I have both Acronis True Image 8.0 and Acronis Disk Director Suite 9.0 installed on my Win98SE 1.4GHz Celeron powered system, with one WD1200 HD online. Three days ago, when I (logically) connected to my BellSouth DSL line, I noticed a great deal of unusual data flow to/from my computer, before I had clicked on the icon to actually connect to the ISP/homepage. And my disk activity light showed continuous activity. That was too unusual, so I reached down and disconnected my computer from the DSL modem. I then did a normal shutdown of the computer and then tried to bring it back up (cold boot) on the Win98SE system that I had set for default. It was the same OS that was being used when I started to get onto the internet (above). The system would not boot up on that version, so I used Acronis OS Selector to boot on the backup Win98SE OS. That version booted up OK. As I figured that I had been hit by a virus (in spite of having a current updated version of Norton Anti-Virus and Norton Internet Security installed and active).... I started backing up my data files to CD-R (using Nero), getting ready to employ True Image 8.0 build 796 (full uninstall/reinstall; what a pain!), to do an image backup to the of the 29.5GB C: partition to the 29.5GB D: partition of the WD1200 HD. I had purposefully only partioned 60GB on the WD1200 HD, and left the remaining 60GB unused, so that I could later try to clone the WD1200 to a spare WD600 that I keep off line... but that is another story. Had no problems with Nero in copying the data directories and files to CD-Rs. But when I tried to use Acronis True Image to put .tib files of the C: partition onto the D: partition, I got the following message: "E0007000F: Some of the selected partitions have the following error: Invalid File Size" So I rebooted to DOS command, and ran Scandisk on both the C: and D: partitions, running all tests except the full surface scan. No problems reported by Scandisk. So I rebooted, using OS Selector, to the working version of Win98SE and tried again to use True Image to put an image of the C: partition (21GB of 29.5GB being used) to the D: partition, and once again got the "E0007000F..." error message. Using, OS Selector, I deleted the old Win98 version that was apparently damaged by the virus. Then I copied the backup Win98SE OS so that I would, once again, have two versions of Win98SE on C: I tried booting the new copy, using OS Selector, and it worked fine. But still can't get True Image to put .tib image files of C: partition onto the D: partition. I still get the "E0007000F..." message. And Scandisk still does NOT report any errors on the C: or D: partitions. I have not done a full surface scan of the WD1200 as it will take a long time, and I don't think that there is any problem there anyway. Since I can't even get True Image to image the C: partition to .tib files on the D: partition, I have not yet tried to put either of my offline backup HDs online to try to clone the WD1200 (I have two offline backup HDs, a WD600 and a WD1200). I don't want to chance having True Image screw one of them up. I have a number of programs installed, and do NOT want to chance having to find all the old source CDs and re-install them, so I do not want to lose any of my "grandfather-father-son" HDs. I have spent over 2 hours searching through your FAQs and through this forum, and used Google to search for "E0007000F: Some of the selected partitions have the following error: Invalid File Size", with no success. How can I find what the actual problem is that True Image is reporting with the "E0007000F..(Invalid File Size)" error message... when Win98SE's Scandisk says there is no problem? And how can I correct it? Thanks.
