vfat has a size limitation of 2GB. you need to format it in fat32 or ext2/ext3 to get a single partition over 2GB.
alternatively, you can create multiple 2GB vfat partitions to use all the space on the card

I think that FAT has a 2GB limit and VFAT under linux includes support for FAT32 and up to 8TB.

anyone tried new kernel from http://intr.overt.org/blog/ ?
I wonder if 4GB transcend 150x is faster with this kernel. It includes high speed (50Mhz bus speed) SD mode needed to fully use 150x mode of this card. could anyone with this card post output of
?
Thanks.

the test reads 160MB so with 128MB card it ends earlier. But both speeds are around 7.5-8MB/s.
I wonder if Transcend 150x 4GB SD or Kingston 2GB mmcmobile is faster. Kernel contains also high speed and wider bus feature for mmcmobile cards so Kingston one should be definitely faster than before and similar in speed with 150x SD cards.

I flashed the new kernel but things are not much better for me. I've got 4.8GB on my 8GB card by scp'ing video files over. But whenever I try to turn swap on to that card, I get errors
[31025.502105] FAT: Filesystem panic (dev mmcblk0p1)
[31025.502136] fat_bmap_cluster: request beyond EOF (i_pos 117353478)
and the filesystem is put into readonly mode. I have to reboot to get it back.
It's like the swap applet doesn't understand partitions >2GB but when I use scp to copy a file over, it works file. Like part of the OS is >2GB aware but not all.
Is all this stuff working for others? Maybe my card is corrupt or something but there doesn't seem to be anyway to fsck it. I can't find fsck.vfat.

OK, so I removed the video files and got the filesystem under 2GB of data. I then could add a swap file. Strange which apps can write over the 2GB filesystem boundary and which can't. I know scp has no problems.

ok, again, i am a total newbie and would apprciate some step by step help please? i have absolutely no experience in linux, none, nothing. i know there are alot of peopl out there who are in the same boat as me so maybe a step by step instruction guide could be produced then posted on here as seperate thread?
i have bought the N800 and also have a transcend 4Gb highspeed 150X SD card from mobymemory.
i know i need to flash the kernel, whatever that is, to enable me to use the full amount of the card. I want to use the 4GB card in the internal slot for Music, pics etc but want to use another 4Gb, or 8GB card for hotswapping videos whilst away.
I need to know how to flash the kernel to make this work. Please do not refer me to post 73 as this means nothing to me and is just a window full of symbols.
Thankyou very very much for your patience, i know its frustrating for you all to deal with linux virgins like us! ...thanks.

I also broke one by trying to reformat it to use smaller sectors using mkfs.vfat and now I can't seem to make a vfat filesystem that is both 8GB and recognized by the N800. Best I can do is 2GB. Any ideas appreciated.
