Yes RMA means send it back
Personally i would give up on the drive with errors found on it and get it replaced
Its up to you otherwise you run the risk of it failing at a later date and having to go through it all anyway
The only thing i keep thinking about though is that i didnt think a HDD issue would affect memtest running as your booting from it, id hate to suggest you get new drive only to fit it and still have problems
Im gonna ask some others their opinion see what we can find out
