My old DRW-24B1st DVD writer is not working anymore. I can not recognize most of the blank DVD-R disks. I can not use it to burn DVD or CD. So, I have to buy a new one. I check the NCIX and at the last I bought a Liteon iHAS 124-14 24X DVDRW SATA Black
The ASUS DRW-24B1LT / 24B1ST is capable of reading and writing data on DVD±R/±RW, DVDRAM formats. It is a power saving drive and allows you to permanently delete the data on rewritable discs. This provides you with flexibility and efficiency in terms of multimedia data storage and sharing.
