we have the same drives as you have, those so called '144 GB' ones :-) When performing a sysconfig -r the filer showed me those 137 GB and i, young as i am, thought that the filer already made the conversion to binary for me. By rule of thumb this number seemed to be correct to me.
Well with a drive capacity of 134 i really get close to what i am locking for!
Yep. Looks like 137 is not a pure "binary Gigabyte" unit for them, but a hybrid of binary/decimal.
Reported size 144GB => 1.44 * 10^11 bytes
In units of 10 ^ 9 ( 1 billion ) => 144 10^6 * 2^10 (1 million KiB) => 140.6 10^3 * 2^20 (1000 MiB) => 137.3 2^30 (1 GiB) => 134.1
