Is there a reliable and easy-to-use Win32 Disk Imager alternative? Yes, in fact, AOMEI Backupper Standard is such a backup utility you need. It allows you to backup removable drives (eg: USB drive or SD card) and other storage devices like hard disk drives (HDDs) and solid state drives (SSDs), and it is even better if the device you want to backup is a system disk.
Also, you can try Event trigger or USB plug in on the professional version. However, this may result in an insufficient disk space issue due to accumulated backups unless you delete old backup images.
For example, you can backup only changed data on the removable via incremental and differential backup. Also, you can clone system disk and then directly use it to boot your computer when it fails. Download it now to discover more!
It is recommended to keep backups of important files. It is easier to make a full backup of a disk or external storage device. This tool helps you to achieve it. When you want to create a duplicate file from a storage device then Win32 Disk Imager is the best option. The storage device can be either an external hard disk or a USB device. All the tool helps is to provide a backup so as to avoid any loss of data in case of system failure.
Win32 Disk Imager (Image Writer for Windows) is a package to help create disk images to save to DVDs/CDs, USB-connected devices like floppy disk drives and USB flash drives. A raw image file is often used for backup purposes and this can be easily saved to various types of media. It is suggested by the developers that a test file should be saved to the ideal media and then verified for data integrity by using a MD5 or other checksum to verify that the file was saved successfully and is intact. Once this is performed, it is the presumed to be a successful media for the Win32 Disk Imager package to write to. Open-source, based at SourceForge, with strong ratings.
Win32 Disk Imager is a simple disk imaging utility to write IMG files to SD and USB cards and allow booting from these devices. Just point to the IMG file and then select the removable device to write to.Note that this utility is intended for flash media and cannot burn CD-ROMs.Note: We recommend reading information available on the author's website before use. Use care with imaging tools like this one.
Image for Windows is a disk imaging utility for Microsoft Windows developed by TeraByte Unlimited. When first released in 2002, it was one of two disk imaging software products that could create a consistent point-in-time backup of Windows while Windows was running.
This program is designed to write a raw disk image to removable SD or USB flash devices or backup these devices to a raw image file. It is very useful for embedded development, namely Arm development projects (Android, Ubuntu on Arm, etc). Anyone is free to branch and modify this program. Patches are always welcome.

Just a note to let you know that after a catastrophic failure of my XP machine, I was able to create a boot disk on my Windows 7 machine and successfully restore the complete drive from a previous backup on an external drive. Great program! Thanks very much.
One feature of Windows NT/2000's (Win2K) C2-compliance is that itimplements object reuse protection. This means that when an applicationallocates file space or virtual memory it is unable to view data thatwas previously stored in the resources Windows NT/2K allocates for it.Windows NT zero-fills memory and zeroes the sectors on disk where a fileis placed before it presents either type of resource to an application.However, object reuse does not dictate that the space that a fileoccupies before it is deleted be zeroed. This is because Windows NT/2Kis designed with the assumption that the operating system controlsaccess to system resources. However, when the operating system is notactive it is possible to use raw disk editors and recovery tools to viewand recover data that the operating system has deallocated. Even whenyou encrypt files with Win2K's Encrypting File System (EFS), a file'soriginal unencrypted file data is left on the disk after a new encryptedversion of the file is created.
The only way to ensure that deleted files, as well as files that youencrypt with EFS, are safe from recovery is to use a secure deleteapplication. Secure delete applications overwrite a deleted file'son-disk data using techniques that are shown to make disk dataunrecoverable, even using recovery technology that can read patterns inmagnetic media that reveal weakly deleted files. SDelete (SecureDelete) is such an application. You can use SDelete both to securelydelete existing files, as well as to securely erase any file data thatexists in the unallocated portions of a disk (including files that youhave already deleted or encrypted). SDelete implements the Departmentof Defense clearing and sanitizing standard DOD 5220.22-M, to give youconfidence that once deleted with SDelete, your file data is goneforever. Note that SDelete securely deletes file data, but not filenames located in free disk space.
