Memory Card's partition table.
 
Hello everyone =)

I'll try to explain this as good as I can.
So:
Im doing a partition on a MMC Memory card.
Quote:
Command (m for help): p

Disk /dev/sdd1: 510 MB, 510798336 bytes
16 heads, 61 sectors/track, 1022 cylinders
Units = cylinders of 976 * 512 = 499712 bytes

Device Boot Start End Blocks Id System
/dev/sdd1p1 1 1022 498705+ 83 Linux

Command (m for help):
However, when I make a filesystem to the partition, the partition table resets!

After doing the filesystem, when I look to fdisk, it says:
Quote:
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
And the partition table is empty.
What's the correct way of doing the partitions and filesystems? Or is it even possible?

PS. If I try mke2fs /dev/sdd1p1 it says:
Quote:
mke2fs 1.38 (30-Jun-2005)
Could not stat /dev/sdd1p1 --- No such file or directory

The device apparently does not exist; did you specify it correctly?
I am bit confused :confused:

EDIT: after doing the filesystem, the card works fine. But I cant install GRUB to it :/

What do you mean "the card work fine"? What's the output of dmesg and df?

I mean I can put files to it. But theres "no" partition table.

I solved this. Stupid me!

I noticed today that I had been accidentally using fdisk /dev/sdd1 when I should be using fdisk /dev/sdd
