Hi, I'm thinking of buying ATI 10.0 but have a couple of questions before I do so. (Yes, I did look at the 92 page PDF but, as I've no experience of backing up the entire C:\ partition before, I wasn't too sure that I understood what it was saying). Also, manuals don't tend to say what they can't do and what problems you might encounter! The system I bought (3 years ago) is one of the standard home PCs where the single IDE drive is split into 2 partitions. Partition 0 is a hidden 'recovery' partition of about 2.4G and partition 1 is the main, bootable partition (about 74G) which contains C:\. Luckily, I've never had to use the recovery CD to restore the system. Everything I've installed from day one has gone onto the C: drive. I now want to install a second IDE drive of about 500G to act as: 1. A backup for the entire C: drive (weekly/monthly). 2. Separate data backups during the week of 'Documents and Settings' etc. 3. Standard additional storage for MPEGs files from my PVR. All my software was installed on the C: drive so all their data files are there also. I've got some services which run all the time and update various files (which they tend to hold open exclusively) on the C: drive. Their triggers come randomly from the internet so I don't want to close these services down unless I absolutely must. My questions are: 1. Can I use ATI 10.0 to backup my C: drive while Windows XP is still running? Obviously, I would stop most applications but there are a few services that I do not want to stop unless I have to. If ATI 10.0 is doing a backup of my C: drive and services are potentially updating various data files (which are interdependent) can I end up with corrupt files if I do a system restore? 2. When backing up the C: drive can I get ATI 10.0 to close programs if they are running or do I have to do that myself? If I must close down services to avoid the above problem does ATI 10.0 do this for me automatically or do I have to do it myself? 3. If my hard disk crashes and I need to replace it with a larger disk, do I need to partition it with the exact same sizes as the original disk or will ATI 10.0 do this automatically? Thanks in advance for any help you may provide. CM.
