IBM 73P3315 manual You cannot create a multisession disc, You cannot eject a CD or DVD disc

You cannot create a multisession disc.

Be sure that there is enough space left on the disc for another session. Writing a session requires lead-in and lead-out space (about 15 MB) in addition to the data that is recorded.

You cannot successfully write to a CD-R, CD-RW, DVD-R, DVD-RW, DVD+R, DVD+RW, or DVD-RAM disc.

Take the following actions:

1.Verify that the process is not being interrupted by a screen saver, an antivirus program, an Internet or e-mail program, or other software. Disable the functions that might interrupt the write operation.

2.Verify that the hard disk has been defragmented.

3.Consult the hard disk drive manufacturer or vendor if an older hard disk drive is conducting a thermal recalibration during a write operation.

4.Replace the disc if it is bad or scratched.

5.Disable the Windows Auto Insert Notify function on your CD-ROM and CD-RW drives.

You cannot eject a CD or DVD disc.

Take the following actions after ensuring that the drive is not in the process of writing to a disc:

1.Eject the disc through software.

2.Use the Eject button.

3.Turn off the computer. Wait 45 seconds; then turn on the computer and try using the Eject button again.

4.If other methods do not work, use the manual-eject hole, using instructions given in “Manually ejecting a disc” on page 2-4.

You cannot read from the CD or DVD disc after successfully writing to it.

Take the following actions:

1.If you can read the CD or DVD Disc in another CD or DVD player or you can see previous sessions, the directory information might be damaged on the volume, making it unreadable. To get ideas for troubleshooting, check the documentation that comes with the software.

2.You might have a damaged CD-R, CD-RW, DVD-R, DVD-RW, DVD+R, DVD+RW, or DVD-RAM disc. Try a new disc or another brand of CD or DVD disc.

3.If you can read from a CD-RW, DVD-RW, DVD+RW, or DVD-RAM disc in the writing drive, but not in another MR drive, be sure that a UDF Reader program is installed in the computer.

4.Avoid writing at the slower 1X speed unless required by your computer.
