16629,Virtual Box 5.1.18 corrupted vdi drives on Windows 10,JohnP123,,"I recently upgraded to VirtualBox 5.1.18r114002 and started a few
Virtual Box Images which just worked fine under Virtual Box 5.0.32.
However, after a restart the guest's Linux file system got corrupted.
Too many multiply claimed blocks (fsock error and device no longer found).
I also notices slower performance. HDD on the host is SATA. The guest
uses a sata (AHCI) controller as well.

After digging around, I saw that there was a similar problem in 2012, so
I decided to use the IDE Controller on the guest instead of the SATA controller.
Corruption of file system no longer occurs. Problem fixed with a work-
around but still thought this bug should be reported as I lost a few
hours getting this to work.",defect,closed,virtual disk,VirtualBox 5.1.18,worksforme,"corrupt, disk, fsck, multiply claimed block",,Linux,Windows
