Hi,

As I have seen some broken USB-Harddisks now, I would like to submit a WISH:

smartd, when started with options for devicescan and being told, they could be removable, and seeing that smart-notifier connects to smartd via dbus: couldn't smartd check usb-disks when they're connected after starting smartd? (using udisks dbus interface or somesuch) And if it does so already, please document it (then I woulnd't have asked).

Thank you VERY much for great work, which repeatedly saved me from data-loss.

Support for external USB or FW drives is currently lacking on Mac OS X because that OS does not provide SCSI passthrough natively. There is however a kernel extension that promises to add exactly this: ​https://github.com/kasbert/OS-X-SAT-SMART-Driver . It would be great if the appropriate code could be added to os_darwin.* to support external drives under OS X also. I've taken a quick look at the code, but it doesn't look to be an easy fix without a serious bit of introduction...

Current smartd reports send by mail only list device name (e.g. /dev/sdc) which is not enough to easily identify the problematic disk.

It will be better to add some more info to the report, e.g. something like:

The following warning/error was logged by the smartd daemon:

Device: /dev/sdc [SAT], 4 Offline uncorrectable sectors

Device Model: WDC WD20EARS-00MVWB0 Serial Number: WD-WMAZ2026xxxxx User Capacity: 2,000,398,934,016 bytes [2.00 TB]

(above is easily obtained by smartctl -i /dev/sdc |egrep "Device Model|Serial Number|User Capacity")
