summary

Thirty-five years of storage war stories lands on concrete fixes: using DDrescue, TestDisk and PhotoRec to recover a manuscript and a degraded RAID 5, forcing-assembling an 8–disk array to salvage 8–9 TB in hours instead of days, and switching out buggy Marvel PCIe SATA HBAs to stop DMA errors. Covers using mdadm and kernel DM to reassemble arrays, benchmarking with hdparm/fio, running erasure coding like 8+3 across 16 disks, and how plaster dust and humidity killed an entire room of drives.
