That's pretty impressive. Not only did they image the disk, it was a disk that had had a head crash and one damaged head which they managed to restore to functioning well enough to capture the data.
Now of course the big question: what is on that disk?
- danbee 15y agoI believe the head crash occurred on a different disk pack, one that they were using to test it.
- Maci 15y agoFrom the Paper: Unfortunately, within 30 seconds of the heads being loaded a high-pitched whining noise began to be emitted from the drive, implying a potential head-to-disk contact was taking place. The drive was then powered down and the disk pack and heads were carefully examined. Thorough examination revealed that Head #4 on the drive (which reads the bottom surface of the lowest data platter) had 'crashed' into the disk surface and scraped away a concentric ring of oxide material, permanently damaging the platter. This is a good time to point out the advantages of not experimenting with your primary source material when performing digital archeology experiments!
