The following 3 NAS data loss problems are best addressed by links to these two previous posts: https://harddriveman.com/2017/07/01/hdd-and-nas-data-recovery-required/ and https://harddriveman.com/2017/04/06/synology-nas-data-recovery/.
My Synology DS1813+ NAS (data sheet here) is showing that I have a volume crash and that it is unable to use the volume. I am unable to back up the data as there is 25TB+ across 8 different sized disks and I don’t have anything that will hold that much – also I have no idea how I would back up the data even if I could. I don’t mind losing some data but I’d like to salvage as much as possible as this includes a lot of both personal and business files collected over several years – is this doable or have I lost everything?
I had recently removed and replaced a 2TB disk with a new 8TB disk and the NAS was going through the repair process. At about 20% my property had a power cut that turned the NAS off mid-process. When I powered it back on the beeping started and after the NAS went through a checking process a message appeared stating “Unable to use this volume. The data in the volume may be crashed. Please try to back up the data before removing the volume.“. I’ve tried rebooting the NAS but this hasn’t helped.
My external NAS hard drive was dropped today from approx 3ft. It’s a 2x2Tb WD passport ultra. Initially my computer allowed me to access the data once, but has not allowed me to since. My laptop will recognise that something is plugged into the USB port but will not let me access it. When I do, it gives “I/O device error” message. Occasionally, once in the 10mins I had the drive plugged in, it made a beep noise. It does also take a while for the laptop to recognise that the drive is connected.
I have two external NAS hard drives that do not appear on my Computer when they are plugged in. It’s been years since I tried, but I know there are documents there. Movies, pictures, sound effects, etc. one is 1tb, the other is 2tb.
Synology NAS, set up with SHR. System notified me that 2 separate drives were failing (not failed), so I purchased 2 new drives and started using the onboard system to transfer one drive to another. During this process the system crashed, taking out the system partition and making the system unreadable.
I contacted Synology who have done what they can, but have advised me that any further action on their part could lead to data loss, as the system contains all out photo’s from before my daughter was born, all our documents (and also all our videos and TV recorded programs) we are not willing to potentially loose that data.
The DS2415+ system currently has the following config:
Bay 1: WD 6TB Red
Bay 2: WD 6TB Red Pro
Bay 3: WD 4TB Red
Bay 4: WD 6TB Red Pro
Bay 5: WD 3TB Green
Bay 6: Empty
Bay 7: WD 3TB Green
Bay 8: WD 2TB Black
Bay 9: WD 2TB Black
Bay 10: WD 2TB Black
Bay 11: WD 2TB Red
Bay 12: Empty
The system advised me that drives 3 and 7 were failing and I have already got 2 new WD 6TB RED Pro drives ready.
The engineer also informed me that all of the smaller drives (Bay 7-) are showing considerable SMART failings, so as part of the recovery process I would like to consolidate my data onto Drives 1,2 &4 and the other 2 6TB Red Pro drives that I have. I understand that this may be insufficient and am ready to purchase additional drives.
I live in Preston, Lancashire, this has already been down 5 days, so I am looking for an urgent turn round, but also one which I can afford. Please contact me, so we can determine the best next move, and also give me an idea of the potential cost.
Authors Note: In all cases of data recovery from Synology NAS systems, my recommendation is to take the system straight to the experts – in this case Data Clinic.
Data Clinic are a UK wide data recovery company who specialise in RAID and NAS hard drive recovery. Their NAS recovery page for Synology RAID hard drives can be found at http://www.dataclinic.co.uk/synology-nas-data-recovery/
