Fedora Users — Re: Issues trying to partition a USB drive

Hi List;

I have a 320G SATA drive that used to have Fedora 8 on it, I no longerneed it as a main Linux drive so I want to use is as USB storage.

However I'm having issues trying to fdisk the drive into a singlepartition.

Here's what I did :
1) put the drive in a USB 2.0 enclosure
2) plugged the USB into my Fedora box
3) as root ran 'fdisk /dev/sdb'
4) removed all partitions on the drive and wrote the changes

5) rebooted my Fedora box
6) ran 'fdisk /dev/sdb' again

at this point I get this if I print the partition table:

/Command (m for help): p

Disk /dev/sdb: 320.0 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x0000733a/

7) added a single partition:- choose 'p' for primary partition- choose '1' for partition number

  - choose '1' for the first cyllinder
  - choose '38913' for the last cyllinder

Like this:

/Command (m for help): n
Command action
  e   extended
  p   primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-38913, default 1): 1
Last cylinder or +size or +sizeM or +sizeK (1-38913, default 38913): 38913/

8) wrote the changes (w)9) I went back into fdisk and printed the partition table:


/Command (m for help): p

Disk /dev/sdb: 320.0 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x0000733a

  Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       38913   312568641   83  Linux/


10) rebooted the Fedora box again

11) plugged in the USB drive

KDE asks what to do - I say open in a new window.
What I see is the data from my old /boot file system

Also now if I do a 'df -h' I see the second (USB) drive as only the sizeof the old /boot file system (1.9G) not the 320G I expect to see:


/$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                             48G   35G   11G  77% /
/dev/sda1             190M   19M  162M  11% /boot
tmpfs                    506M  364K  505M   1% /dev/shm
/dev/sdb1             1.9G   52M  1.8G   3% /media/-boot1/


What am I doing wrong ?

Thanks in advance...

Because you did not format the new partition, it is getting filesystem size and usage from the old file system. In fact, at thispoint, you could probably recover the old partition table and filesystems. If you unmount /dev/sdb1, and run "mke2fs /dev/sdb1" youwill end up with an empty file system using the full partition.


Make sure you use the correct device...
