"DVD player is ok as can play DVDs."
Ok, good .
Can it read other burnable disks fine ?
As I said above...
"....burnable disks other than CD-R or DVD-R disks may not read properly in a drive they were not made in. "
E.g. all optical drives are somewhat "fussy" or sometimes very "fussy" regarding which media - brands and types of disks - work properly with them. A particular burnable disk brand / type that works / reads fine in one optical drive model may not work / read fine in a different optical drive model. Which media has been tested and has been found to work fine with an optical drive model is often listed on the optical drive maker's web site.
E.g. The only brand LG lists for all types of disks their burner drives can read and burn properly is Verbatim (in North America - in other places the same disks are often sold by the same manufacturer under another brand name).They also list other brands / types that have been tested and been found to work / read fine for individual types of disks.
(this can apply to any optical drive - you may need to update XP)
CD-ROM Drive May Not Be Able to Read a UDF-Formatted Disc in Windows XP
"However when a DVD-RW is put in the properties show.
CD drive - File Sys UDF- free space '0' byte - total size 127 mg.
The same disc in another laptop show propertis as
CD drive- File sys UDF - used space 290 KB- free space 4.37GB."
Is the first quote supposed to be
CD drive - File Sys UDF- free space '0' byte - total size 127 mb ?.
No used space ?
If burning software is not installed on that computer, or if you have re-loaded just Windows from scratch on that computer but have not installed the main chipset drivers for the mboard, then Windows may not recognize the optical drive properly and/or may not recognize the available free spae on a RW disk that has already been prepared.
Obviously, on the second computer, Windows recognizes that the RW disk has already been prepared so that 4.37gb of space is available for data - " used space 290 KB" is probably the space taken up by the formatting that is necessary so that data can be stored on that 4.37gb of space.
Windows always shows 0 bytes free space on a "factory" CD-rom or DVD-rom disk, or on a CD-R or DVD-R already burned disk. .
