Here's an odd one. I have two photographer friends on MACs, I'm on PC. Recently one burned a DVD of some TIF files, and handed it to me, and it opened perfectly. Today the other friend gave me a DVD of TIF files, and the damn thing crashed the same (new) computer that had opened the first one perfectly. When I opened Photoshop CS and tried to open the files directly from the DVD, PS went ballistic. Palettes disappeared, the mouse locked up, the whole screen froze. I had to hit Ctrl-Alt-Del to be able to close PS and regain control. I was able to use the Windows Explorer to copy the files to the harddrive, where they opened fine. The files did have TIF extensions BTW. The only thing that seemed odd was, on the second DVD, there was an extra file named ".ds_store" that my friend says is created by the DVD burner software (and I don't know the brand) whenever he burns a DVD. Of course, no else has had this problem with his DVDs. This isn't something we do a lot, but I would like to solve it so it doesn't happen when I burn DVDs for my clients.

ds_store is a mac hidden system file for displaying the folder attributes, rather like the properties in windows and is harmless.

However tiff files saved on a mac can be in mac format (byte orded) and not read on a pc. ask you friend if he saved them in mac only format or PC format.

Photoshop has a 2gb limit on image size's and this might had caused the application to go awol if you tryed to open 4.4gb in one go (unlikley)

Go here and get the demo of ISOBuster

http://www.smart-projects.net/isobuster/

You can use it to open the disk raw, and copy files manually from the disk to your hard drive bypassing certain steps the OS takes in opening the disk.

This will NOT fix the problem if it is due to the TIF files being in Mac format instead of PC....

I love ISOBuster... it has allowed me to get files off of corrupted CDs many times. It even saved data that was needed in a class action I was working on that eventually settled for $15 million. Without that data the case would have been lost.

CS does not have a 2gb limit, previous versions do however.

"(CS) version of Photoshop raises the image-size limit, from 30,000 by 30,000 pixels and 24 channels per file to 300,000 by 300,000 pixels and 56 channels per file. To accommodate such heft, Adobe has also introduced a large-image file format, PSB. However, PSB is not backward compatible with earlier versions of Photoshop."

CS rocks

I don't think the Win/MAC TIF-version is the problem. As I said, using Windows Explorer, I was able to see the file list and copy the files from the DVD to the hard drive with no problem, then open them in PS/CS with no problem. It was only when I tried to open them in PS directly from the DVD that the problem occured. The files are about 35mb.

Andy,

Ask the person what software he used to burn the disk. There are 2 likely alternatives:

1. He used the built in 'desktop" burning that Mac OSX has. (put in blank CD, It shows on desktop, drag files to disk icon, burn)

2. He used "Toast" the most popular CD authoring software on the Mac platform.

I would bet that the CD giving you the problems was burned the first way.

I work in prepress for a commercial printer, so I deal with a LOT of burned disks, and 9 times out of 10, if we have issues with a burned disk, its because some form of "desktop" burning was used, rather than a standalone Authoring Application. The problem seems to be getting worse as everyone and their dog wants to add "desktop" burning, and eliminate using an application to author the disk. From the Mac side, using "Toast" to burn disks, has NEVER resulted in a disk that caused problems for a PC, in my experience. The defualt settings for the program create very bi-platform compatable disks.

Having said that however, I make it a habit to NOT ever try to open files directly from the CD, if I can avoid it, especially Large files. I always copy them to my hard drive first. Just seems to be faster overall, and create fewer problems. (I get a lot of sales reps wanting to know "whats on this disc" all day long"
