How would I reinstall the System Drive if it fails? RRS feed

  • Question

  • I am really getting into WHS lately.  I now have about 15TB being stored and duplicated.  I like this because its taken much of the load off of my main machine. 

    Anyway, I was wondering -- what happens if the system drive fails?  I have seen some people post here that you just remove the bad system drive and put in a new one.  During reinstall, I am supposed to see an option to repair.  I do not see any official guides as to how to do this, however.

    I am wondering if someone could please post some sort of guide with pictures on exactly how to do this process.  I would greatly appreciate it.

    I don't know of any "guide" that specifically explains it (although there are Technical Briefs that may have it somewhere and even if they don't, it's a good read to get a better understanding of WHS).  As you said, you replace the system drive with a new one (preferably of the same type, SATA or PATA), then boot from the DVD.  Then, if necessary, supply whatever drivers are needed in order for WHS to see all of the drives.  Once you do that, you should have 2 options:  New Installation and Server Reinstallation.  You would want Server Reinstallation.  It will install WHS, then, during the final step, it will rebuild the tombstones.  NOTE:  This process can take quite a while depending on how much data you have and it may appear that it is frozen.  Just let it run.

    My suggestion:  if you really want to make sure you're able to recover when necessary, simulate it now.  (As a matter of fact, that is also something you should do for restoring a backup to a client PC.)  Boot from the DVD and see if you get Server Reinstallation as an option.  If you do, then you should be fine if the need ever arises.  Or, better yet, if you are really worried about it, pull your primary drive and replace it with a new one, then see if you get Server Reinstallation as an option.

    I wanted to test the reinstallation process so I would have a better understanding of it should the need ever actually arrive. I have been running with two SATA drives installed and duplicating files, so there is data on both drives.  To test the reinstallation procedure, I disconnected the primary drive and connected an empty, albeit smaller, PATA hard drive. I booted from the install DVD. It correctly detected two hard drives. I was presented only with an option for a new install. Had the primary drive actually failed, this is not the response I would expect or need.

    As a further test, I reconnected the original primary drive to see if the install program would then detect the OS and give me an option to reinstall.  It did not, offering only "new installation."

    I removed the third empty disk and rebooted WHS.  I received an "Non System Disk" error.

    I have examined the primary drive and all the files appear to be intact.

    Does anyone have any comments or observations?  What have I missed?



    A server reinstall will not be offered, if the setup procedure does not detect the replacement disk as drive 0 (the drive, from which the server boots),if extra loaded mass storage drivers mix up the sequence or if the structure on the other disks cannot be recognized as WHS data (this would include also scenarios, in which you do only not replace the primary disk, but add other disks in the same context to the server before trying the reinstall).
    In your description the replacement if a SATA drive wit a PATA drive may have caused another disk to be selected as boot disk, but not the PATA drive. Sometimes it may help to adjust the boot sequence in Bios accordingly and try again.

  • Thanks alot for the information kariya21 -- I will give this a try.  I have a slightly larger hard drive laying around, and I may just do an upgrade, and try this reinstall at the same time.

  • Here, and in other  posts in this forum, the indication is that to reinstall WHS, one need only boot from the installation DVD and an option to do a reinstall should be presented.  All I am given is an option for a new install.

    I wanted to test the reinstallation process so I would have a better understanding of it should the need ever actually arrive. I have been running with two SATA drives installed and duplicating files, so there is data on both drives.  To test the reinstallation procedure, I disconnected the primary drive and connected an empty, albeit smaller, PATA hard drive. I booted from the install DVD. It correctly detected two hard drives. I was presented only with an option for a new install. Had the primary drive actually failed, this is not the response I would expect or need.

    As a further test, I reconnected the original primary drive to see if the install program would then detect the OS and give me an option to reinstall.  It did not, offering only "new installation."

    I removed the third empty disk and rebooted WHS.  I received an "Non System Disk" error.

    I have examined the primary drive and all the files appear to be intact.

    Does anyone have any comments or observations?  What have I missed?

  • I actually had my system drive fail on my WHS.  I simply did a fresh install, and it recognized all of my data drives, no data lost.

  • Same here: Long ago, on a beta version of WHS, I was also looking for this rumoured "Reinstallation" and couldn't find it. It turned out that a "normal" installation preserved the data found on the data disks.

  • Hi Martin,
    the wording is different, and for OEM hardware it may again be different in their UI, like Factory reset or Server recovery.

    In the German version the options read translated back:
    New installation (this option wipes all out)
    New installation of server (this option preserves the data).
    Not great to distinguish.

  • Hello Olaf

    You may be right, it's been about a year since I did this. I am pretty sure I had the English version back then, the official Microsoft Beta one. I remember that I was confused, and that the option that I chose in the end didn't indicate that the data will be preserved. But maybe there have been two options, I can't tell for sure anymore.

    Greetings from further south ;-)

  • Olaf,

    Thank you for your input. The hard drive boot priority had changed in the BIOS.  I have reset it and WHS is loaded and running.  Thank you.  

    Your description of the failure matches perfectly the conditions existing with the hardware I am using as, in addition to the motherboard PATA port, I have an ATA PCI card installed. I will acquire another SATA drive and then try my "experiment."
