Go to the C: prompt and type CHKDESK
MD
in command prompt you would type H:/.
There are two ways to scan a hard drive for errors: the normal way or the old-fashioned way. The normal way: Go to My Computer (it might be called just Computer if you've got Windows Vista or 7) and right-click the drive you want to scan. Click Properties in the drop-down menu and then go to the Tools tab. There should be a button labeled "Check Now". You can click this to open the Check Disk utility. The old-fashioned way: Click Start, Programs or All Programs, depending on your OS, then Accessories, Command Prompt. In the command prompt, type in chkdsk c: and press enter. If you don't want to scan your C drive, replace the c with the drive letter that you want to scan. If that doesn't work, try replacing chkdsk with scandisk. If the scan finds errors, try the same thing, only add -f after the c:, for fix errors.
depends on the OS, but for most it is : defrag <DRIVE> example: defrag c:
When in Command(prompt) [Cmd] type: MD C:\Data <enter> It's as simple as that! Note: You must have the permission to create folders on C-drive..
Defrag c:
I believe it simply tells you what drive you are in. Such as C drive or D Drive.
The attrib.exe -s/s command
You simply enter the drive letter followed by a colon. For example, when you start the command prompt, you will be in the C drive. if you want to switch to the D drive, you would type in 'D:' and hit enter: C:\Users\jdoe> D: D:\>
ys c: SYS C:
format /s c: should do the job.
In Windows XP Go to: Start>Programs>Accessories> Command Prompt.At the command prompt enter: format c:/This will format and erase all of the data on the c: drive. If you also have a d: drive then do a format d:/ command before you do the format of the c: drive.Caution: be sure you want all of the data erased as this action is not reversable.
