This is a report of events which seem to indicate that there might be a problem running CCleaner on VirtualBox fixed size virtual disks. I have two Windows 7 virtual machines running in Virtual Box on a Kubuntu host. On one of my Win7 machines (lets call it A), I have had problems when starting the virtual machine, it was checking the disk and reporting a lot of errors. I had this repeatedly until I noticed it only happened when I had run CCleaner before closing down the machine (which I usually do). On the other win7 virtual machine (lets call it , I was also running CCleaner but I had no problem. One day I could not start the A virtual machine any more and had to restore a previous version of the virtual machine disk and I completely stopped using CCleaner ! The two machines are based on the same OS (Win 7 home premium), I have installed different software, this might be the cause. Another potential cause which seems to me more likely is that the B virtual machine is built on a "dynamically allocated storage" disk whereas the A virtual machine is built on a "fixed size" disk. Recently I needed to enlarge the disk of my B virtual machine, and I cloned the disk to a dynamic size storage like the A machine. And now, I have run CCleaner a number of times and things seem to be OK (only the first time I ran CCleaner after the operation, CCleaner ended up crashing but after that everything has been clear). Cheers Jean-Marie Technical details : Kubuntu 13.10 / VirtualBox 4.3.6 / Virtual disks for A and B virtual machines are .vdi files under SATA controller

Hello, I have experienced a problem which may be related to yours I have two Windows 7 virtual machines within VirtualBox installed on a Kubuntu Host I have had problems with one of my Win 7 VM, when starting it it opened a window requiring a disk check, and it was taking a fairly long time before it fixed a lot of problems I had this happen regularly until I noticed that it happened when I had done a CCleaner cleaning before closing the VM The strange thing is that I had the problem only with one of my Windows 7 VMs and not the other one. Both had been built starting from the same Windows 7 CD, but I have different software installed (one is my machine, one is for my wife and guests !) Now perhaps a difference between the two VMs is that the one that causes the problem is made with a fixed size vdi disk, whereas the VM where I have no problem is made with a dynamically allocated size vdi di
