I partitioned my 8gb card before so I could use apsd and I don't use it anymore so I formatted my card and it still only tells me there's 6700 mb available.. I know some of the card will be taken up with software to make the card work but I didn't think it would be a gig.. did I format the card wrong?

if not the whole reason, most of the reason is that when the manufacturer makes their claim of 8GB, they are using the formula of 1000B being 1KB, 1000KB being 1MB, 1000MB being 1 GB, then when systems read the card, 1024B is 1KB, 1024KB is 1MB, 1024MB is 1GB...

so if the card is 8000000 Bytes claimed by the manuf. then 8000000/1024/1024 should be 7.6 gigs

my 8gig card shows 7.39 in my phone, so maybe the OS reserved 200MB for something?

If you partitioned your SD card for a2sd reformatting won't give you back the whole card. You need to repartition and select 0 for swap, 0 for ext and 'the rest' for FAT. That will repartition it into something your phone (and Windows/Mac/etc) can see and give you back the full available space.
