Ghost 2003 at USB 2.0 speed

Hi,

Need help to configure either Ghost 2003 or the IDE hard
disk enclosure.

Hardware:
Shuttle PC XPC-SB51G (with USB2.0 enabled in BIOS)
DTK IDE Enclosure (http://www.dtk.com.tw/product/enclosure/den351.html)
USB 2.0 cable (as provided by the Enclosure, it's labelled USB 2.0)

Software:
Ghost 2003 (updated to build 789)

When I use Ghost 2003 to clone my hard disk, it is running
at 85MB/min (almost the USB 1.1 throughput speed of 12Mbps
or simply 90MB/min). In Ghost 2003, I've also selected to
load USB 2.0 drivers before the cloning process begins.

How can I configure either Ghost 2003 or the Enclosure to clone
the hard disk at the maximum speed of USB 2.0? That is, to clone
at the speed of 480Mbps (= 3600MB/min)?

Thanks for any advice.


Regards,
Sean

You will never, ever see that speed.

Around 1000MB/min is a more reasonable expectation for a Ghost clone
over USB2. What kind of performance are you seeing when your OS is
running? (Either run a benchmark, or copy a large file and time it)

May I know why is that so?

I can copy an approximately 700MB file over within 35 secs, that works
out to be 1200MB/min. That's reasonable enough compared to the 85MB/min
speed for Ghost 2003. Any idea/suggestion how I can up the performance
in Ghost 2003? (At 85MB/min, I can never able to clone my 40G HDD within
a reasonable period of time). Please help, thanks.

Basically because you dont get any like 3.6GB/min even with
the best arrangement, two IDE drives on different ribbon cables.

There's much more protocol overhead with USB2.
 
Ok, understood the part on overhead.

But then, any idea why Ghost 2003 is running at a (somewhat)
USB 1.1 speed instead of (somewhat) a USB 2.0 speed? Thanks.


Sean.
 
What sustained transfer rates can one expect off the platters?

Actual rates would be lower because of file fragmentation etc..

Presumably the driver used for USB ops is having
a brain fart and is only use 1.1 for some reason.

Clearly the hardware and Win level ops are
fine with that thruput you got with file copy test.

Get the latest version of the dos driver for usb from Symantec.
 
May I know what am I suppose to do with the DOS driver?
How do I start up the cloning process after the DOS driver
has been loaded? Thanks.

Depends on how you are running ghost.


Same answer.

I thought Ghost will ALWAYS run in a DOS boot. The DOS boot can be either
through a boot diskette or by invoking the Ghost GUI which restarts the PC
to actually run Ghost in DOS mode.

There was a Liveupdate many months ago that updated the USB drivers in
Ghost. Worth a try.

Sure, but its how you do that that affects which driver used.

And with that approach, its easier to be sure
which version of the driver is being used.

And its a bit harder for someone who isnt particularly fluent to
work out which dos driver is being used in that particular situation.

Thats what I said originally in different words.

Hi, I followed the instructions in Document ID 2003011609192825
(Titled "Cannot create or restore an image using an external Maxtor
USB or Firewire hard drive with Norton Ghost 2003") and updated my
system as instructed.

When Ghost 2003 reboots to start the cloning process, my system
stopped at the line "Finding a drive letter for your Iomega drive"
(it merely just stop running, and it is not hanged as I can still
Ctl-Alt-Del to reboot).

Any idea what's happening? Thanks.

Disconnect all USB hubs and other USB devices when Ghost runs (reboots to
DOS).

In my work PC, I have to do that for the boot process to proceed beyond that
point.

At home, I have 6 USB devices attached to my PC, but no USB hub and the
bootup proceeds.

So, as a troubleshooting step, try disconnecting USB devices other than your
external hard drive..

As suggested, I disconnect all other USB devices and connect the
enclosure directly to the USB port. Still no luck. :(
