Does anyone have any experience using a PLI (Syquest) drive between a PC and a MAC. Using the Adaptec EZ-SCSI software I can format the drive on the PC, and read to it, write to it, etc. and everything works great. But the Mac is unable to mount it. If I format it for PC on the Mac, I can write to it etc. just fine but the PC can't read it. I remember Ana mentioning a shareware package that worked great for a PC reading a Mac disk but I can't remember if it would work for removable media, plus I have no idea of the name of it. Can anyone help out on this? I need to get a 15Mb Quicktime movie to the Mac by Monday at the latest. I'm already late. 🙁 Thanks DM

I use Transfer Pro to read/write Mac disks. However, Macs using system 7.5 should be able to read PC syquests. I've been able to do this with DOS 5 formatted disk but the Mac re fused to read a disk from 6.xx Ian.

Thanks Ian. I've been using the Adaptec SCSIFMT program to format the syquest. Should I be using DOS format instead/also?

I use the Adaptec AFDISK. It seems to make a difference what version of DOS your'e using. Ian.

Thanks Ian. I got MacSEE which is working fine with DOS 6.22. Will a DOS 5.0 format work? DM

I think it should. though I've found Mac's ability to read/write DOS Syquests to be somewhat flacky. It works with some machines but not with others. But then I've had problems using some Mac syquests on other Macs! Ian.

That will depend on what drivers you use on both your PCs and Macs. And to be more exactly, what formatting utilities and drivers do you use in your PC and what drivers are you installing on your Mac Syquests. First the PC side. Yes you are right, sometimes you won't get a Syquest formatted on a PC to read on a Mac and even another PC with a different SCSI card/driver combination. Why? Because there are hardware manufacturers that in one way or another include their own stuff on their drivers and formatting utilities. Low-level stuff, but enough to make a Syquest or any other removable (take the example of MOs) unreadable in other machines, no matter if it is a PC, a Mac or an SGI workstation. The solution: Keep with mainstream software and hardware. If you go away with some special stuff that are not 100% with the standard, chances are that you are going to get into trouble. In the Mac to Mac side it is more easy. Your problem is most probably caused by the an old driver installed on your Syquest. As you probably know, disk drivers are installed on a partition on each Mac disks (hard drives, Syquest, MOs…). If you have a driver in a cartridge that doesn't comply with current Apple SCSI Manager 4.3 specifications you could have a problem (only old drivers will cause you problems, specially with PowerMacs -updates are widely available and most probably for free). The same if you recieve a Syquest formatted with the latest drivers and you have an old copy of the system software. In both ways, the problem could easily being track down and solved. SyQuest clones manufacturers could be a source of problem too since some of them tend to add stuff of their own. Again, stay with the standard 🙂 ana /krazy images
