I have an external hard drive that wouldn't mount to my 27" iMac. I finally got it to mount but through USB 2.0 (normally through FireWire800). Once it mounted, my goal was to go into the iPhoto "masters" folder to back up all my original photos since this drive is on the fritz and you guessed it, I didn't have a back up of my files.


I have approximately 51,000 items to back up consisting of about 191 GB of photos. It took about 6 hours to "prepare to copy" to the target drive (my internal HDD). Now once it finished preparing, I was shocked at the estimate of "x.xx GB of 191 GB - About 30 days" in the status window. That has now settled to show a consistent 24 days to complete. It is copying at a very slow rate. My guess is that it is the external drive because my iMac runs perfectly, and it's not sluggish when running Safari and surfing around. Although, I've ceased all other apps during this process.


As far as I can tell, the process is moving along albeit very very slowly. I can see on the target drive the files are copying over. My question is: Will this long process be harmful to my iMac? As far as I can tell, the slowness is related to the external drive. When the iMac goes to sleep, the copy process continues. I'm very hesitant to stop the copy process and plug in my FireWire800 for fear that the drive will not mount.


Any feedback or suggestions are welcomed.
