  1. @gprovostThank you for your recommendations. We were able to recover the data. Could you please give recommendations for a good power adapter to purchase in India? Also, we found something local that is 12V and 12Amps. Would that be ok? I assume the higher Amp wouldn't be a problem?
  2. I havent tried that. My first priority is to recover some of my data :(. Is there any way i can connect the hard disks to a desktop and use a software to recover the data? It is RAID5 with 4 hard disks.
  3. Hello Team, I have been using a Helios4 NAS for the last year or so. It had been working great until now. I use 4 Seagate hard disks with 4TB each (ST4000DM004). I have always used a UPS with the device and it was safe. More recently we had some problems with the UPS and I had to connect it directly to the power source. About two days ago, I tried doing an apt-upgrade/apt-update and the NAS came crashing down. It now no longer recognizes my hard disk. After a lot of troubleshooting, we found out that the SATA controller is not recognizing the hard disks. There are times (very rare) where the disks are recognized, but most of the time, it fails to detect the drives and mount the drive. I had used Open Media Vault to configure the RAID5 array. The NAS boots off the Armbian OS from an SDCard (16GB). We tried using lsscsi and it doesn’t detect any drives. OpenMediaVault detects the drives sometimes but other times it does not. But this morning it loaded up all the drives and as I tried to backup the data, it started crashing and rebooting. Has anybody faced similar problems in the past? I have a feeling the on-board SATA controller is not working. What can I do to troubleshoot the problem and look for an easy fix? Any suggestions would be greatly appreciated. PS: I have attached all logs from /var/log and the output of my connection to putty. Thanks, Sandeep Archive.zip putty.zip
