Hi Pandu, ext3/4 is what is recommended by www.beagleboard.org/Robert Nelson/Angstrom Linux...but I have to confess that took this as simply "given". The other thing is: With sdcards one have to keep an eye on what part of the sdcard is written how often repeatedly, since sdcards tends to wear out. I read somewhere on the internet (dont remember where...sorry) that Samsung has offered code to the Linux kernel, which implements a special FS especially suitable and made for sdcards. But I dont know its name and whether it is already available in the kernel sources... Best regards, mcc
