I lost weight in the middle of the 360 system and collapsed. I lost two disks when I restarted. I can't find the drive letter and there is no file. How can I remedy it? . .
See if you can find a recovery software to recover part of it, and then repartition and format the hard disk to reinstall the system. Generally, do not use these softwares to clean or update drivers, which will lead to system anomalies. Be careful not to mess up at ordinary times, just check regularly whether there is malicious software uninstall.
