Setting up new ext. hard drive

After checking the forum, I ended up purchasing an Iomega 250 GB USB/FireWire hard drive. Since this is new to me I would like to address some questions to you experts. I would like to have a clone of my Intel Imac on the hd along with storage of photos etc. In partitioning the drive, should I split down the middle or do something else? Can I mark Applications etc. on my Mac hard drive & all would copy over to new hd? I don't want to mess things up. Any suggestions will be appreciated.

Than you, Lisa

iMac, Mac OS X (10.4.6), nano 4G

In your situation, yes. The size of a clone partition should be at least 1GB more than the size of the data you will be putting onto it, and more if you intend to use the exact copy of the clone to start up your computer at some point in the future. If you will be updating the clone later, you may want to make the clone partition at least twice the size of the data currently on the hard disk.

To all who helped this beginner with the hard drive : THANK YOU !! I just finished moving the Mac hd to the clone half. I think I now have three back-ups. Niel I partitioned 80 GB for the clone as you suggested. Eric, I must say your command of the king's english when you used the word " succinctly " probably put a smile on many faces as it did to mine. Again, thanks to the forum from Texas to Italy.

Last night, I encountered a problem shutting the power off to the new hd. I had to remove power to everything. Afterward, I disconnected the line from the hd to the Mac & turned the main switch back on and then I the hd switch worked shutting the hd off. When I reconnected to the Mac it was as before i.e. could not shut the hd down. Must be something in the program. Any ideas?
Thank you, Lisa

Lisa,

I believe that you purchased an Iomega 250 GB FW/USB HD. I think I have the same or similar drive. I have an Iomega 250 GB Black Series Triple Interface HD.

The power management of this drive is a little different than you might expect and it has nothing to do with the cloning process. I have confirmed the working of this with Iomega and they assure me that it is a feature and not a bug.

The Iomega that I have cannot be powered off while connected to the Mac with Firewire. The power coming from the Mac through the FW cable keeps the blue power light on on the Iomega. If you want to power the Iomega off completely, you must first unmount the drive from the desktop (always do this before disconnecting the FW cable), then disconnect the FW cable, and then depress the power button on the Iomega (or unplug the power cord). I just depress the power button and leave the power cord plugged in. That way, the next time I use the Iomega, I just plug the FW cable into the Mac and the Iomega spins up.

I think this is a strange way of handling power on and off for the Iomega drive. As I've stated, I went through a very long series of emails and phone calls with Iomega last winter and they were unwavering in saying that this is the way it is supposed to work.

Let me know.

Regards,
Steve M.

Steve, I was half right saying "Shirt Sleeve" when I should have said "Shirt Pocket". ( Sorry about that ) Yes, I have the Iomega 250GB Black Series Triple Interface HD. The Firewire 400 was used after I purchased a cable locally. I was going to contact Iomega but since you have I guess we will have to adhere to what Doris Day long ago sang, what will be will be. This is a poor arrangement. My father doesn't like to keep changing cables because of wear & tear & this will be done almost every day if I keep the automatic update set as is.

Thank you Steve, Lisa

Steve, Shirt Pocket Support just sent this:

" Be CERTAIN to eject the drive before taking out the cable! ( as you said)
Note that I actually suggest that you leave the power on, but eject the drive. That'll let it spin down (saving the drive), and if you schedule your backups, SuperDuper will automatically mount, copy, and eject the drive for you! "

The above is their words. I'll try this tonight.

Lisa
