Comment on SMARTReporter

Q: Why are my FireWire/USB/SCSI based hard disk drives not seen/supported?
A: "Because SMARTReporter relies on the S.M.A.R.T. implementation of Mac OS X, it only supports ATA, SATA or eSATA hard disk drives, if you want S.M.A.R.T. support for your SCSI, FireWire or USB hard disk drive, send feedback to Apple."
