I meant 3 different tries with WD & 2 different with Seagate.
The first try with that Linux tool made the WD totally unformatted / unpartitioned.
Incidentally, as a last ditch effort, I put the WD disks back in before going to bed, it started blinking 4&5. This morning nothing was blinking. But the MD600 did not show up anywhere.
If so, try inserting a Disk into that for a little while, maybe 10 minutes or so then take it back out again.
That 10 minutes should return the Disk to "virgin" status and inserting it into the MD600 should then trigger the MD600 to perform the necessary formatting.
I had a similar problem when I got my MD600. I had 2 WD drives from as NAS. The MD600 would not recognise them. The solution was to format them to FAT. Once I'd done that and put them in the MD600 it started up and did its knight rider thing.
Good luck.

When did you buy the MD600? It strikes me that if it's still under warranty you'd best get it sorted by the dealer than trying a repair that is potentially temporary.
