All, Per T13/1699-D Revision 4a (from May 2007) word 217 of the identify block should be populated with a "1" to identify non-rotating media. http://www.t13.org/Documents/UploadedDocuments/docs2007/D1699r4a-ATA8-ACS.pdf Does anyone know if that is a reliable field? Specifically there are two separate issues: 1) Are all devices reporting a 1 in field 217 non-rotating? 2) Are all production non-rotating devices populating that field with a 1. Is there some other reliable mechanism for identifying a SSD? -- Greg Freemyer Head of EDD Tape Extraction and Processing team Litigation Triage Solutions Specialist http://www.linkedin.com/in/gregfreemyer CNN/TruTV Aired Forensic Imaging Demo - http://insession.blogs.cnn.com/2010/03/23/how-computer-evidence-gets-retrieved/ The Norcross Group The Intersection of Evidence & Technology http://www.norcrossgroup.com -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
