This late afternoon I decided to do a bit of re-partitioning on my large external harddisk and make some more room on the FAT32-partition to make the data on it (mostly recorded broadcast videos) available for my LCD TV which only accepts FAT32 partitions.
Everything went well in the beginning, the large 800GB partition was shrinked within two hours (yes, it takes a bit over USB) and the moving of the following partitions took only a few minutes more. But the enlargement of the FAT32 partition from 100 to 300GB is now already taking about six hours and I am getting a bit nervous...
I'll let it run overnight now and hope that it'll be finished in the morning. But I don't know how I should proceed, if it's still busy when I get up.
