My Asustor AS-304T was working fine till few days ago, drive 3 missing.

This NAS only boot less than 6hrs a week.

- upgraded firmware to the latest after it happened.
- Replace same volume same brand hdd, still does not detect.
- Rebooted several times
- Disconnect power cable for more than a day

how to resolve?

Someone facing the same issue after warranty period, does it mean most Asustor NAS will die on us too?

I was highly recommending friends to get Asustor NAS. After this episode, afraid it does not lasts after warranty period. Looking back at my usage, this NAS should last years....

This happened to me also a fortnight ago but I have an AS7004T which is a few years old now.

I upgraded my raid 10 array from 4x WD RE 1TB disks, one at a time, to WD GOLD 4TB and expanded the volume. Everything fine for a week then:

[Disk] Disk in slot 3 was removed.
[Volume] Volume 1 is degraded with 0 faulty disk(s).

I pulled out the caddy for disk 3 and replaced and observed error log (these all have identical time stamp):

[Disk] Disk plugged in to slot 3.
[Volume] Volume 1 recovering slot 3 disk.
[Volume] Volume 1 is degraded with 0 faulty disk(s).
[Disk] Disk in slot 3 was removed.

Obviously I didn't remove the disk. I've tried a number of times. I've also bought another WD GOLD 4TB but the same thing happens so unless both disks are faulty, which is unlikely, it must be the NAS.

I did however upgrade to the latest ADM 3.0.4.RCQ1 just before this happened so I wonder if the ADM is to blame. Anyone else had a "[Disk] Disk in slot 3 was removed." or similar error?

Hi,

Having exacly same problem with my as-602t. After ADM update, my disk are removed and the RAID get degraded and finaly the NAS hangs.

What a mess!

Hi, any news?
My new as1004t v2 randomly, but always during high usage, disconnects disk 3 from my raid 3.
The hdd simply disappears, but after a restart it reappears without errors and start resynching...

It could be a disk error. After re-sync done, you can do disk scanning to check.

Hi,
disk checked and no errors found.
Today the same hdd, always in bay 3, disconnected without errors, now is reconstructing the RAID 3.
Since I have bay 4 free, can I move this hdd from bay 3 to 4?
I suspect the problem lies on nas...

Yes. But it's better to power NAS off first. Then move bay-3 to bay-4. Power NAS on.
