I've been playing with an external enclosure with a 300 gig sata drive ICY BOX 3.5 SATA - USB & SATA IB-360STUS-B-BL Using my old p4 machine Acronis makes a system image in about 4 minutes and restores in 10 Using a Samsung laptop Acronus makes a system image in about 6 minutes and takes i hour 20 mins to restore. Obviously it is much quicker to copy the image to a partition and then restore. I have no practical worries here - this is only one of a number of external drives BUT this is the only one to takes so long with the laptop Question - whta is the cause of this problem ? Is it down to drivers ? igf so why is it ok with one machine and not another. any thoughts ?
