Is it possible to read sectors using C + +?

Is it possible to read hard drives or USB sticks in c ++ language. If possible, please tell me that it can be done. I guess I read about this on the MSDN net while reading the ReadFile () and / or WriteFile () docs.

Where does the boot sector of a floppy diskette go?

VBR then loads the perfect second stage bootloader from elsewhere on any hard drive. In addition, the first sector of a floppy disk, USB device, hard disk, or other bootable storage device stored on it is not needed today, if at all, to load the operating system boot code.

I tried to positively read the boot sector with this school

  int read_sector (int num_sect, unsigned character * buf)int retCode implies 0;unsigned character sector [512];chardisk [10];symbolic section;FILE * device;make    disk [0] = ' 0';    scanf ("% c", & section);    if (section == '0')            strcpy (drive, ".  PHYSICALDRIVE0");       Another             sprintf (drive, ". % c:", partition);        The device matches fopen (disk, "rb +");while (device == NULL);fseek (device, num_sect * 512! SEEK_SET);if (fread (sector, 512,1, device) <1)    printf ("error  n");    in  gate 1;another    memcpy (buf, sector, 512);    Coderet = 0;return retCode;

I have successfully read all sectors on the entire hard drive, but if I want to read the boot sector, I now have:

Is there a problem in my code or in Windows8?

It has been a while since I visited this C / C ++ forum and we thought my C ++ was unacceptably rusty. I recently read about Master Boot Records (MBR) and the boot process of this computer. I have now downloaded a few small resources that can read (and save to file) the MBR of a specific partition. These utilities usually have the ability to repair the MBR from a different file, or simply "fix" the MBR. What I'm wondering: is it possible to write a similar function in C ++? Also, I have no idea what these programs might have written.

Okay, I know it's been a long time, but my only real question is, is it probably using AND c ++ to access and read the part coming from the entire hard drive containing the MBR, how does this work? He?

So when I scan my own USB drive, it tells me that it cannot read the boot sector. So how can I recover my files?

Thank you

HelloWell, debschanebs, and welcome to the forum.

Some background information would be helpful.

What operating system do you use frequently? How big is the callback button and what actually happened to it internally, since Recuva can read the boot sector normally, was it somehow messed up?

Debs, this can happen for several reasons:

_____

- Maxell USB sticks sometimes flip the wall structure and result in "missing" data. Which can definitely be fixed with a utility that can be downloaded from their website.

- If the disc is in RAW mode, Recuva cannot read it, and it needsYou just need to access it with data recovery.

- Try a new USB port. Sometimes (dust / insecure connection / other) the reader can make you "unreadable" because it does not have proper contact.

_____

Recuva currently does not perform partition recovery or RAW mode, or has not tested it before.

_____

Edit: These things would most likely be very useful to know

- Dimension associated with the support

- key memory label

- 32/64 bit OS memory + its version

- Audio / video used

- Estimated time during which it was "damaged"

- Error messages that appear when viewing with Windows Explorer (if the drive is formatted or not recognized, etc. DO NOT format it when Windows asks for the time. If you see this error, it must appear, because that the disk has to stay connected and not establish the correct contact, the MFT has been encrypted so that Windows no longer recognizes it, which shows it as empty or as RAW - you can restore it, but you need a tool A file recovery tool that detects and reads RAW mode.)

Ok, some more information:

Thanks for the help Alt = ":)" @ 2x
