@michaelmurphy I ran a ubuntu scan on one of the drives,

 

It found so many partitions I lost count, none I checked contained any reference to my main files so its looking like a lost cause for this corruption

 

One of the partitions I found some folders listed but it was just the contents of an old backup zip file?

@skewt - it did pick up your disk:

 

Disk /dev/sda - 4000 GB / 3726 GiB - CHS 486401 255 63, sector size=512 - ST4000DM004-2CV104, S/N:ZFN1M6XW, FW:0001

 

But doesn't look good I'm afraid for recovery:

 

NTFS part_offset=100921344, part_size=4000768327680, sector_size=512 NTFS partition cannot be added (part_offset<part_size).

 

I don't know if you had anything important on these drives but to be perfectly honest it looks like you've lost everything. If you had important data it'll be best to take them to a data recovery specialist however this is many $$$.

 

Have a look at re-purposing this computer with UnRaid: https://unraid.net/ - you should be fine to use the same external array but if you can fit all the drives internally this will be the better way to go.

 

How UnRaid will work it is you have 1x Parity + the rest are data (added together). I can see there you have the following:

1x 6tb - Parity
2x 4tb
1x 2tb
1x 1tb

 

Your largest drive (or equal to largest) always has to be parity so your 6tb drive will have to be parity in this case. If you have limited slots in your server it is best to have this drive internally mounted and the rest of the drives can be external still. This will mean you'll have 11tb to play around with and any one drive can fail without data loss - if you need more storage down the track you can always a drive baring in mind the parity always has to be the largest disk. UnRaid itself boots off a USB flash drive and can run Plex and many other apps (Sonarr, Radarr, NZBGet etc) in Docker containers.

 

Combined with this, have a look at setting up CrashPlan: https://forums.unraid.net/topic/32220-container-crashplan-amp-crashplan-desktop/ - I have my UnRaid server backup nightly and it has come in handy a few times.

 

Feel free to shoot me a PM if you require some help if you decide to go this route. There are heaps of YouTube videos and guides with setting things up.

Thanks for that, I plan to replace the system with one I can load the drives internally and try ditch this USB enclosure (currently it’s an i5-7200u mini pc) so will try do unraid then

Iam having luck using photorec but makes it hard to sort with loss of file names.
I did manage an export of file information from plex so might try create a parser to rename them as a project

A word of caution. You may see this drive bay holder thing around.

 

Click to see full size

 

It is hopeless at cooling. Even with a 120mm fan in the front screaming away, the middle 3 drives get up into the 60s very quickly and one side not far short of that, I didnt leave it to see what they got to. If you do get those, it would be 3 drives max and since it takes 3 bays, might as well use something else.

 

Also, 6 post sata cards always seem to have 3 of them running off a port multiplier, so the performance is trash. I am yet to find a reliable way to add more ports to a computer that isnt a server type HBA card with cables. The 5 port ones are directly connected to a controller but its slow.

 

I have different orico external drive cases I uses in the past. One quite old, another that looks identical externally but has a newer chip that does UASP so should be faster. It isnt. THey both suck. Never had corruption issues that I could blame on them, but they would often just stop working and need a USB unplug and replug to get going again - still were in device manager but just not working. That was on motherboard intel raid and an addin card that I think was NEC

I have experience with Drivepool.
It does a fantastic job and I seriously doubt it was the cause. Typically, if Drivepool detects any serious issue like a missing disk, the pool immediately goes read only to prevent further problems.

I'm with you thinking this is likely caused by the raid controller.

Stablebit support has always been great, so you could contact them and ask if they have seen anything like it.

For anyone unfamiliar.
Drivepool is pretty foolproof, it doesn't do anything terribly funky, it just stores files on NTFS volumes and presents a virtual disk with everything in one place.
It does also manage files disk location and duplication.
If you pull a disk and put it into another machine, all the files on that disk are fully accessable.

Sounds like a software RAID controller to me...  ;)

My 2 orico 5 bays look identical, had the same listing and were different. They have 5 trays on them and look like that 4 bay but taller and 5 bays. Both are non raid ones because I dont need that sort of drama in my life. They ran my storage spaces "ok" until I moved to a port mulitplier esata based solution because of the orico going to sleep and never waking up.

 

That port mulitplier carry on lost me the data on the storage space because of windows updating changing the controller card driver for one that didnt support multipliers and me going "where is my storage space?" opening the control panel and being offered to upgrade my storage space when all the drives were not present.

 

Strictly sas cards and breakout cables now. No issues at all with drives disappearing, going to sleep, reacting funny etc. Total reliability.

Well things are looking up,

 

I can recover the files with Photorec and I have created a parser to rename those files back to the original name and place them back in the existing locations (Plex export data) 

 

 

 

While this system been running flawlessly for over 2 years I will look into replacing the mini PC with something I can load the drives internally

 

DrivePool has been great since I started using it, so much easier than trying to find free space on a drive for your media.
Made managing plex on windows a lot easier

AMD's 850/950 Southbridge with AsMedia PM has the same problem.  Also UASP is disabled pre W10 even though the controller supports it.

 

Re: sleep state - this is a known issue on 105x chips.  Fixed by flashing fw with sleep timeout disabled. I can link you to ASMedia's flasher if needed

 

 

 

As a simple 2.5" external case Orico seem OK, but yeah I prob wouldn't bother with any more complicated lol

Are device id's same? If that's the case ( pun intended) driver issues are pretty much guaranteed.

 

 

 

Almost like one enclosure  is a cheap knockoff...?

The power supplies in these devices are notoriously under-specced.

 

It would not surprise me to see that a fully populated unit would cause the PSU to drop out of spec and low voltages could cause data corruption on writing.
