This is a bit old.  Here's the start of thread in the archives: 
 <http://lists.fedoraproject.org/pipermail/users/2010-April/370236.html>

| I have an eSATA external hard drive case.  I want to hotplug / unplug it.
| 
| My system is Fedora 11.

I've since upgraded for Fedora 13.  I still have this problem.

| I added an external eSATA port on my desktop computer by adding a bracket 
| (with an internal cable connected to one of the ordinary SATA sockets on 
| the motherboard.)
| 
| The SATA controller is an intel ICH9R.  To make hotplug work, I needed
| to go the computer's BIOS and change the SATA mode to AHCI (it was
| IDE).
| 
| I can now hotplug the drive.
| 
| I cannot unplug the drive.  If I tell the system to eject the drive,
| it complains:
| 
|     # eject /dev/sdi
|     eject: device "/dev/sdi" doesn't have a removable or hotpluggable flag
|     # cat /sys/block/sdi/removable 
|     0
| (I don't know where or what a hotpluggable flag is.)

| My guess is some kind of HAL rule but I'm not an initiate.  Maybe
| something in here would work:

I still don't know, but lshal(1) tells me a bit:

	udi = '/org/freedesktop/Hal/devices/storage_serial_ST31500341AS_9VS0N5K1'

	  storage.no_partitions_hint = false  (bool)
	  storage.originating_device = '/org/freedesktop/Hal/devices/computer'  (string)
	  storage.partitioning_scheme = 'mbr'  (string)

	  storage.removable.media_available = true  (bool)
	  storage.removable.media_size = 1500301910016  (0x15d50f66000)  (uint64)
=>	  storage.requires_eject = false  (bool)
	  storage.serial = 'ST31500341AS_9VS0N5K1'  (string)
	  storage.size = 1500301910016  (0x15d50f66000)  (uint64)
	  storage.vendor = 'ATA'  (string)

All those marked settings look wrong to me.  I guess HAL rules could
fix this.  Surely I'm not the first to hit this problem.
