I have 2 500GB MyBook Pros (FW800/FW400/USB2.0) that I've been using with SuperDuper for 2 or 3 years to backup my PowerPC Mac Mini. I've had no problems with them. Booting via FW800 works perfectly.

I've just bought a 2TB G-Tech G-Drive (eSATA/FW800/FW400/USB2.0). Only arrived yesterday, but I've already backed up my MacBook Pro and tested the backup. All good so far.

Your experience with MyBook drives is atypical, and certainly conflicts with my own experience... Perhaps they have made some recent changes.

jazzdog 04-14-2010 11:08 AM

You're right to counsel against them. Most My Book's won't be bootable on Power PC Macs, but my model is one of the rare exceptions...

"WD external hard drives that are Mac bootable and how to format them to install an operating system..."

"...The following external hard drives should be bootable on Power PC based Mac computers systems through FireWire (1394a/b):

WD My Book Premium Edition
WD My Book Pro Edition"

Thanks for that additional information!

Updates to approved EHD list?
My Maxtor FireWire 400 EHD may be dying, so I'm looking to replace it with a FireWire 800 drive. I see that Maxtor is now owned by Seagate. Are Seagate EHDs recommended? Also, any opinions on Iomega FW 800's? Thanks in advance.

I would probably suggest the LaCie d2 Quadra or 2big.

LaCie 3 TB
I recently purchased a LaCie d2 quadra 3-TB hard disk and plugged it using its FireWire 800 connector: I ran SuperDuper 2.6.2 using the standard "backup - all files" script to make it bootable (X 10.5.8), and it seemed that everything went well, but in the end the drive wasn't actually bootable… it didn't even show when pressing the option key at boot time, even though it appeared as one of the bootable candidates when viewed by the start-up disk pref-pane!
  • I tried again with the latest SuperDuper 2.6.4: same result…
  • I partitioned (GUID scheme) the drive (three 931-GB volumes) then tried to back up the system files on the first, then on the second partition: to no avail…
  • I tried the same on a 2-year old Lacie d2 quadra 1-TB : no problem!
should I conclude that this particular type of drive can't be used to boot OS X, or is there something I'm doing wrong?

dnanian 12-13-2011 12:26 PM

Try connecting it with USB instead. Does it show up at Option+boot then?

Sucess With eSata Drives Using 2.6.2
Thought I'd also share:

Have #4 (discontinued), external OWC eSata Enclosures, (No Bridges - No Frills). Each enclosure contains #2 2TB Hitachi DeskStars, and a few older Seagates. Use straight up eSATA connections thru #2 Dat Optic PCIe 4 port eSata cards. Transfer speeds vary from approx. 10,000 MiB/s to about 2,000 MiB/s, (sometimes less).

*Depending on the size of the drive, the 'All Clear Green Indicators' sometimes take a few seconds to come up. All seem to work fine.

Why so many drives?

I'm working on a WWII Documentary - multitudes of Video.

Avoid the Seagate GoFlex Slim 320 GB USB drive -

Tried this and it produced a very flawed backup.

La Cie Max drive worked well USB or Fire Wire

G-drive mobile drive via Fire Wire works flawlessly.

Moral of this story:


You will find a list of drives and brands that work.

Don't be like me - I read the manual and set up the backup properly a few years ago... jog your memory!!

Glyph and Seagate
I have two external drives, both set up the same way - two partitions, one partition for Time Machine and the other partition for SuperDuper full bootable backups for my Intel iMac.

The Seagate GoFlex 1TB came with both USB 2 and FW800 adaptors (There is an optional adaptor for USB 3) - I use the FW. I keep this one in my locker at work, and update it every couple of weeks.

For home/desktop backups I have a Glyph GT050Q 1TB which has an Oxford 924 chip and USB 2, FW400/800 as well as SATA connections. I use the FW800.

I recently tested my ability to boot from the Glyph - no problems. Need to test the GoFlex soon.

256GB Samsung SSD 840 Series
Hi All

Just updated my 15" 2010 MacBook Pro's internal drive to a 256GB Samsung SSD 840 Series

1) Firstly backed up MacBook to external 1TB Lacie Quadra fire wire drive.
(tested boot from external, excellent)

2) Mechanical install of internal SSD drive flawless.

3) Went to format SSD drive using disk utility, had an issue
where disk utility said the drive was locked and couldn't be formatted.

4) Rebooted holding down "command r" (recovery mode) went to disk utility
formatted the SSD drive from here, perfect. (must have killed something
that was having a hold over the drive that disk utility couldn't cope with
from the mounted drive).

4) Booted into external fire wire drive, backed up to internal SSD
rebooted from internal drive, excellent.
(opted not to do a fresh install of the OS as some people have recommended,
as I trust SD implicitly).

5) Initiated TRIM Support
(as this is not an Apple drive trim was not initiated automatically)

5) Daily back up's to an external drive are flawless.

hope this helps


forgot to mention, back up's all though fast used to take approx 15 minutes, now they take 8, very cool

dnanian 03-12-2013 08:08 PM

That would make sense - we're I/O bound, so faster reads and writes mean a faster backup (and vice versa).

Thanks for the report.

Hi, Dave. What are your current recommendations for EHDs? Is FireWire still preferred over USB? Are WD and Seagate still not recommended?

dnanian 05-30-2013 12:32 PM

So, new Macs don't even have firewire, so on those I'd suggest USB 3, which is both fast and cost effective. Thunderbolt is costlier by a lot, and overkill for our purposes.

For older Macs with FireWire, that's usually the best solution. I generally recommend LaCie d2 Quadra drives, which are well built, have multiple interfaces, and have good compatibility.
