I've tried migrating to the new alpha, but got this error instead:
"We've detected errors on the hard drives (6), and the SATA ports have also been disabled.
Please shut down your DS3615xs to replace or remove the hard drives and try again."
I'm using the same SATA configuration as 6.0.2 loader (SataPortMap=4), and I also tried SataPortMap=1, SataPortMap=5 and SataPortMap=6.
No luck.
I´ll try again later today using the forced mode.
