awediohead Posted November 9, 2021 Share Posted November 9, 2021 So I recently added another 4TB drive to my array and some weird stuff started happening with it not mounting - and various other errors. I won't detail them as they're now resolved. The point is that while all this was going on I searched here and it seemed that my Marvell chipset PCIe to SATA 4 port card was the likely problem since the new 4TB drive was the only array drive connected to this card - the other device connected to this card being an optical drive. So assuming the whole parity check thing would end badly with the Marvell PCIe card , I ordered a new PCIe card (Chip JMICRON+JMB582) - BUT to my surprise once the whole process of formatting and parity checking was finished, the new drive lit up green for 'normal operation'. So the question is, can I simply swap out the Marvell PCIe card for the new JMicron card when it arrives tomorrow? Will that muck up the array at all - can't see why it should just double checking? And should I? I mean in an, "if it ain't broke" sense? Right now, there's nothing on the new drive so I'm wondering if "Marvell" related problems - the reason they're so actively recommended against here - might only start happening once the drive is regularly having data written to it and being read from as part of the array?
