  Nothing is loaded in safe mode that would cause the content of your
drive to change while you're running those apps.  When the contents
change, scandisk or defrag have to start over. There are ways to "kill"
these processes in normal mode (ctrl-alt-del, end task) but in my opinion
it's easier to just go into safe mode and not have to worry about it.

I believe you should track down what causes the restarts, if any, &
permanently disable it.

1. Turn off screen saver (R-Clk Desktop, Properties, Screen Saver--
None)
2. Turn off power management (Control Panel, Power Management-- Always
On,Never,Never,Never)
3. Disable any permanent internet cable connection, perhaps.
4. Suspend Task Scheduler
5. Turn off interfering programs. Use "StartupCop" or "EndItAll2" from
PCMag (below). Or "START, Run, MSConfig, Startup tab". Note what is
unchecked. Then, go to the General tab & disable the entire Startup
Group, by clicking "Selective.." & unchecking "Load Startup...". Reboot.
Don't forget to re-enable before the next boot.
6. Use "HDValet" from PCMag, or
(a) "Control Panel, Internet Options, Delete Files button, bolt Delete
all offline content, OK, OK"
(b) "START, Run, %TEMP%", & delete all files that will let you. This
will likely be "C:\Windows\Temp". This is best done after a fresh boot,
unless you have not seen the message "Reboot to complete this install".
7. Run Scandisk (Thorough, usually w/o write testing. Check all three
items under "Scandisk, Advanced button, 'Check files for' box". If you
want to be informed as it does a fix, UNcheck "Automatically fix errors"
on the front screen, or look inside "C:\Scandisk.log" afterwards.)
8. "START, Run, Defrag /p /details". Apparently, "/p" Defrags the
unmovables.

The purpose of steps 1-5 is only to prevent constant restarts of
Scandisk & Defrag, if you get them; but DEFINITELY turn off the Virus
Scanner. Scandisk should be done perhaps once a month, and certainly
after every serious crash. Do a Defrag after a sluggish boot or when
this says so:

Also, take DiskAction, to determine what is constantly writing to the
HDD, which causes the restarts. Take BHOCop & StartupCop too.

"DiskAction" reports the last 12 processes that access any partition. It
discovered the MS Critical Update Notification Tool was accessing my
HDD every five minutes. It can be uninstalled in "Control Panel,
Add/Remove Programs". Then, occasionally, "START, Windows Update" on
your own.

"BHOCop" found a Browser Helper Object called Wavehelper Class, created
by "Wavetop", that was building a monstrosity of an error log called
"Logit.txt" in here. "START, Find, F/F, Logit.txt"-- see one?

Now, my hard drive is quieter than my mouse. (Of course, I now also have
384 MB RAM, up from an initial 64, eliminating Swap File activity.)
