I bought an iMac 3.02Gb on Feb 28 to replace my 8 year-old PC, everything worked perfectly on Saturday. I plugged in a WD external hard drive (formatted NTFS) from my other laptop and transferred all the photos to the Mac. I could view them. I switched off the Mac in the evening and unplugged the external hard drive. On Sunday 6pm, I switched on the Mac, there was a flashing folder (Application) with a question mark. I followed instructions to reinstall Mac OS10.6, but I could not see the HD. Fortunately, the shop exchanged one for me on Monday. I'm wondering if I had done anything wrong or the original hard drive was already faulty. I only learned afterwards that I should drag the external hard drive to the bin before I unplug the usb.
As a result, I'm a bit scared to touch anything at all at the moment.
