The scaleValue(longv) does not appear to handle the  1K, 1M, 1G and 1T 
correctly, shouldn't
be v >= K/M/G/T ? 1024 for 1K is OK, byte number for 1M/G/T might be too 

Seems like you are "assembling" the bits yourself, why not use our 
"powerful" (sure, a little slower:-)
j.u.Formatter, get a Formatter on top of a sb

StringBuilder sb = new StringBuilder();
Formatter fm = new Formatter(sb);

then pass the fm around and finally dump the sb.toString() to the 
out/err. This way you will
have better control of the "spacing", the \n (with "%n") and might also 
bring in some "locale"
sensitive benefits (maybe in the future).
