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

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.

Hi Ulli,

Thanks a lot for the information,

Edi
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.

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.

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.
