A friend gave me a home-burned copy of XPhomeSP3 but I can't read it on my 2002-vintage machine, presumably because it was burned too fast.

I made a slower-burn copy of the CD on another machine but ImgBurn says "Warning: requested 4x, got 16x". It seems the Imation blank CDs have a minimum burn speed of 16x. (although it doesn't say that anywhere. It just says "1x-52x")

The DVD reader is definitely less than 16x. What does one do in such circumstances? (no jokes about boat anchors please

Cant you change the burn speed in Imgburn? Sounds like shoddy blanks to me. Ive always burned at the max speed. Never had any probs with the CD after

Yes I chose 4x. I now see that the Imgburn discovery dialogue actually says 16x is the lowest write speed

Are you using a DVD burner or a CD burner? This is happening because for whatever media code is in the imation discs, the burner's firmware says 16x. So even though the discs can be burned from 1x-52x, the slowest the burner can do them is 16x.
I guess you are using a dvd burner? In general, CD burning on dvds is a bit of an afterthought, and CDs are best burned on an actual CD burner.

Burning slower does not always give a better burn quality. In some cases, it can result in WORSE quality. My experience has found that burning about half the maximum speed gives pretty good results on my dvd burner (NEC).

Yes it is a DVD burner. But it seems to be the discs not the burner. Here's what ImgBurn says about a blank CD:

ASUS DRW-22B2ST 1.00 (ATA)
Current Profile: CD-R

Disc Information:
Status: Empty
State of Last Session: Empty
Erasable: No
Free Sectors: 359,844
Free Space: 736,960,512 bytes
Free Time: 79:59:69 (MM:SS:FF)
Next Writable Address: 0
Supported Write Speeds: 16x, 24x, 32x, 40x, 48x

ATIP Information:
Disc ID: 97m26s66f
Manufacturer: CMC Magnetics Corp.
Start Time of LeadIn: 97m26s66f
etc
>>>>>>>>>>>>>>

If I put in a blank DVD the 'supported write speeds' are different and go down to 6x

Maybe try clicking on the little green running man image in Discovery if visible, then add/update the speed (green cross) for the Disc ID (e.g. 4x), and also select for the device (if it does display lower speeds, e.g. 4x). Both should be visible in the dialog box. Then click OK, to get back to main window.

I was going to say update the firmware. But, there is no update or any version on the ASUS site

Are you trying to copy an actual CD > CD or ISO image to CD ?

CD to iso on HDD then iso to the original (multiple files) on a new CD -

But I have now got it to go. I retrieved an old IDE CD drive and it read the 16x burn OK

I must say that using the integrated-SP3 version of XP is the way to go. I hadn't appreciated how much time and effort it saves:)
