No, with 2 drives offline in a RAID 5, the data is gone. If neither of the offline drives ever show any status (I.e. they are completely dead), then there is nothing you can do (except professional data recovery, like DriveSavers). You need one of the two disks to show a foreign or offline status. Power down, reseat both drives, power on and see if you see a status for either drive on the PD MGMT screen.
Hello, I have a Dell Power Edge 2900 with a Perc 6/i controller version 1.11.82-0473.  The display shows error "E1810" fault on HDD 2 and HDD 4.  The two bad drives are blinking Orange. The controller is configured in raid 5 and shows the Raid status as offline.  Under "VD Mgmt" 2 hard drives are showing missing.  Under "PD Mgmt" just 3 are showing online and the other two are not showing up at all.  Since 2 of the drives are missing, can I rebuild the array?  Any help on how to proceed would be greatly appreciated.
