You don't describe what your USB massive storage is.  Or brand name and model.  Please supply that information.

Usually such a device is a hard disk in an external USB enclosure.
You first try the device in another USB port and also in another computer.  If no joy there then you take the drive out of the enclosure and attach it directly to another computer.  Most likely the drive will have a SATA interface so there is no trouble in connecting.  Usually a SATA interface but not always.  If the drive is recognised and can be accessed there, then the problem is in the enclosure.  If it can't be accessed then the problem is in the drive ...

Since it is just the backup disk, why do you need to recover any data? Just replace it with a working disk and backup again. Besides that you should always have more than one backup disk so you'll have further copies elsewhere.

Besides that use the manufacturer's diagnostic utility to tell you the external disk's status. It's results are usually also necessary to get your warranty replacement or to RMA the disk.

If the diagnostic tells you the disk is fine, and your OS you used with the disk was Windows, run a chkdsk /f /r on it's partition. This will repair any file-system corruptions and can also make your files readable again.

If all that fails, you can also scan the disk using Photorec for your data. It is included on the PCRepix LiveDVD:

Sometime there is no other way as to format USB device. you can use some free recovery tools. Important is that you put no data on it after you format it.

I use program called RECUVA.

It is very simple and affective.

Good luck.

If this is a single HDD external drive then you need to open the USB box and take the drive out. Connect the drive directly to any free SATA port on a PC. Then run on it GetDataBack from www.runtime.org
If there is more than one HDD in USB box then there is a RAID configuration. But if drives are ok you can use RAID Reconstructor from the same runtime.org

you can remove the disk from the usb case, and connect it directly to a sata cable
then check again; the i/o error can be caused by the cable or bridge (you tried another cable, yes?)
if you still have the I/O error - consider the disk hardware bad
if you need the data - use a recovery service - and expect to pay a couple hundred $$
here a good service : http://www.gillware.com/

***and regarding the asking for a FREE tool : i found that they don't work well, or are difficult to manipulate
the best recovery soft - not free is GDB  http://www.runtime.org/
