Hi Scott, I do have an older drive - the computer is about 3 or 4 years old now. It's a Sony VAIO and here are some specs, if it helps: OS Name Microsoft Windows XP Home Edition Version 5.1.2600 Service Pack 1 Build 2600 OS Manufacturer Microsoft Corporation System Name VAIO System Manufacturer Sony Corporation System Model PCV-RX370DS(UC) System Type X86-based PC Processor x86 Family 15 Model 0 Stepping 7 GenuineIntel ~1296 Mhz BIOS Version/Date Award Software, Inc. ACPI BIOS Revision 1002, 12/26/2000 SMBIOS Version 2.3 Total Physical Memory 384.00 MB Available Physical Memory 55.89 MB Total Virtual Memory 1.28 GB Available Virtual Memory 706.74 MB I did close down some things running in the background, but I kept Norton Internet Security and Virus Scan running. I just defragged last week, so that should be ok. I haven't tried to burn a CD in safe mode - not sure if that would work. Do you think I should get a new CD Burner? BTW, it says available physical memory 55.89 MB - how can that be if I have 384 mb ram? Thanks.

Any info much LS> appreciated. In addition to what Elaine said, it sounds like you might have an older drive. All drives on the market now have something called BURN-Proof, or something similar, which takes steps to either avoid or hide buffer under-runs. This is done by either dynamically slowing down the write speed, or by going back and restarting where it left off. You may also have too much running in the background; if you haven't already, try restarting in safe mode, to see if that helps (if it'll even work in safe mode). Also, try running DEFRAG on the hard drive(s) first; that may help a bit. --Scott.
