Ok, yesterday after having deleted everything on sda, I was able to boot gentoo stage 3, on sdb3 and partition and format sda, after a reboot the disks was syncronizing, and I postboot to initialize portage.
When the syncronization was done, I corrected fstab to include md14, emerged hdparm and rebooted.
That was the last time I had the mini running
On reboot the blue linkstation flashes for some time, then shuts off, after 5 to 10 sec. the single blue led on the other side of the linkstation lights up, and a couple of seconds later the linkstation restarts, and so on.
I have tried booting with both drives mounted, and with both drives alone, always with the same result !
Does anyone have an idea what can be wrong ?
I'm fairly far up the creek right now and could use some help !
