【 Weak current College 】 why each boot file system checking occurs on E

I believe many people have come across a computer after power on
“CheckingfilesystemonE:
ThetypeofthefilesystemisNTFS…… And then there are some figures, the last line is similar to "?? Allocationunitsavailableondisk ", then enter the system desktop".

This is generally a non-graceful shutdown, power off, press the start key to start the heat, or press the power key off the post.

Due to the shutdown of the program E-disc is still running, each boot hard disk will automatically post to eliminate the error message, and if a non-graceful shutdown the program does not exit, then the next time you boot the computer to perform a self-test from new to eliminate eliminate error messages, normal computer once, the next time that you start is not the case.

If each boot all happen there are 2 possibilities: one is the hard disk has bad road, this may be hard drives are already poor, suddenly come across illegal shutdown, disk read and write head due to the impact of the emergency electric current, resulting in a collision with a hard disk, the hard left a bad road, but also be able to use the computer, this is the case generally can only replace the hard drive. A computer is not a problem, but leave the memory of the information, the result self-test every time, eliminate way is: start-to-run, enter chkdskE:/x/f carriage return, and then appeared a dos window automatically-running, and so he ran without problems.

ChkdskE:/x/f mean Windows found E plate there is a problem with the file system
Running CHKDSK <使用选项/x/f> to correct fix these problems

The full name is checkdisk chkdsk is the disk check, it is when your system error or illegal shutdown when called by the system to check the disks. Based on the file system, creates and displays the disk's status report. Chkdsk also lists and corrects errors on the disk.

/x
First of all to force uninstall the drive volume, which drives all open handles are invalid,/x/f also contains a function.

/f
Fix disk errors.
You must lock the drive disk breaks, if chkdsk cannot lock the drive disk breaks, then you will see a message asking whether you want the next time you restart the computer to check the drive.

Question mark (?) is a computer with screen appears for some numbers, and local computer hard disk partitions and file sizes, different computer digital is not the same but mean different

For the FAT file system, you can use win its own disk repair to an operation, right-click the drive letter you want to work, property-error-checking tool, select the automatically fix errors check on, click Start.
