Added sdparm
Thanks for adding it, but unfortunately, the version you've included doesn't actually work because it's the dynamically-linked version that depends on libsgutils2.
When you run it, it says "sdparm: error while loading shared libraries: libsgutils2.so.2: cannot open shared object file: No such file or directory"
I will admit I have very little knowledge of linux packaging, but I've tested the versions from this page: http://sg.danny.cz/sg/sdparm.html#mozTocId166213 and can confirm the executables in the .debs marked with [built without sgutils lib dependency] do work on the current unraid with no additional dependencies. (I just have to re-add it everytime I reboot.)
