[Help] TM F4-420 Died and need to save the data

[Archigos]

I bought a F4-420 in June 2017 and know it's beyond support at this point...

The second bay died on me... I confirmed Bays 1, 3, 4 work fine and if I take the drive from Bay 2 and put it in any other bay it will read the size of the drive fine, so I know all of them 'should' be good. It's been like 9 months to a year since this happened and it's just sitting on my desk, but something came up and I really need the data from those drives. I remember when it first died I searched the forum for a long time and found a thread talking about there was a model you can just take the drives from the 420 and drop them into the new system and it'll be fine... however I couldn't afford to make the purchase at the time and can't seem to find that thread anymore so I don't know if it was the 423 or 424 or whatever and I don't want to spend the money to find out I got the wrong one or lose my info, etc...

I have over 40TB of data on there that I really don't want to lose (probably about 60TB of total data on the drives) (4x18TB)

If I'm correct, I know the 423/424 are technically 'kind of old' at this point as well and I don't care about that fact... I just need this to last me a good week or two to get the data off and if it lasts at least 3-6 months (minimum) I can save up for a newer/better model and 'start over' with all the required data and have a new "Long Haul" device as opposed to a temp solution to get me past this issue.

If anyone can confirm, again, I have/had the F4-420 that was on the latest TOS5 that was available at the time 'of death' but I'm unsure which version it was. I need to purchase what I assume is a 423/424 that I can just drop the 4 drives into and 'continue on' like nothing happened. If it helps, the 4 drives were configured in JBOD and I can't remember if it was BTFS or whatever the 'default' was... If there's a way to use Linux tools (in a VM on macOS) to get access to the data I can back stuff up this way and use the money saved towards getting a 'bigger/better' NAS instead and skip this one step.

Someone, please help....

since its JBOD and if you are sure the disk is fine then you can just put the drive in an enclosure and should just be able to read the disk using a linux OS whether its under a VM or not

but yes this is the issue if you didnt plan to have any kind of backups or redundancy for your data

as JBOD treats each drive individually you could probably take all drives out of the NAS, put in a new clean one even if its just a cheap 120gb SSD etc so it loads the OS onto that, then you can put in each drive individually and recognize and access the data

the question is it just a System OS issue, or are you dealing with a physical hard drive issue, if its a hard drive issue then you will struggle

Sorry, not JBOD… I meant to say Non-Raid… It was whatever the selection was so they all appeared as one combined total (as if one drive)

I did talk to an employee via the chat and they claimed the F4-423 was the ‘upgrade’ to the 420 like I thought, so I bought one on Newegg since I had some credit left there so I didn’t have to pay full price out of pocket. Hopefully it works

Based on your description, all hard drives are configured as one large drive with no redundancy, but it's not RAID; it could be JBOD or RAID 0.

None of this matters as long as the data on the hard drives is not damaged, you can insert them into F4-423 to read the data.
