ReadyNAS Pro 6 with 8TB WD Reds
I had an x-raid made on all 6 hdds, I was running raidiator 4.2.x, I had to shares. I made an upgrade from 4.2.x to 6.9.3 but I forgot to back up one of the two shares, is there any way to recovery the data on it?
Thank you in avance.

Thank you for your clear answer, but I think I didn't started the thread clearly. I had onbord the 6 wd red of 3Tb each with the two shares on it. I made a copy of one share and thinking that was all I did the upgrade loosing all the data in the second share. The right question shuld be: Is there an yway to recover them?
Well, it depends on exactly what you did.
If you removed the 6x3TB drives, installed one or more of the 8 TB drives, and then converted to OS-6, then your original array is intact. If that's the case, you could mount the original array as read-only. Just power down the NAS, remove the new drives (labeling by slot), and reinsert the original disks (ideally in their original order). Then power up. When done backing up the data, power down and reinsert your new disks.
But if you did the conversion with the 6x3TB drives in place, then the conversion process would have reformatted the drives, created a different partition structure, and then installed a new file system on the data volume. If you are really desperate to get the data back, you could try Netgear's data recovery software (or RAID recovery software on a PC), but if you did the conversion with the original disks in place I think the odds are very poor - especially if you have copied back some files to the new data volume.

What disks were you using with 4.2.x?
- Wdc wd30efrx-68euzno
Wdred 3tb six of themIf you put the new drives in before you changed to OS6, and you still have the old drives (preferably marked as to location they go in), you could put in a spare drive, revert the chassis to 4.2.x and then install the old drives (with power off).
If you don't remember the order of the drives and have an old log .zip file, you can find out which serial number goes where in disk_smart.log.
Once you have the data you need, use the spare drive to move back to 6.x and then put your new drives back in (again, with power off).
