Windows® frequently writes new data onto a system drive. Therefore data lost from a system drive can be overwritten any time while Windows® is active. The safest procedure to ensure maximum data recovery is as follows: shutdown the computer, remove the drive and
mount it on another Windows® computer where it becomes a data drive. Then follow the simpler and safer recovery procedure for a data drive. Make sure "CheckDisk" does not attempt to repair the drive at boot time.|
If you only have one computer, proceed as follows:
- Remove the source drive holding lost data to avoid making accidental changes to it in the next step.
- Install a new drive. Install Windows® XP or later. Install File Scavenger®.
- Reconnect the source drive as a data drive. Make sure "CheckDisk" does not attempt to repair the drive at boot time.
- Follow the recovery procedure for a data drive.
If these procedures are too difficult, use the 95% effective procedure for a system drive. The chance of a successful recovery is somewhat reduced. The reduction depends on the lost data, the level of activity on the computer and how closely the procedure is followed.
