DNS ShareCenter - Troubleshooting a Bad HDD
« on: August 05, 2013, 10:54:57 AM »

    Circumstances may arise where a ShareCenter HDD or Volume may not be accessible or visible from within the ShareCenter web UI or client PC. The following procedure outlines initial  troubleshooting steps that can be used to determine if the root cause is a defective HDD or an issue with the ShareCenter itself.

    Procedure

    • Download a HDD testing tool from the HDD vendor website (e.g. Seagate offers a free product called SeaTools)
    • Install the HDD testing tool on the client PC
    • Power down the ShareCenter and remove the suspect HDD
    • Attach a USB/SATA caddy attached to the PC containing the testing tool
    • Mount the HDD in the USB/SATA caddy
    • Run the HDD testing tool against the HDD in the USB/SATA caddy and note the results
    • If the tests indicate an issue with the HDD, then contact the HDD vendor for a replacement. If the tests indicate no issue with the HDD, then the ShareCenter may be at fault.

    Why Can't I Mount the HDD Directly in My PC?

    • Physically mounting the HDD using the SATA ports in a Windows PC is likely to corrupt the data on the HDD prior to the Linux HDD software activating.
    • Mounting a damaged HDD in a PC may prevent the PC from booting or cause HDD assignment issues.

    Notes

    • Since the ShareCenter format HDDs using the Linux filesystem, a HDD will not be visible by simply attaching it to the USB/SATA caddy on a client PC running a Windows OS. The HDD testing utility will be required to detect the HDD and special software is required to make the volume visible and accessible from the Windows OS
    • In the case of a RAID configuration, each HDD in the array may require testing
    • Don't discount the possibility that more than one HDD is defective (this scenario has been known to happen)
