Replace original removed HD after failed disk upgrade?
Hi, We have a ReadyNAS Duo which had 2 x Seagate 500GB HDs set up as a redundant RAID disk with 500GB available storage. It was becoming full, so I checked the hard disk compatibility list and orde...
This painful saga rolls on…
Both Seagate 2TB ST2000DM001 drives failed after or during initial sync. They’re going straight back to Amazon, and I've ordered a pair of Western Digital Red HDs. For reference for anyone searching this forum in the future for compatibility experience, both Seagate drives were manufactured in China, not Thailand. Firmware on both was CC26. Based on my experience, I wouldn't go near that model for use in a Duo v1 if I were you.
And now we get to the thorny bit…
I hot-swapped the 2nd "dead' Seagate out of SATA channel 1 this morning and replaced it with the old 500GB drive from that channel. The smaller HD initialized and then the Share disconnected. RAIDar could not locate the Duo, although the Duo's power light was steady, and the green LED was flashing for the new HD and steady for channel 2 in which has remained the second of the 2 original 500GB drives all along. After half an hour of refreshing RAIDar to no avail, I pulled the power to the Duo.
On reboot, Frontview reports the 500GB drive as "UNKNOWN [1862 GB]". Clearly something is amiss here.
So, I shut the Duo down from Frontview. Then I removed the mis-reported HD from slot 1 and powered the Duo back up with no disk or caddy in slot 1 at all. And still Frontview tells me that there are 2 disks in the Duo, and that the one in slot 1 is "UNKNOWN [1862 GB]".
I've made another USB backup in case everything goes south before the WD Reds arrive, but does anyone have a suggestion for how to persuade the Duo that it does indeed only have 1 disk in it, as I'm concerned that this might mess up installation of the Reds when the time comes.
(Experienced users, if you think this merits a new topic I will happily make one, of course.)
