Adding disk to volume on RN214
My RN214 currently has two 4TB disks inside, arranged as a single X-RAID volume (RAID 1). I've added a third 4TB disk and was expecting the volume to expand automatically onto the new disk. Apart fro...

Sandshark,
Which of the Seagate test suite is the full write test? It's not obvious...
I suggest running both tests (though obviously you can stop if the disk fails). Each will pick up problems that the other one misses.
But to answer your question, with Seatools you select the disk, and then look in the "Basic Tests" menu. At the bottom you'll see "advanced tests". Select that, and then choose "Full Erase (SATA)"

Hi,
I've just got myself to a location where I have a machine that I can connect the drive to by SATA and have checked SeaTools and I don't have that option. I've attached a screenshot of SeaTools, I'm guessing I want the Overwrite Erase test?
Thanks!

I'm not seeing your screenshot.
There is a guide here: https://www.seagate.com/files/www-content/support-content/downloads/seatools/_shared/downloads/pdf/SeaTools-for-windows-en-us.pdf
Page 5 shows the advanced test option.

Hi,
Apologies for forgetting to attach the screenshot... As you can see, the Advanced Tests menu I'm seeing offers different options to those described in the manual and I'm not quite sure which test equates to "Full Erase (SATA)". Is Overwrite Erase the appropriate one?
Thanks

Thx. You have a different version installed than I have (likely newer).
SCT Write will zero the disk faster - it uses a specialized command that only transfers one sector of data over the SATA interface that is then written multiple times to the disk (called write same in the ATA command set).
Overwrite Erase will zero the disk one sector at a time (exercising the SATA interface more heavily).
I'd go with Overwrite Erase. I am thinking that it won't run to completion anyway (given your symptoms).
There is a third option possible (for some drives), which is to do a cryptographic erase. If a drive supports hardware encryption, then simply changing the encryption key randomizes the disk contents. You wouldn't want to do that one, as it really doesn't exercise the drive at all. It's main benefit is that it instantly ensures the entire drive contents are made unreadable, even if there are bad sectors.
