I have TI 8.0 Build 800. I use 3.5" hard drives in external USB 2.0 enclosures to store images. An odd problem I have is that the imaging process is very slow when saving to one of the external drives when using the bootable rescue CD. Specifically, imaging about 8.5G to an 80G 7200 rpm drive takes almost 2 hours; the same image written to a 60G 5400 rpm drive takes less than 25 minutes. This is using the same USB port and cable, but different enclosures.

If I create the image from within Windows XP SP2, it takes about 5.5 minutes to the 80G, and about 7.25 minutes to the 60G.

Any ideas why the process is so slow when run from the rescue CD?

Thanks,
Jack

 

You have discovered that not all USB 2 chipsets are the same. Windows has drivers that compensate for the differences, but Linux (the TI boot CD) drivers are not so sophisticated.

 

jmk94903 - To which USB chipsets are you referring? The ones on my motherboard, or the ones in the external enclosures? I'm using the same motherboard USB port and cable to each of the external enclosures.

Hello JackMangold,

Thank you for choosing Acronis Disk Backup Software.

First of all, please download and install the latest build (937) of Acronis True Image 8.0 which is available at: http://www.acronis.com/homecomputing/support/updates/

Please create new Bootable Rescue CD after installing the update, boot your PC from this CD and see if the problem still persists.

If the problem still persists with the latest build (937) of Acronis True Image 8.0 then please create Acronis Report and Linux system information (sysinfo.txt) as it is described in Acronis Help Post.

Please also do the following:

mount /devfs/floppy/0 mntdir
cat /proc/bus/usb/devices > mntdir/usb.txt

- Collect the usb.txt file from the diskette.

Please keep your "problematic" external USB hard drive\enclosure connected while creating all these files.
