[extfs] fix inodes not being initialized above 4 GB 
* So, as it happens, when assigning the product of two 32-bit variables into a 64-bit one,
  compilers default to being *DUMB* and, against all reasonable expectations, do not perform
  that multiplication as a 64-bit operation (even when the code is compiled as x64). Wow,
  that's really great decision making by compiler designers if I ever saw some... Whoever
  decided that C developers would much rather want truncation and 32-bit overflows, instead
  of the expected *LOGICAL* behaviour of conducting arithmetic operations as 64-bit when the
  result will be assigned to a 64-bit variable, need to be condemned to a lifetime of trying
  to help elderly folks trying to conduct simple computing tasks as a punishment...
  Anyhoo, nt_write_blk()'s offset.QuadPart = block * channel->block_size + nt_data->offset
  was overflowing 32-bit as soon as block * channel->block_size went over the 4 GB mark,
  with the disastrous results one can expect. Considering that this is code we practically
  lifted verbatim from e2fsprogs, I guess e2fsprogs' NT I/O manager was never properly
  tested with anything larger than a 4 GB. Awesome!
* We fix the above by doing what unix_io.c does and setting the 32-bit read/write_blk()
  calls to be wrappers around their 64-bit counterpart (since, once you deal with a 64-bit
  block variable, the computation is conducted as 64-bit).
* Also remove a bunch of stuff we don't need from config.h
* Closes #1396

Build status Coverity Scan Build Status Build contributors Release Licence

Rufus logo

Rufus is a utility that helps format and create bootable USB flash drives.

Features

  • Format USB, flash card and virtual drives to FAT/FAT32/NTFS/UDF/exFAT/ReFS/ext2/ext3
  • Create DOS bootable USB drives, using FreeDOS or MS-DOS (Windows 8.1 or earlier)
  • Create BIOS or UEFI bootable drives, including UEFI bootable NTFS
  • Create bootable drives from bootable ISOs (Windows, Linux, etc.)
  • Create bootable drives from bootable disk images, including compressed ones
  • Create Windows To Go drives
  • Create persistent Linux partitions
  • Download official Microsoft Windows 8 or Windows 10 retail ISOs
  • Compute MD5, SHA-1 and SHA-256 checksums of the selected image
  • Twice as fast as Microsoft's USB/DVD tool or UNetbootin, on ISO -> USB creation (1)
  • Perform bad blocks checks, including detection of "fake" flash drives
  • Modern and familiar UI, with 38 languages natively supported
  • Small footprint. No installation required.
  • Portable
  • 100% Free Software (GPL v3)

Compilation

Use either Visual Studio 2019 (version 16.0 or later with SDK 10.0.18362 installed) or MinGW and then invoke the .sln or configure/make respectively.
