Well, I've managed to copy a load of files off another drive with no issues so thought all was fine. I have a camera I use on my bicycle to record my journeys to/from work and I hadn't used it since getting the Mac for various reasons. I used it today and when I got home, tried to view the data. The camera uses a micro SD card to store data and has a mini-USB socket so I plugged it into the Mac and a drive appeared and I could see the AVI files (they even thumbnails). They wouldn't play in QuickTime at all via the connected USB cable (black screen, no sound) and when I tried to copy them to the Mac desktop, they failed with various weird error messages.
I used boot camp to reboot to Windows 7 on the Mac and they played fine on the PC though seemed to stop randomly part of the way through on occasions. This never happened on my 5 year old PC (core 2 quad core Intel but an older model) but a brand new Mac mini i5 with 8Gb memory can't play?
I copied the files to the Windows 7 desktop, ran the disk check and repair utilities against the memory card before copying via the cable (no errors).
When I rebooted back to OS X, I could play the files perfectly from the NTFS formatted disc.
World's most advanced operating system? Lacking basic functionality more like!
The other thing that really annoys me aout the Mac is my Logitech fusion webcam works perfectly on the Mac mini in Windows 7, great images but when I reboot to OS X it's like I'm in a dark room using a candle for illumination, Bring your own accessories - as long as you've paid 40% more for the Mac approved version.
Roll on Mountain Lion if it fixes this mismash of an operationg system.
Sorry for the rant but copying files is basic....
