Disk Images: improved backup into DMG could fail or hang due to specific Safari extensions - Fixed: recovery from Seagate FreeAgent GoFlex disks corrected - Fixed: crash reports are now sent correctly if Disk Drill is installed on Mac OS X 10.8+. The Mac version of Disk Drill Basic provides recovery from HFS/HFS+ and FAT disks/partitions (only the paid Pro version can actually recover files, the Free version will only allow Previewing files). In August 2016, Disk Drill 3 announces support of macOS Sierra. Disk Drill 3 8 204 For Macbook ProDisk Drill – Tester – Hiran Rajkumar C7137759 Location – Leeds Beckett University IME JG204 Critical Review The Disk drill is a powerful and easy to use data recovery application that uses recovery vault technology with a variety of retrieval methods to recover data from a media source and can also be used as a backup utility. The technology itself runs as a background service and making it possible to restore deleted files with their original file names and their true location. However the casualty and easiness of tools works with all recent version of windows and MAC but does not show a file’s condition/quality before recovery. It’s necessity to be installed in the hard drive and no available portable option would be a hindrance to a professional tester. During the implementation and through extensive research the disk drill had few problems that were not available in other DFR tools in the market like Puran file recovery, Recuva and FTK. The quality of a file which needs to be undelete is not shown, which leads to many recovered files being corrupted and unable to open on recovery (UFS Explorer, 2016). Another problem is the installation of the application itself on the system which may over write the data for recovery. Spt_macin_v1.1_bin.tar.gz binary package for mac os. The core engine and the responsive UI is well designed, and presented with extras are useful for a moderate user, but 500MB limit on the beta version is of little help and tools like FTK does a better job with free of charge. It is an intuitive handy recovery application for the everyday windows user but not for the forensic tester. Critical Evaluation Link to Implementation of Disk Drill –. The implementation was done through using Arsenal image mounter, to load the test ‘Images’ on to the drive. These test images were base images used by the National Institute of standards and technology for Deleted file recovery tools. The results have been repeated and reproduced by NIST approved tools like Encase and FTK. ![]() The DISK DRILL being a DFR tool should produce the exact results that have been recorded by NIST. Three images with different file formats (NTFS, EXE, FAT) were used for testing. The test were carried out three times in each file format for the precision under repeatability conditions. This proves that the test result are obtained with the same method on each format inside the same laboratory by disk drill using the arsenal image mounter within short intervals of time. The test was also carried out three time separately in each file format for the precision under reproducibility conditions. This proves that the test results are obtained with the same testing method used above with disk drill using the arsenal image mounter in different laboratory using three different computers. The image obtained from the NIST were mounted in the test system using the third-party tool Arsenal Image Mounter. The image was set to read only option to prevent from the corruption of test images. The testing of the tool was done only in three different file formats each with one fragmented file inside them. In the future, the test should be carried out on over-written, fragmented, deep files etc. The test should also should be carried out on the partitions of the images, memory devices and external hard-drives. All the files recovered in the implementation were txt files and test images with pictures, audio, video and archives were not tested with disk drill. The Macintosh version of the Disk drill was not tested which should be done in the future.
