Exam 312-49 topic 1 question 6 discussion

Let's analyze the options carefully, considering the format typically used by forensic tools like DriveSpy: The format generally is: <drive_number>:<starting_sector>, <number_of_sectors> <disk> is the disk index (0 for the primary disk), <start_sector> is the starting sector number, <number_of_sectors> is the number of sectors to copy. Let's look at the options: A. 0:1000, 150 → starts at sector 1000, or the starting sector must be 1709, so no. B. 0:1709, 150 → disk 0 (primary), sector 1709, 150 sectors → match perfectly. C. 1:1709, 150 → disk 1 (not the primary disk), so no. D. 0:1709-1858 → range notation, but the expected format seems to be a comma and number, not a dash. Correct answer: B. 0:1709, 150

To copy 150 sectors starting at sector 1709 on the primary hard drive using DriveSpy, you would use the following command: drivespy dd if=/dev/sda of=image.dd bs=512 skip=1709 count=150 The key parts of this command are: if=/dev/sda - This specifies the input file (if) as /dev/sda, which is the primary hard drive. of=image.dd - This specifies the output file (of) as image.dd, which will contain the copied sectors. bs=512 - This sets the block size (bs) to 512 bytes, which is the standard sector size. skip=1709 - This skips (doesn't copy) the first 1709 sectors. count=150 - This copies 150 sectors after skipping the first 1709. So in total, this will copy sectors 1709 through 1858 from the primary hard drive /dev/sda into the file image.dd.
