Как бы я мог стереть определенный сектор моего жесткого диска с Windows? Я имею в виду жесткий диск в использовании ...
Либо стереть с нулями, либо заменить случайными данными. Есть ли сценарий или программа, которая может сделать это надежно при запуске Windows? Я использую 64-разрядную версию Windows 7, а сектор, который я хочу стереть, - это сектор 62. Может ли Winhex?
Я написал один для вас:
#include <stdio.h>
#include <limits.h>
#include <wchar.h>
#include <io.h>
#include <tchar.h>
#include <Windows.h>
#define _O_U16TEXT 0x20000

HMODULE hKernel32 = LoadLibrary(_T("kernel32.dll"));
__try
{
BOOL (WINAPI * pIsWow64Process)(HANDLE, PBOOL) = (BOOL (WINAPI *)(HANDLE, PBOOL))GetProcAddress(hKernel32, "IsWow64Process");
if (pIsWow64Process != NULL)
{
BOOL isWow64;
if ((*pIsWow64Process)(GetCurrentProcess(), &isWow64) && isWow64)
{
PVOID old;
return ((BOOL (WINAPI*)(PVOID*))GetProcAddress(hKernel32, "Wow64DisableWow64FsRedirection"))(&old) ? old : NULL;
}
}
}
__finally { FreeLibrary(hKernel32); }
return NULL;
}
int _tmain(int argc, TCHAR *argv[])
{
_setmode(_fileno(stdout), _O_U16TEXT);
DisableWow64FsRedirection();
if (argc == 1 + 3)
{
long long offset, length;
int a = _stscanf(argv[2], _T("%lld"), &offset);
int b = _stscanf(argv[3], _T("%lld"), &length);
if (a == 1 && b == 1)
{
HANDLE hFile = CreateFile(argv[1], FILE_READ_ATTRIBUTES | FILE_WRITE_DATA, FILE_SHARE_READ | FILE_SHARE_WRITE | FILE_SHARE_DELETE, NULL, OPEN_EXISTING, FILE_FLAG_RANDOM_ACCESS, NULL);
if (hFile != NULL && hFile != INVALID_HANDLE_VALUE)
{
__try
{
PBYTE pMem = (PBYTE)calloc((size_t)length, sizeof(BYTE));
//Assume we had enough memory...
__try
{
DWORD nw;
OVERLAPPED ov = {0};
ov.Offset = (DWORD)(offset & ULONG_MAX);
ov.OffsetHigh = (DWORD)((offset >> (CHAR_BIT * sizeof(ov.Offset))) & ULONG_MAX);
if (WriteFile(hFile, pMem, (DWORD)length, &nw, &ov))
{
SetLastError(ERROR_SUCCESS);
}
else { _ftprintf(stderr, _T("Error writing data: %d"), GetLastError()); }
}
__finally
{

}
__finally { CloseHandle(hFile); }

}
}
else

_tprintf(_T("Usage:\n wipe <file> <start> <length>"));
}
return GetLastError();
}

Вы можете просто запустить его так:
wipe \\.\PhysicalDrive0 0 512
где первый аргумент - имя файла, второй - смещение, а третий - количество байтов. Количество байтов, вероятно, не может быть больше ~ 63 МБ.
Конечно, не вините меня, если вы случайно удалили диск ...
