Volume serial number
This package provides many functions, but most important are
GetVolumeSerialNumber and SetVolumeSerialNumber.
These functions use uint64 for storing serial number.
If serial number is 4 bytes long then it uses only 4 low bytes of uint64.
Serial number contains parsed value in native byte order.
To print it in often used format use binary.Write with binary.BigEndian byte order.
Checkout source code for more explanations.
Supported file systems
- FAT12
- FAT16
- FAT32
- exFAT
- NTFS
Supported OS
Windows
Tested on XP 32 bit and Windows 10 32 and 64 bit.
[!Warning] To use these functions drive name must be in format
\\\\.\\C:(this is escaped string).
Linux
Must be supported if you can somehow get right drive path without offset
(with access to FAT/exFAT/NTFS's Boot Sector'). No OS specific functions were
used — only os.Read, os.File.Seek and os.File.Write for disk
manipulations. But untested.
