No, I don't think so.

No matter how you partitioned the drive, the kernel should still, at
least, report the plugged in USB device.

Depending on what those "file system creation errors" exactly were, they
may already have been symptoms of a drive going faulty.

The first thing I'd do is change the USB cable. If that doesn't improve
things, I'd try to connect the drive to another machine. If it's not
working there either, I'd contact the vendor for replacement.
