guys this is getting the worst time of my life first my p3 fujitsu laptop got screwed which is still not repaired and the second blow is this my p4 toshiba lappy satellite series----s1905with 2.4 ghz proc and i think its 845 mobo and m6 64 mb ati card has started giving me problems the os used is win xp if u guys require any more details just ask me and i will do the same.

so the problem is all of a sudden my combo drive of the lappy has stopped detecting any kinda cds but it runs all kinda dvds smoothly , weird problem, god why me, catch some of the techies outta here ;)

i cannot even format and reinstall xp as got only xp in cd rom version , also nero does detect it as a combo drive and in info tool too there are tick marks for the combo drive the drive is toshiba dvd rom sd-r2212
 
prolly lens is busted...the same happened to my DVD ROM...reads DVDs, not CDs...got a replacement
 
i've seen it with many optical drives, when the head gets weak, it can read pressed CD;s well, i mean the Originl Pre-recorded ones but i cant read the Written CD-R;s,

Sometimes even dust on the optical lens could cause your drive to act funny. Try getting the lens cleaned from a professional service centre.

Never ever use IP or acetone like hard Dissolvents on the Lens - they permanantly damage the Lens

very true.
it is stated here on the site to use moistened cotton buds, if at all needed, Vicky most probably the laser power level for cd read/write operations are screwed up.
There are two small variable resistors (v/r) on the lens assembly. one controls the laser power level for dvd operations and the other for cd operations.

by turning these v/r's a small amount (about +/- 15 to 30 degrees ) many a times this problem is solved.

but the problem for you will be to identify which v/r controls which (dvd /cd ) operations. and if you mistakenly use the wrong v/r you will loose the ability to read / write dvd's even hence it would be advisable for you to take this unit to a good repair shop and get the laser level re-calibrated.

no amount of bios flashing will help as it is not a bios problem. infact most of the times newer bioses are released by co's so that more and newer discs are easily recognised. (disc compatibility issues) thats all.

flashing should be done only if user faces some issues which are specifically mentioned in the readme.txt file of the bios.
