Having an issue getting my data off or operating normally with my DX4000, 3TB model with two WD3000F9YZ drives in it. I tried to copy some data to it a few days ago and the copy failed. Naturally, I went over to the box and shut it down, came back in a few to turn it back on again. While booting, Drive 2 lit up Red and i got the “Drive Failure Imminent” on the LCD display. Turned the box off and ordered a replacement. No problem. Today I go to backup the data that is on it just in case the rebuild fails. Boot up the machine, drive 2 doesn’t light up at all. Not red, just off completely. Still get the “Drive failure imminent” message. Remote into it and go to copy to the external drive, takes probably 5 minutes to log in. Dashboard never loads, splash screen sits, then program stops responding. Resource monitor says CPU is at 10%, RAM at 80%, Disk highest usage time pegged at 100%, but little usage or drive IO is being used. I started the copy to the usb drive, and it began, never calculated remaining time, and peaked at like 600KB/s. I shut the machine down for fear of losing data. Before shutting down i did notice that the LCD panel hung on verifying at 56% and change.
Why would the one drive not appear at all (no red light)? Shouldn’t the NAS still operate at a reasonable speed with a degraded array? Isn’t that the whole point of the RAID 1 array? Shouldn’t the NAS have warned me about the failing drive before the reboot?
At this point I’m just looking for advice, I have pictures on there that I really wish keep. Should i try reseating drive 2? I’ve heard people swapping drive positions with real servers in case one slot in the controller fails.
I appreciate any or all input.
