I bought Acronis v9 in October 2005 and my backup regime has been to do complete disk clones around once a month. This has worked perfectly for 11 months. I went to clone at the weekend and it fails with an "Operation Cancelled" error message just after the "Locking Partition C" message appears. PC then reboots but fails to boot up and I end up cycling the power after a minute or two. I downloaded the latest version, 3677, and get the same result. I've read some similar threads and so downloaded the latest drivers and first tried with logging disabled, same results, and then enabled logging, with the same results, too... log file attached, touch wood. I've installed nothing new in the month since my last successful clone. PC is an AMD X2/4400 running WinXP Pro. I have Norton SystemWorks 2005 installed but have done since the PC was built. Only other software of note is Microsoft Windows Defender. WinXP, Defender and SystemWorks are all set to auto-update and so are, presumably, running current versions. Help! I currently have no backup so am looking for a quick solution to this problem or will have to find new backup software!
