Replace all discs on ReadyNAS 314
Hi all Running a ReadyNAS 314 4 bay unit with firmware 6.6.1 running X-RAID. Drives have been reporting increasing sector reallocations, with one particularly bad, so I'm going to take the op...

Hi All
Just an update.
Purchased 4 new Seagate Enterprise ES.3 ST3000NM0033 3TB drives.
After taking a back-up of my NAS with the old drives, swapped in one drive at a time, starting by replacing the one with the ATA errors (only one had ATA errors) and also the highest number of reallocated sectors.
Swapped drive by drive and let the NAS rebuild. Was replacing 1.5TB drives, and although I had quite a bit of free space remaining even with those drives, I'm happy to have upped the amount of space available.
Each drive took about 12 hours to rebuild on to, so after two days had a fully rebuilt NAS, now running on brand new, error free drives, with 5 year warranties.
Relieved with it being complete with no data loss. Would have been an inconvenience more than anything if it had failed, but glad it didn't. Fortunate also that it didn't as the ATA errors on one drive were quite high. And on 3 of the 4 drives I had more than 4,000 reallocated sectors, with the 4th drive having only 10.
Lucky escape, and now well covered.
Thanks for advice on here.
Cheers
Andy

If you are making a backup anyway, you could start over with fewer/larger disks.
For instance, 3x4TB would give you an 8 TB volume, and give you an empty bay for expansion later. Building a completely new volume will be faster than rsyncing four times.
