A month ago I purchased Acronis True Image Home 10, I created backup of 3 partitions on my 80GB Hardrive to a externel USB Hardrive. I then formatted my hardrive, and I copied the needed files of of the backup images (.tib) files from the externel USB hardrive. Today I needed to get some more files from the USB hardrive, but Acronis won't open them. It worked perfectly before. (Ive tried it on two computers now). I have 16 files bak1.tib to bak16.tib, these are all from the same backup. I have copied them to my hardrive and tried to open them, I have also tried to open them with the CD Recovery disk. First I tried to open the .tib files by opening them on Windows Explorer (like I did when I used them a month ago), the first bak1.tib-bak15.tib all said a error message: But when I open bak16.tib it opens it like it did before BUT partition C and D do not have any files in them, E does, (I need files from C(70gb)). I then tried the Acronish Trie Image Home program to open the files I selected the "Restore Data Wizard" and I tried to back ip the partition aswell as files, but with both of them it says: "W00040011: Please insert the media marked "Volume 1". Press Retry when ready or press Cancel to cancel the operation" Does anyone have any ideas on how to get this data back, it is really important I need this data.
