bromberg Posted February 25, 2016 Share Posted February 25, 2016 I needed to restore data on my 500 GB HDD after a (Vista) system problem occurred which forced me to reinstall my OS. After 66+ hours of processing, RECUVA (my recovery software) requested that I attach an HDD with a capacity of 2.6 TB (!?!) that it needed to recover my data.Why would RECUVA request 5 times the amount of space to recover my data (when I never even used all of the original 500 GB) ?!?Thanks,Dan Link to comment Share on other sites More sharing options...
Moderators Augeas Posted February 25, 2016 Moderators Share Posted February 25, 2016 When files are deleted the entry for them in the MFT still contains the addresses of the clusters allocated to them. These clusters may well have been reused to a greater or lesser extent by new file allocations. Furthermore several deleted files may have been allocated the same clusters, in part or in full. So a great many clusters may be allocated to multiple files, giving a total exceeding the device capacity. A deep scan may also add to the multiple cluster counting, but I'm not sure how or if Recuva accounts for this. As you've found almost 6 million files this could well be the case.

Moderators Nergal Posted February 26, 2016 Moderators Share Posted February 26, 2016 In short, you need to not try to recover "everything" Your data is important, take the time to search the results and find what you need to recover. Just looking at your screenshot there isn't a single one of the files in that particular window that would do you any good if you brought it back from the dead. Uncheck everything Scroll down the list and when you come across a document you need or a cherished photographs place a checkmark Prioritize files with a green dot over a yellow dot, and a yellow dot over a red one. ADVICE FOR USING CCleaner'S REGISTRY INTEGRITY SECTION DON'T JUST CLEAN EVERYTHING THAT'S CHECKED OFF. Do your Registry Cleaning in small bits (at the very least Check-mark by Check-mark) ALWAYS BACKUP THE ENTRY, YOU NEVER KNOW WHAT YOU'LL BREAK IF YOU DON'T.
