I think there might be some (alot of!) confusion here with respect to the disk size discussion... 1) One million bytes is ALWAYS equal to 1 Megabyte... let's not rewrite the math books to fit the problem! 2) If the drive were actually 810 Megabytes large instead of 810 Megabits then that would be equal to 8 * 810 * 10**6 = 6480 * 10**6 = 6480 Megabits (which btw = 6.48 Gigabits) If it's 810 Megabits, then that's equal to (810/8) * 10**6 = 101.25 Megabytes. Either way, it doesn't add up to 770 or 772... Just to clarify further, disc sizes are usually give in Megabytes. The abbreviations are supposed to be: MB = Megabytes and Mb = Megabits but these are often confused. 3) Although physical memory and disk sizes are actually configured in binary increments, i.e. 2**10 = 1024, they are commonly rounded off to the nearest decimal multiple of K or M bits or bytes. But this is only a ROUNDOFF issue, and generally the roundoff is in the downward direction, i.e. 10 Megs is really 1,024,000 16 K is really 16,384 etc.. 4) So where did all that disk space (810 - 770) actually go? The key phrase here was: "After formatting the drive..." Yep, that's the byte eater... the formatting process automatically reserves alot of space for administering the file system, for spare tracks, etc. typicallly 10% or more of your brand new disk! Bummer... Gen PS: I never introduced myself but I have a Thinkpad 755 something which I know very little about, which is why I don't generally contribute to these discussions... but I get alot out of them in terms of Thinkpad info, so thanks, all! ----------------------------------------------------- Genevieve Cerf, Ph.D. E.E.
