2.14. TC-07-InsufficientSpace & TC-08 Helix3 Pro R3 (Release Date: 30 th , Dec 2009) Test Case TC-07-Insufficient space & TC-08 (Helix3 Pro 2009 R3) Test & Case Summary: Attempt to create an image file where destination device has insufficient space, and see whether the tool notifies the user and offer another destination device to continue 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-04 The tool reports to the user if insufficient space in the destination device during the image creation process. AIC-05 If multi-file image creation and the image file size is selected, the tool creates a multi-file image except that one file may be smaller AIC-10 The tool reports to the user if insufficient space in the destination device to contain the multi-image file creation and if destination device switching function is supported, the image is continue on the selected destination device. 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 consistent with the log file if the log file function is supported Source Device: Drive Setup: Partition Table: 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 Device Start End #sectors System /dev/sdc1 63 4192964 4192902 NTFS /dev/sdc2 4193028 6297479 2104452 FAT32 /dev/sdc3 6297543 10490444 4192902 FAT16 /dev/sdc4 10490508 12594959 2104452 Ext2 /dev/sdc5 12595023 14699474 2104452 Ext3 /deb/sdc6 18892503 19149479 256977 Swap unallocated 19149480 156296384 137146905 Empty 234
