The third-party software which is not downloaded from App Store is regarded as unsafe tool by Mac OS. When you run this software, you have to input the account login password to past verification of Mac OS.

These files without correct file names or folder structures must be found by RAW Recovery, which is much reliable and useful while the file directory info of lost files has been damaged. If the recovered files with correct file names cannot be opened or they cannot be found by file names or folder structures, please check every file with random names to get lost data back.

The drive cannot be accessed if it's not mounted. Please try to mount it in Disk Utility, then run EaseUS Data Recovery Wizard and scan the Disk to recover lost data.

EaseUS Data Recovery Wizard offers data filter and search functions. You can filter the files by size and type, or search them by file/folder name or file extension. Please refer to this link:

Make sure the network connection is unblocked and click Check for Updates in EaseUS Data Recovery Wizard on the top-left corner of the Mac. Then you are able to download the latest Trial version for replacement.

The Erase (formatting) function in Mac OS just recreates the file directory info and makes the drive space show as empty. But the data area is actually not touched or damaged. You can still recover the lost files with EaseUS Data Recovery Wizard.

However, the Low-Level (physical) formatting initializes the entire disk area. All of the data contained in the disk is erased, , preventing any future recovery attempts.

Please follow the steps below to troubleshoot the reason that causes this issue:

1. For your reference, the deep scan can be completed in around 10 to 12 hours for a 1-TB healthy hard drive in general conditions. If your scanning time is in this time range, please wait patiently and do not stop the scan in the middle of the process.

2. For some reasons, the hard drive is disconnected from the computer, especially for external ones. To fix this issue, please change a new cable and do the recovery again.

3. Your hard drive contains a serious physical error (such as bad sectors, bad tracks). Please use a professional tool to diagnose your hard drive. If the diagnosis shows physical error, you may need assistance from a local data recovery lab.

This error is mainly caused by an unstable connection during the scan or the failure occurred when our product tries to read the sectors on your hard drive. Please follow the steps below to fix it:

1. Safely remove your storage device and reconnect it. Please make sure not to close our program when you try this method.

2. Switch to another USB port or change a new cable.
