Our tech doesn't think it's a hardware failure and is planning to reinstall windows. I ran chkdsk and it didn't find anything, but I keep seeing other oddities. Examples below:

DSIM Error

C:\Windows\system32>dism /online /cleanup-image /scanhealth

Deployment Image Servicing and Management tool
Version: 6.3.9600.17031

Image Version: 6.3.9600.17031


Error: 1117

The request could not be performed because of an I/O device error.

The DISM log file can be found at C:\Windows\Logs\DISM\dism.log

SFC Error

Beginning system scan.  This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection found integrity violations. Details are included
in the CBS.Log windir\Logs\CBS\CBS.log. For example
C:\Windows\Logs\CBS\CBS.log. Note that logging is currently not supported in
offline servicing scenarios.

Bitlocker Error

Again, a full CHKDSK on boot showed no errors. I haven't been a tech for a long time, but everything else makes it look like a hardware issue. How can I better determine if it is a hardware issue?

  • That led me to hdtune.com which I ran and it did show bad blocks. Thanks! Would you post an answer recommending that utility (or another) and I will accept it? Mar 17 '16 at 15:41
  • Check before the SMART response, and after yes, it's probable that your "tech" is right. You will go to install again from scratch windows... on a new Hard Disk! :-). Seriously check the SMART response.

    @DevilsAdvocate Pick one of the lucky others to get the points ;)

    I think @Xavierjazz is a little confused. ;) People can suggest products in answers (as long as they explain how to use them to solve the problem at hand). We just can't ask questions like "Can you recommend a product that does XYZ?" :) Mar 17 '16 at 16:05

Before reinstalling windows or any other OS, in cases like yours you should check the response of .

S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology; often written as SMART) is a monitoring system included in computer hard disk drives (HDDs) and solid-state drives (SSDs) that detects and reports on various indicators of drive reliability, with the intent of enabling the anticipation of hardware failures. [wikipedia]

If you want to remain generic in your learning, smartmontools is available for Windows, Linux, Mac, etc. Or, if you prefer a more cozy GUI, you can go with hdtune or any of the solutions proposed in the questions below.

For a comparison of S.M.A.R.T. tools you can start from the wikipedia page about it

  • Status: The SSD has damaged blocks. Thanks! Mar 17 '16 at 15:54
  • Maybe you can still mark all them and save the disk... or maybe not, but you can see.

  • Back in the day a bad sector often meant an impending head crash. What causes a "Damaged Block" on a drive with no moving parts? Is it more at risk? Mar 17 '16 at 16:04

    @DevilsAdvocate "да нет наверное" Seldom foreign languages can provide appropriate expression absent in your own: "yes,no, of course". For different reasons but, maybe, with the same ending. It should depend from the model, the amount of errors, the rate of new failures... but if you have a growing number of bad blocks you can imagine the end by yourself with not so more need of additional info. Good Old times the ones when the HDD warned you with its clicks (you can listen some example from the link)

  • @Hastur It is an SSD: Marking bad blocks doesn't work on SSD's like it used to do on old-fashioned harddisks. Even modern classic harddisks (non-SSD) can no longer "mark" bad blocks. In stead the internal controller in the drive automatically replaces the bad blocks with good blocks from its spare capacity. By the time a bad block shows to the OS a modern disk is already beyond saving, because the controller doesn't have any spare blocks left: Backup your data and get rid of the failing disk asap.

Try downloading Acronis Drive Monitor which will give you an overview on the SMART results for your drive. This might show you an error somewhere
