Sorry for you. I had this a lot with my IceFS tests which is why I wrote that everyone should be aware fo this filesystem. If it worked stable it would be a dream because in the beginning it is really fast and appears stable. I would like to use it as standard filesystem. But so far I cannot recommend it. I hope you can copy your files to another disc which is not IceFS formatted. It would be great if someone could fix the bugs in IceFS and IceDoctor but the author seems to be not working on it anymore for years now. I would not count on any update. Better go baxck to SFS and be on the safe side.
