You have not lost your data as long you'd did not formatted the disk
Before you go back to 5.2 be sure you have the right pat file
then complete the 6.0 update
put your usb with the expenoboot file in to your server
be sure that you have a screen connected to your server with the via cable restart your server boot with usb
then choose the install/update 5.2
then go back to your computer and look for your server with sinology assistant
choose to manual update and then browse to the 5444.4 pat file and then follow the instructions
Your a star
Got back 3.8TB that I thought I had lost
Cheers
I did the update to 6.0 aswell, I now have no volume (shows 6 unused disks)
I was using SHR on 6x6TB drives in a microserver
Have I lost my data as I cant see the volume? ...or do I just need to roll back to 5.2?
Thanks
