is my C drive dying?

My PC had always been very sluggish compared to my old laptop.
When reading a PC magazine I read an article about Crystal diskinfo.
Decided to download the portable version ans ran it on the laptop: diagnose
OK.

Decided to run it also on the PC: WARNING for the C drive! (see below)
Is my C drive dying?
Apart from fitting a new drive this is going to be A LOT of work, installing
and updating Windows 7 and A LOT of applications!
I suppose I can't restore a Macrium image on the replacement drive?

The C: drive has 30 re-allocated sectors. I would replace ASAP, and
back-up now!

Reallocated sector count not zero = time to look for replacement.

That's telling you sectors on the hard disk have gone bad and drive is
mapping some reserved sectors into those areas. That makes it
transparent to the OS anything is going wrong but sooner or later there
will be no more sectors available to map into bad ones and then all hell
breaks loss The system is designed to have a pool of spares sectors
it uses for this purpose, obviously that's finite.

I've sometimes used such a drive as a backup drive for transient stuff.
Replace it, then use it as a second internal or put it in a USB
enclosure as an external. Then format it and start using it. If
reallocated sector count changes it's toast and just a matter of time.

Occassionally it could be a ont-time thing nut that's not likely.

Be aware that "Reallocated Sector Count" does not mean
data is corrupted. It means a sector was detected as
being less than functional, and was replaced by a
spare. Only a certain percentage of the total drive
capacity is available for sparing, so it will run
out eventually.

If you were to scan the drive and found no CRC errors,
you could easily make a backup of the drive as it stands.
Then restore the drive to a replacement hard drive. No
need to reinstall an OS or anything. Just use your
backup/restore program in Clone mode.

Take the following information, collected over three days.

Current Worst Threshold Data Status
Reallocated Sector Count 100 100 36 0 OK
Reallocated Sector Count 100 100 36 57 OK
Reallocated Sector Count 98 98 36 104 OK

On the third day, drive life is at 98%, and there are
104 reallocated sectors. That implies the spare sector
count remaining is roughly 5000 sectors (spread over the disk, not
all in one spot). I have used up 2% of them.

The reallocations tend to show up, if I write the drive
from end to end. I tend to see more of them after writing
the whole drive.

Note that the top line implies "perfect health". But the
whole thing is a sham. The reading is actually thresholded.
No drive leaves the factory in "perfect" condition. So
what you're looking at, is a portion of drive life.
The reason the statistic is not entirely accurate, is to
prevent buyers from "cherry picking" drives. If the
actual number of reallocations appeared in SMART,
people would keep returning drives until they got
one with a relatively low number of reallocations.
As a result, the drive appears defect-free for a long
period of time. Maybe after 100,000 sectors have been
spared, the last 5000 spares are recorded in the above
fashion. All I can tell you, is the observed behavior
does not match what is known about hard drives. That
field is "cooked". The field has diagnostic value,
but the scale is not "linear".

I've even had cases of "degraded" write speed on a
hard drive, only to see this in SMART. I.e. Perfect Health.
The Data field is the one with the defect count in it. SMART
is only really effective, if the reallocations are
spread smoothly over the disk, so no one tiny area
of the disk is slowed down. Reallocations make the disk
slower.
Current Worst Threshold Data Status
Reallocated Sector Count 100 100 36 0 OK

If I run out of spare sectors, and a sector is defective,
I could eventually see the sector throw a CRC error, because
the error pattern in it was too great for error correction
to fix.

Nothing prevents data from being corrupted, even when the
drive is new. The datasheet for the drive, lists the
corrected and uncorrected error rates to be expected.
However in practice, you'd be hard pressed to see the
background error rate, if it exists. Error correction
seems to do a good job (and costs some of the drive
capacity, to add that feature). Just as an SSD might have
25 bytes of ECC per 512 byte flash sector, for a total
of 537 bytes per sector of storage. If you cut the
drive capacity in half, you could allocate half of the
drive, just for the ECC bits. And give a very strong
data correction capability. For each generation of
drive (with new, flaky recording method), they figure
out the right number of ECC bits to add for that
generation. It's not necessarily a constant
percentage of overhead.

