How to compare hash sets

[s1022.kim]

Hello,

I am trying to clone a drive with 'Create Drive Image' tool on OSForensics.
I successfully cloned it and am looking for comparison tool to compare each hashsets to verify the integrity.
Please let me know how I can compare hash sets.

Thank you for your help in advance!

Under the options to create an image there two interesting settings.
1) A hash function option. This can be used check the entire image is correct at any point in the future. If the hash values match the image is good.
2) A "verify" option (which re-reads the image just created back from the disk to check it against the source image).



This information is saved as a log file in the destination folder. (with the .info.txt file extension). Here is an example log file for the image above.

Image source: \\.\PhysicalDrive1: Partition 0 [100.00MB WIN95 FAT 32]
Source Disk Model Number: Samsung SSD 970 PRO 1TB
Source Disk Serial Number: S5JXNC0N303006K
Image file name: TestImage.img
Image file size: 104857600

You don't need to use a hash "set" for this. As just a single hash value is enough to check the entire image.

But if for some reason you did need to compare the entire contents of the disk, at a file by file level, between two images you could use the "Signatures" module.

I cloned a drive via 'Create Forensic Image' > Create Logical Image > Copy to Folder to an external drive.
In this case, how I can confirm the original data and cloned data are identical?
For example, if I hash the original drive and has the external drive, would two hash values be same? If so, I appreciate how I can hash each drive on OSForensics.
Thank you for your help in advance.

Or could you let me know how I can verify if the data is identical after I run 'Logical Image.'

I cloned a drive via 'Create Forensic Image' > Create Logical Image > Copy to Folder to an external drive.

This is a contradiction.
If you copied one folder, then you did not in fact clone the drive.

If you need to compare the entire contents of the disk, folder or logical image, at a file by file level, between two images you could use the "Signatures" module.
