diskcrashThis is the 3rd time a disk has crashed on Volume 1 of my Synology CS-407 NAS Server. I am wondering if it’s the Synology or just a faulty disk. This is the 2nd brand new disk to have gone into the NAS in many weeks. Just this last weekend I prepared the disks in the NAS, which took hours. By preparing the disk I mean running some software called DISKWIPE that writes #’s to the disk to clear it.

So far in all the disk setups (RAID0, RAID1, RAID5 and BASIC) it’s has always been Volume 1 – Disk 1 that has failed. Typically this is the disk that contains all my video, music and photos. 🙁 Thanks goodness for backups

    Hi Mike,

    I am Edward from Synology. Just saw your post and am really concerned about your case. Have you submitted a support ticket at http://www.synology.com/enu/support/form.php?

    I do hope we can be of help.

    Thanks,
    Edward

    Hi Edward,

    I haven’t logged a ticket since I am not sure if it’s the Synology at fault. I do trust the hardware, and have done enough searches on the Synology Forum for this problem and have not found similar cases.

    Both disks that failed were brand new (bought at the same time from the same online shop and they were Seagate Barracuda 7200.11 500GB drives).

    The fact that both of them have crashed in the Synology on volume 1, but also also on volume 2, prior to me preparing the disks, has made me wonder perhaps it’s the disks. Maybe a bad batch. I am waiting on a Samsung HD753LJ 750GB drive, which I ordered on Friday (one that is recommended on your site), and if it suffers the same problem then I will draw my conclusion that it must be the Synology and definitely log a ticket.

    I have the latest firmware installed – DSM 2.0-0728 – (if that makes any difference).

    I have prepared the 2nd disk again, and run the SMART Extended Test on the drive and it’s come up as successful with no problems.

    After my latest hard disk crashed (samsung 750GB), I was convinced there was something wrong with the actual CS407. Anyway I did a bit more digging and came across the same problem happening for a few other CS407 users on the Synology forum, and for them the problem has been the SATA Controller on board or the SATA cable, so I replaced my SATA cable and rebooted and the “crashed” drive is now working again. (Luckily I didn’t trash it, like I did with all the others). I rerun an Extended SMART test, and the disk is fine. No errors.

    I have now fired up my old DS106e NAS, installed one of my free 500GB disks and it too is working fine (this was one of my original crashed disks). 🙂 I think I will use this as a back to the CS407 until I am satisfied it is working.

    I am glad to see the firmware for the DS106e is like the CS407, although it’s a bit disappointing that there is no file station.

    I know it is an old thread, but I have exactly the same problem – 2 disk crashes and I replace them with new and now it says Disk 1 crashed.
    I can’t see any data !!!

    I will try to replace the SATA cables on disk 3 and 4 – it’s the “bad” disks…..
    Is your (Mike) cs407 working now after the new cables ???

  5. blank Mike says:

    Synology were very kind enough to send me 4 brand new cables and I have not had any trouble since. I still have a mix of hard disks in my CS407 but they are now working fine!

    Once the cables are replaced, you’ll find you will be able to see the existing data on the drive, so don’t go and format thinking there is no hope!

    I have a CS407 and have had the same thing, Mine isn’t fully populated and drives 1 and 2 fitted, but I’ve gone through 2 drives sisnce christams, both 1TB, both drive 1, luckily the 2nd drive was formatted with no data on it. I’m runing my discs in basic mode for the time being.

    I’ll try another lead and see what happens.

  7. I have the same problem, my CS407 volume1 is damaged after disk 1 and 2 are new. please help me!
