How to confirm that the data is being properly written to the tape media


To confirm that data is being properly written to the tape media, perform the following steps:

1. On the Devices tab, right-click on the name of the tape drive, and then select Properties.

2. Click on the Statistics tab (Figure 1)

Figure 1

The procedure given above shows drive error statistics for the tape device. The statistics can be viewed per tape. If only certain tape media have errors, then the problem may be with the tape itself. If each tape has a similar amount of errors, even when using new tape media, this usually indicates a problem with the way the tape device is writing to the media.

To view statistics on each tape cartridge, perform the following steps:

1. On the Media tab, under User Media Sets, click on one of the media sets until tape cartridges appear in the right pane.

2. Right-click on the cartridge in the right pane, select Properties, and then click the Statistics tab (Figure 2).

Soft write errors are recoverable write errors, which indicate that there is a problem with the way data is being written to the tape. Hard write errors indicate that there may be data loss when data is written to the tape. Listed below are the reasons why Soft write errors and Hard write errors occur:

1. Outdated SCSI controller drivers

2. Outdated tape drive firmware or device drivers

3. The SCSI Bus Speed is set to high for the tape device

4. The tape device needs to be cleaned

5. The tape device has been replaced and has not been properly redetected by Backup Exec

6. The tape media has been used beyond the tape manufacturer's recommended retirement specifications

7. The tape media is incompatible with the current tape device

8. The Preferred configuration of the device is not set properly (Figure 3)
