Okay so this is annoying my EX2 Ultra has decidded to mark Drive 2 as BAD,
These are 4TB WD RED Disks
I have plugged the drive into and external enclosure and Crystal Disk Info indicates the drive is in Good Health, as do a couple of other tools.
I have erased cleared the partition table and erased the disk and once reinserted in the EX2 it became marked as bad again.
I have tested the disk in another NAS by a different Vendor again no issues and the NAS reports the disk is fine.
I have also tried the Disk in Bay1 of the EX2 Ultra and again it go marked as bad, none of the parameters for smart are even close to exceeding the thresholds.
Clearly this device has a very agressive idea of what failure means! (no doubt to force the consumer to by disks they do not really need to buy)
The make you throw it away culture.
Anyone else seen this and know of a way to deal with it without replacing what is clearly not a failed disk
It did this before which was when I replaced the disks with the 4TB RED Disks, I was not convinced this time so instead of throwing them out I started looking and conclusioin the disk is fine the NAS is a steaming pile of ! I was considering getting an ex4 i might reconsider now
Does the PR4100 do the same annoying ■■■■ where it wipes out any custom stuff you did over SSH on a reboot like the ex2 does ? I did wonder if there was anyway to get a plain linux os onto the EX2?
The problem I have is the instructions I have just found won’t work as they tell you to install firmware via normal dashboard but I upgrade to OS5 so that does not work with the firmware I found
Oh hang on I think ive got this if I wipe out the mtdblock device this should boot into safe mode and load whatever firmware I shove at it lets try that
I’ve had a similar issue with a disk marked as bad. Ran a full diagnostic which I came back to later on, found that the firm wear (5.08.115) had been downloaded and installed to the drive, and then finding that both disks are both now marked as good, so not 100% sure if this is a failure, a predicted failure or simply the older firm wear thinking it was broken?
That would be something, DSM seems highly functional and has ‘actual’ apps for most use cases I have. It would be awesome to have DSM on my PR4100 as it has decent hardware and build quality but really ■■■■■■ software.
Somebody tried it earlier, no sure if it would be useful. DSM is indeed light years ahead of OS3/5 wrt app availability. Also, DSM7 vs OS5 rollout is a good sign of their customer focus.
When about the same happened on Ex2 with a WD red pro 4 TB
I just replaced and used the old disks for other use
One marked bad disk did not pass the Western Digital Data LifeGuard Diagnostic for Windows long term sector by sector test but the other did pass.
Using both still for light duty non critical storage
I too use Debian raid on a old Mac mini to read WD nas drives BUT I also have a WD mybook on all my WD NAS units as a back up and that is easy to read the files.
lets not brick a device
