This is a problem which first surfaced My VMware Fusion successfully boots Windows 10 on my Mac Pro, but at some point after I start working in Windows, I get a popup which contains the following error message:
Operation on file failed. If the file resides on a remote file system, please make sure your network connection and the server where this disk resides are functioning properly.
Retrying the operation just produces the error again, as does the Continue option. The Cancel option then crashes the virtual machine.
The error always names the same 'slice' of my sparse drive, which is split into multiple files but the disk space is not pre-allocated. I have used the vmware-vdiskmanager to check the base vmdk file, and its -e option initially reported that the disk chain is not consistent and the virtual disk needs repair. I then used the -R option to repair the disk, and get the message saying it was successfully repaired. However, if I then go back into Windows, the same error happens.
If I try to copy the VM to another drive, I get an "error code -36" from MacOS. I have tried the dot_clean utility, but this doesn't resolve the problem, and my VM is on an AFPS volume, which means that even if I was prepared to pay the UK prices for DiskWarrior, it wouldn't be able to fix the problem.
Can anyone suggest another remedy for this?
Additional information: I don't have to do anything in Windows to make this problem manifest itself. Just leaving the login screen on for a few minutes will eventually result in the popup appearing.
