    Cannot online volume to format flash drive


    Hello,

    I recently burned an ISO onto my flash drive to install Linux onto another PC. Now I'm done and ready to format the drive. It won't show up in Computer or anything like I that, so I went to Disk Management to see if I could find it and try to format it. In doing so, it created the volume, but failed to format as the volume is offline. I entered DISKPART to try and online the volume, but it simply responds "DiskPart could not online the selected volume."

    Can someone explain to me what's going on or what I'm doing wrong? How do I get my flash drive working again?

    Thanks much!

    Hey rct2guy,
    It might just be a drive letter conflict, so try changing the Drive Letter for the Flash Drive in Disk Management.

    With the flash drive inserted, open a Command Prompt (Admin) or Powershell (Admin). Run:

    diskpart
    list disk
    select disk # <-replace # with the actual number of the flash drive
    clean <- this will erase the disk selected above - make sure it is the flash drive!
    create part pri
    format fs=fat32 quick
    active
    assign
    exit
    exit

    Hopefully that straightens it out.

    Ah, it took me ages to find this. My disk was "online" but the volume for whatever reason was "offline" so I couldn't move forward with the reformatting process. These instructions sorted that out. Appreciate it.
