How do you recover data from raw disk partition on Mac or Linux?

由人工智能和领英社区提供技术支持

Have you ever encountered a situation where your disk partition becomes inaccessible or unreadable and shows up as raw? This can happen due to various reasons, such as file system corruption, virus infection, power failure, or improper operation. A raw disk partition means that the operating system cannot recognize the file system on it and cannot access the data stored on it. However, this does not mean that the data is lost forever. You can still recover data from raw disk partition on Mac or Linux by using some methods and tools. In this article, we will show you how to do that in four steps.

1 Check the disk status

The first step is to check the disk status and see if there is any physical damage or logical error on the disk. You can use the disk utility tool on Mac or the fdisk command on Linux to inspect the disk and its partitions. If the disk utility shows that the disk is not mounted or the partition is unformatted, or if the fdisk command shows that the partition type is unknown or has no valid signature, then you are dealing with a raw disk partition. You should also look for any bad sectors or SMART errors that indicate a failing disk.

On Mac or Linux, begin by checking the disk status with commands like DISKUTIL or FDISK -l. Before attempting recovery, create a backup of the raw disk partition to prevent data loss. Utilize tools like DD to create a disk image. For scanning and recovering data, tools such as TESTDISK or PHOTOREC prove effective, offering comprehensive file system and file type support. DDRESCUE is valuable for handling damaged media. Always operate on a duplicate to avoid further damage. These tools provide advanced options for deep scanning and recovering data from raw disk partitions on Mac or Linux systems.

To recover data from a raw disk partition on Mac or Linux, start by checking the disk's status for physical damage or logical errors. Use tools like Disk Utility on Mac or the fdisk command on Linux to inspect the disk and its partitions. If the disk isn't mounted or the partition is unformatted, or if fdisk shows an unknown partition type, it's likely a raw disk partition. Also, watch out for bad sectors or SMART errors indicating disk failure.

2 Backup the disk image

The second step is to backup the disk image before attempting any data recovery. This is to avoid any further damage or data loss caused by data recovery software or operations. You can use the dd command on Mac or Linux to create a disk image file of the raw disk partition. The dd command copies the raw data from one device to another, regardless of the file system or format. You will need enough free space on another disk or external drive to store the disk image file.

First, it's crucial to back up the raw disk partition to prevent further data loss. You can do this using the 'dd' command on Mac or Linux, which copies raw data from one device to another. Ensure you have enough space on another disk or external drive to store the disk image file. This step helps safeguard your data before attempting any recovery operations

3 Scan the disk image

The third step is to scan the disk image file with a data recovery software that can recognize and recover data from raw disk partitions. There are various data recovery software available for Mac or Linux, such as TestDisk, PhotoRec, R-Studio, or Stellar Data Recovery. You will need to choose the one that suits your needs and preferences. The data recovery software will scan the disk image file and try to find the lost files and folders based on their signatures or metadata. You will be able to preview and select the files you want to recover.

4 Recover the data

The final step is to recover the data from the disk image file to a safe location. You can use the data recovery software to save the recovered files and folders to another disk or external drive. You should not save the recovered data to the same disk or partition where the data loss occurred, as this may overwrite the existing data and make it unrecoverable. You should also verify the recovered data and check if they are intact and usable.
