How does the Solitaire Forensic? handle bad sectors on the Suspect and Target drives?

Answer

Bad (or "weak") sectors on the suspect drive are handled in the following way:

  • By default the first option is set to "Abort", the Solitaire Forensic™ will abort the capture process upon encountering the first bad sector. Note that the Solitaire Forensic™ will still make several attempts to correctly read the sector in question, but unless a perfect read was achieved, the process will abort.
  • The second option is "Skip". When this option has been selected, the Solitaire Forensic™ will still make several attempts to achieve a perfect read, but will move past the bad or weak sector instead of aborting. Note that there may be a CRC mismatch after the capture session has completed.
  • The third option is "Retry". This option instructs the Solitaire Forensic™ to spend more time attempting to read all of the data from the bad or weak sector. This option can slow down the capture process.
  • The forth option is "Recover". When selected, the Solitaire Forensic™ will use a more complex algorithm in an attempt to retrieve as much data as possible from each bad or weak sector. Although this option is very effective at recovering data from bad or weak sectors, it can be time consuming.

Bad sectors on the target drive are handled as follows:

  • If the Verify setting is disabled, the Solitaire Forensic™ will not detect bad sectors on the target drive, unless the drive returns an error. Note, however, that newer drives use automatic reallocation and will rarely exhibit a bad sector, and thus reduce the probability of a problem to a negligible amount.
  • With the Verify setting set, the Solitaire Forensic™ will perform a scan operation on each sector after data has been copied. This scan occurs in step with the capture session and is transparent to the user. If an error is detected, the Solitaire Forensic™ will make several retries and abort if unsuccessful.