Download HDTune 2.55 and use the Health tab to verify
your findings. Take a picture of the screen with the
Health tab showing, and present the link here.

http://www.hdtune.com/files/hdtune_255.exe

(Example of an image hosting site, for your screenshot.
Use the snippingtool in Win7 for example, to take a picture.)

https://postimage.org/index.php?um=flash

In this picture, the drive shows 9 reallocations.
And since the health is still 100%, it's not in
real trouble yet. You would at least make sure you
have one recent full backup, stored on another disk.

http://atm.cyberec.com/~hello/pictures/Clipboard01.jpg

This is the boot drive on this computer, as recorded
some time ago. Both reallocated and current pending are 0.
On some brands of drives, current pending never goes
non-zero, until, perhaps, the drive has run out of
spare sectors. On other brands of drives, current
pending works properly. I mainly rely on the
reallocated field as a result. The brand in the
above picture, apparently has a working Pending field.

Note - SMART wasn't working properly on Windows 10
for a number of releases. It might be fixed now.
On the other Windows OSes, while the HDTune window
itself may show some weird behaviors, the data readout
is OK.

If you happen to own the Pro version of HDTune,
then you can use that instead.

*******

This should not be a lot of work to fix. Just clone
the broken drive to a new drive - all done.

But one of your drives is Maxtor brand, and since
I've had a few of those die overnight, I don't
particularly trust those further than I can
throw them :-( While some of my 500GB Seagates are
a bit smelly (show non-zero reallocation count),
they're not dead, which says a lot about them.
They don't seem to drop dead.

If the lubricant in the hub motor is gone, the
motor can seize instantly. I had one drive squeak
at startup, but it stopped a few days late.
No idea what that means. I have the word "squeak"
written on the top of the drive, so if it
dies some day, then I'll have some idea why.
We used to blame such noises, eons ago, on the
antistatic spring contact, but they don't use those
any more as far as I know.

Thanks for the crash course!
But VirusTotal gives 2 hits for this file... so I haven't installed it yet.

BTW could you explain (briefly) the difference between cloning and restoring
a drive?

Another thing: I also have 2 external USB hard drives. One tested OK, but
the other (Maxtor onetouch) isn't even detected by Crystal diskinfo. (it's
still working ok though)

Decided to download the portable version ans ran it on the laptop:

Decided to run it also on the PC: WARNING for the C drive! (see below)
Is my C drive dying?
Apart from fitting a new drive this is going to be A LOT of work,
installing and updating Windows 7 and A LOT of applications!
I suppose I can't restore a Macrium image on the replacement drive?


Be aware that "Reallocated Sector Count" does not mean
data is corrupted. It means a sector was detected as
being less than functional, and was replaced by a
spare. Only a certain percentage of the total drive
capacity is available for sparing, so it will run
out eventually.

If you were to scan the drive and found no CRC errors,
you could easily make a backup of the drive as it stands.
Then restore the drive to a replacement hard drive. No
need to reinstall an OS or anything. Just use your
backup/restore program in Clone mode.

Take the following information, collected over three days.

Current Worst Threshold Data Status
Reallocated Sector Count 100 100 36 0 OK
Reallocated Sector Count 100 100 36 57 OK
Reallocated Sector Count 98 98 36 104 OK

On the third day, drive life is at 98%, and there are
104 reallocated sectors. That implies the spare sector
count remaining is roughly 5000 sectors (spread over the disk, not
all in one spot). I have used up 2% of them.

The reallocations tend to show up, if I write the drive
from end to end. I tend to see more of them after writing
the whole drive.

Note that the top line implies "perfect health". But the
whole thing is a sham. The reading is actually thresholded.
No drive leaves the factory in "perfect" condition. So
what you're looking at, is a portion of drive life.
The reason the statistic is not entirely accurate, is to

Cloning a drive is taking a "snapshot" of the drive and duplicating it
on another drive. This snapshot info can aslo be stored in an "image"
file. Restoring is taking an "image file" created from a disk and
placing it on another (or same as one created) disk.

Think of that like a DVD is physcial and you can make a copy of it and
burn it on another dvd. You can also create an "image" of the dvd which
can be used to recreate a dvd, e..g. an iso file. Note - the image is
simply a file, it's contents store the information it needs to recreate
the dvd, kinda like a zip file in that aspect.

Thanks for the crash course!
But VirusTotal gives 2 hits for this file... so I haven't installed it yet.

BTW could you explain (briefly) the difference between cloning and
restoring a drive?

Another thing: I also have 2 external USB hard drives. One tested OK,
but the other (Maxtor onetouch) isn't even detected by Crystal diskinfo.
(it's still working ok though)

I compared the SHA256 on my 2009 copy of hdtune_255.exe with
a fresh download version, and they're the same. It's the same
value as listed on virustotal.

My guess would be, a false positive.

Here's a description of Trojan-Clicker.

