Don't know if it's better to post here or in the Troubleshooting form so I've posted it on both.

I have a EX-470 that I'm added 3 x 1TB drives internally, a external RAID tower with 2 x 1 TB and 2 x 1.5TB drives, and added an external 1TB and 1.5TB usb drives. My total disk space is about 11 TB of which I'm using about 5TB so far.

Based on storage monitoring program I have, none of my data seems to be stored on the original WHS 500GB harddrive that came with the unit.

After reading all the articles about upgrading I already upgraded the memory to 2GB Corsair dual memory with 4-4-4-12 latency. This configuration has been working great for a couple months now.

Now the probleme, I just recently upgraded my cpu to AMD Atholon LE-1660 2.8GHz 45W processor. I had read the articles about upgrading to LE-1640 and saw a few posts that indicated that LE-1660 would work so after not finding a LE-1640, I bought a LE-1660 from newegg and the upgrade seemed to go well except for the following.

Problem 1:

The system works but I'm having a problem with WHS Console and the fact that the unit locks up after a while.

It's weird because once I turn on the unit, it allows me to see and modify all my shared files on the unit and I can remote desktop on the server without a problem. However, if I try to log on to WHS Console from a remote computer or from within the remote desktop of the server it takes a little while and then once the WHS Console does come up it seems almost locked up. I can move my cursor all over the WHS Console selecting things without anything happening. If I wait about 10 mins or so, WHS Console finally starts to respond. When it does respond, it responds faster now than before I did the processor upgrade. Everytime, I reboot the server the same things happens.

Problem 2:

After a while, say about 30 to 40 minutes the server seems to lock up. It kicks me off any connections I have (i.e., it kicks me off remote desktop, WHS console, or losses connection with the shared files) and then it tells me that the server connection is not available. Additionally, when I look at the lights of my USB harddrives that are attached to the server, they seem to be lock also because they stop blinking or moving (which the always do under normal operation).

Proposed solution:

I am think of trying to reistall the OS on the WHS server. The problem is that I'm afraid that if I do it will wipe out my 5TB of data files.

Questions

Is there a way to re-install the OS without wipping out the data? Is it possible to remove all the drives except the original 500GB drive (the one that came with the unit when I bought it), re-install the operating system on the WHS server and then re-install the other drives and have them recognized by the WHS without trying to format the drives and losing all the data.

Any other ideas would be helpful.

Thanks.

I forgot to mention that there does not seem to be a temperature issue because the CPU seems to running at about 38C and I've even put a fan in front of the unit that keeps the temp down to 32C. Thanks again.

As for re-installing the OS: You can do this with a RESTORE. Be careful to RESTORE and not do a Factory Reset and your data will be retained. (The Factory Reset will reformat all the drives.) You do NOT need to remove the other drives to do this. That said, I am not so sure this will resolve your problem, but it is probably worth a try.

Incidentally, it is absolutely normal for the original EX470 disk (the "system disk in Slot #1) to have no data stored on it. Unless the other disks are at (or very close to) full capacity, this disk is only used as a "landing pad" for the extender logic.

As for temperatures: I suggest you install the MSS Fan Control Add-In and crank up the MSS fan speeds a notch or two.

These are the same symptoms I received trying the BE-2400 dual core, very fast when it was running but locked everything out every 30 minutes or so and it looked like it was still running but no connections could be made. The console was locked. I'm afraid it will do no good to reload the software, it is hardware related and I'm afraid your machine will not take the LE-1660. You can keep trying to run it and I'm pretty sure it will get better the more it runs but it will probably never be stable.

Have you opened Task Manager to see what the CPU utilization is? I'm currently troubleshooting a situation where the HomeServerConsole.exe is utilizing between 8%-15% of the CPU(s) on a continual basis. I've installed the Systernals utility ProcessExplorer and it is shows the .NET function ClrCreateManagedInstance+0x8aa4 located in mscorwks.dll is where the CPU is being consumed. After Googling this I found several reports that seemed to point to multi-core processors being the at least part of the problem. Further, it was reported by one person that Microsoft said that it was a .NET 2.0 SP1 problem and would be fixed in SP2.

I'd be curious to see if you see the similar behavior.
