Maxtor basic hard drive cannot be seen by my computer

Hi,
I have the MAxtor Basic 1TB hard drive with data of about 500gb. I was in the process of backing up on McAfee Online Back when all of a sudden the hard drive started squeaking and now cannot be recognised by any of my computers.

I have changed cables, changed computers but no avail It is not seen by any of the data recovery software as well.

On the Disk Management it shows aS DISK 5 Unknown and when right click it tells me to initialise it and when I say yest it says...I/O Device Error.

When I go into the Device Managerit is listed under Disk Drives and says Device Working Properly.

Any help as to how I can get it up and running or have I lost all my information...omg?

Please help.

Many Thanks.
 
From personal experience I have had a hdd (hard disk drive) do the same thing. After trying it in multiple PCs and two different Macs, it was hosed. Keep in mind... "the failure rate of hard drives is 100%, it's not a matter of IF your hard drive will fail, but when..." My advise: if the data on that hdd is that important, send it away for data recovery. It's not cheap, but can you put a price on the value of your data?!

Here is a list of data recovery companies that either I, or my customers have had success with. Sorry for the problem with the drive, but hopefully this will help. Take care!
