Description of problem:
During the final step of the installation using anaconda, the following error 
is displayed after the package selection when you hit "next" to begin 
formatting the drives: "Error informing the kernel about modifications to 
partition /dev/hdc1 - device or resource busy. This means Linux won't know 
about any changes you made to /dev/hdc1 util reboot - so you shouldn't mount 
it or use it in any way before booting." The /dev/hdc is a removable 240gb IDE 
drive that is formatted ext3 into two 120gb partitions /dev/hdc1 
and /dev/hdc2. The only solution so far has been to reinstall everything but 
do not format the removeable drive. The primary drive /dev/hda is a 40gb IDE 
drive.

Version-Release number of selected component (if applicable):
kernel-2.6.11-1.1369, rpm-4.4.1-21, anaconda-10.2.1.5-2

How reproducible:
everytime

Steps to Reproduce:
1. Begin the installation of Fedora Core using anaconda
2. Format dirves manually using disk druid. The first drive /dev/hda is a 40gb 
IDE drive that is formatted as follows: /dev/ha1 = /boot =102mb, dev/hda2 
= /usr = 10236mb, /dev/hda3 = /var = 5122mb, /dev/hda4 = extended 
partition, /dev/hda5 = / = 5122mb, /dev/hda6 = /home = 5122mb, /dev/hda7 
= /tmp = 1024mb, dev/hda8 = swap = 777mb, /dev/hda9 = /opt = 10652mb
3. Formatted manually the second rive a remoavble 240gb IDE as 
follows: /dev/hdc1 = /bkup/mis = 115091mb, /dev/hdc2 = bkup/001 = 123382mb
4. Custom installed network setting, firewall (allowed ssh), LinuxSE, time 
zone and various packages the hit "next" to the screen before the step of the 
installation.
5. hit "next" to begin the final installation and the system hangs for a few 
minutes then displays the error mention in the description.   
  
Actual results:
Received the error message mentioned in the "Description" andI saved the dump 
to a floppy disk and rebooted and ran the install again with the same error 
even when I tried to create one partition on the second drive. Finally had to 
run through the setup again but the last time I did not format or partition 
the second hard drive.

Expected results:
Fedora Core 4 should have formatted the second removable drive into two 
partions as it had when it was formatted with Fedora Core 3 and finished with 
the installation and rebooted.

Additional info:
I will submit the crash report once the bugreport has been filed. Also the 
machine is a Dell optiplex 260 Pentium 4 2,80ghz 521 memory. The hard drives 
are both Western Digital. The Removable case is a Store Caes Technology.
