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.
