I'm not sure where you read that booting with a missing drive is a bad idea, but that's exactly what I suggest if you know which drive is creating the problem unless you are running RAID0. The volume may come up, though degraded (not redundant), but should allow you to access it and download everything over the LAN connection (which is far faster on a NV+ than the USB ports) if it does. Of course, that drive could just be the long pole and another problem comes up once it's gone. But I don't believe any damage will be done to your volume if you try.

Just don't put the drive back in with power applied if it does come up, as the NAS will attempt to re-sync it and you already have suspicion it's got problems.

In addition to booting w/o one drive, I'd also suggest telling the NAS to skip the file system check via the boot menu. See pages 23-24 here: https://www.downloads.netgear.com/files/GDC/RND2110/Duov1_NV+v1_HW_en_06Dec11.pdf
