FRCP 26(f) Meet and Confer Consulting
The updated FRCP mandates that parties meet and confer to discuss potential ESI. Many judges have encouraged counsel to utilize knowledgeable technical experts to assist the collection of ESI. 

The updated rules force parties to focus on the problems of preservation and eDiscovery on the front-end (instead of potentially facing sanctions motions on the back-end) for failure to preserve and/or produce information.

D4 can help prepare for and resolve the following: 

  • Preservation practices
  • Scope of discovery
  • Accessibility of ESI
  • Production of metadata
  • Costs & burden to produce ESI
  • Forms of production
  • Privilege issues and waiver
  • Variations from FRCP and local rules
  • Inventory of IT infrastructure (Data Map)

Cell Phone Collection

Extraction and review of ESI from mobile devices is quickly becoming standard practice in eDiscovery. Evidence that can be potentially collected from a mobile device may come from several different sources, including a SIM card, handset and/or attached memory cards.

Traditionally, mobile device forensics was limited to the recovery of text messages, call logs, contact lists and phone IMEI/ESN information. Newer generations of smart phones also include web browsing, wireless network settings, e-mail and media information.

D4 can acquire and analyze most ESI found on mobile devices including:

  • E-mails
  • Contacts
