Dynamic Disk reports as Missing under Disk Manager

[kwei]

I have 2 identical disks that I'm using to mirror each other. The second disk is showing up as missing. If i right click on the DISK, I can select "reactivate disk" but I get an error message that reads "the specified disk cannot be located" (oh how intuitive). All it will then let me do is hit ok to close the error box. I have checkdisk scheduled to run on the volumes when it reboots, but I'm not sure that will really help since its the entire disk that is missing, not just one volume. Anyone have a suggestion? I am very wary of letting this thing stand on one leg while this disk is down! Thank you much,

Justin

What type of disk is this (SCSI, IDE, Other)?

Dose the controller see the disk?
Do you know if the disk is good? Try it on another server.

As 2D said does the controller see the disk? If windows reports the disk is missing - then its very likely the disk is missing. (ie. no connection, no power, or faulty)

Yes, windows "sees" the disk, as in if I am in disk manager it can find it, and even breaks the disk down into the partitions that its supposed to have. On boot, the system picks it up quickly. It is an IDE disk. I'm guessing its probably just faulty, but want to make sure before I swap in a new one as this one itself is new. What would your advice from here be? Thanks,

You're in fairly good shape; you haven't lost data yet. Break the mirror. Repartition the disk. Recreate the mirror. If you can't repartition, then consider replacing the drive.

Ok, here is where I'm at. I broke the mirrors, right clicked on the disk that was showing up as missing and told it to remove it. It is now not showing up in disk manager at all. If I right click on "disk management" I can get it to refresh, rescan disk, or restore basic configuration. Doing the first two dont help my situation (tried each a few times). The later, I'm not familiar with at all and am wary of at the moment. If I goto select it I get a warning stating "WARNING: This operation will overwrite your disk configuration information with a previously saved configuration. Currently defined drive letters, volume sets, stripe sets, parrity sets and mirrors may be lost depending on the previoulsly saved configuration. No partitions will be created or deleted by this operation, but any changes you have made during this session will be lost. Do you want to continue with the restoration?" Yes or No option. What you guys think?

One other thing I should throw in is that when I initially built this system, I had this disk show up as missing. It happend right after I built it and started creating my mirrors. I assumed I had tried to do something stupid and it was just operator error. I then just decided to rebuild the machine since I wasnt familiar with that error and I couldnt find the fix(reinstalled OS and all other apps). I'm still thinking maybe it was operator error, but probably not...It works initially, then dies...
