It is. That 720GB is in units of 1000's, while the 670 GiB is in units of 1024's. As drives get bigger, the difference in manufacturer advertised sizes (measured in 1000s) is getting more noticable when compared to GB measured in 1024s. So, the above is telling you your 720GB is really 670GiB, and I'm guessing you formatted it ext3 and the journal is taking ~32mb. That 627+33 = 660G...and you probably have 10G in reserved blocks. ---------------------------------------------------------------------- Jon Lewis *jlewis@lewis.org*| I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________ - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
