I have 3 300Gb SAS drives running raid 5. It's almost out of space. I have added a new matching drive I can see with the MSA$UTIL show options. The new drive is disk 4. Can I add it to the existing RAID 5 without hurting the data and get more free blocks? I do not know how this works. 2. The firmware on the new drive is HPD2. On the older ones it HPD5. Will that matter? 3. My cache battery is dead can I safely work on these drives? Here is what I see in MSA:
