Do you really mean reformat or do you mean use the diskless recovery ?

Yeah, if they do mean a real format from the OS,
thats a pretty silly thing to do in the circumstances.

Nope.

True. An Everest SMART report would be handy given that it does mostly boot fine.

If the boot failures are just the system saying that there is no
hard drive to boot from it likely wont give you any useful info
on why thats happening, but if the boot failures are something
else, particularly if Win is saying it cant boot, it may well tell
you what the problem actually is.
Post just the SMART report here, it needs a bit of interpretation,
just ignore the OKs.

Sure, but doesnt that Toshiba have diagnostics available at boot time ?

OK, didnt realise it happened before you got into cloning.

OK.

Quite a few of the laptops play silly buggers on the visibility
of the drives, presumably thats what the problem is with DFT.
I dont use DFT anymore anyway, it isnt particularly
useful for the diagnosis of a hard drive problem like yours.
The SMART report is normally much more useful unless the
problem is that the laptop just cant see any drive at all at boot time.
In that case no diagnostic is any use either, it cant
diagnose any drive that isnt visible to the system.
The only real way to diagnose that sort of problem is by substitution,
see if the problem still happens with a different physical drive, in
which case the problem isnt the drive itself, its the drive subsystem
or the cable or even something as basic as the power supply etc.
You do sometimes see that particular symptom with a drive that
sometimes doesnt spin up. That will be visible in the SMART report.

Yeah, thats important to do in that situation.
Tho an image of the Win partition would be another approach,
tho you would have to wait till Toshiba replaces the drive to use
it. With a clone, you could use the clone until the replacement
drive shows up if Toshiba is happy to ship you a replacement
drive. They mostly prefer to have the whole laptop tho because
that allows them to change other stuff if replacing the drive
doesnt fix the problem. They may see a number of failures
like that with that particular laptop and know that it usually
isnt the drive thats the problem. It would be unusual for those
symptoms to be due to the drive, with the drive sometimes
failing to spin up if the system complains that it has no drive
to boot off.
The other real possibility if its actually Win complaining that
it cant boot is that some of the sectors are very marginal
and sometimes can be read and sometimes cant. If thats
the problem, the SMART report will show thats the problem.

I'll see if I can find something after posting this post.
Thats one of the reasons I dont normally buy Toshibas
myself, their maintenance manuals can be hard to find.
No use to you in the current situation tho given that its booting fine currently.
You would be able to try it if it the failure to boot shows up again, if
the failure is that the laptop says it hasnt got a hard drive to boot off.
If that happens, try booting the diskless recovery and just dont
actually do the recovery if it can boot the recovery partition.

The SMART report is that. It isnt useful in all circumstances, but usually is.
Main problem with any SMART report is that you do
need to know what you are doing to interpret them.
