In any case doesn't that need a vFlash card not a standard SD/SDHC
card? From Wikipedia:


   To take advantage of storage greater than 256 MB on the iDRAC6
   enterprise, Dell requires that a vFlash SD card be procured through
   Dell channels. As of December 2011, Dell vFlash SD cards differ from
   consumer SD cards by being over-provisioned by 100% for increased
   write endurance and performance.[21]

might explain some of what I am seeing.
