The discussion is about removable USB HD used for data backup or data
transfer and whether to use ext2 or ext3 file system.

Replying to and quoting only the above paragraph takes it out of
contexts and changes its meaning.  

The solutions to power outage is to buy and install a UPS.

To find out how much space is used you can look up the ext3
specification and do the calculations or format the drive with both ext2
and ext3 then note the difference in space left.

Please read the entire thread for more details.
