    Huh, I tried ext4 when I first got this thing in November. Maybe ics has given that capability, may have to try it at some point.

    On a NAS, the EXT4 is converted to the SMB (SAMBA) format by the NAS enclosure to make it readable.

    This is similar that OS X cannot write to NTFS drives without software (it can read it). But, if you share a NTFS drive on the network, OS X can write to it because it follows the SMB protocol for reading.

    Inserting an EXT4 drive directly to the tablet vs a NAS are two totally different animals.

    I use NTFS because it's a doubly-linked list file structure, and can better recover from errors. All versions of FAT are single-linked lists as far as I know--break one link in the chain, and the file cannot be recovered.

    Then there's the whole cluster size issue: any device bigger than about 2 gig, and your cluster size (smallest possible "chunk") on Fat and Fat32 is pretty large. A problem if you are storing lots of small items, such as low res pictures, text files, ebooks, small apps, and so forth. No big deal, if the smallest thing you store is the size of your average MP3, though.

    NTFS is superior in this regard too-- smaller cluster size with large devices (greater than 2gig).

    I cannot speak to the usefulness of the various Linux alternatives-- I'm told they are better than either NTFS or Fatxx. Of course, the people who tell me this are really deep into the Linux culture, so.... <evil grin> but they are probably at least mostly right. Linux, being a crowd-sourced culture, tends to eliminate things that are really wonky pretty quickly.

    I do wish the Android OS understood other formats, though.... both Fatxx and NTFS are children of Micro$oft, with all that that implies.

    But more than that? I wish Google had not removed the FORMAT command from Android HC/ICS .... it would make things ever so much more simple, if you could format these on your tablet ....

    Yes that is what the 64 stands for. 64 Kb That is Sixty Four Kilobytes. Not MB and not Gb. And we used to program some great games, music and lots of other stuff on that, one line at a time :-) #backintheday

    My first "computer" was a Coleco Vision machine. Yeah, I liked to gamble in those days. I was fond of hacking my own controllers too-- I built several variations to the originals the console came with-- modified those too, to have a standard Atari-type jack in the back, so I could use modified Atari-type controllers. I even had the Coleco trackball-- that ball was huge-- the size of a large CUE ball from pool it was. Lots of mass, meant you couldn't change direction very quickly. But it'd spin for minutes, if you flicked it the right way... heh.

    My first real computer was an IBM PC. Yes the original beige box made by IBM, weighing about 50 pounds (most of which was the heavy-gauge steel case-- you could literally stand on those suckers, and not bend them). It had a whopping 8k RAM, which I quickly expanded by plugging in 16-pin RAM modules, to the maximum 16k (that's kilobytes--- the total memory model in these 8/16 bit hybrids was only 1meg, 360 of which was reserved and unavailable for general computing).

    "640K ought to be enough for anybody." - Bill Gates, circa 1981

    But us wily programmers learned to utilize some of that 360k "reserved" space with clever Assembly Language programs-- I know I did exactly that, back in 1986 or so. I needed some fast buffers for sorting purposes, and pushing it out to the then slow 8bit bus hard disks was simply not feasible. So I wrote an assembly language program that utilized the video buffer as temporary storage for sorting those (then) massive structures. It worked. My first go-round did use the hard disk, and typically took about an hour to sort the pieces of the map (it was a mapping program). By buffering it in the unused color video RAM (we required color video for our program, but this program was only using a text-based screen at the time, so the color buffers were free to use) I cut it to less than 5 minutes.

    Oh, the memories of limited systems running DOS 2.21... networking? Ha! A pipe dream, at best... unless you worked for DARPA, of course...
