I have a 1 TB external hard drive which is often used for data backup. Yesterday, I accidentally ejected it from my computer without following proper procedure. After that, I was not able to access files on it, when I connected it back into my PC, it displayed "You need to format the disk in drive *: before you can use it. Do you want to format it?". I think my external hard drive is corrupted due to accidentally ejected. Can you tell me how to recover data from external hard drive? Thanks.
External hard drives are widely popular for their large capacity and portability. However, according to a data recovery company survey, external hard drives account for the largest share of data loss incidents. If you're facing this type of disaster, don't panic—finding a free data recovery solution becomes your top priority. That's where Hasleo Data Recovery comes in. This free software can recover data from formatted, corrupted, erased, dead, or undetected external hard drives with ease.
Download, install, and run Hasleo Data Recovery. On the main interface, select Deep Scan Recovery mode.
Select the external hard drive where you lost your files, then let the software scan it. The scanning process may take some time, depending on the drive's capacity.
Preview the recoverable files, then select the ones you need and click "Recover".
As a professional data recovery software, Hasleo Data Recovery can recover data from a formatted, erased, dead, broken, or not detected external hard drive.
Important Notes:
A: Yes, you can recover data from an external hard drive showing the format error. The error usually indicates file system corruption rather than actual data loss. Use Hasleo Data Recovery in Deep Scan Recovery mode to scan the drive and recover your files before formatting it.
A: External hard drives commonly become corrupted due to improper ejection without using 'Safely Remove Hardware', sudden power disconnection, file system corruption, virus attacks, physical shock or dropping, and age-related wear. These factors can damage the drive's file system structure.
A: This occurs when the file system metadata is corrupted while the actual data remains on the drive. Windows cannot read the file system, so it shows the drive as empty and prompts you to format. The data is not lost—it just needs professional recovery software to access it.
A: If the external hard drive is physically dead or broken (not detected by the computer), you may need professional data recovery services. However, if the drive is detected but shows as RAW or inaccessible, Hasleo Data Recovery can help recover data using deep scan technology.
A: To prevent external hard drive corruption, always use 'Safely Remove Hardware' before disconnecting, avoid dropping or physical shocks, keep your antivirus software updated, regularly back up important data, and avoid using the drive on multiple computers without proper ejection.
