Ok so I have encountered a problem with my 64gb memory card. Anytime I connect to my computer, it prompts me to format disk. Formatting through this option fails and formatting through chkdsk fails. in addition to this, my computer sees the memory card in properties as 0 bytes used and 0 bytes free, In disk management, my memory card comes up as 30mb. All options are grayed out that you would normally get from right clicking. I tried using recovery software and they all detected my memory card as being a "raw drive". I think from my observation that a partition is missing. What can I do to resolve this or have I reached the point of no return.
