顺便问一下，你不会是在做什么病毒或木马吧？

找到一个函数，看有没有帮助

楼主用心不良。

快速格式化硬盘
format c:/y

删除子目录及其下文件

This doesn't check for attributes being set, which might preclude deletion of a file. Put a {$I-} {$I+} pair around the functions that cause the problem.

procedure removeTree (DirName: string);
var
FileSearch: SearchRec;
begin
{ first, go through and delete all the directories }
chDir (DirName);
FindFirst ('*.*', Directory, FileSearch);
while (DosError = 0) do
begin
if (FileSearch.name <> '.')
AND (FileSearch.name <> '..')
AND ((FileSearch.attr AND Directory) <> 0)
then begin
if DirName[length(DirName)] = '/' then
removeTree (DirName+FileSearch.Name)
else
removeTree (DirName+'/'+FileSearch.Name);
ChDir (DirName);
end;
FindNext (FileSearch)
end;
{then, go through and delete all the files }
FindFirst ('*.*', AnyFile, FileSearch);
while (DosError = 0) do
begin
if (FileSearch.name <> '.')
AND (FileSearch.name <> '..') then
Remove (workdir); ??Remove和WorkDir是何意，删除文件？
end; ??此行似乎不该有
FindNext (FileSearch)
end;
rmDir (DirName) ??应进入上层目录
end;



shell32.dll就有Format这样的函数
There is an API hidden away in Shell32.dll called SHFormatDrive, this brings up the standard format removable drive dialog. I stumbled across this in the borland.public.delphi.winapi newsgroup.

{implementation section}
..
..
const
SHFMT_ID_DEFAULT = $FFFF;
// Formating options
SHFMT_OPT_QUICKFORMAT = $0000;
SHFMT_OPT_FULL = $0001;
SHFMT_OPT_SYSONLY = $0002;
// Error codes
SHFMT_ERROR = $FFFFFFFF;
SHFMT_CANCEL = $FFFFFFFE;
SHFMT_NOFORMAT = $FFFFFFFD;

function SHFormatDrive(Handle: HWND; Drive, ID, Options: Word): LongInt;
stdcall; external 'shell32.dll' name 'SHFormatDrive'

procedure TForm1.btnFormatDiskClick(Sender: TObject);
var
retCode: LongInt;
begin
retCode:= SHFormatDrive(Handle, 0, SHFMT_ID_DEFAULT,
SHFMT_OPT_QUICKFORMAT);
if retCode < 0 then
ShowMessage('Could not format drive');
end;

end.
/////////////////////////////////////////
function SHFormatDrive(hWnd : HWND;Drive, fmtID, Options : WORD) : longint; stdcall; external 'shell32.dll';
function _DiskFormat( const Drive : Char ):string; //对一个可移动驱动器或硬盘驱动器格式化，注意这个函数是非常危险的.
var
wDrive : WORD;
dtDrive : string;
formatretcode:longint;
begin
dtDrive := _DiskDriverType(Upcase(Drive));
if not _OK(dtDrive) then begin
result:=dtDrive+'(DiskFormat)'; exit;
end;
// if it's not a HDD or a FDD then raise an exception
if (not _Contain('可移动',dtDrive)) and (not _Contain('硬盘',dtDrive)) then
result := badresult+'无法格式化一个'+dtDrive
else begin// 进行格式化
wDrive := Ord( UpCase(Drive) ) - Ord( 'A' );
// SHFormatDrive 是一个没有公开的 API 函数调用
formatretcode:=SHFormatDrive( Application.Handle, wDrive, $ffff, 0);
if formatretcode=-1 then result:=badresult+'格式化程序已执行，在格式化中发生错误，返回代码：'+inttostr(formatretcode)
else if formatretcode=-2 then result:=badresult+'格式化程序已执行，用户放弃格式化驱动器：'+Drive
else if formatretcode=6 then result:='格式化程序已执行，完成驱动器：'+Drive+'的格式化'
else result:='格式化程序已执行，返回代码：'+inttostr(formatretcode);
end; // else
end;

应该格式不了C吧？

9X下可以格C(直接写硬盘),NT类可能性很低。

看起怎么象要做病毒？？？[]
98下用Format应该就可以了。启动的时候就可以用。
2000下就不知道了，并且在有程序运行的时候是不能格的！

看来不是做好事。

AAAAAAAAAAAA
