Hi!

I used my DNS-320L with 2x1TB hard disks and raid 1. When one HD had a bad SMART check, I replaced it with a 3 TB HDD.

The DNS-Software told me that I could use 1 TB for Raid-1 and keep the rest for later.
Now I replaced the second 1 TB HDD with another 3 TB HDD, to get 3 TB at all.

Unfortunately the D-Link interface will only ask me to format the rest (2x2 TB) for JBOD.

So my question is: Is there any chance to expand my Raid 1 to the full 3 TB now, or will I have to re-format everything and copy things there from the start if I want to have full 3 TB with Raid 1?

The safest way is to make sure you have a full backup of your data then reformat the drives as a new RAID 1 array of 3TB then restore the data from the backup.

Doing it this way ensures that you have a clean RAID 1 array and your data is in consistent form.

Ok, I did this. Just put one of the old 1 TB hdd into my windows computer and installed the Paragon extfs driver and copied files from there to my nas. I cannot recommend the ext2fsd freeware driver, since it will have problems handling filenames with umlauts (like ö, ä, ü, etc.).

Sorry, I didn't realise you had accented characters in file names so didn't give a warning.  Here we have a computer that allows us to boot to several operating systems should the need arise to get data from other disk formats.
