Understanding USB To SPI

Caring for USB drives involves avoiding falls or blows, humidity, magnetic fields and extreme heat. In some systems the writing is done on a through a write cache to speed up the time, but if the unit is removed before the system saves the contents of the write cache this can cause discrepancies in the existing file system on the USB stick that could generate data loss.

To reduce the risk of data loss, the write cache is disabled by default for external drives in Windows operating systems from Windows XP, but still a write operation can take several seconds and not physically unplug the unit until it is completely finished, otherwise, the write data is lost. Although USB to SPI memory is not damaged, the affected files can be difficult or even impossible in some cases to recover. Deletion or formatting of file system becomes necessary in order to reuse. So the extraction must be done carefully.
