After the initial release of the file system, data loss was a common problem however, since then, Apple has addressed it and fixed the bugs.
Method 2: Recover APFS with Stellar Data Recovery softwareĪPFS is a file system released with macOS High Sierra it is optimized for the solid-state drive and flash storage. macOS includes the Time Machine backup software for free.The blog outlines 2 crucial methods to repair APFS storage media & recover the lost data. Backups are extremely important if you value your data. It is becoming very difficult to recover data from external drives these days since many of them integrate the USB port onto the main drive board. Things are even more complicated and difficult with the USB-C Macs. It is impossible to recover accidentally deleted data after the Trash has been emptied plus an SSD can fail at any time without any warning signs (even a brand new SSD). You should always have frequent and regular backups of your computer and all external media which contain important & unique data. Yes it can be done, but you also have to be willing to deal with the fallout when something goes wrong as macOS isn't expecting that configuration and macOS (especially recent versions) does not like surprises.Īlso before performing a major operation like upgrading macOS to a new major version (yes this is considered a major operation) you should always make sure to have a good backup first since things may go wrong. If you did put your user folders onto the external drive (which it looks like you did if you are running Big Sur - hard to be certain since you blocked out important information), then you should know that doing so is risky for multiple reasons. Some data recovery apps may attempt to "fix" or "modify" the drive which is extremely dangerous as it may cause even more problems which could make it even more difficult or even impossible for a professional data recovery service. Of course you can attempt to use data recovery software such as Data Rescue, but you need to be extremely careful and have somewhere to store any recovered data besides the corrupted external drive.
Both vendors provide free estimates and both are recommended by Apple and other OEMs. If you don't have a backup of the data on this drive, then I suggest you contact a professional data recovery service such as Drive Savers or Ontrack. Since First Aid is unable to repair the external APFS volume, then you will need to erase the external drive since there are no third party utilities to repair an APFS volume because Apple has not released the required APFS documentation yet.