SDelete is a command line utility that takes a number of options. Inany given use, it allows you to delete one or more files and/ordirectories, or to cleanse the free space on a logical disk. SDeleteaccepts wild card characters as part of the directory or file specifier.
Securely deleting a file that has no special attributes is relativelystraight-forward: the secure delete program simply overwrites the filewith the secure delete pattern. What is more tricky is securely deletingWindows NT/2K compressed, encrypted and sparse files, and securelycleansing disk free spaces.
Compressed, encrypted and sparse are managed by NTFS in 16-clusterblocks. If a program writes to an existing portion of such a file NTFSallocates new space on the disk to store the new data and after the newdata has been written, deallocates the clusters previously occupied bythe file. NTFS takes this conservative approach for reasons related todata integrity, and in the case of compressed and sparse files, in casea new allocation is larger than what exists (the new compressed data isbigger than the old compressed data). Thus, overwriting such a file willnot succeed in deleting the file's contents from the disk.
To handle these types of files SDelete relies on the defragmentationAPI. Using the defragmentation API, SDelete can determine preciselywhich clusters on a disk are occupied by data belonging to compressed,sparse and encrypted files. Once SDelete knows which clusters containthe file's data, it can open the disk for raw access and overwrite thoseclusters.
Cleaning free space presents another challenge. Since FAT and NTFSprovide no means for an application to directly address free space,SDelete has one of two options. The first is that it can, like it doesfor compressed, sparse and encrypted files, open the disk for raw accessand overwrite the free space. This approach suffers from a big problem:even if SDelete were coded to be fully capable of calculating the freespace portions of NTFS and FAT drives (something that's not trivial), itwould run the risk of collision with active file operations taking placeon the system. For example, say SDelete determines that a cluster isfree, and just at that moment the file system driver (FAT, NTFS) decidesto allocate the cluster for a file that another application ismodifying. The file system driver writes the new data to the cluster,and then SDelete comes along and overwrites the freshly written data:the file's new data is gone. The problem is even worse if the cluster isallocated for file system metadata since SDelete will corrupt the filesystem's on-disk structures.
The second approach, and the one SDelete takes, is to indirectlyoverwrite free space. First, SDelete allocates the largest file itcan. SDelete does this using non-cached file I/O so that the contentsof the NT file system cache will not be thrown out and replaced withuseless data associated with SDelete's space-hogging file. Becausenon-cached file I/O must be sector (512-byte) aligned, there might besome leftover space that isn't allocated for the SDelete file evenwhen SDelete cannot further grow the file. To grab any remaining spaceSDelete next allocates the largest cached file it can. For both ofthese files SDelete performs a secure overwrite, ensuring that all thedisk space that was previously free becomes securely cleansed.
On NTFS drives SDelete's job isn't necessarily through after itallocates and overwrites the two files. SDelete must also fill anyexisting free portions of the NTFS MFT (Master File Table) with filesthat fit within an MFT record. An MFT record is typically 1KB in size,and every file or directory on a disk requires at least one MFT record.Small files are stored entirely within their MFT record, while filesthat don't fit within a record are allocated clusters outside the MFT.All SDelete has to do to take care of the free MFT space is allocatethe largest file it can - when the file occupies all the available spacein an MFT Record NTFS will prevent the file from getting larger, sincethere are no free clusters left on the disk (they are being held by thetwo files SDelete previously allocated). SDelete then repeats theprocess. When SDelete can no longer even create a new file, it knowsthat all the previously free records in the MFT have been completelyfilled with securely overwritten files.
The reason that SDelete does not securely delete file names whencleaning disk free space is that deleting them would require directmanipulation of directory structures. Directory structures can have freespace containing deleted file names, but the free directory space is notavailable for allocation to other files. Hence, SDelete has no way ofallocating this free space so that it can securely overwrite it. 2b1af7f3a8
