I've recently purchased a Dell Vostro 470 and added a Samsung 830 256GB SSD. I;ve done a clean install of Windows 8 onto the SSD. So now I have two disks, the SSD as C: and the 500GB disk as D:.

The Action Centre keeps popping up telling me to "Restart now to repair disks". When I click restart, it just boots back to Windows. I see no signs of any repair happening, then when I'm back in Windows, the notification will pop up again in the Action Centre.

How can I tell which disk Windows is concerned with and how can I help Windows to actually perform the repair?

Scan disks or run chkdsk on your disks.

  1. Using Windows GUI:
    1. In File Explorer right-click a disk.
    2. Click Tools tab.
    3. Click Check now button in Error-checking group (the first group on the tab).
  2. Using command-line utility:
    1. Open Command Prompt with Administrative privileges.
    2. Type chkdsk /f D: and press Enter to check disk D: for errors.
      In place of D: use other disk letters to check them.
    3. To check disk C: run:
      chkdsk /f C:

Checking system disk, C:, requires a reboot.

If you want to check for bad sectors on the disk, either add /r option to chkdsk command, or select Scan for and attempt recovery of bad sectors if using GUI.

Try checking for bad sectors on your disks. There are many utilities out there that can scan for bad sectors.

I use this:

If there are bad sectors on a disk then it will fail eventually and your data with it. You should back up data from a disk that is failing to another hard drive.

Your 500GB disk seems suspect, I hope it's ok.

Good luck!

Why does the 500gb disk seem suspect? It's brand new... – Greg B Nov 12 '12 at 8:09
