If your Mac comes packed with a hard disk drive (HDD), chances of file recovery are high. When a file or folder is removed from Mac’s hard drive, only the title data is purged; the file itself still rests somewhere on the HDD. If you continue using your Mac, the vacant disk space will be written over after saving new items.
If your Mac comes packed with an internal or external solid-state drive (SSD), things may not be that easy. Recovering files from external hard drive on Mac may require using the special third-party software. SSD storage devices have a different data management system (TRIM): after the file is erased, it becomes unrecoverable. The TRIM system wipes the unused data on the SSD internally, so the chances of data recovery are slim. Making regular data backups is recommended to prevent data loss.
Before you start any cumbersome data recovery procedures, check if there are any file copies stored on different mediums. Multiple devices can sync data owing to the cloud technology. Thus, discovering the erased files on other devices synced under a single user account is possible. If you’re using iCloud Drive, Dropbox, or Google Drive, the chances of file recovery are high. It’s worth checking the iPhone gallery or SD card for erased photos and video. As for the work files, they can be saved in the sent mailbox, if you have sent them to your colleagues.
