Hi Joe, Jason, and others following the saga of my EX490 system disc failure and replacement.
The new WD drive arrived and was installed in slot 0 without incident. I performed a Server Recovery (NOT Factory Reset, as I hoped to recover my data folders) and succeeded on the first try! I credit what I learned during the pervious Recovery, but even more valuable were a couple of guides published elsewhere. In particular, I found this post on mediasmartserver.net to be very helpful:http://www.mediasmartserver.net/wiki...X490_and_EX495
-I copied the entire Server Recovery disc from HP onto the HDD of the host PC, and ran the executable from there rather than the CD-ROM. I bombed at step 2 or 3 multiple times before doing this. Don't know why that would make a difference, but suppose faster and higher sustainable read rate from the HDD helps.
-The host PC for recovery was an older Dell running XP service pack 3. I uninstalled all the HP SW from it first (Media Collector, Console Connector, etc.).
-I directly connected the host PC and the 490, with no other devices. (should use a crossover cable but most NICs now can auto-negotiate this if you use a standard RJ-45 cable). In theory it will also work through a switch/hub, but NOT a router as the 490 seeks an IP in the 169.37.37.xx range from the PC during recovery and most home routers are using the 192.168.xxx range. No DHCP device should be on the net with the 490 and the host PC!
-The timing of pushing the front recessed "reset" button is critical. Have the paperclip inserted but not far enough to depress the switch when you power up the 490. As soon as you see the "violet" (I'd call it PINK, mix of red and white) flashing status LED, push the paperclip in ONCE.
-Once successfully started, the Recovery process can take some time, so don't be alarmed if the "progress" bar seems stalled at several points in the recovery. (Mine took close to 2 hours).
-Once you reach success with Server Recovery, and the 490 is connected back on the regular network, you still have to wait while all the updates are downloaded and installed. (Mine took over an hour).
-At that point the server will be able to deliver files, but it will probably take a full day or more before the file-duplicated folders are completely rebuilt and are fully redundant. You'll hear continuous drive activity and the CPU and discs will be warmer than usual.
-The new WD drive is hotter; SMART reports it at 43C most of the time, which is borderline "warm". The slot 1 Seagate runs 38-39C.
-I found it necessary to reinstall Connector on the PCs I want to be able to run MSS Console on. The previous install was not recognized by the 490 (dont know why). Don't use the supplied CD-ROM but pull a fresh Connector install from the server "software" folder as it is the most updated version.
-MSS attempted to recover the PC backups but failed. (Ae they all on the slot 0 drive?) I lost them all but new ones are now populating the backup history, so nothing was lost.
One PC refuses to run Connector, still hacking at that, another won't (yet) autobackup overnight, so I've forced a manual backup for now.
Twonkymedia went bezerk (again, see way up this thread) so I had to disable it. Was hogging 99% resources and bogging everything down. I use mapped drives for access and streaming by media extenders and PCs so this was no loss.
Media Converter was also disabled; don't ned the low-rez versions and don't want the background CPU usage (the 490 horsepower and memory is a bit light, compared to the 495 IMO)
Joe- I don't think there is any value in manually precopying any files to the new slot 0 system drive before installation. I suspect the Recovery process formats the new disc
, sets up the OS partition (about 20GB) and then installs the OS. Any duplicated files recovered from other discs will then be rebuilt in a second partition using all the remaining space. (you don't get to see where files are on the discs, however, as they only appear as folders in the user interface. I think if you RDP into the 490 you can "explore" the physical file and folder structure on disc, but my mantra is "look but do not touch" while inside the 490 using RDP as the WHS software manages everything.)
Some brands of drives apparently benefit from being formatted in a PC first. I just threw the WD into the 490 and immediately started Recovery.
In theory, I believe if you suspect the sys disc is in trouble, you can "remove" it in Console, which might put non-duped files from that disc elsewhere... in my case disc 0 more or less failed before I could exercise the option of "removing" it from the pool before physically removing it from the case. But file duplicaton had been on so everything except the older PC backups is intact and we are (almost) back to normal operation.
Yikes, long post...
I am not a PC or software maven, so if I plugged through multiple Server Recoveries and replacement of the OS drive, anyone can. Just be patient and follow the cookbook steps. My thanks again to those here and on the mss.net boards for the help.
