This was caused by some bad blocks on the physical computer that was being virtualized. One guy in the vmware forum suggested to upgrade the converter to 3.0.3 and bingo that did the trick. I didn’t get to ‘pull’ it using the ESX server, instead I installed the standalone converter 3.0.3 of course on the physical machine. I see some warnings that the converter is ignoring bad blocks and the virtualization goes smoothly. So there you go



  1. I also have 3.0.3 but I am still getting the same error. My HDD do not have any bad blocks. Any ideas..?

  2. I’ve just encountered this problem myself. Upgraded to 3.0.3, no dice. However, I detached all CD ISO image drives, client CD drives, and SCSI CD/DVD drives and suddently everything’s working again.
