    IDE Hard Drives

    ldb88 Novice

      I have VMWare Workstation 5.0.0 and I cannot change my virtual hard drive off of SCSI and onto IDE because there is no IDE option.  There is one for the CD-ROM drive, however.  How do I change it to IDE?  I tried changing the .vmx file, but it said it was created using SCSI geometries and it cannot be used as an IDE.  I am willing to create a new virtual machine if necessary.

          I've seen that ide->scsi is possible ( http://www.sanbarrow.com/ide2scsi.html )but scsi->ide is more tricky. You should probably create a new ide virtual disk and then clone (with ghost as example) the scsi partition onto it.

          For creating a new VM with IDE disks you've to choose custom and after some steps you'll be asked for a virtual disk type. There you can select SCSI or IDE.

            SCSI to IDE is very easy when the disk is larger than 8GB

            simply use


            ddb.adapterType = "ide"

            ddb.geometry.sectors = "63"

            ddb.geometry.heads = "16"

            ddb.geometry.cylinders = "16383"


            for disk-geometrie.


            Don't forget that you need to fix guest-drivers if this is a systemboot-disk.

              Hi Ulli,


              why it has to be greater then 8Gb? Why this limitation?


              Thanks a lot for the information,

                It's not a limitation... it's that the geometry tables change below 8Gb; so you'd need to know the tables and/or formulae.  At that point, it's much easier to just create a new disk of the type/size you want and throw away all except the descriptor-file, which will contain the values you will need.
