Hi,

I bought a 770 last week with an additional 1GB memery card from Extrememory.

With the original 64MB card I have no problems. I see the content in the file-manager and when I plug in the usb-cable on the pc.

With the 1GB card it's different. When I format it in the 770, I can work in the 770, but the card doesn't show up in the pc.
When I format it on the pc with FAT16 either with win xp or linux, I see the content from the pc when I connect usb, but nothing is visible in the 770.

Has anyone seen similar behaviour? What am I doing wrong?

I've partitioned mine as
128 MB FAT32
850 MB ext2
24 MB linux swap

I created the partitions and formatted them with gparted in Fedora Core 5 while the card was in the 770 connected to the PC with the USB cable.
I've had no issues. But then again, I don't use the USB cable to transfer files. I always use scp (part of Open SSH). I also use mmc-unionfs which mounts my home and install directories on the mmc card.

Is the PC running Windows? Windows has no support for Linux filesystems like ext2/ext3, so wouldn't be able to read the partitions on your card that use these filesystems.

A quick Google search for "ext2 on Windows" returned this as the top result:

And it's free.

Hi,

I tried all different sort of partitioning with win and linux with FAT16 with no success.

The latest is, that I formatted the card with the 770. Then when I connect a pc with koppix the card will be mounted with /dev/sda (not sda1). If I start fdisk, there are no partition informations, but I can see in konquerer the created files. I also can add files, which I can see on the 770.
When I connect the cable on a windows pc, it is not even recognized and mounted with a letter.

When I take the card out of the 770 and insert it in a card reader on the windoes pc, I have full access to the files and can also add files which could be read from the 770 when I reinsert the card.

So, where is the problem and the difference in having the card in a reader or in the 770?

PS: The original card, which works perfect, shows in fdisk as partitioned as FAT16.

Thanks guys with the ext2 hints.

As far as I see it, there is no ext2-problem, because the 770 does not format the mmc-card in ext2. The original card at least shows up as FAT16.
