Hello all, I was bringing my iMac G5, 10.4.11 with latest updates, out of sleep mode with my external HD attached. My screen blinked a few times then came out of sleep mode with a dialog box saying to initialize the drive. I believe the file system(NTFS) got corrupted because this happened to me on another computer(Windows XP) about 5 years ago. I just replaced the file system & all was well. How would I go about replacing just the file system to access the files again but not erasing the drive? Is there another way that might help? I have run Onyx to see if that would fix any problems with my iMac & it did fix some problems, but now the dialog box doesn't show up anymore when I plug the external drive into the iMac & nothing appears on the desktop after an hour of waiting. I have access(company software) to Tech Tool Pro 4 & Diskwarrior 3(both up to date) for OSX Tiger, would those be of any help at this point? Am I s.o.l. with this?
