I bought Samsung Combo SM-332 CD-RW (52-24-52) some 8 months back and initially it was quite good in speed though I had 128mbSDR ram.
But the more I used it the speed has declined slowly over a period of time
Earlier it used to copy a CD of 650 MB data in 2.5 minutes now it takes more than 6-7 minutes. I dont know why.. I have even changed my OS also to save time.... but no help. Above that now I donot get 52x option now in Nero! HEHE!
The drive platter doewnt go in if you donot insert a disk for long time where as many drives go in
There are ofcourse positive points like it never disappointed me in Buffer underrun, whatever be the source. Unless the power fails, the cd will burn normally and error-free.
There are some tips however to keep your drive in tact. Clean it ever 15-20 hr run with a disk cleaner.
Cover the CPU when not in use to prevent dust on lens.
Never open the CDRW drive as the laser is more powerful than in CDROM
If some of your CD roms are not readable, I heard of a software which can read them and its free to download.. get it...
Do not use cheap quality CDs for burning as they wont last long and also do not burn correctly.
