In Ubuntu, the system prompts that the USB flash drive has no permissions but to read and write data.

In Windows, the USB flash drive can read and write files normally (copy and paste files can be copied), but a file cannot be opened. In Ubuntu LInux, U can only read and write the USB flash drive. Tip: Read only system.

1, # tail-f/var/log/syslog To view the dynamic information of the file system

May 19 21:31:28 controller kernel: [284792.451452] FAT-fs (sdb1): Volume was not properly unmounted. Some data may be uploaded upt. Please run fsck.

2. df-h determines the basic information of the USB flash disk.

/Dev/sdb1 15G 7.8G 6.9G 54%/media/Hadoop/disk

3. Run the command: # fsck-C-a/dev/sdb1 to perform automatic repair... the repair is successful, and the files that cannot be opened are intact. I lament the power of linux.
