Cruzer Switch 32GB - unable to record on Bravia 32R400C

So what should I do if I need at least 30GB capacity?

Does it depend on my luck to buy better (bigger) device off the shelf?

According to this site, some models have more than 30GB free space: http://usbspeed.nirsoft.net/?o=3&g=32gb

But I wonder if that capacity is repeatable, not random…
