This contribution offers a reflection on the application of forensic computing techniques to authorial philology, with examples drawn from the digital archive of Franco Fortini—the first Italian case to be examined using these methods. The study is part of a broader analysis of contemporary writers’ hybrid archives, where paper and digital materials coexist, and it grapples with the complexity arising from the absence of the original hardware and the non-linear transmission of documents, which in Fortini’s case have survived thanks to three distinct backup sets from his last computer. The article documents the philological and forensic reconstruction work carried out on 115 floppy disks, based on clustering techniques, metadata analysis, hexadecimal reading, and reconstruction through emulators, in order to restore the genealogy of the digital documents and outline a plausible chronology of their revisions—thus contributing to what Thorsten Ries has termed hard drive philology.
