Please help a noob erase 2 drivess and upgrade to larger drives

[Peter3Cats]

Hi all--

New here. Using a DS218+. Mostly for music storage. I am using 2 6tb drives in a SHR Raid array with 1 drive fault tolerance. I want to both upgrade to 14tb drives AND erase the existing drives for resale. I looked but could not find a step by step on this and certainly don't want to lose any data.

Thanks for any advice!!

Replace either drive with upgraded drive. Go into Storage Manager and Repair the Storage Pool. You will get a warning that all data on the new drive will be deleted; that's fine. This will take some time. When it's done, replace the other drive with upgraded drive. Go into Storage Manager and, again, Repair the Storage Pool.
Connect each of your 6TB drives to a PC using a USB enclosure and erase it using your data wipe software of choice. Here's a link to a variety of free choices if you don't already have one you like: 34 Free Programs to Completely Wipe Data From Hard Drives

If you are using a PC, you have diskpart <clean all> available.

I don't think diskpart's clean actually wipes the drive - it just deletes the partition information. If the object is to wipe the drive so that the data is unrecoverable, which is what I'd want to do before selling a drive, diskpart probably isn't sufficient.

You misread my post. I stated "clean all" which provides a forensic wipe.

Got it, yup, you're right...diskpart would certainly do it.

Glad you got your answers, I was going to suggest the same thing, replace 1 drive at a time, rebuild pool, replace 2nd drive, rebuild pool. Done. Then using diskpart on windows, connect your old drives and do sector wipe, which diskpart can do as I recall.

Glad you got good advice from the group and hope your process was as easy as it was supposed to be
