Hi there,

Is there a way to access the data from a TOS4 Ext4 drive through TOS5 when the drive is installed in a F4-442 (or a USB attached D4-300)?

I upgraded all my hard drives, installed TOS5 and want to copy my data back over from the old drives. When I insert the HDD into the NAS, it detects the drive but can't see the data folders. I also have the D4-300 DAS attached via USB but when inserted, it can't see the data either.

Would prefer to be able to copy the data directly from drive to drive vs. running a virtual machine/Linux on my desktop to retrieve it.

Because the system partitions of the old and new hard disks are different, inserting the old hard disk with TOS 4.2 installed before may not be able to mount.
Please try to insert the old hard disk, and then reinstall TOS 5.
