i got a compaq sr2011vm it only came with a dvd/cd-r so a few days later i also bought a LG GSA-h22l dvd-rw. i installed this and left the factory cd-r installed, but after installing neither drive shows up. i also installed a different dvd-rw drive(it was a christmas gift i had to open) it didn't show up either. any help would be greatly appreciated.
Make sure your DVD RW drive's Jumpers and set to MASTER and the CDRW drives jumpers are set to SLAVE See this... http://peripherals.about.com/od/cddvddrivesburners/ss/installcddrive_3.htm Or this.. http://reviews.cnet.com/4520-6603_7-5118840-4.html That should fix it.
thanks that helped but still got a problem. it's showing both drives now but the dvd-rw is showing as a dvd-ram. since the dvd/cd-r was factory i left it along and changed the clip on back of dvd-rw to the slave.
If oit shows as DVD RAM then that's fine. Switch them over, factory one can go as SLAVE, it won't harm anything. Your main burner should be MASTER.
