Create a new VMDK file with the same name as the original file, but with a .vmdk extension. You can use a text editor to create a basic VMDK file with the following contents:
Replace /path/to/flat/file with the actual path to your flat file.
Recovering a VMDK (Virtual Machine Disk) from a standalone -flat.vmdk file is a common emergency procedure for VMware administrators. In the VMware ecosystem, a virtual disk is typically split into two parts: a small ( .vmdk ) containing metadata and a large data file ( -flat.vmdk ) that contains the actual raw data.
The need to recover a VMDK from a flat file may arise due to various reasons such as:
ddb.adapterType = "lsilogic" ddb.geometry.cylinders = "xxx" ddb.geometry.heads = "xx" ddb.geometry.sectors = "xx" ddb.longContentID = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" ddb.thinProvisioned = "0" ddb.uuid = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" ddb.virtualHWVersion = "xx"
A deep post on recovering a VMDK file from a flat file!
The block size is a critical parameter in recovering the VMDK file. You can use tools like fdisk or parted to identify the block size of the original disk.
If the descriptor .vmdk is lost/deleted, you can from the -flat.vmdk file.
