PC / MAC JPEG ISSUE

[Damian Brown]

Never had a problem with burning jpegs for clients before so this is a curious one. Without seeing the mac in question and checking out whether it has a fault, it leaves me a bit stumped.

Client received disc of jpegs. Standard hi res jpegs as every other job before, even to themselves. Same disc type, same file type. They have a mac, I use pc.

This time they said:

It's difficult to tell but it looks like about 20 I can see most of them but it took ages to load which doesn't seem right either. It says they are files it doesn't recognise?

i have received the second disc, but it is worse this time and will only load about half of the photos aaaargh! it also takes ages to do it , which is a bit weird because the mac is usually really fast. I don't know what to do.

what program are they using to open the files? Preview should be the default and should recognise anything, almost regardless of file type (in case it thinks they are not jpeg). Preview has a pretty good RAW rendering for Nikon (at least for my D90 and D40). I'd tell them to try and open the 20 'bad' images individually with preview before I put it down to file type.

Other thing to consider is what system they are running. My wife is notorious for having 10 things open (but not in use) at once and running out of memory (which slows things way down). If they are more than 90% full on hard disk space and then their RAM is used up, that would explain the speed.

Thanks,
Rick

Without stating the obvious, something is very wrong here, as macs are usually much more tolerant at opening PC saved files than vice versa. However it is relatively easy to check whether the mac is suffering an issue or the supplied disks. As you say, you have supplied jpegs on disks before to them, with no issue.... so if they can still open one of the older disks correctly, it is the new disk that has got the problem.
As to what that problem may be, I'm afraid I have no clue, sorry.

try and find out what it says under file info for what it thinks the files are and the default program on some of the affected files..

I have had a couple of similar problems, even Mac to Mac. My guess it may be having trouble just reading the disks, I tracked it down to a poor batch of DVD's. Changing to a different pod solved the problem. Try re writing from a different box of disks and see if this helps.

Do they have another Mac or PC. I've found that it's possible that whilst one drive won't read a disk another will.

yes have you started on a new batch of CD's lately have seen it before were the colour of the disc (usually blue or green) can affect how good the disc is read (although only seen it on laptop drives).
