Yes. DOS 3.3 does not have a plain "FORMAT" command; but, you can use
utilities such as Copy II+ to easily format a diskette without adding DOS or a
HELLO program.
A format will create 35 Tracks of 16 256-byte sectors each and verify that
each Track is good. Then, it will allocate the Catalog track and create a disk
info record called the "Volume Table of Contents" or "VTOC".

010- What is the "Volume Table of Contents" or "VTOC"?
The VTOC is a Sector which stores such basic information as Number of
Tracks, Sectors per Track, DOS version, ..., and the 'map' of used/un-used
Sectors. DOS 3.3 writes the VTOC at Track 17, Sector 0. (For more details on
VTOC content see Question 019.)

011- Can I assign names to my DOS 3.3 diskettes?
DOS 3.3 has no way to name a diskette "NARF", "DISK 100", "DATA DISK ",
etc. which DOS will recognize. You can, however, 'name' a diskette by giving it
a Volume Number in the range 1-255.
Volume Number is set at the time a diskette is initialized. For example ...
INIT HELLO, V19
INITs a diskette as Volume 19. If no number is specified, the default Volume
Number used by INIT is 254.
Several DOS commands can specify a Volume Number in order to decide whether
a diskette is the right one for some application.
LOAD NARF, D2, V5 ... for example, will not load NARF from Drive 2 unless the
diskette's Volume Number is 5.
A few early pieces of commercial software used Volume numbering; and, new
users often like to Volume number their diskettes. In practice, this turns out
to be a bad idea. A diskette with any Volume Number except the default (254) is
often difficult to work with via standard utilities. Also, once a diskette is
INITed for a certain Volume Number, changing the number is difficult because
Volume Number is embedded in each Sector. (i.e. You'll end up having to copy
every file to another diskette and, then,
re-INITing the source diskette to the new Volume Number.)
Besides, there's an easy way to give descriptive names to your DOS 3.3
diskettes which will not interfer with normal access. Just write the name
("GAMES DISK ONE", or whatever) to a Text file named, say, "DISK.ID".
DOS 3.3 will not know about the name or show it in a CATALOG. However, your
programs will be able to find out the name by just reading DISK.ID.
