Fix 1. Recover Data from Lost Partitions on an External Hard Drive with Recovery Software
Have you encountered accidental partition deletion? You can apply professional partition data recovery software - EaseUS Data Recovery Wizard to recover data from lost partitions on an external hard drive. You can download and install this software now, and we'll introduce the detailed steps to help you recover data.

The EaseUS partition data recovery tool makes it easier to recover data from deleted partitions on an external hard drive. You can discover plenty of deleted photos, Microsoft documents, and videos on the external hard drive's lost partition with the help of EaseUS data recovery. This recovery product can also help you recover formatted external hard drives.
Let's start the recovery process now:
Step 1. Select and scan the lost partition
Launch EaseUS Data Recovery Wizard, select "Lost Partition" and click "Scan" to search for all the lost data. If there are many lost partitions, you can identify them through its partition size.
Note: Since the Windows system doesn't support the Linux file system, the Ext2 or Ext3 partition will be recognized as lost partition with no drive letter in the software. If you want to recover data from Ext2/Ext3 partition, you can follow these steps.

Because there will be a lot of scanned files, you can choose a file category for quick filtering, such as Pictures, Videos, Documents, Audio, and Others. Or if you remember the file name, you can just look it up in the search box in the upper right corner.
