ok guys... I've figured it out... googled everything I saw but not the line "emhttpd: device /dev/sdb has size zero"
Solution was also within unraid forums so I'm just dumb enough to not search thoroughly enough
 
about halfway down this thread i found the solution
SAS Drive 520 sector size - General Support - Unraid
 
Reformat a SAS HDD to different block sizes mainly 512 to use in UNRAID This took me a few hours to find and work out but was so much needed OK so I have just now done this for myself by installing sg3_utils onto my UNRAID OS using installpkg all using terminal 1. download the package into a tmp dir # wget http://slackware.cs.utah.edu/pub/slackware/slackware64-14.1/slackware64/l/sg3_utils-1.36-x86_64-1.txz 2. run this from that tmp dir after the download to install sg3_utils # upgradepkg --install-new sg3_utils-1.36-x86_64-1.txz 3. use this command to show SAS HDD's # sg_scan -i 4. this command to format 'obviously /dev/XXX should be the HDD u wish to format MAKE SURE ITS THE RIGHT ONE! # sg_format --format --size=512 -v /dev/XXX this has been allowing me to reformat the block size and use previously non usable drives saving buttonnes of money WARNING this format will destroy a HDD if interrupted during this process if you can a UPS is recommended have a great day I love UNRAID! only needed 3 and 4 ... after some time and rebooting the first disk is showing up SundarNET is the MVP here
