there was a blackout while I was writing some datas on my HDD, and now My WD 2TB doesn’t work anymore, from the Disk Management in Windows 7, i can see that the hdd it’s not allocated (the capacity is 0 gb) and if i try to allocate it an error windows will appear (it says that there is a problem with the I/O)
what i like to know is how I can format the HDD (i can delete the files in the HDD)
You can use chkdsk to try to fix the partition. Otherwise, you can partition and format with Windows or Test and erase the drive with Data Lifeguard Diagnostics.
