Crasy "fdisk -l" output


In Kubuntu, after mounting a 8GB vfat USB stick, and doing "fdisk -l" I get:
Code:
delbert@delbert:~$ sudo fdisk -l

This doesn't look like a partition table
Probably you selected the wrong device.

Partition table entries are not in disk order
Anybody with any idea what went wrong here? Should I format the USB stick in linux?

looks good to me sdc is an incrypted windows partion. If it isn't then it needs to be
dosfsck -f -r /dev/sdc but this looks like a fresh install and the program wrote the fstab as it was seen. if dosfsck -f -r /dev/sdc does not repair then it is encrypted.
my choice would to wipe out all the non linux partions and use all linux.
if you cfdisk /dev/sdc it will return bad block or bad stuff. and if you try to fdisk /dev/sdc and it does not work it is encrypted. you will need to use the program that encrypted it to fix or repair or format. good luck.

Thanks I did the filesystem checks --- note that today the system read the USB stick as sdb and not as sdc:
Code:
delbert@delbert:~/Documents$ sudo dosfsck -f -r /dev/sdb
dosfsck 2.11, 12 Mar 2005, FAT32, LFN
/dev/sdb: 3 files, 245785/493326 clusters
As you said for:

Code:
sudo cfdisk /dev/sdc
I get a black screen with:
"FATAL ERROR: Bad primary partition 0: Partition begins after end-of-disk: Press any key to exit cfdisk"

So this means that the USB is a FAT32. Should I re-format it as FAT32 with Kubuntu's partition editor, because I have no idea what programme formatted it initially --- just bought it now. I would like the stick to be read by a Winblows machine as well, hence the vfat-like type I want.

it nead's to stay FAT32 if it's gowing to be seen by windows.

why do yo want to format it?

I have a 2 Gig and have formated it partitioned it and used it to death and it still works fine.

rite now it reads as

Model: Tribeca (scsi)
Disk /dev/sda: 2097MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number Start End Size Type File system Flags
1 32.3kB 1629MB 1629MB primary fat32 boot
3 1629MB 1678MB 49.4MB primary fat16
2 1678MB 2089MB 411MB extended
5 1678MB 2089MB 411MB logical linux-swap


(parted)

and runs a live distro ;-)

ok here is the problem the only time I have ever seen an out put on a drive like that was a usb flash pen. and I had to /fdisk/ /dev/sdc/
and delete all the partitions then create a new one then format it as 0b
b win 95 32 then your done now windows can use it and linux can use it.
if it does not take then you have to reformat it with windows and the company's software.

I think fdisk has issues with larg partitions use parted if you have it.

ya why not?---- repartition and format as 1 big FAT32
