Disk restoration from image after formatting
Programs of formatting a hard disk checks its surface and excludes the
damaged (unreliable) places from further use - this is written in the manual. Clearly, that if after formatting a hard disk something will be written on it, these excluded places will not be used. And will it be fair in the event when contents of this disk will be restored from an image which has been done BEFORE formatting (for example, by Acronis)? Thank you Lev |

All the bad sectors should be marked as unusable so when the image is restored to the drive the bad sectors will not be used. If your drive is showing a lot of bad sectors it could be a sign of impending drive failure and you may be better off to replace the drive with a new one. Later...... LabRat...... |:^{) |

Disk restoration from image after formatting
It depends. An 'image' backup and restore may be exactly that - an exact
image of the disk. In that case, the bad sector mapping will be as at the time of the backup, and any changes resulting from the Format procedure will be ignored. This form of backup/restore ignores the existing file system on the disk (including bad sectors) and simply puts everything back to exactly how it was. Other forms of backup/restore (including some that are described as 'image') will make use of the file system and will pay attention to the current bad sector mapping. You need to examine the documentation for the program or option to determine what forms of backup and restore operate at the file system level (and therefore respect bad sectors found by Format) and which operate at the disk level (and ignore the file system). -- Jeff Richards MS MVP (Windows - Shell/User) "Levlg" wrote in message ...
