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'
block.device = '/dev/sdi' (string)

info.capabilities = {'storage', 'block'} (string list)

storage.lun = 0 (0x0) (int)

storage.model = 'ST31500341AS' (string)
storage.no_partitions_hint = false (bool)
storage.originating_device = '/org/freedesktop/Hal/devices/computer' (string)
storage.partitioning_scheme = 'mbr' (string)
=> storage.removable = false (bool)
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.
