You say you have "couple bad sectors on my SSD".
This is what the Crucial article
My SSD has bad sectors has to say :
My SSD has a lot of bad sectors. Do I need to replace it?
With a traditional hard drive, that is often the case, but with an SSD
things are a bit different. Due to the nature of flash technology it's
normal to have a small number of bad sectors on an SSD, and as long as
the number of bad sectors remains constant there is no reason for
The easiest way to keep track of the number of bad sectors on an SSD
is to run ChkDsk.
If the number of bad sectors remains the same, all is well.
I would keep an eye on this SSD, before a catastrophic error occurs,
and ensure having good backups at all times.
sfc /scannow was unable to complete, it seems that your Windows
installation has suffered some damage. I would therefore counsel :
- In registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches, see if you have an item named
These flags control the execution of cleanmgr.
If you do, export a copy of the key and delete this item(s).
Reboot to be sure it is effective.
If this does not help or the flag is absent, continue on in this list.
- Run chkdsk to flag all bad sectors
- Do a Repair Install of Windows.
This in-place upgrade install will fix your currently installed Windows 8 without losing anything.
Use a recent enough version of Windows 8 installation media.
- If Repair Install fails, you would need to reset or refresh Windows,
which would unfortunately mean losing data and installed applications.
Before taking the last two steps, just in case you end up by destroying your setup,
take an image backup and do not place it on the system drive.
Use for example AOMEI Backupper System Backup (and have it verify the backup).
Create first a Windows PE & Linux Bootable Disc. Try the boot disc/usb before starting, to verify
that it can detect both the system disk and the backup file.
