'2) Change the function to a sub, remove
' the last line of code (SwapBytes = b()),
' and take advantage of the fact the
' original byte array is being passed
' to the function ByRef, therefore any
' changes made to the passed data are
' actually being made to the original data.
' With this workaround the calling code
' also requires modification:
'
' di.Model = StrConv(SwapBytes(IDSEC.sModelNumber), vbUnicode)

' ... to ...

IDE drives support the SMART IDE specification. The code on this page
shows how to test for a SMART IDE drive and if present, return the
drive's model and serial number. As coded the routine loops through the
first four possible drives; this could be extended if required.
