OK guys I have some news. Have not done anything with the 705, I still have the problem where my replacement 60GB hard drives are not large enough to tag as hot spares to rebuild the raid-5.

I decided that I would try building my "new improved" 4100 using a 256MB ram chip and four 160GB Maxtor drives that I had. My idea being that, once I got this one on it's feet, I can move the data over from the 705, and then try to rebuild the 705 using the "smaller" 60GB drive in the first slot.

So back to the 4100. Installed the RAM - no problem. Installed the four 160's, set all jumpers to Master, turned it on - and I could see the snap formatting each drive - GREAT! As everyone knows, it did not give me 160GB, but more like 128GB formatted. Once it was done, it gave me four separate drives with no error messages.

So then I began to try changing the disc configuration to Raid-5. Everything seemed to be going fine, and the process does complete, but I have a problem that I have seen posted on here in other threads with no real solution.

Once the rebuild is complete, under "View Disk Status" I am seeing:
RAID5 - Large data protection disk
OK Unknown disk operation error.

The shares do mount and seem to be usable, but I am concerned about this error message. In addition, once restarted, it tries to rebuild the raid again.

In the disc log, I have this message: Failed to resynchronize logical set 60000, error -1

I wonder if it really a practicable idea to use the 160GB hard drives. Has anyone actually done this sucessfully?

One last question - would ANYONE be willing to email me the files needed to upgrade to either 3.4.805 or 3.4.807? Perhaps a more recent OS would be more robust and help solve the issue. I can be emailed for this purpose at:
printperfectinc AT aol dot com

I will be happy to report back to you guys if I can get this to work. If anyone has successfully installed 160's into a 4100 I would like to hear from you alslo!

Thanks much!
