The ROG card that dropped out whenever the fans came up
It came in from a joiner's office in Goole: a ROG with two cards, the second one holding a year of site photographs and quotes. It had been disappearing from Windows twenty minutes into a session and coming back the next morning, which points at a controller getting too hot rather than a disk wearing out, and every reboot to check spent a little more of what was left. Here the card went onto a write-blocked port under a fan and was read in runs of a few minutes with a cool-down between them, the easy regions taken first and the slow ones left to the end. Three passes filled almost every gap the first had left. A short run of sectors never answered at all, and the report says where they fall. The three folders he had asked for were opened and looked through on the bench rather than counted off a list.
