followup:

The thinkwiki ultrabay script references scsi devices. The swap is 
between a dvd and a ata disk. Neither are scsi. How should the script:

|# echo 0 0 0 >  /sys/class/scsi_host/host1/scan

and 
|

|# echo 1 > /sys/class/scsi_device/1\:0\:0\:0/device/delete|
|# echo eject >  /proc/acpi/ibm/bay|

be changed to work with /dev/hdc?

The thinkwiki ultrabay script references scsi devices. The swap is
between a dvd and a ata disk. Neither are scsi. How should the script: <br>
<pre><code

and

<code
 style="white-space: nowrap; color: rgb(73, 89, 136); background-color: white;"># echo eject &gt;  /proc/acpi/ibm/bay</code>
</pre>

be changed to work with /dev/hdc?<br>

The system is FC6 with a 2.6.21.1 kernel
  <br>
  <br>
Kernel config checked and ata_piix module loaded.
  <br>
Scripts in thinkpad wiki installed.
  <br>
  <br>
acpi appears to be working
  <br>
the system beeps whenever the bay eject lever is released or closed.
  <br>
  <br>
/proc/partition does not change
  <br>
  <br>
The bay works successfully on boot.
  <br>
  <br>
dmesg shows command errors attempting to read device

The system is a T41 running 2.6.21.1 kernel. The system does not unload
devices from the ultra bay. I booted with a hard disk carrier in the
bay. That worked as it should have.
    <br>
    <br>
Then I performed an eject command and removed the drive. I then
inserted a DVD drive. It was not recognized.
    <br>
    <br>
How can this be done? What are the config parameters? What am I
missing?
