The last two times I've captured video it came out in 6 clips. I have the detect scene selection checked, but I never stopped the camera while filming and there was no dropped frames. I remember reading something about this on here but couldn't find it .
Well, it must be formatted or you wouldn't be able to capture to it. In Windows explorer right-mouse-button click on it's drive letter and choose properties. There you will see either "FAT32" or "NTFS". FAT32 drives have a maximum file size of 4GB, which is about 19 minutes of either DV or HD captures. Are your captured files all about 19 minutes long?
The command to type in is convert E: /fs:ntfs where "E" is the drive letter. This will change it to NTFS without losing the data on the drive. Most people use this without any problems at all. However, if you can make a backup of what's on the drive first then it's always recommended that you do so, just in case you're the 1 in a million case where it does go bad.
Thanks guys I did the convert via the command prompt. This site is such an advantage in working through the many possible stumbles to getting everything working right.
