vmkfstools -c <size> -a lsilogic /path/to/repaired.vmdk Then manually edit the descriptor to point to the existing -flat.vmdk file. The VMDK flat file is the raw, fixed-size storage backbone of a thick-provisioned VMware virtual disk. While invisible during normal VM operation (managed through the descriptor file), it becomes crucial for performance troubleshooting, manual recovery, and understanding VMware’s disk layout. Treat it with care — it holds all your VM’s data in its most literal form.

Here’s an informative write-up explaining what a file is, its role in VMware virtualization, and how it differs from other VMDK file types. Understanding the VMDK Flat File in VMware Virtual Machines In VMware virtualization, a virtual machine’s virtual hard disk is typically represented by a set of files. Among them, the -flat.vmdk file is one of the most critical, yet often misunderstood, components. What Is a VMDK Flat File? A VMDK flat file (e.g., vmname-flat.vmdk ) is the raw, pre-allocated data file that contains the actual binary content of a virtual disk. It is a contiguous, fixed-size file that directly stores the guest operating system, applications, and user data in a raw disk format — without any compression or sparse properties. vmdk flat
