Two identical 16GB iPod nano 6Gs -- iTunes reports different total capacities!

[kfscoll]

I have two identical iPod nano 6Gs -- same color, both 16GB, both formatted for Mac, everything -- yet iTunes reports the capacity of one at 14.98GB and the other at 14.89GB! What's the explanation for this? Why am I being cheated out of .09GB (~90MB -- not insignificant storage space) on one of 'em?

Either way, that's a good amount of storage to get out of what they call 16GB of flash memory. My touch barely holds 7GB out of its 8. The 90MB difference isn't really as significant as it looks, as iPods never completely fill themselves for some annoying reason, so it's likely that the total difference in capacity will be 5-10 songs

Restore it.
I tried, didn't make a difference. Oh well.
