Default Resizing vfat partition with fdisk ??

Hi there,

I have some troubles while resizing my vfat partition with fdisk. First it was strange because in fdisk the partitions were fine as following:

-----------------
debian-lap:~# fdisk -l /dev/sdb



Disk /dev/sdb: 4022 MB, 4022337536 bytes


29 heads, 28 sectors/track, 9675 cylinders


Units = cylinders of 812 * 512 = 415744 bytes


Disk identifier: 0x04030201



* *Device Boot* * * Start*
* * * *End* * *
Blocks* *Id* System


/dev/sdb1* * * * * * *
*1* * * * 1928* * *
782754* * b* W95 FAT32


/dev/sdb2* * * * * *
1929* * * * 9675* *
*3145282* * b* W95 FAT32


debian-lap:~#

debian-lap:~# fdisk -l /dev/sdb1



Disk /dev/sdb1: 801 MB, 801540096 bytes


29 heads, 28 sectors/track, 1927 cylinders


Units = cylinders of 812 * 512 = 415744 bytes


Disk identifier: 0x00000000



* * *Device Boot* * *
Start* * * * *End* *
* Blocks* *Id* System


debian-lap:~#

debian-lap:~# fdisk -l /dev/sdb2



Disk /dev/sdb2: 3220 MB, 3220768768 bytes


29 heads, 28 sectors/track, 7747 cylinders


Units = cylinders of 812 * 512 = 415744 bytes


Disk identifier: 0x00000000



* * *Device Boot* * *
Start* * * * *End* *
* Blocks* *Id* System


debian-lap:~#












-----------------

But the system was recognizing a different size like:

-----------------
debian-lap:~# df -h /dev/sdb1 /dev/sdb2


Filesystem* * * * * *
Size* Used Avail Use% Mounted on


/dev/sdb1* * * * * *
*3.8G* 395M* 3.4G* 11% /media/disk


/dev/sdb2* * * * * *
*3.0G* 4.0K* 3.0G* *1% /mnt/flash


debian-lap:~#

-----------------

After I tried to fix it using the gparted (but my goal is to do that using fdisk tool) and now the number of cylinders seems decreased from 9675 to 489, look:


-----------------
debian-lap:~# fdisk -l /dev/sdb



Disk /dev/sdb: 4022 MB, 4022337536 bytes


255 heads, 63 sectors/track, 489 cylinders


Units = cylinders of 16065 * 512 = 8225280 bytes


Disk identifier: 0x04030201



* *Device Boot* * * Start*
* * * *End* * *
Blocks* *Id* System


/dev/sdb1* *** * * * *
*1* * * * *489* *
*3927861* * b* W95 FAT32


debian-lap:~#





-----------------

Any idea ?

Thanks.

After you finished fdisk, did fdisk tell you that it was using the new
or old partition table and to reboot?
If this is a USB disc then instead of rebooting you can unplug and replug.

<erno> hm. I've lost a machine.. literally _lost_. it responds to
ping, it works completely, I just can't figure out where in my
apartment it is.

gparted is the correct tool for resizing partitions.

Yes, there's data but if I loose it no problem, I'm using my usb flash drive to test this partition resize.

Like Ron said, gparted is the correct tool to use if there is dada you
want to keep.
I'd suggest that at least some of your data is toast from playing with fdisk.
If you want to delete and recreate the partitions (then filesystems
later) using fdisk it will work.

I think what you are doing isn't working because possibly some inodes
exist beyond the new partition boundary and thengs are getting
confused.
