How do I eject all USB memory sticks (or flash drives) that are under a certain size?

Model: MacBook Pro
AppleScript: 2.1.1
Browser: Google Chrome 5.0.307.9
Operating System: Mac OS X (10.6)

Maybe something like this?

ejectDiskWithCapacitySmallerThen(200000) -- 200 GB


on ejectDiskWithCapacitySmallerThen(MB)
	tell application "Finder" to eject (every disk whose capacity < (MB * 1024 * 1024))
end ejectDiskWithCapacitySmallerThen

I have three permanently mounted disks (really volumes) that I can distinguish from thumb drives by size, and this dismounts the others that are smaller than a limit that excludes the permanent drives:

set tLimit to 1.0E+11
tell application "Finder"
	set V to list disks -- gives the names
	set Caps to {}
	repeat with oneDisk in V
		if (capacity of disk oneDisk < tLimit) then
			set end of Caps to {name, capacity} of disk oneDisk
		end if
	end repeat
end tell
-- then iterate through those
repeat with oneDev in Caps
	set VName to item 1 of oneDev
	set devName to do shell script "diskutil list | grep \"" & VName & "\" | awk '{print $6}'"
	do shell script "diskutil unmount /dev/" & devName
end repeat

Thanks very much for that :slight_smile:
