formatting USB thumbdrive under linux - Error re-reading the partition table failed with error 22:

Linux - Redhat Fedora
Thumb Drive - Sandisk 4GB micro
Error: Warning: re-reading the partition table failed with error 22: Invalid argument. The kernel still uses
the old table. The new table will be used at the next reboot.

Steps:
fdisk -l  (shows thumbdrive as /dev/sdb1)
Created 3 partitions - Part 1 = 50M, Part 2 = 512MB, Part 3 = 3.456GB
fdisk /dev/sdb1  (/dev/sdb1 boot=*, start=1, end = 7965, blocks=4013865, ID=6, system=W95 fat32)
n [enter], P [enter], 1 [enter], [enter], +50M [enter], n [enter], p [enter], 2 [enter], [enter] (default =14), +512M [enter], n [enter], p [enter],  3 [enter] (default 42),  [enter] (last cyl - 1019), A, 1, t, 2 , 82, p, w
After I press p - it prints the following configuration:
/dev/sdb1p1 boot *, start = 1, end = 13, blocks = 51150, ID = 83, Linux
 /dev/sdb1p2 boot , start = 14, end = 141, blocks = 503936, ID = 82, Linux  swap / solaris
/dev/sdb1p3 boot , start = 142, end = 1019, blocks = 3456686, ID = 83, Linux

After I press w - to write to the partitioh it gives me the error:
Error: Warning: re-reading the partition table failed with error 22: Invalid argument. The kernel still uses
the old table. The new table will be used at the next reboot.

When I reboot and try to format I get the following error: The device apparently does not exist ...
mkfs.ext3 /dev/sda1p1 (gives the above error)
mkfs.ext3 /dev/sda1 - seems to work, but I can't access the individual partitions.
also, if I do an fdisk -l it still shows the drive as w95 fat 32. What am I doing wrong.

Is a GUI setup on that PC? If yes, have you tried using GParted or QtParted to delete the partitions?

Try fdisk again to delete the partitions then reboot.

Thanks for the quick response rindi. I tried deleting the partition twice and rebooting.
I can't seem to format the following partitions, and everytime I try to repartition the usb thumb drive, I get the error 22. I reboot after the error since I want the tables to be updated.

Error 22 is EINVAL (Invalid argument). What do you see if you try "fdisk /dev/sdb"?

I humbly thank you guys for all of your help. I don't know much about linux.
One other question. If I boot from a linux livecd, what is the CD designation. Is it /boot ?

rindiCommented:
No. It'll look just as if you have booted from HD. /boot is just the folder where the kernel and boot loader normally is. The CD is often mounted on /cdrom.

Thank you all for your help. Rindi, I was able to download a livecd with Gparted, deleted the partitions and recreated them via gparted. My partitions finally took. It took me 2 days to fix, but it would have taken me a lot longer without your help.

Have a great day!

You can also use the text based parted since it's already available out of the box.
