While there is no standard official version explicitly named "Win64 Disk Imager," the widely used Win32 Disk Imager is fully compatible with 64-bit Windows. If you are looking for a "useful feature" or a more modern alternative that offers functionality beyond basic reading and writing, consider the following features found in updated disk imaging tools: Advanced & Useful Features

Modern alternatives like balenaEtcher and dotNet Disk Imager provide features that the original tool lacks: dotNet Disk Imager download | SourceForge.net

Features * RAW and ZIP disk images reading, writing and verification. * On the fly zip support, completely native and in-memory. * SourceForge Iperius Backup

Here’s a concise review of Win64 Disk Imager (often just called Win32 Disk Imager, but compatible with 64-bit systems).

Pro Tip: Compressing Backups

Since a raw 64GB backup is huge, you should compress it:

1. After the "Read" completes, right-click the resulting .img file.
2. Select "Send to" > "Compressed (zipped) folder."
3. Win64 Disk Imager can later read compressed images directly (though slower).

Procedure

1. Insert your target USB/SD card into the PC.
2. Launch Win64 Disk Imager as Administrator.
3. Select Image File: Click the folder icon next to "Image File". Navigate to your .img file.
4. Select Device: In the "Device" dropdown, triple-check you have selected the correct drive letter (e.g., E:\).
   Tip: Open Windows Disk Management (diskmgmt.msc) to confirm which disk matches the removable drive.
5. Write: Click the Write button.
6. Confirm: A dialog will warn "All existing data on selected device will be overwritten." Click Yes.
7. Wait: Progress bar fills. Time varies (2–20 minutes). Do not unplug the drive.
8. Success: "Write successful" message appears. Click OK, then close the tool.

2. Download & Installation

• Official Source: sourceforge.net/projects/win32diskimager/
• Version: Look for the .exe file labeled for 64-bit Windows (e.g., Win32DiskImager-1.0.0-binary.zip or .exe).
• Installation: No formal installer exists. Extract the .zip file to a folder like C:\Tools\Win32DiskImager. Run Win32DiskImager.exe as Administrator (right-click → Run as administrator).

Error 5: The image is bigger than the SD card (Backup restore)

• Cause: You backed up a 32GB card with a 7GB OS. The .img is 32GB. Your new card is 31.9GB.
• Fix: Do not use Win64 Disk Imager for restoring to slightly smaller cards. Use dd or Rescuezilla. Or, use a larger replacement card.

Part 1: What is Win64 Disk Imager? (The 64-Bit Evolution)

First, let’s clear up a common point of confusion.

Win64 Disk Imager is the 64-bit native version of the legendary Win32 Disk Imager. The original software was written for 32-bit systems, limiting its ability to address large amounts of RAM or handle massive storage devices efficiently.

Key features

• Write image files to removable drives.
• Create image files by reading raw data from a drive.
• Verify written images by comparing source and target.
• Simple GUI with drive selection and progress display.
• Supports large images for 64-bit Windows.
