Hello dmitry.pronyaev, So the drive that you have is not listed in the support matrix for your MD. Is there a Dell part# on drive HUC156060CS4204? Was all the drives purchased with the MD1220 or did you purchase the drives after getting your MD1220? With MD systems they generally will need to be HDD with dell Part# on the drives in order to be seen and work correctly. Please let us know if you have any other questions.
Hi all! I have MD1220 (connected to MD1200 that is connected to MD3600f) with 10 Ultrastar C15K600 (HUC156060CS4204 firmware EK11 ) HDD. MDSM tells that "Status: Incompatible, Cause: Firmware error trying to use physical disk". So technical support told me to update disk firmware and gave me a link to package of firmwares. [URL] this link doesn't contain firmware for my disk - I have HUC156060CS4204 but link contains HGST_HUC156060CSS204_EJ24.df (model name differs in 1 symbol: SS204 instead of S4204) and MDSM says "This package is not compatible" :(  May be you can tell me where to find suitable firmware to flash it with MDSM?
MDSM 1220 and HGST Ultrastar C15K600 (HUC156060CS4204)
