I reformatted both as single ext3 partitions to get round the annoying FAT-32 4GB limit on individual file sizes. The WD is used for compressed daily overnight backups which started to fail as soon as a compressed backup hit 4GB, which is when *it* got reformatted. I didn't mess round with the Formac. It got reformatted as soon as I plugged it in for the first time. The Formac is used for weekly offline backup via rsync and is fast (8-12 mins per backed up computer). Both 'just work' and, because I'm not using vfat, the file permissions don't get messed up and the file ownership isn't lost. Martin
