A Method for Recovering Data From Failing Floppy Disk Drives

نویسنده

  • Charles Preston
چکیده

Background: This paper is about a method for recovering data from floppy disks that are failing due to weak bits. It describes a repetitive read technique that has successfully recovered data from failing floppies in forensic cases and describes other related techniques. None of these techniques are new or particularly unique, however, they are not widely published to the best of the authors knowledge and some of the related analysis may be helpful in making more definitive determinations in some cases.

Recovering Data from Failing Floppy Disks

As floppy disks and other similar media age, they may lose data due to a reduction in the retention of electromagnetic fields over time, mainly due to environmental factors. However, the coding techniques used to write data can be exploited along with the fault mechanisms themselves to successfully read data from failing floppy disks. This paper discusses the problem of recovering data from fai...

A Method for Recovering Data From Failing Floppy Disks with a Practical Example

As floppy disks and other similar media age, they have a tendency to lose data because of the reduction in retention of electromagnetic fields over time associated with various environmental degradation factors. In attempting to read these disks, the coding techniques used to write them can be exploited along with the proposed fault mechanisms to demonstrate that repetitions of read attempts un...

Solid State Drives: The Beginning of the End for Current Practice in Digital Forensic Recovery?

Digital evidence is increasingly relied upon in computer forensic examinations and legal proceedings in the modern courtroom. The primary storage technology used for digital information has remained constant over the last two decades, in the form of the magnetic disc. Consequently, investigative, forensic, and judicial procedures are well-established for magnetic disc storage devices (Carrier, ...

Dynamic characterisation of the head-media interface in hard disk drives using novel sensor systems

Hard disk drives function perfectly satisfactorily when used in a stable environment, but in certain applications they are subjected to shock and vibration. During the work reported in this thesis it has been found that when typical hard disk drives are subjected lo vibration, data transfer failure is found to be significant at frequencies between 440Hz and 700Hz, at an extreme, failing at only...
