If you do not declare a PATH variable in your script or crontab then the PATH will be
hdiutil manipulates disk images. It will unmount attached file systems but you should be using diskutil to unmount them. diskutil may not need the device node to unmount a file system. I think you can use the mount point. If you want to use the device node then the following should work
You should not need to unmount and mount a file system in order to make your backup strategy work. It might be time to rethink what you are doing.
This isn't the usual problem that a shell script runs from the command line and not the cron. It's a little different.
Among other things, the shell scrip executes my .profile to set a bunch of variables. It then does an env to ensure that it ran OK.

exfat.util
EXFAT.UTIL(8) BSD System Manager's Manual EXFAT.UTIL(8)NAME
exfat.util -- ExFAT file system utility
SYNOPSIS
exfat.util -p device removable writable
exfat.util -k device
exfat.util -s device
exfat.util -m device directory removable writable nosuid nodev
exfat.util -u device
DESCRIPTION
The exfat.util command supports the probing of ExFAT file systems, and getting or setting a volume UUID.
Options:
-p device removable writable
Probe the device to determine whether it contains an ExFAT file system. The removable and writable arguments are ignored for compat-
ibility with other file system utilities. If the device appears to contain an ExFAT file system, the exit status is 255. If the
file system contains a label (volume name), that name is written to standard output. If the device does not appear to contain an
ExFAT file system, the exit status is 254. An exit status of 252 indicates that an I/O error occurred.
-k device
Return the volume UUID of the ExFAT file system on device. If the device appears to contain an ExFAT file system, the volume's UUID
is written to standard output (as formatted by uuid_unparse(3)), and the exit status is 253. If the root directory contains a Volume
GUID entry, that GUID is the value returned; otherwise, the 32-bit volume serial number stored in the boot sector is converted to a
UUID and returned. If the device does not appear to contain an ExFAT file system, the exit status is 254. An exit status of 252
indicates that an I/O error occurred.
device may be mounted or unmounted. If it is mounted, the UUID is obtained through the file system using the getattrlist(2) call.
If the device is not mounted, exfat.util reads from the device directly.
-s device
Set a new UUID for the ExFAT file system on device, which must not be mounted. This generates a new UUID using uuid_generate(3) and
stores that UUID in a Volume GUID entry in the root directory (creating one if one does not exist, or updating an existing entry).
If the UUID is successfully set, the exit status is 253. If the device does not appear to contain an ExFAT file system, the exit
status is 254. An exit status of 252 indicates that device was already mounted, or an I/O error occurred.
-m device directory removable writable nosuid nodev
Deprecated. Mount the ExFAT file system from device onto directory. The removable argument should be either removable if the device
is removable, or fixed otherwise. The actual argument value is currently ignored. The writable argument must be either readonly or
writable which mounts the volume read-only or read/write, respectively. The nosuid argument must be either suid or nosuid. That
argument is passed as a mount option. The nodev argument must be either dev or nodev. That argument is passed as a mount option.
-u device
Deprecated. Unmount the file system on device. If the unmount is successful, the exit status is 253.
FILES
The exfat.util command is installed in the /System/Library/Filesystems/exfat.fs/Contents/Resources directory, which is typically not in a
shell's search path.
COMPATIBILITY
The -m and -u options are deprecated. The preferred way to mount an ExFAT volume is to let diskarbitrationd(8) mount it automatically when
the device is discovered, or use the diskutil(8) command to explicitly mount a device. You may also use the mount(8) or mount_exfat(8) com-
mands directly. The preferred way to unmount an ExFAT volume is with the diskutil(8) command. Note that using the umount(8) command usually
will not work because various process are likely to have open files, which will prevent the unmount. The diskutil(8) command will send a
notification that causes many such processes to close their open files so that the unmount will succeed.

The exfat.util utility first appeared in Mac OS X 10.6.3.
BUGS
The choice of non-zero exit status to indicate success was an unfortunate design decision.
The -u option usually does not work since several processes in Mac OS X leave files open on mounted volumes, thus preventing the unmount.
The diskutil(8) command is preferred for unmounting.
