Here is an simplified 'system_profiler' output approach. It returns one
tab-delimited line of info per detachable USB storage device, with all
the data items known to system_profiler for each device. NOTE: It
expects system_profiler output to be in English.
function macUsbDrives
-- get USB device info from system profiler
put shell("system_profiler -detailLevel full SPUSBDataType") into tData
-- convert data to one line per USB device
replace (colon & cr & cr) with numToChar(245) in tData -- device name
replace (cr & cr) with numtoChar(250) in tData
replace cr with tab in tData
replace numtoChar(245) with (colon & tab) in tData
replace numtoChar(250) with cr in tData
-- remove records for all but USB drives (English data only)
filter tData with "*Detachable Drive: Yes*"
-- remove space-padding from items in each line
set the itemDel to tab
repeat for each line tLine in tData
repeat for each item tItem in tLine
put word 1 to -1 of tItem & tab after tNewData
end repeat
put cr into last char of tNewData
end repeat
delete last char of tNewData
-- return the data
return tNewData
end macUsbDrives
Very helpful Phil, and I appreciate your posting it, but unfortunately
the issue I found with using system_profiler is that it doesn't report
the volume name as it appears to the user on the desktop.
I had hoped there would be some reasonably simple way to get a list of
mounted volumes that looks something like this:
<driveName> <mountPoint> <type>
...where <driveName> is the name as it appears in the Finder,
<mountPoint> is either "/" or "Volumes/<drivename>", and <type> is
either ATA, SCSI, CD/DVD, USB, etc.
With what I've learned in this thread it seems I may be able to use
output from system_profiler checked against output from AppleScript
calls to obtain such a list.
For the future, I see that Jeanne DeVoto had submitted an RQCC request
for "the detailed volumes" which could do what I need if implemented as
described there:

In the meantime, it looks like I have some parsing to do and some
homework to figure out the details of getting this info for Win Vista,
Win 7, and Linux. I'll post the result here once I get it working.
