SSH into the ESXi host. Run:
| Tool | Best For | Notes | |------|----------|-------| | (bootable) | VMFS5, VMFS6 | Scans raw sectors, reconstructs -flat.vmdk | | UFS Explorer RAID Recovery | Complex storage, RAIDs | Industry standard for VMware recovery | | DiskInternals VMFS Recovery | Simple deletions | Less expensive | | Klennix VMFS Recovery | Extremely damaged/corrupt VMFS | Forensic-level | recover deleted flat vmdk file
VMFS (typically version 5, 6, or 6.81) is complex. Consumer tools won't work. You need VMware-aware recovery tools: SSH into the ESXi host
This is an excellent and technically nuanced question. Before diving into the "how," we need a critical reality check: You need VMware-aware recovery tools: This is an
lsof | grep -i "deleted" If you see your -flat.vmdk listed as (deleted) , the file is still open by a running VM. (force power off). The file will be released, and you may lose it forever unless you use advanced recovery tools (rare). Proceed to Step 2.
Shut down the ESXi host, do not touch anything, and hire a professional data recovery service that specializes in VMware VMFS (e.g., Gillware, Ontrack, Fields Data Recovery). Expect to pay $1,500–$5,000.
