    This is an actual problem, this meen's that the usb device, got "unpluged" or stoped responding, and got "replugged", this is where the SDE1 got detected at first (bootup usualy) then when this gets unplugged and plugged back in, it need to alocate a new SD. this is where the SDF1 comes into play.
    I Dont have a very big knowledge over this, but I would suggest that hotplug could be faulty if this occur at random occasions, AND mabye a faulty USB port... Also, if you using a LAPTOP this could also be an issue if you run under the battery, aspi "mabye" turns some "useless" devices off for battery saving... Again I must advise you that these are all hypotetic since Im not an expert, but it should give you / other idea on the actual problem.

    I am not a 100% sure about this, slap me if I'm wrong,... FAT is a very old filesystem and mabye it only support 8char fileName + 3 char extention... I remember having a computer like this, but it's been to long I havent used FAT... sorry if that confused you. Here an option tho. FAT isnt that of a good filesystem. FAT32 is way better, and if you dont need windows support, go for something like reifers or etx3 they both integrate journalizing (like NTFS does) and is fragmentation free! which is the GREATEST advantage over any other filesystem... In order to do that, you WILL have to format the drive to another filesystem. If you need more information on that just ask.

    Hope this helps

    Thanks for the help. The drive works now.
    The problem I think was, that I made a mistake when I formatted the drive.
    After I formatted the drive on another windows computer, I could unmount and it works perfectly.
