recently bought a 500 gig IDE drive for my external hard drive enclosure. When I tried to copy some files over to it I keep getting an error of Error 0x8007045D There might be a problem with the I/O device. I've Googled, and looked everywhere, and I don't know how to get rid of this. I need this data backed up bad so I can reformat. I am currently running Windows Visa Ultimate Thanks for the help!
Does the enclosure support that drive? Many IDE drive enclosures only support up to 400GB drives and do not support larger models due to power concerns.
I've had endless trouble with usb hard drive enclosures, is it usb? If it has firewire connectivity and your pc does too, check if it works like that. Before replacing the HD I would check if it is running fine without errors by plugging it in as you would normally internally. Transfer a couple of files to it, small ones and big ones (over 1gb if you have any) then check if these files can then be accessed (or played back if they are video) from the new drive without errors. Only COPY and paste the files you will be using to test it, DO NOT CUT AND PASTE as you may lose those files if the hard disk is faulty. Then do a checkdisk (http://malektips.com/windows_xp_0006.html), make sure you "Scan for and attempt recovery of bad sectors". If it's all good I would try another hard drive enclosure as I've found these to just not work sometimes with particular systems. Or sometimes certain enclosures don't work with certain brands of hd.
I've had more stuff go wrong when new than break over periods of years, go figure. It happens sometimes. I agree on the USB issue, hence why I usually ask to try different cable, port etc.
