To copy data from bad sector disk, you can use the cloning software AOMEI Backupper. It enables you to clone hard drive with bad sectors, or copy files without booting Windows.
Bad sectors are areas on the hard disk that have become damaged and unable to reliably store data. Usually, users can get bad sectors report by running chkdsk to check hard drive error, and the causes are varied.
When bad sectors arise, it's crucial to proceed with caution to minimize further data loss or damage to the disk. You may want to replace the hard drive containing bad sectors, and copy the files or OS to the new one.
💬“I recently purchased a Samsung 840 EVO in order to replace my current Western Digital HDD in my laptop. I did this because my current hard drive was showing signs of failure, such as having bad sectors. However, because of these bad sectors I can't use Samsung's migration software to transfer both the OS and files from my old HDD to my new SSD. Is there any way that I can transfer both of these?”
This user‘s hard disk shows a sign of bad sectors, and he tries to transfer everything to new SSD in an attempt of replacing disk without losing data. This is possible, first of all. Let's talk about it in detail.
If there are only soft bad sectors (logical defects) instead of hard bad sectors (physical defects), then you can copy data from a bad sector disk. Even with some relatively serious system failures, by using a bootable media, you can still copy files without booting Windows.
For users who want to keep everything including old files and operating system (just as in the above case) intact, it may be easier to clone a hard drive with bad sectors. However, the cloning may terminate as it fails to read the data.
Simply put, if you want to copy a bad sector disk to another disk without reinstalling, you need to use a migration tool that can skip bad sectors during cloning.
From a data security perspective, once you have bad sectors on a disk, you should take measures immediately. Either find a way to remove bad sectors or copy data from bad sector hard disk.
Your hard disk can be partially repaired by the Windows CHKDSK utility. Before running CHKDSK, you'd better restore everything that could be recovered beforehand. Then you can repair your hard drive in following steps:
Step 1. Open computer and find the disk (here is E:\).
Step 2. Right-click on the Start button. Then select Command prompt and run as Administrator from the menu.
Step 3. Type command "chkdsk /f /r /x E:" in the command prompt.
Step 4. Click Enter to start repair process.
It is recommended that you copy your data from bad sector hard disk to another drive after repairing.
CHKDSK does not always bring your HDD or SSD back to a healthy state. To ensure the data security, it's essential to copy important data or clone everything from a bad sector hard disk.
The annoyed thing is that many software cannot clone a failing hard drive. Therefore, I'd like to offer a reliable cloning software that supports cloning HDD/SSD even with bad sectors.
AOMEI Backupper Professional is the best cloning software for Windows 11/10/8.1/8/7/Vista/XP. It runs in an intelligent mode by defalt to copy only used sectors, skipping unused and logically bad sectors.
▪ This means you can clone larger HDD to smaller SSD, or clone a bad sector disk without accidental termination. By the way, with volume shadow copy service (VSS) technology, the cloning process won’t interrupt your work. ▪ It also allows you to create a bootable USB (or a built-in recovery partition) that can boot your problematic computer into WinPE, and copy files from hard drive with bad sectors.

How to copy fata from bad sector HDD or SSD to another safe location? All you need to do are a few clicks. You can refer to the following steps.
If your computer has already failed to boot, you can use AOMEI Backupper to create a bootable media on a well-functioning and Windows-based computer at first. Then use the media to boot your PC (change boot order in BIOS or UEFI settings), and perform the following operation in WinRE.
Step 1. Launch AOMEI Backupper. Select Clone from the left side. Then click Disk Clone.
Step 2. Select the bad sector disk (Disk 0) that you want to clone. Then click Next.
Step 3. Select your Destination Disk (Disk 1). Then click Next.
Step 4. You can have a confirmation in this Operation Summary interface. Then you can click Start Clone to clone hard disk with bad sectors.
👉 Sector by sector clone is an optional cloning mode that will copy all the sectors including unused or logically bad sectors. Please do not tick this option, otherwise the bad setors will be copied over to the target disk.
👉 You can click Edit partitions in Step 4, it helps you clone hard drive and resize it with 3 options in the following. Also, you can convert the partition style with it.
👉 If you are cloning HDD to SSD in Windows 10, you can click SSD Alignment feature to accelerate the reading and writing speed of the SSD.
Step 1. Launch AOMEI Backupper. If you use a bootable media to start the computer, AOMEI Backupper should pop up in WinRE automatically. Click “Backup” and then click “File Backup”.
Step 2. Click “Add Folder” or "Add File" to select the folders/files you want to copy from the bad-sector disk.
Step 3. Select a destination path to which you want to copy files. It could be external storage (need to connect it in advance), NAS, or network share.
Step 4. Finally, click “Start Backup” to execute this task. Wait for it completes, close the program, and shut down the computer.
How to copy data from bad sector hard disk? AOMEI Backupper can help you solve this problem with its simple steps and intuitive interface. Besides, this software provides many practical features like disk restore, partition clone, partition backup, etc. You can use them by your needs.
