Drives dropped offline (missing) RRS feed

  • Question

  • Hi All,

    My first major foobar since the beta. WHS has been fine for ages and today 2x drive declared themselves missing.

    160gb for sys and D: and 3x 750gb in storage pool. Typically the disks that went missing had the majority of the data on. Both can be read with a usb converter and i copied the data from the less full drive back to the share.

    The disks are good, the bios sees them but WHS doesn't. If i usb them they show in the storage tab of connector.

    I've tried fdisk, diskpart and whs still doesn't see them. I'm wondering if WHS has put a flag on the disk marking them as bad even though they are still good.

    Any thoughts,
    Thanks
    Tom.

  • Spooky, both drive are identified correctly in the bios but they're not seen in windows. I put a sata card in and bunged the drives on that. They are both fine, one's been added to the pool and i'm copying data from the 2nd. When that's done i'll add back into th pool.

    Thanks
    Tom.

  • Hi Tom,
    how do you mean, WHS doesn't see the disk?
    You removed it already from the storage pool, and it is visible through normal disk management on the same server?
    If you say "diskpart", did you follow the procedure outlined here?
    If the disks are dropping frequently are not broken, there must be something wrong with either cabling, connectors, drivers - since I never have seen an internal disk dropping out if it wasn't broken on now at least 4 different systems over time. Or did you change Power Management settings, like allowing the disks to spin down after a certain time?
    Best greetings from Germany

  • Nope, none of the above. I did a restart of the server and it came back with the disks listed as missing. I checked all cabling, nothing had changed as i use sata cables with the locking clips.

    obviously there were loads of errors in the status, ie backup service stopped, repair database, file conflicts etc. I removed the drives via connecter and ignored warnings about data loss. The drives removed ok and most errors resolved themselves. As i said the data was accessible on my xp desktop via a usb converter. I plugged one drive into the server and added it as a standalone disk via diskmanager. I gave it E: as the drive letter. I copied the files to server/shares and all went well.

    Once it was empty i wanted to add it back to the storage pool so i reconnected it and booted WHS. It was seen in the bios but in whs via RDP it was not seen by disk management or storage management in the console. I fdsiked it in DOS then followed your diskpart instructions. It's still not seen. I use diskpart often to allign stripe offset etc.

    I downloaded ES tool from the samsung site and it passed all tests. I'm now low level formatting it, which will take ages. Once it's done i'll try again.
