Commercial VMware Data Recovery Software



Sometimes when users create a new virtual machine or do some alterations on a virtual machine using virtual infrastructure client and set the memory allocation value of VM below the required memory value, the user interface of Virtual machine will display no warnings instead it will overcome some consequences. For example: • VM’s network adapters fail to restart instead of being reconfigured with a Windows VM. • VM unable to load its Operating System, it will display error “Error loading Operating system”. The section discussed below is based on solving VMware error loading Operating System error along with third party solution to extract VMDK file data out of VM’s. Solution: First make sure that memory allocation value for VM’s is not set below the minimum value as seen in the interface of the Guest OS. In the memory setting page users will see varied values for each of the following settings which depend on Guest Operating System into which VM is configured to run: 1. 'Guest OS recommended minimum' 2. 'Recommended memory' 3. 'Guest OS recommended maximum' 4. 'Maximum for best performance' Let’s understand the concept in detail: Basically what happens is each VM has VMDK descriptor file stored on Virtual disk and contains a parameter i.e. "DDB.Geometry, Sectors". ESX (Which is Enterprise Server X, enterprise server virtualization platform) in such case set a parameter of fixed value whenever creates any virtual machine. For example, the parameter of virtual disk which is larger than 2GB is set as 63. Same is applied for each virtual disk of any size. Likewise, the parameter is set as fixed value in the case if virtual machine is restored and where parameter is set as the customized value like ddb.geometry,sectors = "53". With regard to this concern the parameter is different from the original value and restored machine fails to start with error "Error leading Operating System". Manual solution: In order to solve this issue try to edit VMDK descriptor files to set the parameters of "ddb.geometry,sectors", "ddb.geometry,headers" and "ddb.geometry,clinders" to their original values. If still this issue is unresolved then the need for third party tools like VMDK recovery comes in demand. VMware Recovery – Recommended Application If the above VMware error loading Operating System still persists then surely there is problem with VMDK files whether they are corrupted or deleted accidently. To repair VMware hard drive corruption here is VMware recovery Software that helps to recover batch VMDK files that go in inaccessible mode and display error messages.
