Error ID: BLKCACHE_IOERR while attempting to do a Windows 10 PC Reset (failed)

[GeneS]

Hello, I am running a Win 10 VM on a Win 7 host. VirtualBox hung and could not recover. I had to kill VirtualBox, not just the VM, with Task Manager. After restart Win 10 is trying to fix itself. I had it to the "Reset PC" step where it is reinstalling the OS. I just received the following error message from VirtualBox:

An error has occurred during virtual machine execution! The error details are shown below. You may try to correct the error and resume the virtual machine execution. The I/O cache encountered an error while updating data in medium "ahci-0-0" (rc=VERR_IO_CRC). Make sure there is enough free space on the disk and that the disk is working properly. Operation can be resumed afterwards. Error ID: BLKCACHE_IOERR Severity: Non-Fatal Error

The VM has 60 GB, and the host drive (an external hdd) has over 2TB free. This has proved to be fatal; the Windows 10 VM has so far not been recoverable.

I could not get the VM to shut down gracefully, so I hope the end of the log file is still usable. I have submitted this to the forum, where I was advised to submit it here.

Thanks for your help, Gene
