I can not quite follow what you are doing, but first and foremost I asked you to post computer output between CODE tags. This I get a headache from.
I can follow more or less what you did with *fdisk. *You created an empty partition table with the o command (but fdisk allready told you it did the same just before you repeated this), then used the p command to check this and it did:
Command (m for help): p
Disk /dev/sde: 4041 MB, 4041211904 bytes
125 heads, 62 sectors/track, 1018 cylinders
Units = cylinders of 7750 * 512 = 3968000 bytes
Disk identifier: 0x0f7a8580
Device Boot Start End Blocks Id System
Then you used the write command to wrtite it to disk, which it did (I presume, why not).
Now what follows I can not understand. I do not know what partprobe does, but next you are going to
mount -t ext3 /dev/sde /tmp/mmc
But you have no file system on /dev/sde, you just have an empty partition table!
I guess you lack some knowledge about what you try to do (forgive me if I am wrong). I advise you to read and understand SDB:Basics of partitions, filesystems, mount points - openSUSE
Also when you want to use the whole of */dev/sde *for a file system, why partition it? Partitioning is only needed when you want to split up (partition) your disk in several parts. You can still split it into one part (which wiill then be known as /dev/sde1), but that is not needed.
Having the whole disk, or a partition, then most of the time (but not allways) one wants to use this as a file system. Then that file system must be created using a form of mkfs.
When you have a file system, then and only then, you can mount this on a directory (that must exist) of your choice and that directory is called a mount point.
Why, if you lack the knowledge of doing this in the CLI, don’t you use YaST as I suggested earlier. It is there to take care of people for which doing this is not a routine task.
Maybe you should forget a bit about all the information you found in all sorts of places on the internet. You asked here and we are trying to help you. But when you intermingle executing our advice with all sorts of other things you don’t realy understand in the middle of our help sequence, we can not guarantee that we understand what you are doing.
