Hello
Here are a few steps you can try to unlock it without damaging your data:
Check for Backup: If you have a backup of your data, you can restore it after formatting the drive. This is the safest way to ensure you don’t lose any data.
BitLocker Recovery Key: If you enabled BitLocker, you should have a 48-digit recovery key. This key might be saved in your Microsoft account, printed out, or stored on a USB drive. You can check your Microsoft account online to see if the key is saved there.
Use BitLocker Recovery Tool: If you can’t find the recovery key, you can use the BitLocker Recovery Tool. This tool can sometimes help you recover the key if it’s stored on your computer.
Professional Data Recovery Services: If none of the above methods work, you might need to contact a professional data recovery service. They have specialized tools and expertise to recover data from locked or damaged drives.
Contact Manufacturer Support: Sometimes, the manufacturer of the external hard disk can provide additional support or tools to help you unlock the drive.
It’s important to avoid trying random passwords or using third-party software that isn’t reputable, as this can lead to data corruption.
