    What is Duplex Secure's SPTD Driver?

    Thanks for your reply! Is there a different Virtual Drive program I could use instead of DAEMON Tools which would be more compatible with IMGBurn and wouldn't cause a warning?
  2. Every time I start ImgBurn v2.5.5.0 on my Windows XP Pro SP3 system, one of the first lines in the log window is "W! Duplex Secure's SPTD driver can have a detrimental effect on drive performance." I don't recognize this program name and don't think I ever installed it. ImgBurn seems to be running just fine. Why am I getting this message and what should I do about it? Here is the full transcript of what appears in the log window at startup: I 13:06:44 ImgBurn Version 2.5.5.0 started! I 13:06:44 Microsoft Windows XP Professional (5.1, Build 2600 : Service Pack 3) I 13:06:44 Total Physical Memory: 3,395,704 KB - Available: 2,470,328 KB W 13:06:44 Duplex Secure's SPTD driver can have a detrimental effect on drive performance.

FYI, Drive 3 and Drive 4 are virtual drives created by DAEMON Tools. Thanks! John

    Write Speed Miscompare

    I am using ImgBurn v2.5.2.0. When I burn an audio CD, these warning lines appear in the transcript: W 15:45:44 Write Speed Miscompare! - MODE SENSE: 1,412 KB/s (8x), GET PERFORMANCE: 8,682,906 KB/s (214.4x) W 15:45:44 Write Speed Miscompare! - MODE SENSE: 1,412 KB/s (8x), GET PERFORMANCE: 8,682,906 KB/s (214.4x) W 15:45:44 Write Speed Miscompare! - MODE SENSE: 1,412 KB/s (8x), GET PERFORMANCE: 8,682,906 KB/s (214.4x) W 15:45:44 Write Speed Miscompare! - MODE SENSE: 1,412 KB/s (8x), GET PERFORMANCE: 8,682,906 KB/s (214.4x) W 15:45:44 Write Speed Miscompare! - MODE SENSE: 1,412 KB/s (8x), GET PERFORMANCE: 8,682,906 KB/s (214.4x) W 15:45:44 Write Speed Miscompare! - Wanted: 2,117 KB/s (12x), Got: 1,412 KB/s (8x) / 8,682,906 KB/s (214.4x) I set the program to burn at 12x. This is less than the maximum speed supported by both the drive and the discs. The burn was successful, but I'd like to know why I am getting this warning and what (if anything) I should do about it. The drive is a Plextor PX-850SA. Thank you.
