Why a SanDisk Drive Corrupted on a Mac

When the cause of SanDisk flash drive corruption is bad blocks, it means the flash-based storage devices are split into enormous chunks of tiny blocks, which have the shortest lifespan and may stop working any time after the lifespan is over.

Besides, the disk error, such as " error 49244", will prevent you from accessing the stored data on the external drive on your Mac.

Similarly, when the cause of SanDisk flash drive corruption is imprecise removal, there's a top-notch reason why modern OSs encourage customers to eject their SanDisk USB drives safely. If you don't maintain the safe disposal of your USB drive, it may lead to damage because of sudden interruption of reading or writing data.

On the other hand, when the corruption is due to power outages, if your SanDisk flash drive isn't obtaining adequate power, or if you face a power outage, there would be the highest chance of data being corrupted because of their interrupted transfer.

Another cause of flash drive corruption is software bugs in OS, apps, and drivers, which prevent files from being saved precisely or corrupting the file system's integrity.

Lastly, if there's any physical damage on your SanDisk drive, it may compromise the proficiency of a USB flash drive to maintain a stable connection, which leads to corruption. A corrupted drive can wipe out the data in your MacBook.
