2.12. TC-05-EnCase6 Helix3 Pro R3 (Release Date: 30 th , Dec 2009) Test Case TC-05-EnCase 6 (Helix3 Pro 2009 R3) Test & Case Summary: TC-05 Acquire a digital source to an image file in an alternate supported format Notes: Convert images from test002 Hard drive to Encase 6 format to see whether helix can output other type of images except dd. Assertion: AFR-01 The tool accesses the digital source with a supported access interface AFR-02 The tool acquires a digital source AFR-03 The tool operates in an execution environment AFR-04 The tool creates an image file of the digital source AFR-05 The tool acquires all the visible data sectors from the digital source AFR-07 All data sectors acquired from the digital source are acquired accurately. AIC-01 The data represented by an image file is the same as the data acquired by the tool. AIC-02 The tool creates an image file according to the file format the user specified. ALOG-01 If the tool logs any information regarding to the acquisition, the information is accurately logged in the log file. ALOG-02 The tool display correct information about the acquisition to the user. ALOG-03 The tool display correct information regarding to the acquisition to the user and the information displayed is Source Device: Drive Setup: consistent with the log file if the log file function is supported Drive Model: ST380811 AS (80GB) Serial Number: 6PS2CA4Z Sector count: 156,296,385 Write blocker: Tableau Forensic SATA/IDE Bridge IEEE 1394 SBP2 Device /dev/sdc: current max LBA: 156,296,385 /dev/sdc: native max LBA: 156,296,385 /dev/sdc: physical max LBA: 156,296,385 /dev/sdc: HPA not set /dev/sdc: DCO not set 230
