There are also the superblocks and inodes, and probably other overhead. The default ext2 fs uses 1 inode for 3KB, and it looks like inodes are probably 128 bytes. I figure that at about 190 MB for a 4.5GB disk for inodes alone. -- Carl Johnson [EMAIL PROTECTED] -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
