HDD not working due to I/O device error how to recover data?

I have a Toshiba 2TB External Hard Drive that all of a sudden tells me it needs to be formatted. All I did prior to this happening was restart my PC, the same way I do every day. I have more than 1 TB of files, pictures, videos and more on that drive with no backups of it anywhere and I really need everything back. I have read many threads similar to this one but others don't seem to have exactly the same problem that I do, in that when connected, my EHD constantly appears and then disappears in My Computer with a pop-up message. This means that no matter which data/partition/HD recovery software I use, it doesn't allow me to select the EHD as it keeps disappearing from the list. So basically, when it is plugged in, every 10 seconds or so it disappears and then reappears with this pop-up message: "You need to format the disk in drive F: before you can use it. Do you want to format it?" Obviously I don't want to format it as that means I lose all my data. Also, it uses USB 3.0 and is connected with a USB 3.0 cable into a USB 3.0 port.

A:

I/O(input/output) error sometimes could be a results of some connection issues. So, you can start with swapping the cables as well as changing the port. Trying the drive on another system will not hurt too.

When the hard disk not working, should not be easy to do the physical maintenance of the hard drive, be sure to have enough patience to find a solution. 2: The hard disk can not be identified, there are many hardware and software reasons, sometimes the file system or partition table damage, this situation, the direct use of data recovery software will be able to recover data; sometimes the motherboard configuration is damaged, the motherboard configuration reset to Factory settings, remove the motherboard battery and re-install the battery, in many cases this simple means will be able to solve the problem; some of the most common very simple problem, only need to clean up the computer parts of the dust can be; 3: Even if you have tried a variety of solutions, still can not solve the problem, do not be discouraged, have patience, still do not easily physical maintenance hard drive. 4: similar to the problems I mentioned earlier, and sometimes, the hard disk used for a long time, he just need to rest for some time, sometimes for another computer, only need more time to wait. It should be noted that some failures are caused by insufficient power supply 5: If in the end anyway can not solve the problem, do physical testing should be very cautious, at least in the detection of non-destructive means to be used. 6: A serious failure of the old hard drive, backup and recovery of important data, try not to continue to use.

Use "Full Scan" to recover raw files from Hard Drive, to recover files from Hard Drive if partitions show as "raw" or recover deleted files which can not be found with "undelete" and "unformat" and "recover partition" after showing an error,display as raw file system,unformatted,unknown partition,unpartitioned,needs to be formatted.
