iMac Core Duo (Early 2006) Special Report: Problems with flash memory devices

A number of users report issues with USB-based Flash memory devices and the iMac Core Duo. In many cases, these devices are inordinately slow to transfer data or stall indefinitely when connected to an Intel-based iMac.

In some cases, simply re-formatting the flash drive using the version of Disk Utility included with Mac OS X 10.4.x for Intel will resolve the issues.

MacFixIt reader Mike writes:

"In my first experience with an Intel-based Mac, I couldn't load items from the 1G SanDisk Cruzer Compact Flash drive I use for loadsets. The drive would appear on the desk top, but when I went to transfer files, it would hang halfway through, requiring a power re-set to recover. Same with both a Mac- and PC-formatted drive."

It has yet to be determined whether or not this problem relates to a potential USB power draw issue with the Core Duo processor, documented in this eWeek article.
