Hi,

My passport recently went from NTFS to RAW, and now it doesn’t show up when i plug it in to the computer.

I go to disk managent under Windows 7 an it shows up as Unallocated. I tried formatting but it always says failed to format; How can i fix it and or format it back to how it was in the beginning?

I bought it for PC so it was NTFS to start with.

Thanks in Advance!

That sounds like a data corruption problem, try using a data recovery program and then use the DLG to write zeros.
