I had installed ppc64 7.6.0. Now I have installed 8.1.0. Some images were stored on a USB stick. This USB stick I had inserted when I installed 8.1.0. Unfortunately this stick now seems to be reformatted: the type is no longer FAT32. I do not know which type it is: trying to mount with different types fails. The files 'syslog' and 'messages' show: sdb: [mac] sdb1 sdb2 sdb3 sdb4 sdb5 Are all images lost? winfried
