format hard drive no longer used in readynas raid 1
Hello everyone - I did some digging around and couldn't find anything specific on this.
I have a ReadyNas 102 on RAID 1 with 2 x 2TB. I originally had 2 x 1TB on RAID 1. I'm looking to repurpose the 1TB hard drives and wanted to format them.
(Who knew you couldn't connect them to your windows laptop to format? not this guy)
Wondering how I might go about formatting them. Do I remove one of the 2TB hard drives, insert one of the 1TB hard drives and use the web interface to format it? Is there a better or easier way?
I'm concerned that if I swap a 2TB with a 1TB then the NAS is just going to try to start mirroring to sync everything on RAID 1.
Thank you!

I used an external sata connector to connect the 1TB hard drive to my laptop and in Disk Management, its not initialized. When I try to initialize it, I get an error that states: data error cyclic redundancy check.
Which means something has failed - likely either drive has failed or the USB SATA adapter. Though also check that the cabling is secure (both data and power).
You might try testing the drive with vendor tools (Seatools for Seagate, Dashboard for Western Digital).
FWIW, I suggest zeroing the drive before resale instead of reformatting. Seatools has an test that will do that (though it might not be enabled with non-Seagate drives). There are other free tools that do this as well, including the AOMEI partition manager.

You are confusing reading the files on the drive with formating. Windows doesn't recognize the file system, so it won't mount it. But it's still just a SATA drive, so you can initialize, format, etc.
