Re: [PLUG] Copying files to multiple volumes

[Walt Mankowski via plug <plug@lists.phillylinux.org>]

Interesting! Of course this is all moot now since they won't come
close to fitting on 2 drives.

Speaking of which, can we as an industry decide whether K,M,G,
etc. refer to powers of 1000 or 1024? The reason I thought it might
fit was because the "4 TB" drive had 4 trillion bytes, whereas all the
other TBs were using 1024^4.

Sigh.
