Use Win. Disk Defragmenter.
Disk Defragmenter has been name changed in  Windows 8. to "Optimize Drives"

"What Happened to Disk Defragmenter in Windows 8?"

FYI for better assistance:

Our version of Windows is:  "8.1 Pro" from Control Panel >> System and "Microsoft Windows [Version 6.3.9600]" from the VER command via CMD DOS prompt.

The built-in Windows 8.1 defrag tool works fine.

I use Perfect Disk V13 by Raxco. This works great as well and is expensive.

Do not use ANY defrag tool on SSD drives.

Forgot to mention 3 things:

Our drive is HDD.
The 3rd part defrags mention so far, are there any issue or consideration to how they affect a Windows 8 Drive?
We noticed that there is a sector that is bad in the drive but the windows defrag doesn't isolate it.  That said, do these 3rd party defrag apps can isolate any bad sectors?
JohnBusiness Consultant (Owner)Commented:
No. I do not know of any defrag tool that isolates bad sectors.

From what I have read, you can try a full format (means backing up and reinstalling Windows) because I think Format will isolate bad sectors.

You might also consider replacing the hard drive.
Use Win. Disk Defragmenter but not on SSD drives.
"modern OS Windows don’t defragment solid state drives"

HDD Regenerator... $99.99

Ok thanx.

One last question before closing it, why you guys use a 3rd party apps recommended over Windows own Defrag?
JohnBusiness Consultant (Owner)Commented:
Perfect Disk uses real time optimization and does not need any attention or scheduling. I have been using it for a long time and I like this feature. Winfows Defrag is very decent and if it does what you want, use it
HDD repair is possible but back-up then replacement  of the HDD is recommended.
HDD Regenerator has helped me recover many failing HDDs to enable back-up and then replace the failing HDD.

Hope this helps.

Modern hard drives have disk errors at the disk level. When the drive is low level formatted. The formatter that writes the timing information to the drive maps out these errors and uses spare sectors.  The user does a high-level format and will not see these error sectors.  You don't have access to the low-level formatting utility since the disk controller is integrated with the physical drive and all you have is the i/o channel.  Modern drives use a very sophisticated error detection and correction routines since  with the density we write data to the drives a minuscule (on the order of microns) weak area if the drive has problems reading that section it will use its spare sectors and map out the errors automatically only when it gets a successful read, and it returns to the i/o channel the data after the error correction has taken place.  When one writes data to the drive if an error that cannot be corrected is detected then the sector is remapped and the data is confirmed written to the drive before the write buffer is cleared.   Your drive allocation map will not show these errors.  The relocated sector count is reported in the S.M.A.R.T. interface though.  All of this is done transparently to the host system and done internally on the drive itself.

HDD Regenerator/Spinrite attempt to turn off the drives internal error correction and do a RAW read and any weak sectors are passed onto the drive so it is aware of the problem and remaps the sector. These programs also will check the drive remap table and check these sectors and if they test fine return them to service.

The bottom line is that if you are getting crc errors at the operating system level, you know that you have already lost some data.. If the drive isn't reliably storing the data we put on it then the only recourse you have is to try a full format of the drive vice a quick format but it will in all likelihood fail. One should replace the drive and hopefully you are within the drives warranty period.
Personal opinion is that Spinrite/HDD Regenerator are avenues of last resort to attempt to recover data that is not otherwise backed up and easily replaceable. These programs take a LONG time.. sometimes on the order of days to process even a 500GB drive.  They are successful more times than not. The only step above them is a commercial recovery service which is good if it is a drive electronics failure or other physical problem. None of the above will offer a 100% guarantee of recovering 100% of your data.. They may recover enough of it to make the data usable though.. You might not notice a small artefact in a picture file.

Registry cleaners are not very effective in improving a pc's performance and the risk of damage is high.

your entry ID: 40853985 gave us an idea; some years back, on a HP PC, we used a tool for a the hard drive problems.  It fixed or allocated the bad sectors (not sure which since really was long time ago).   So maybe the hard this of this Toshiba PC we can do the same thing?  What do you think? (the drive is a Toshiba MQ01ABD100)


This question was placed because we have noticed that the PC would stay stuck in certain areas, but it happens few times.  The thing is that in an antivirus run we noticed that it stood at around 80% or so; we left running over 24 hours and stood the same.  So we thought a tool like defrag that can detect & isolate possible bad sectors.

Note, we have the windows 8 defrag ran automatically on a weekly basis; yet we don't get any messages (just finished Analyzing and came back on the screen with "Ok (0% fragmented)".


we have windows defrag ran automatically weekly.  Unfortunately, RegClean is for registry, not hard disk.  We have CCleaner and uses the option Registry option to clean up the registry maybe 1 or 2 a year (this PC its not used to constantly install / uninstall apps).

Based on David entry, is there an apps ot tool for Toshiba drives?
David Johnson, CD, MVPOwnerCommented:
are you thinking of the following?
from the command prompt

Probably not.. you probably don't even know about this command.. unless you've been in the industry from almost the start.
>>  we have noticed that the PC would stay stuck in certain areas, but it happens few times.  The thing is that in an antivirus run we noticed that it stood at around 80% or so;   <<  the i would start thinking about bad sections on the disk drive

run a diag on it, i mostly use UBCD for this - which holds all diags you need :
Hardware diagnostic CD    UBCD

go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP :

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)                        ultimate boot cd             download page

**  you can make a bootable cd - or bootable usb stick

for completeness -here's how i handle disk problems :

Sorry for the delay, been super sick but back to work!

So we will proceed to close the question and award accordingly,

Thanx for your patience.
sorry- after rereading, i see i offered wrong advce above - it's ok for testing ram, but not for SSD
you need to use the manufavcturer tool, like the intel toolkit :
