My 20 gig only Shows As 18.5.. What Gives?
Is this a Known Bug, or any other ideas??
Thanks

I bought a new 20gig Mac Version and have converted it to a WinPod with the 1.3 updater..I have run the Updater twice and each time I check under "Settings" on the Pod and it only reports 18.5gig free. This is of course before adding any music and I am certain it is wiped clean.
Is this a Known Bug, or any other ideas??
Thanks

That's what it's supposed to read...It's how Apple measures bytes--I think there's something about it in the faq's somewhere. So, there is nothing wrong with your ipod...dmt1 at 2007-11-15 17:05:49 >

It's not even how Apple measures it, it is how all software companies measure bytes compared to hardware companies. Check your hard drives on your computer, it will be the same. You can search about it to read more...BigIzz at 2007-11-15 17:06:50 >

I'm not too much of an expert, but I thought the missing memory was used for the operating system and stuff.TrmpledUndrfoot at 2007-11-15 17:07:48 >

Nope. It has to do entirely with the different values used by hardware and software manufactures.Plug a brand new 15 gig HD into a PC and it will come up with 13.9 GB of 13.9 GB free. My 40 GB hard drive is 37.2.
Hardware manfacturers use 1 megabyte = 1,000,000 bytes and software manuftactures use 1 megabyte = 1,048,500something bytes.
Anyway, it isn't really lost space because file size is figured out the same way hard disk space is figured out by computers so if your 40 GB hard drive were really 40 GB all your files would, by definition, be larger by the same proportion. Software could use whatever convetion they wanted, they could say 1 megabyte equalled 400 billion bytes and as long as they applied it to files and hardware the same way, you would fit the same amount of files on the disk.
(not to say the OS doesn't take up room on the iPod, but it isn't large enough to make a difference when you are talking about space in terms of tenths of gigabytes like the iPod displays.)

I tried your calculation:(20 * 1 000 * 1 000 * 1 000) / (1 024 * 1 024 * 1 024) = 18.6264515GB, so it looks like 0.1GB is missed.

Maybe but I wouldn't be suprised if it wasn't. My iPod in the about screen says I have 13.8 GB but EphPod says I have 13.90 GB.The OS is about 40 MB, so that would be .04 GB.

Thanks for the answers but I'm still a little confused. If it's supposed to read 18.5,,,does that mean I actually have 20 and it just "reads" 18.5 or am I supposed to have 18.5 and that's exactly what I have (in other words..when you buy 20 you really get 18.5) or, finally, I am hoping that you are saying I can actually put 20 gigs of files on the Pod and it will show 18.5 when it actually has 20.
I will go now and read the FAQ and perhaps answer my own question.
I was aware the all drives hold back some capacity for disk utilites etc but 1.5 gig out 20 seems like a lot.
Thanks again for the replies.

A 20 gig HDD will hold 18.5GB of data. That's just the way it is. The descriptions above are correct in that it all stems from the differences in the calculation of a megabyte. But you will only get 18.5GB's worth of mp3s on your iPod.
