My external hard drive is unallocated  

whs said:

Try to run these commands from an elevated command prompt. Maybe it helps:

Diskpart
List disk
Select disk n (where n is the number that was given for your disk in List disk)
Clean
Exit

Why it cleared my other drives (D & E). Those information are as valuable as my life

What should I do nooooowwwww??

Please

hmm.... It would seem that diskpart is unable to see your external drive - presuming that you had it connected - and you were trying to run clean command on your system disk.

True, it is very hard for me too to imagine that just an inadvertent act of pulling out the USB connection running the external drive can result in such a catastrophic failure, but when the manufacturer's diagnostic utility itself cannot repair it and fails it, I don't think there is any hope.

Sometimes we do, do things hoping against hope for a miracle to happen and it does happen sometimes. In these cases also it is really not a miracle but something which we did not understand and hence we could not resolve. In other words it is just a reflection of our own insufficient knowledge.We still do not know a thousand things.

Coming to diskpart, you could still try to write zeros onto the external HDD with the WD utility. It tries to do the samething, a Quick Erase being equivalent to clean and Full Erase a cleanall with no scope of erroneously selecting your system drive for you can see which drive you are selecting.

I think it's completely destroyed!

Attachment 329397

The software that I used for checking errors was AVG TuneUp Utilities.



Do you think this software did that?

Your attachment links are invalid and do not show.

I don't know anything about AVG TuneUp, but those types of programs generally add nothing worthwhile.

I'm still confused. how can it still remember my password.
