HeatSync: Welcome to CDFreaks.
It looks like the software was trying to write 5.74GB (or 6,078,183,887 bytes) of data, which is beyond the standard size of 4.38GB DVDÂ±R media.
The error occured on 99% so it's probably at lead out while finalizing the first disc.
Multiple Disk Spanning
By default, if selected data exceeds the available empty space on the destination CD/DVD disk, GBM will write to the disk until its full then prompt the user to inset a new disk to continue backup, and so on, until the entire data has been backed up.
Users can instruct GBM to use a fixed amount of space from each inserted disk, to do so:
- From the left navigation menu in the backup wizard select Where to
- Select CD/DVD media ( DVDÂ±RW/DVDÂ±R/DVD-RAM/CD-R or CDRW)
- Select Use fixed split size
- From Size per disk, choose a value or type one directly into the box
When using a fixed user defined split size, make sure to leave some space as a safety margin for the table of contents written when closing the disc session.
You might want to try setting a safe fixed split size of 4GB (or equals to 4,096MB = 4,200,000KB).
If that doesn't helps, I would also suspect the problem came from packet writing method. You can try using the ISO9660 method (Juliet):
To switch to ISO9660 format:
1. From the toolbar click Tools, then select Global Preferences
2. Select CD/DVD settings
3. Remove the checkmark next to Use Juliet file system
Although using ISO is supported in GBM it is strongly recommended that the user uses Juliet to avoid running into file/folder naming compatibility problems.
If that also doesn't help, please safe the error log and post it here. Perhaps other members who are familiar with this software can help.
PS: I don't own the software and I was just checking the user guide.
