Thats good, now we know that bad block is part of the unallocated space. More specifically somewhere in the first 70GB (in round numbers).
The next task is see if that bad block or blocks can be isolated or eliminated. This is going to be a multistep process.
- Open 'Disk Management' and right click on the 'Unallocated' space.
- Select 'New Simple Volume'.
3) When the 'New Simple Volume Wizard' windows is displayed click on the 'Next' button.
- There are three values displayed (Max, Min and Simple Volume size), the default value is to use all the unallocated space so leave the value unchanged and click 'Next'.
- You should see the drive letter that will be assigned, no need to change it, so click 'Next'.
- The Format Partition options should be set to the following: File System 'NTFS', Allocation unit size 'Default'. Volume Label 'New Volume' change the volume label to "Test Volume" (without the quotes). Uncheck 'Perform a quick format' (no check mark), Enable
file and folder compression: leave this unchecked.
Click the 'Next' button.
- Completing the New Simple Volume Wizard will show the options you selected, the most important should read 'Ouick Format: No. Click the 'Finish' button.
This will start a "Full" format of the what was once unallocatede space and when complete (this will take a fairly long time to complete).
For reference purposes if you install Windows 7 on a new hard drive it performs a 'Quick Format' which does not pick up/identify and fix bad blocks.
The 'Full Format' you are now performing hopefully will pick up these bad blocks/sectors and mark them so they are no longer used.
Now when the format completes close out the 'Auto Play' window.
You should now see your new logical drive ("Test Volume") and the size. Make a note of the drive letter that was assigned. (Example: E:)
Close 'Disk Management', run check disk on the new (Test Volume) partition E: and report back if check disk passes or fails and what the % number is?
Good Luck:
