Hello there we have received Youre message. Hi there when disconnecting and removing the power it falls into one automatic lock. The hard disk is locked .The storage processor asks for a password and can give access to this hard disk. Also the inability to reach the complete folder from outside can have something with what you have filled in at the beginning of your installation. (Linux)) Due to a crash, sometimes one and the other can be approached so that this can not be repaired. You could use an additional program that is meant for this problem. You have ended up here with Firefox. The main folder is actually trapped in your hard disk. Maybe a program like file unlocker can help you. Finding such a program is not that difficult. Think of it as about the same as with Windows in number of thoughts. Greatings Firefox volunteer.
