Hi, I bought my second WD Elements 1.5 TB External HD last night and I cleaned out my old 250 GB LaCie External HD today. I know the 1.5 TB should read at about 1.4 TB and the 250 GB has always read at about 232 GB. Suddenly I have them at 1.5 TB and 249.4 GB respectively. Sounds like things the way they should be, I know, but anyone who's been paying attention knows something's just not right there. Anyone know what happened? And if it's not a glitch tell me how to reproduce the result on my other HDs. Thanks in advance.
