hi,
just wanted to tell you that I successfully changed the internal card of my glow hd to a 32 GB all partitions ext3 formated sd card following frostschutz' tutorial. did it on my mac - had to take out the sd card for formating. I used ExtFs for Mac by Paragon for formating and accessing the card - paragon is slow as hell but does the job.
the reader runs perfectly smooth afterwards. like it!

thx frostschutz!
btw: has anybody tried a 200GB MicroSD Card yet?
