Problem with disk Seagate St300DM001
Hello,
I have 2 ReadyNAS; one old model NV and a more recent model 104.
It's strange but I have more problems with the 104.
I have added 2 new disks both 2 Seagate model ST3000DM001 and after few days it stopped to work saying that the disk #2 was dead.
I take out this disk and now I have attached to a laptop and works normally. So I don't know why the NAS say something wrong
Also the second disk start to give warnings logs (disk Detected high uncorrectable error count: [18528] on disk 3 (Internal) [ST3000DM001-9YN166, S1F01ZBY]. This condition often indicates an impending failure. Be prepared to replace this disk to maintain data redundancy.) and I can't see the data anymore.
Can someone explain me what's happening?
Many thanks

You say ou "added" these new drives. What was already in there?
Unfortunately, you made a poor choice of the new drives. "Green" drives such as the Seagate "DM" family are not well suited for a NAS. They notoriously do what happened to you -- go into power saving mode and the NAS declares them "dead". especially if mixed with non-green drives. That particular drive is not on the compatibility list, though the 2TB version is (a mistake, IMHO). While tools exist to change some behavior parameters on the WD green drives, I am not aware of a similar tool for Seagate.
Disabling disk spin-down on the NAS may help some.
The drive giving you the uncorrectable errors sounds like it may have a real problem, though I have had a different drive type give that kind of error and it was also not real. Have you checked the SMART errors? I hope you put that "dead" drive back in when you found it was actually OK. Otherwise, you are operating in a non-redundant mode and a second drive failure will kill the array (if you haven't lost it already since you cannot see the data).
Thank for the reply.
The disk #1 is a WD model WD10EFRX
The spin-down was already disabled
I checked the SMART but it say 0 error
The strange thing is that I don't see the temperature for this disk.
So you suggest to load the disk back on second trail?
And what about the disk on third trail? I have 142 GB data that look used but I can't see nothing.
Is there a way to restore these data?
So you don't have a backup?
