Hi all! I'm hoping you can help me with this error...

I now own both a Snap Server 4100 and a Dell PowerVault 705N. I have recently upgraded the OS to 3.4.805, BIOS 2.4.437, along with JAVA VM. Upgraded each to 256MB ram as spec'd here.

Here's the deal. On the 4100, I purchased it with 160GB Maxtor drives. It was working perfectly. Well, one of the drives failed. You may have seen a previous post regarding the same. So I purchased the 705N with 40GB Drives. Now, I needed another 160GB drive for the 4100 and 4 more for to replace the 40s in the 705n. So, I purchased the EXACT same models of Maxtors as were in the 4100 to begin with. I reformated each disk and configured each for raid 5. I did this via the web interface and not through the debug menu as specified in the field service guide.

Everything is working fine on both units, EXCEPT when I look at the disk status, it shows RAID 5, "Unknown Disk Operation Error"--on both units. My jumpers are all set to Master on the drives. Everytime I reboot it tries to rebuild the RAID and gets to somewhere beyond 30% before it goes to the error.

I have not run a REPAIR ALL ERRORS because last time I did I lost a drive while running in degraded mode--and we all know what hat means. This time, because I can copy all my data to the second unit, I could simply reformat everything and rebuild the raid, then copy it back.

Any suggestions?
