It looks like WinClone is the best for the PC side, but I can't tell from these posts if one can use time-machine when doing the dual backups on the same external HD that has a partition for both bootcamp and OS X.I guess my question is, how do you set up a partition, on a single external HD, to backup bootcamp and OS X, while still being able to use time-machine to do the OS X backup?Thanks. Can one set this up to use time-machine to do regular updating of the backup? Two partitions would be the minimum.

Additionally, if our software doesn’t support your camera yet, we can add support for new video and audio encodings (our 10 years of experience in data recovery software helps us to develop something new).

System requirements:
Mac: OS X 10.6 or higher (requires Intel-based Mac, PowerPC not supported!)
PC: Windows Vista / 7 / 8 / 10 or higher

Step 1: Add your camera model with a simple click here (we will update our software for your camera model as soon as possible)

Step 2: Verify that your camera model is supported by ‘reparing’ a non-broken sample file

If your camera model isn’t listed above, or the repair tool doesn’t seem to work with your movie, please first try the ‘repair’ using a non-broken (playable) sample movie of your camera to find out if the program fully supports your camera:

1. Download the video repair tool DEMO version (.zip), and extract the downloaded archive by double-clicking it in the OS X Finder (Mac) or Windows Explorer (PC).
2. Run the video repair tool by double-clicking the application ‘gs.app’ (Mac) or ‘gs.exe’ (PC).
3. Click on ‘Choose movie…’ and choose a non-broken sample (playable) movie of your camera. Using a non-broken sample movie you can verify if the program fully supports your type of camera.
4. Click on ‘Scan’ and wait until the scan finished (spinning cursor disappears).
5. Click on ‘Preview’ to check if the movie could be ‘repaired’. If your sample file doesn’t repair, please send us a link to your non-broken sample movie (e.g. using some freely available online file sharing service such as www.wetransfer.com or ask us for our FTP), so we can add support for your camera to the repair tool.

This approach ensures that there are not two issues at the same time (program does not support your model, and damaged files does not contain any data). If it properly supports your camera model, but doesn’t work on the damaged file, the damaged file is too broken for a repair.

After you sent us your sample movie, we’ll try adding support for your camera (this may take some weeks). All customer files are kept confidential.

Step 3: Your sample file repairs, but your broken movie doesn’t repair
If your sample movie correctly repairs (step 1), but your corrupt file doesn’t repair, we may check your corrupt file. Send us your corrupt movie (and one working sample movie of your camera) using an online file sharing service such as www.wetransfer.com (up to 2 GB files), www.wesendit.com (up to 5 GB files) or www.filemail.com (up to 30 GB files). After you sent us your truncated broken movie, we’ll examine it (this will take a few weeks). All customer files are kept confidential. Please only send small sample files (max. 100 MB), as we do not have a fast Internet connection here.
