I've tried to turn on my Ubuntu VM this morning and encountered this Disk error while paging.
Had a feeling that I've seen this error before, did some Google search and encountered some suggestions.
One suggestion from VMWare forum was to check disk for corruption. I tried running chkdsk but it was too long and I wasn't 100% confident that this will solve the problem.
Found a suggestion for renaming the vmem file (this file contains the RAM data of the VM). And so I did rename this file and restart the VM. I was then presented with option to discard the state, I chose yes and the VM rebooted successfully. I lose the suspended state but I don't really care about that as long as my VM is in working order again.
