M1 chip structures so different from the Intel chip, an M1 chip has far higher security than the Intel chip. So when you use Cisdem Data Recovery to recover files from a Mac with M1 chips, you will receive a message like below

Part 5 Recover lost data with RAW recovery

What is RAW recovery?

Cisdem Data Recovery rebuild the lost files in the following 2 methods, and the scan result will separately list under Files with Directory and Files without Directory.

1. Locate the files through File Directory Info

The scan result will list under “Files with Directory”, and the file’s directory info (file name, path and created/modified time) will be included.

2. RAW recovery

The scan result will list under “Files without Directory”, and the file’s directory (file name, path and created/modified time) will be lost and replaced as random numbers.

So if you cannot locate the lost data by searching with the file’s name under Files with Directory, or you found it but cannot open it after recovering, you can then have a try under the Files without Directory.

 

How to fast locate lost data via RAW recovery?

Since the files found by Raw Recovery comes with a random name, it seems that you have to check all the files one by one to see if your lost data is included, which will cost a huge amount of time to confirm all the listed files. Here we will show you 2 tips to help you fast locate the lost data.

1. Locate the lost data based on the file extension and file size.

Enter the file extension in the search box, and then sort the listing files by size, double click to preview the listing files to locate the target file to recover it.

2. Filter the files by tags and locate the lost data.

The files under this tab will be reorganized by file types if there is no file system information can be retrieved. For example, Camera includes the photos and videos, Office includes the word and excel files, etc. And there will be sub-folders if the program detects more information like the device you used to shoot the photos/videos, which will further help you locate the right files you need.

 

Part 6 Solutions for the drive not being detected

Usually when you run Cisdem Data Recovery, you can see all the drives listed on the left panel of the main interface, if the target drive is not listed there, you may find a solution here.

Please go to Applications folder > Utilities folder, find the app Disk Utility, and double click to open it, all the devices will be listed under Disk Utility,  please check if the target drive is listed here.

Case 1: The device is "Not Initialized".

Generally, when you connect a "Not Initialized" drive, Mac OS will auto pop-up a window to ask you to Initialize the drive, you can directly click "Initialize" in the pop-up window or go to Disk Utility to initialize the drive, after that, you can run Cisdem Data Recovery for Mac to scan the drive.

Note:

1. The data is still recoverable after you initialize the disk, the Initialization only re-allocate the disk so it can be reformatted.

2. Even if you are failed to initialize the disk, you are still able to use Cisdem Data Recovery to scan the disk, just click Ignore and start scanning your disc.

Case 2: The device is "Grey Out".

If the device is grey out in Disk Utility, it's probably hidden for some reasons. Right click on this drive and choose "Mount" option to mount the drive, then check if it will be detected.

However, if it does not work, please select the drive and click "Repair Disk" to fix the disk error, then try to run Cisdem Data Recovery again.

Case 3: The issue with the USB Port or USB Cable.

If it is an external device and cannot be detected by Disk Utility at all, please check the connections between the external drive and your Mac to see if the connection is poor or loose. 

1. Try to re-plug the external drive to see if it shows up in Disk Utility.

2. Try another USB cable to connect between the external drive and Mac.

3. Try to connect the external drive with another USB port on your Mac.

4. Try to restart your Mac to see if it will show up in Disk Utility.

If the drive still cannot be detected in Disk Utility, please check the power supply. Single USB ports can provide only 5V. In that case, make use of USB cable having one USB connection for the external drive and two for Mac. This will supply the power required by the external hard drive.

Notes:
If none of the methods above works, you probably need to send the drive to manufacturer or local hardware maintenance lab for an overhaul.
