This is one of the most severe errors that can occur in a hard drive extern or any other unit data storage. You Need to format the disk in drive: H Before you CAN use it.
Basically this Errors May we not let you access the data hard disk stored, pictures, movie, applications, documents, Music or anything else stored on that disk. The only normal options are "Format disk"- Ie completely losing data stored on the external hard drive, or"Cancel"- But this option does not really delight us because we could not access the hard disk drive.
Doing this tutorial data recovery following a personal experience. In my script I was talking about a hard drive extern Toshiba a 1 TB that I used both Mac OS X as well as a laptop computer Windows. It seems as if it is formatted NTFSAnd the hard disk is connected when on OS X when on Windows, there is a chance that at one point the Mac will not see it again, and again Windows the "surprise" above appears.
How to recover data from an external hard drive, stick / flash drive, or memory card in case of "You need to format the disk in drive: H before you can use it"
First of all you need to know that a 100% safe solution does not exist, but with a recovery program it's possible. The condition is that at the moment a message appears " You Need to format the disk in drive: H Before you CAN use it " do not click the option "Format disk"
In my case, my help-tool was my great help Data Recovery Wizard Professional 8.5. Although cost nearly $ 67 if you have important data recovered, the investment is worth it. For me it was worth it. And this is not a tutorial in which to be paid EaseUS. Simply was the first time I found a solution to my fully recover data on a hard disk with errors.
The steps you need to use are very simple. Install the application Data Recovery Wizard Professional, Connect the external hard drive to your PC, and when the message "You Need to format the disk in drive: H Before you CAN use it", click the button "Cancel". Open the application Data Recovery Wizard Professional, select the hard diskURL from which you want to recover data and switch scanning. This process can take from a few minutes to dozens of hoursDepending on the volume of data stored on the drive. At the end of scanning somewhere to the left of the application or to appear folders and files recovered which you can select and export then on another hard disk. Good luck! :)
