Problem Description
When starting a backup operation, I receive an Error 4 almost immediately. I am using a CD-R/RW as the backup device.

If you are NOT using a CD-R/RW, this indicates a general write error.

Cause
BackupEDGE may be having trouble starting the CD-R/RW burning process.
Solution
In edgemenu:Admin:Define Resources, look at the CD-Record command. It will probably look something like:

p/cdrecord dev=XXX C

where XXX will be replaced by a device node and/or some numbers.

Go to a root prompt, and try the following:

dd if=/dev/zero bs=2k count=10000 | /usr/lib/edge/bin/cdrecord dev=XXX -

DON'T FORGET THE TRAILING '-'! If this does not successfully burn the CD-R/RW with about 20 Megabytes of zeros, then the command is in error. Try:

/usr/lib/edge/bin/cdrecord -scanbus

to see if there is a better selection of XXX than the one that was previously given. If there is such an XXX such that the above dd command works, try replacing it in Define Resources. If this device was autodetected improperly (i.e., has the wrong 'XXX') by BackupEDGE, please send email to support@microlite.com so we can correct this.

If the cdrecord command works but you are still getting the Error 4, please contact your VAR / Reseller / Dealer or Microlite Techinical Support, as appropriate.

NOTE TO ATAPI USERS: OpenServer 5.0.5 and earlier does not currently support ATAPI CD-R/RW devices. If you have OpenServer 5.0.5 you should upgrade to 5.0.7 for ATAPI Support of optical devices.
