Windows 7: Best software for to recover data in a hdd portable?

i have a portable western digital hdd but the problem is that doesn't shows up in computer as a letter only i can see it in disk management as disk 1 as unallocated space a black bar and not initialized and when i click in the space that it has with right click only appears offline not online
so i want to know the best software for to recover all the data that i have there i need it urgently doesn't matter if the software is free or i have to buy it
or what to do for to have it working normally as it was
please tell me thanks xxx

Hello ruby and welcome to Seven Forums. Since you can see the Western Digital in disk management, you might be able to assign a drive letter by using Option One in this tutorial.

Drive Letter - Add, Change, or Remove in Windows 7

If that works as I hope it will you should be able to open the WD and retrieve the data via start > computer > new drive letter. You might also be able to use a free tool called Recuva.

Recuva - Recovery from damaged or formatted disks

thanks for welcome me to the forum

referring to my problem
i have tried what you suggested to assign a letter to the drive but those
options are not available
when i connect the drive a message appears that says
you must initialize a disk before logical disk manager access it
i click ok but then a message appears and says
the device is not ready
and the option online doesn't appear only offline and i dont want to lose my data
thanks in advanced
