Most likely, you've formatted the drive as a FAT32 volume. It can't store files larger than 2 GB.
If this is not the case, please let us know an we'll continue solving this problem.
OK, so two notes from me:
1. Actually FAT32 can recognize files up to 4GB
, according the Microsoft website
2. I used the actual R Drive utility to create the boot drive, and when I boot off this device to create a backup, the bootable version of RDrive has automatically selected "Automatic" for the splitting of volume sizes, so I can only assume this is a problem of sorts with the program either determining or subsequently reading the correct file size (4 gb each).
Can someone else try this simple process?
1. Use the installed version of Rdrive to create a bootable flash drive. It should be formatted in FAT32 and be at least 8 gb in size for this test
2. Boot off the device, and hopefully select a target that is at least 6 gb in size so that it automatically splits the backup volumes
3. Ensure in the options that "Automatic" is pre-selected by RDrive for the split file sizes
4. Once backup is complete, use the included "Check integrity of backup" on the backup you just created...it should return an error similar to mine...
If this is the case, then someone should look at the exact file size RDrive is using when "Automatic" is used, and maybe reduce it?
