Need help with Disk Copy 6.3.3 !!!
I'm a Mac user but no software expert, so perhaps my problem seems to be trivial, but I really need help with it:
We have a contract with an external provider to publish Mac (classic)/Windows hybrid CDs for us. So I have to send Master-CDs (several/year) which includes specifying a checksum created with "Disk Copy 6.3.3". On my Macmini (MacOS X 10.4.2) the good old "Disk Copy" can't determine the checksum (error -19) and other applications I tried (i.e hdiutil,...) did show different checksums as "Disk Copy" on a Mac classic computer.
Can anyone tell me how to get the same checksum created by "Disk Copy" on a classic system on a Mac OS X-System ?
