I was trying to recover my pendrive as it was showing 0 bytes allocated space, and I came across some information about using the diskpart command to format it.
For the worse I selected a wrong volume and started the process; I selected my hard drive and typed in 'create partition primary'. Now I cannot see my drives except for the local disk: C, in which my OS is installed. :( Please help me; I have no prior knowledge about this, yet I've toiled my hands and now I am stuck ... the data is very important ...
Thanks in advance for your help!
