On a Windows forum, there is a question saying "Clonezilla failed due to bad sectors on laptop, will chkdsk repair?" Most of the answers are suggesting the questioner replace a new hard drive. What if you're in the same situation but still have a try on your old hard drive? In this article, we will focus on the same topic, telling you how to continue to clone a hard drive that has bad sectors.
Why Hard Drives Get Bad Sectors?
A hard disk is composed of several small storage space clusters. One cluster equals one or more sectors, and the number of clusters depends on the file system of the hard drive. So the cluster is the smallest allocation unit and the sector is the smallest addressable unit. When there are bad sectors on the hard drive, these sectors won't respond to read or write requests.
Generally, there are two kinds of bad sectors, one is the physical bad sector (hard bad sector), and the other is the logical bad sector (soft bad sector). The head of the hard disk drive is damaged, the dust has fallen on that sector, the flash memory unit of the solid-state drive is worn out, or other defects or wear problems may cause hard bad sectors to appear.
The reason why the soft bad sector appears is that the operating system may have tried to read data on the hard drive from this sector and found that the error-correcting code (ECC) didn't match the contents of the sector.
If your hard drive has hard bad sectors, unfortunately, this damage is irreparable. You'd better buy a new hard drive. However, if the bad sectors are soft ones, your hard drive can be repaired by overwriting the drive with zeros or performing a format.
This page explains why your cloned hard drive or SSD won't boot and offers practical fixes to help you make cloned drive bootable on Windows.
