Hello, i am posting this question just to be sure.
i have Seagate 440/420 raid10 and one of the 4 drives is off.
i read that i just have to put a similar empty drive (seagate 1Tb) (formatted?)
and the 2nd drive will start copy files (mirror) to the new drive.

are these info correct or i have to beware of anything?
thank you

I guess the one who might Answer you here is Dr.Kiev (PM)

good luck


btw, i have 2 of those NAS - good choice

In such case your NAS should be working still. If not , the problem can be elsewhere , and that step you gonna do can be dangerouse.
For example, some drive wasn't working period of time in the past , but NAS was working fine , now you have another "offlined" drive, and if you start HW rebuilding process you can lose all fresh data.
I would suggest you to recreate virtual array ( without any writes) or clone all drives before rebuilding, or ask for professional help .

thanks for the tip.
The drive works perfectly with 3 drives.
i only want to be sure that pluging a new drive won't cause any further problems

Will NOT - don`t worry - i tried it many times here

always update the NAS FW - for performance issues

good luck

Forgot to mention, adding new hdd to the NAS will take some time preparing it depends on size
mine adding new 3TB took like 15min. and after that was visible in GUI

you can monitor the status in LED

At the NAS there the 2,3,4 drives working fine and are plugged in. as you can see at the screenshot there is a failure at the volume. i see the files on the nework. i am trying to access without any success. i changed the pass on the admin but still nothing.

Now, i See Diff. Tone here based on the facts you told from the beginning
you are changing subjects

get back to Dr.Kiev if you wanted your data back.

good luck
