CDROM drive questions

Ok this is for a friend of mine...

He is having issues with buring a CD from his burner connected to his labtop being readible by his home computer at home.

I have seen that even the drives at work can't read the CD that was burned by the CD burner from his lab top. but his lab to has no problem reading the copy made by the writer connected to the LT...

What should I tell him to look for, change, or why its happening.

Also, he has a Dell, he just installed a Dell DVD drive, samsung I beleive, and he did a test where he told me the results. Tell me if they sound right to you?

He siad that he burned a CD to CD using 2 different methods.
Fisrt he bruned it using the read to HD before it burned to the CD then he tried copy on the fly cd to cd with out going to the HD...

He swears that the faster burn was going from the DVD reader to the HD then from the HD to the CD writer...

He said that the total burn time was just over 3 min going to the Hd while the total burn time going CD to CD was over 5 minutes...

Does that make sence? I sure dosen't to me... If that is right then please tell me why, or if it not then let me know what I need to tell him to do so that he can fix it...

Thanks,
"g"

    Oh and he wants to know if there is a program that he can use to see if a CD that was burned is ok, like scandisk for a HD.

    I've found that if I burn CD's at too high a speed (>16x) with the ****ty CD media that I use, it can't be read in some CD-ROM's and DVD-ROM's (like my Sony 52x CD-ROM and Asus 8x DVD-ROM).

    Slowing the burn process down on my LiteOn 42x12x48 to 16x and burning on the media takes a couple extra minutes, but the disc can then be read on any CD/DVD drive I stick it into.

    Might be a similar problem here...

    As for the burn times, it would be faster to burn from DVD to HD to CD than from CD to CD if both his DVD and CD drive are on the same IDE channel. You run into Bus Mastering problems that cause performance slowdowns when both optical drives try to access the same IDE channel.

    Is he closing the CD? Write-on-the-fly programs often won't do this until the disc is full. Check the settings when you go to burn.

    True -your HD will be able to transfer the data much faster than any CD drive. This technique is often used for making multiple copies. It usually doesn't pay off if you are doing just one copy, due to the extra step involved (copying to HD first)

    Try CDcheck

    That's what buffer underrun protection is for ;)

    He timed that copying using the writer for both the reader and the writer.
    he said that when he tried disc to disc using easy cd creator it took the longer time. I have him checking to see in easy cd creator if its writing to the HD first ot if its set up to copy on the fly... I think that might be his problem... I told him to look for a copy of CloneCD to use for copying disc to disc anyway, that it works better for that anyway...

    Thanks,