I would not expect the second detection to be locatable in
Google.

I have HDTune 255 installed on just about every C:
drive I've got. I sure hope it isn't infected :-)

You would need an AV with known-good heuristic detection
capabilities, to catch it in time. Seeing as the major AV
products do not identify that as malware via its signature
alone. Windows Defender hasn't flagged it, but then,
WD isn't exactly bulletproof either.

"Clone" copies the content to a new disk. Windows assigns drive letters
as they arise. Once the drive on the right-hand-side is booted by
itself, it will become a C: drive.

+-----+----+-----------------+ Clone +-----+----+-----------------+
| MBR | C: | System Reserved | --- | MBR | D: | System Reserved |
+-----+----+-----------------+ +-----+----+-----------------+

Backup and restore, keeps a copy on an external disk for safe keeping.
The restoration can be made to the disk of your choosing, by booting
the Macrium CD and doing the restore from the external USB hard drive
to the internal drive. In other words, the destination disk can be
completely blank, and you can still restore to the destination disk.
No OS is needed, because the OS is on the Macrium CD. That's why
you always burn the emergency boot CD in Macrium, for this scenario
of restoration.

Both clone and backup/restore record...

1) MBR (partition table and boot code)
(partition table modified, if partitions are resized)
The boot code in the MBR is the thing that gets fixed if you "fixmbr".

2) Track 0 (i.e. the sectors next to the MBR, used by Linux)

3) Partitions, both hidden, foreign, and native/visible.
Truly foreign partitions are transferred sector by sector.
Recognized partitions, only the logical info is transferred,
and the "white space" on the partition is not copied. The
software knows which clusters contain actual live data.

The boot.ini or BCD files (for boot management), may be
edited for best customer flexibility. (No drive should go
"Offline" on you.) If you clone disks with "dd.exe" for example,
after you're finished, the destination drive could have an offline
status.

Modern clones are by no means, "absolutely identical". Far from it.
They are "logically" identical and have the same function. None
of your files get lost. There are no guarantees about any other
aspect. Most modern cloning or backup/restore software is not
good enough for usage in a Court Of Law. For that, you need
proper forensic tools.

4) PBR. The partition boot stuff is copied as a part of (3).
If the partition is resized, perhaps that requires modifying
the file system header, but the PBR would be preserved.
PBR is the thing that gets fixed if you "fixboot". Generally
the PBR is in the partition with the "Active" flag set. So
if System Reserved has the Active (boot) flag set, the PBR would
be there.

What I'm trying to say here, is they do surgical copying.
Also known as a "smart" copy. They only copy things that
absolutely need to be copied. Any white space not containing
your files, that part is not copied. If you have a 500GB partition
containing 20GB of files, then approximately 20GB of reads
and 20GB of writes will be involved. The other 480GB of
white space, will not be defined. This is why the backup or
clone takes ten minutes, and not two hours.

Backup/restore is not a good way to "wipe" a disk. If you
want a forensically clean destination drive, use DiskPart
and do a "clean all" to erase each sector on the destination
disk first. After the restore of the 20GB of files, the other
480GB will be in an all-zeros state, and no old stale files
can be recovered with Recuva or Photorec.

need special treatment, if you happen to be using such a thing.

Cloning: turning disc B into an exact copy of disc A. Involves two
drives, probably plus the drive (CD/DVD drive, USB stick, whatever) you
booted the cloning software from.

At its simplest, cloning software copies sector by sector from one drive
to another, regardless of whether they contain anything useful; though
most cloning software knows enough about how modern operating systems
(such as Windows) work, and only copies the sectors that contain
required data, unless you tell them otherwise.


Restoring: restoring a copy of a disc, from a backup you made earlier.
The backup could be a clone as above, but is more likely an _image_,
which is a _file_, containing details of the boot sector and one or more
partitions; an image file is not itself bootable. Restoring requires
(obviously) the drive you're restoring to, the drive the image is on
(which _could_ be e. g. a USB stick if big enough), and the drive you're
booting the restore software from.

Imaging software makes image files from the partitions (and even discs)
you tell it to; they're not unlike a giant ZIP file. Obviously, it knows
how to restore (unzip, if you like) these files later. Like cloning
software, modern imaging software knows enough about modern OSs to give
the option (usually the default) to only image the parts that had
relevant data on. They usually also offer compression, which makes the
image file even smaller, at the expense of some extra time while imaging
and restoring.

OK thanks. I have restored more than once (successfully), but never used the
"clone" option of Macrium yet.
