Hello,
(originally posted at carbon-dev)
I'd like to retrieve the system volume's hard disk serial number.
For drives which indeed support such a serial number it can be read
using the ioreg tool.
Although I'd prefer to read the hard disk serial number using an
API (e.g. IOKit) instead of using a dedicated tool, I'm more
concerned about the different paths I seem to have to go through
the dictionaries to get different drives' serial numbers when the
drives are attached by different busses (see ioreg output below).
Also, the *keys* used to query the dictionary for the S/N differ,
e.g. "device serial" vs. "Serial Number".
Apple's System Profiler gets them all, but maybe it also uses
different code to read the S/N from different devices?
Is there a recommended / unified way to retrieve a hard drive's
serial number?
At least, are there known pitfalls?
Thanks for pointers, links, sample code snippets, comments, or
whatever you might consider useful!
Try looking at smartmontools for some examples on how to query
different drives.
