Hi, yes I have. They tried to help me. They said this version has some issues and Asked me to update the firmware but it has been updated.

I tried that it in windows but still not working.

Last option is erase it but I don’t want to erase and format it now because i need all my photos on it. I just struggling to find an app to recover my photos then i need Scandisk to exchange it for me.

I received an email yesterday that said you would close my case if i didn’t get back to your email in 24 hours and I replied immediately. Could you please let me know when your support team will respond to me ? and What can i do ?

Thanks

I’m sorry you’ve lost the data on your external drive. It’s frustrating, especially if you have important photos or other files on it. Firstly, If your MacBook can’t read the drive, connect it to another computer, such as a Windows PC.
A Photo Recovery tool can help you recover the photos from your SSD and bring them back. I recommend Stellar Photo Recovery software, which I have used to recover my deleted videos from my drive. You can try the free version to check the recovery options for yourself.

Oggetto: Il mio Sandisk extreme pro ssd 2TB modello SDSSDE81-2T00 serie 2301KA400304, acquistato da due settimane, mi sta causando moltissimi problemi con il MAC 24" :
Ho scaricato circa 40.000 foto da iCloud ed erano tutte difettose. Il MAC non mi faceva espellere la SSD e ho dovuto fare una rimozione forzata perdendo tutti i dati e foto.
Il file APFS non funziona e chiedo assistenza per l’aggiornamento. Mi dicono che devono essere aggiornati i file ma dopo una settimana che ho contattato il servizio clienti, ancora non ho una risposta. Proverò a chiede il rimborso della SSD perché non è corretto mettere in commercio un prodotto che non funziona con il MAC OS Sequoia 15.6.1

Ciao @Folucree, immagino quanto possa essere frustrante aver appena acquistato l’SSD e aver perso così tante foto. Ci sono un paio di cose che puoi provare prima di rinunciare all’unità:

  • Su un Mac, a volte l’SSD può essere montato in modalità di sola lettura tramite Terminale, in modo da poter copiare i file prima di riformattarlo.
  • Se questo non funziona, un programma di recupero (Stellar Data Recovery, ecc.) potrebbe comunque essere in grado di recuperare le tue foto anche se il file system sembra danneggiato.
  • Dato che hai già aperto un caso di assistenza e non hai ricevuto risposta in una settimana, ti consiglio di ricontattare l’assistenza SanDisk e di fare riferimento al tuo numero di ticket in modo che non lo trascurino.

Se l’SSD continua a non funzionare correttamente con macOS Sequoia, dovresti assolutamente richiedere un rimborso o una sostituzione in garanzia. E una volta che sei di nuovo operativo, cerca di conservare almeno una copia di backup aggiuntiva in un’altra posizione, per ogni evenienza.

Did you check the format of the external SSD? If the file system is incompatible with macOS, it will not be readable by the Mac. For instance, macOS does not natively support Microsoft’s Resilient File System (ReFS) for reading or writing. If you want to use the SSD on Mac, you will need to reformat it to exFAT, or APFS or HFS+.

If it is not caused by incompatible format, connect your external SSD to another USB cable or USB port and see if Mac can recognize it.

If the issue persists, open Disk Utility, run First Aid to verify the file system and repair any found problems. This should help to resolve issues like an unreadable disk.

If nothing helps, recover your data from the external SSD (if any) then initialize it. ( A related post: Fix The Disk You Attached Was Not Readable by This Computer )

Sorry this happened - losing photos is incredibly frustrating, especially when the drive is relatively new.

That macOS message usually means the file system is corrupted, not that the data is gone. First, don’t format the drive, even if macOS suggests it. Try connecting it to another Mac or a Windows PC to see if it’s detected there. On Mac, open Disk Utility → View All Devices and run First Aid on the drive (not the volume).

If the drive shows up but won’t mount, a data recovery tool that supports macOS can often scan it and recover photos before things get worse. If the data is important, avoid repeated attempts and consider recovery first - very write reduces your chances.
