My Answer: NO, no, no, no, and yes. Ok, so here is the thing. FAT32 implies that the maximum disk size is 32 GB. But this limit is debatable, for most hard drives encoded in FAT 32 are fare larger than 32 GB. NOW WHAT IS CERTAIN is that you have create an single file in it's unopened, undeditable, unviewable stage larger than 4GB on a FAT 32 system. This means that one video, compressed as a .mov, .avi, .wmv, .mp4, etc, are all excluded from this hard drive if they are over 4 GB. I have heard that you can span the documents over infinite chucks of 4 GB, but you need software or you need to know what in the hell you are doing. This "slitting" is similar to combining 2 hard drives to create one big virtual hard drive. Original Answer from someone else: Yes, NTFS and FAT32 are data formats. The system does not care what format the data is stored in. So data on an NTFS drive is simply read off the drive and written to the target drive in the target drive's format.
backup
If you rewrite your backup files. Then, yes your backup files will be rewrited (they might be the same or they can be different). The best way is to backup your files in another folder. If you are using standard window backup procedure your source files are safe because the windows backup utility just copies your files, but doesn't remove them. If you are using utility which wasn't a standard part of windows then you have to check settings very carefully. Some backup utilities do remove files instead of coping them.
Reformat the drive. If you're running Vista you need to format it as NTFS or backup will fail, that drive comes formatted in Fat32.
You flash drive has FAT32 file system. FAT32 doens't support so big files. Try to format your flash drive in NTFS and everything will work. Also you might not have enough free disk space on your flash drive.
Do you have backup software installed that is mapped to an external hard drive? The software might be automatically trying to backup your files, but the external hard drive is not plugged in.
Backup files should be kept in a different location [CD, thumb drive, external drive] in case your computer breaks down. If the hard drive fails or the operating system crashes, you have your files safe somewhere.
FAT32 does not support compression of filesor folders
No, when using the Norton 360 backup, files on the external HDD will not be deleted.
If you store your backup of your C:\ drive (which is usually where all your files, photos, etc are stored) on another (logical) partition on the same physical drive (C:\) and this is where you store your backup, if the drive should fail you would lose both the original files AND the backup as well. This is because they both reside on the SAME physical drive. Buy an inexpensive thumb drive or external hard drive and store your backups there. This way is the C:\ drive fails, you still have your backup files (on the external or flash (thumb) drive).
Connect an external hard drive to your computer and copy over important files.
The most important thing to do would be to back up all your files to an external drive or some other safe location. *The answer is: "Create a complete system backup".
The files stored on the external HDD will not be deleted when using the Norton 360 backup.
