Very probably.
I often buy such product, but sold as second hand and with lower price
But in this case the vendor lied.
Actually, it reported neither new, used, refurb nor anything else about its age.
He did not caught his own fingers.

It looks like an attempted Windows installation or migration from hard disk to ssd.

Later it says that 81 LBA blocks were written, does not match if that usage is actual usage with no holes.

There are too many unknown attributes with SSDs :-(

can't be e2fsck.
# fsck.vfat /dev/sdb1 Logical sector size is zero. fsck.fat 4.1 (2017-01-24)
A look in a binary editor at sdb1 shows nothing but nulls.
Probably partitioned but not formatted.
Based upon smartctl it looks like the device may simply have been briefly tested, while the 21% in use on sdb3 suggests otherwise.
It may be a partially completed cloning process. The 81 LBA sectors actually written is a small figure, I wonder why. Depends on the LBA size. Is it 512 bytes, or is it perhaps 32 or 128 KB, which is the minimal write block on an SSD? I don't know. If you intend to keep and use that disk, do a full erase (not actually filling all with zeros, that's too much wear), and then partition and format yourself. Otherwise, just return it because the disk was used and he did not say so. Or ask for a lower price. Notice that new disks may have some hours of use for testing at factory, but may not be partitioned. -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)
