Windows 7: WD Passport drive showing up with Unallocated in disc management

Hi every body
So it was working fine, i turned off my computer and went to bed, when turned it on the next morning the drive was no longer showing up so i checked disc management and it was in there as unallocated, the only options that are there when i right click are: Properties and help.
Im running Windows 7 ultimate x86 (32bit) on PC and the External Hard Drive is a Western Digital 1TB Model WD 070A USB device.

I followed this page : Western Digital drive showing up with Unallocated in disc management

but at the fifte screen check disk shows: "partition: Read error"
I enter search to find partition but after a long long time it finds nothing!
I dont know what to do

Thanks payman for putting out the error message you got on the fifth screen in Test Disk.

That was indeed a message that I had not anticipated when I wrote that post you had referred.

It would naturally mean that even Test Disk was unable to read your hard disk.

As far as I can see, your hard disk is beyond normal redemption/recovery and may require a professional Recovery if you want to recover any data.

However in all these cases, nothing is definite until proven and I may be wrong too .

Hold on to check whether other experts chipin with their brainwaves.

Doing test disc now too. Im having same problem with my ext hdrive. Any way to fix it if you dont mind losing the data? Or are they as good as paper weights??lol

Your query answered in the other thread MY EXT. HARD DRIVE WORKED GREAT UNTILL...help?!

Good Luck.

there may be light at the end of the tunnel. thanks)) will start on that now and keep u posted.
