Not to be confused with:
kibibyte (KiB)    2^10      1024
mebibyte (MiB)    2^20      1048576
gibibyte (GiB)    2^30      1073741824
tebibyte (TiB)    2^40      
pebibyte (PiB)    2^50      
exbibyte (EiB)    2^60
zebibyte (ZiB)    2^70
yobibyte (YiB)    2^80

Is that for real?

No joke.  Years ago there was some uproar because hard drive manufacturers measured capacity in kilobytes and megabytes but certain OS components measured in kibibytes and mebibytes but reported it as KiB and MiB which people confused as kilobytes and megabytes.  So a 20 gigabyte hard drive only has a 19,073 mebibyte unformatted capacity.  People thought they weren't getting the capacity as advertised! Where's the missing gigabyte!?

  Yeah, banks are famous for that dirty trick, too. APR and APY are different animals. APY is what you get on the year for the money you have deposited. APR is mathematical horseshit based on interest compounded on the month*12; which results in a
lower 'advertised' annual percentage rate than you are actually paying...

Kinda' weird....

I'm trying to recover data from a damaged laptop SATA drive using Linux ddrescue and gpart. I just noticed that the disk sizes are given in MB and then (Mib in parenthesis).
