Floppy disks have an unknown shelf-life. Estimates range from 10-30 years. The disks are known to deteriorate over time, which makes retrieval of their contents difficult or impossible. The <a href=\"http:\/\/www.softpres.org\">Software Preservation Society<\/a> (makers of <a href=\"http:\/\/www.softpres.org\/glossary:KryoFlux\">Kryoflux<\/a>) report that \u201cOur practical findings show that disks from 1985 are frequently found \u201crotten\u201d, and thus we would estimate around the 20-year mark is about right for 3.5\u201d DD floppy disks\u201d. CDs are also a new storage media, whose longevity is unknown. Gilbert suggests that the early long lifespan claimed by manufacturers of compact discs should be viewed with \u201cat least a little scepticism\u201d.<\/p>\n<p>The project aims to audit the South Australiana computer disk collection, to trial available tools for making disk images of selected parts of the collection, as well as to develop strategies to enhance discoverability of the items.\u00a0 As significant amount of Australia\u2019s digital heritage is thought to be in the hands of private collectors, the project is further trialing innovative collaborative relationships with expert informants, and private collectors to investigate how computer disk materials that are scattered in various libraries and\/or held by private collectors might be made available in the future for public benefit and access.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Convenors of the Digital Heritage research group, Denise de Vries and Melanie Swalwell, recently commenced a pilot research project with the State Library of South Australia, [&hellip;]<\/p>\n","protected":false},"author":103,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[3,4,5,6,7,8],"class_list":["post-26","post","type-post","status-publish","format-standard","hentry","category-uncategorized","tag-ahsd","tag-cd-rom","tag-computer-disk","tag-disk-image","tag-preservation","tag-slsa"],"post_mailing_queue_ids":[],"_links":{"self":[{"href":"https:\/\/blogs.flinders.edu.au\/digital-heritage\/wp-json\/wp\/v2\/posts\/26","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blogs.flinders.edu.au\/digital-heritage\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blogs.flinders.edu.au\/digital-heritage\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blogs.flinders.edu.au\/digital-heritage\/wp-json\/wp\/v2\/users\/103"}],"replies":[{"embeddable":true,"href":"https:\/\/blogs.flinders.edu.au\/digital-heritage\/wp-json\/wp\/v2\/comments?post=26"}],"version-history":[{"count":0,"href":"https:\/\/blogs.flinders.edu.au\/digital-heritage\/wp-json\/wp\/v2\/posts\/26\/revisions"}],"wp:attachment":[{"href":"https:\/\/blogs.flinders.edu.au\/digital-heritage\/wp-json\/wp\/v2\/media?parent=26"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blogs.flinders.edu.au\/digital-heritage\/wp-json\/wp\/v2\/categories?post=26"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blogs.flinders.edu.au\/digital-heritage\/wp-json\/wp\/v2\/tags?post=26"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
