Why is True Image 10 x Slower Making Cold Image with Boot Media?
My WinXP C Drive has 73GB on it. Running from Windows it took approx 15 mins to image the C Drive to a 2nd physical drive in the PC.
However, when I used the recovery DVD to make a cold image to the 2nd physical drive, it took over 2 hours to make the same image. I was careful NOT to select the sector by sector option, and I left the default compression algorithm unchanged. I would expect the cold imaging to be at least as fast of faster than a hot one. Can anybody tell me what's happening?
Thanks, Murray

Tuttle, thanks! I have 2 PCs which both have completely different H/W. I must have mixed the two rescue DVD's. I will try swapping the media.

If created by the same version/build of True Image, Rescue Media would be identical. Nothing on the Rescue Media is unique to the hardware that created it.

Yes, both versions of the rescue media were created with TI2013 on their respective H/W. So what do you think would account for the 10 X speed difference? Is it possible that when using a DVD as the rescue media, that TI2013 is continually accessing some of its code from the DVD instead of running fully from RAM and its the relatively slow access time of the DVD that is actually slowing the process down? Is it possible that the s/w is that dumb? Would you expect there to be a difference if the rescue media was a USB memory stick?

If you have two different PC's with different hardware it is definitely possible that one had better Linux driver support than the other. Other things that could affect the speed are the BIOS, chipset, USB ports, state of the internal data connectors, and not least RAM performance.

What we're saying is that usually there's little or no difference. Rescue Media is not slower on my system.
If your PC has some hardware that has less-than-best support in the Linux Rescue Media, that could cause it to backup more slowly. One common cause is lack of support for certain USB 3.0 controllers, such that in Rescue Media the backup would occur at USB 2.0 speeds. Again, not an issue on my PC as the Rescue Media runs my USB 3.0 ports at USB 3.0 speeds.

Thanks for all the help. I think there must be something in the motherboard h/w that is not very compatible with the drivers on the rescue media causing the cold image to be so much slower. It only happens on this one PC. My 2nd desktop and my family's 3 laptops are not affected by the speed issue. I will just modify the imaging strategy for the slow one to avoid having to do a cold image of it.

What is "a cold image"?

A cold image is one you create by booting up your PC from Rescue Media and imaging the drive containing your OS.
