Get rid of windows

Get rid of windows-general Linux technology-Linux technology and application information. The following is a detailed description. Today, I decided not to use windows anymore on my computer! Actually, I already wanted to format it!

This filesystem will be automatically checked every 38 mounts or
180 days, whichever comes first. Use tune2fs-c or-I to override.

Tune2fs is an important file system adjustment tool in linux. Several options are described as follows:

-C: Run fsck to check the file system after the number of mount times reaches the specified value.
-I: Check Interval of the file system. When the time interval is reached, the system automatically checks the file system.
-L: displays many parameters of the file system.
-J: Convert to ext3 file system.

Normally, if you use the ext3 file system, use-c 0 to disable the file system check after the number of mounts reaches. However, it is best to use the-I Startup Check Interval at this time, otherwise it is difficult to remedy problems in the file system. My settings are-c 1 w, which is automatically checked once a week.

[Root @ localhost ~] # Tune2fs-I
Tune2fs 1.40.2 (12-Jul-2007)
Tune2fs: The option requires a parameter -- I
Usage: tune2fs [-c max_mounts_count] [-e errors_behavior] [-g group]
[-I interval [d | m | w] [-j] [-J journal_options]
[-L] [-s sparse_flag] [-m reserved_blocks_percent]
[-O [^] mount_options [,...] [-r reserved_blocks_count]
[-U user] [-C mount_count] [-L volume_label] [-M last_mounted_dir]
[-O [^] feature [,...] [-T last_check_time] [-u uuid] device

When linux not safe reboot the ram information will keep in it
