HFS+ volume header and data recovery

[alex4478]

Hi,

Quick question, if the volume header is written 1024bytes from the beginning and end of a drive. Then how does a data recovery program get the folder structure back when a drive is reformatted with a hfs+ file system again?

GO WITH R- STUDIO

R-Studio isn't able to rebuild the file/folder structure of a hfs+ formatted drive.

Think this way, you got a BOOK without INDEX (& page numbering)
in order to sort things out, you HAVE TO READ THE FULL DAMN PAGES and SORT it somehow back

(RAW results means no page numbers = results based on FILE SIGNATURE) which ANY stupid app will find

usually you will have RAW @80% and 20% for original names/structure

Hi ,
Someone has already explained you your question ,But try 3 different tools in the case ,You might get better results in at least 1 of it

Looks like the catalog file mostly survived. Better to try DataRescue using Mac computer. But there is no a program that could to reconstruct original fs completely. Only by hands with according knowledge, probably.

i disagree, the catalog is probably overwritten by the new catalog file. At least partially, but in my experience a very large area is preallocated and zero filled for the new catalog, so in many cases the only option is raw recovery.

What Einsten said, but with another add-in. The pages may not be in the right order.

At least, there is no punishment for attempt. He can be lucky, if format process has stopped before finish. I saw several times when it was possible to get good result after format. Hope the format process didn't complete.
