When the snapshot is finally deleted, the hypervisor’s vmfs reaps the flat file. Its blocks are freed, overwritten by new VMDKs. But for a brief time after deletion, the raw sectors on the SSD still hold the MBR, the superblocks, the half-deleted spreadsheets.
The flat file becomes — a ghost haunting the physical platters until TRIM or garbage collection finally silences it. 6. The Flat File’s Soliloquy I am not a disk. I am a file that pretends to be a disk. I have no moving parts, but I have geometry. I have no memory, but I retain every byte ever written to me — until overwritten. vmdk flat file

Each will diverge. The flat file becomes — a ghost haunting
