Difficult at best. All 4 drives from the same purchase, mounted 2 to the
3.5" adapter, and all 4 shoved into a front panel-less drive cage below
the floppy slot in a huge tower case about 17 yo. Rather than blame data
cables, I'd start by changing out the power splitter cables, this psu
doesn't have near enough sata power plugs for 7 drives, only 1 of which
is spinning rust. But I'll have to order some more as I think I've only 1
spare left from building it. But I just checked, all splitters left are
old 4 pin molex's. I have enough cables to change all the data cables,
black ones of course since the pretty red ones are 3 year cables,
maximum.
And I'm out in small town america, so I'll see what amazon has. Maybe
they csn simplify the mess I have for power cabling now. 4 pack of molex
to sata splitters, s/b here Monday.
Thank you Andy.
