why the U disk data will be lost
Some friends in the use of U disk when the data is sometimes lost, after writing the data has been saved, but the data is still missing, and the entire document is missing. But the folder is still there, what is the cause of it? Here is a solution for everyone:
The default set of USB disk in normal system is optimized for fast deletion. So the U disk can be any hot plug, there will be no problem. If you specifically set "Optimize for performance", the U disk must be manually aborted by clicking on the icon in the taskbar, so it is generally not as usual to destroy files as normal operations. I think there may be several situations:
1, is reading and writing when pulling a U disk
2, mistakenly deleted, here deleted but no Recycle Bin
3, the disk appears in the bad sector, just the file exists in this area
4, U disk Interface supply voltage is insufficient, resulting in write errors, that is, the error message written to the area
5, poor performance of the chip, memory effect failure.
For the above situation can be gradually excluded, especially the final use of tool software data recovery, and then low-level format, or to the manufacturer's website to flash u disk bios, this is the last resort.
