i have a problem with my samsungDVD drive. i have 2 DVD drive, asus and this samsung. normally i just use the asus drive to do everythings, and this samsung drive just for read if only the asus can't recognize some disc. so its very rarely to use the samsung drive.
i just realize this problem while try installing ubuntu 10.10 or any other live cdlinux because its halted while trying to read the disc or even to recognize this samsung drive!. they (linux live) always point the same error from ata1 which is my samsung drive.i need to unplug the samsung drive so i can go on to continue installation.same result too while trying to booting after linux installation,it said my ata1 drive "to long to respond".
i checked in my both windows xp and 7 are no problem to boot,but can't read any disc, cd or dvd,empty or filled.(the led drive keep blinking forever). even the ImgBurn (burning program) failed to start,its takes forever just to initialize the drive, and i need to manually reset my computer to end this.
so i assume this is hardware issue than the OS problem, but not the lens problem,because its rarely to use ,so i downloaded the firmware and flash it, my default firmware are SB00 and flash it to SB01 and SB02, but still not solved the problem. canging the IDE cable, set cable to master or slave, and set jumper selection to master-slave-cable_select still no result...
Yup.. I have swapped an antique philipsdvd drive for a samsung recently.. and it's not as good as the 9 year old one..
check out hdparm command line app.. allows hard reset of drive and setting dma and read ahead and the like.. my old philips was a biatch until I did a forced hard reset on it.. then afterwards it was a gem.. must get round to doing that with the samsung and see if it helps.. needs full root.. wouldn't just use sudo for serious hardware tinkering
debian:~# hdparm

so hdparm -w <device> .. and see what happens.. make damn sure you are pointing at the samsung drive tho... forced reset of a mounted and running hdd isn't a pleasant experience to recover from
but the problem is, i can't login if my samsung connected. its always halted saying my ata1 got problem... it is save to connect IDE drive while power on?
i managed to login with my samsung drive connected using openSUSE 11.13 (after keep yelling that one of the drive got problems ofcourse,but atleast it allow me to continue), and according 'Hardware Information' my samsung name are '/dev/sr1'. so i ran this command (root),..
hdparm -w /dev/sr1
but its said,..
-----------
/dev/sr1:
resetting drive
HDIO_DRIVE_RESET failed: Inappropriate ioctl for device
-----------
