[smartmontools-support] smartctl hangs using SeriTek/1SM2, ST9500420AS, OWC Mercury Elite-AL Pro mini

[<tri...@my...>]

When using "smartctl 5.39.1" on a 17" G4 PowerBook running Mac OS X 10.4.11, various smartctl commands will hang when applying them to an eSATA drive enclosure (OWC Mercury Elite-AL Pro mini) with a 500GB Hitachi Travelstar 7K500 (ST9500420AS) disk through a SeriTek/1SM2 cardbus card. using smartctl on other disks (one in the data base & one not) on the same PowerBook work properly. 

Various Mac OS X applications & commands yield these results:

Name              Result
====              ======
Disk Utility      S.M.A.R.T. Status: Not Supported
diskutil          SMART Status: Verified (output appended to end of this message)
TechTool Pro 5    SMART Results Passed

I've appended some of the commands & their outputs to this message. Is there other informtiton I can supply?
