Hi,

i have a F4-220 and tried several times to upgrade to TOS5, but i have much data on the drives.

The only way i found not loosing data was:

- Keep connected 1 SSD (master/boot)
- Disconnect the other 3 HDD (slaves/data)

After the initialisation, i tried to plug the 3 "slaves" (one at a time, with reboot after each one), but i get a "volume corrupted" message, and it seems that 2 HDD shows the same volume number.

In TOS4 i have no conflicts with them. Even when i downgrade to TOS4, they work correctly.

I apreciate any help to this issue.

I really don't have other option, since i don't have other 12TB HDD to backup all data :/

Regards from Portugal

what is your previous TOS version before you update it to TOS 5?

4.2.39

Try to plug in all your drives, do not separate them as master, or slaves, and reinstall TOS 5 again.

It wouldn't delete the data from all drives?

Normally, it wouldn't.
BUT when you are prompted to create a new storage pool or volume during the installation, you need to stop and quite immediately.
