ATAPI DVD A DH16A1L won't recognise blank dvd

Hi,
I re-installed my cd/dvd drive after the DMA turned off. The DMA is back on but now the drive will not recognise blank dvd's (+R or -R). The drive will play dvd movies but when i put in a blank dvd it recognises it as a blank cd on the cd drive. I have checked the cables in the drive and they are plugged in fine. I have also removed all my burning software and tried to delete the upper and lower filters but their are none there ( I followed the instructions from the HP Compaq website). Any ideas how to fix this??
Thanks my dvd wont recognise any disc written or blamk

Turn Direct Memory Access (DMA) on or off

is usually turned on by default for devices such as CD or DVD drives that support DMA. However, you might need to turn on DMA manually if the device was improperly installed or if a system error occurred.
  1. Click to open Device Manager. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
  2. Double-click IDE ATA/ATAPI controllers.
  3. Under IDE ATA/ATAPI controllers, for each item that has the word Channel as part of its label, right-click the item, and then click Properties.
  4. Click the Advanced Settings tab. Under Device Properties, select or clear the Enable DMA check box, and then click OK.

Problem with LITE-ON DVDRW SHW-160P6S ATA Device


There is a whole bunch of helpful stuff at http://www.tomshardware.com/forum/196090-32-lite-dvdrw-160p6s-burning-problems
Seems that the drive may overheat, and will need replacement if in warranty. Some advice given: get another type drive. Also, check the device manager and make sure it's running in DMA mode and not PIO mode. If you have an nForceX mobo and using the SW IDE driver, reinstall with the normal IDE driver and try again. In device manager, check under IDE ATA/ATAPI controllers. Right-click and select properties on the IDE Channel your DVD recorder is attached to. Transfer mode should be set to "DMA if available". Current transfer mode should be "Ultra DMA Mode 4". If it says Mode 2: Your drive may be experiencing problems which are causing windows to drop its speed. There is a support article with a fix. To surmize:

After the Windows IDE/ATAPI Port driver (Atapi.sys) receives a cumulative total of six time-out or cyclical redundancy check (CRC) errors, the driver reduces the communications speed (the transfer mode) from the highest Direct Memory Access (DMA) mode to lower DMA modes in steps. If the driver continues to receive time-out or CRC errors, the driver eventually reduces the transfer mode to the slowest mode (PIO mode).

If you have dropped from DMA mode 4 to DMA mode 2, and you have a spare ribbon cable, you may want to try swapping it out. Also, if there is another device on the same channel as the DVD drive, try disconnecting it.

ATAPI DVD A DH16A1L not reading blank dvd's


This is a firmware issue that I am also having the same problem with. The only real solution is to purchase a new drive temporarily, since the DH16A1L firmware update is precariously a "Vista Only" update. If you have XP or Windows 7, you are SOL, thanks to the lovely folks at HP.

This was my business' last purchase of any HP hardware, we have had enough of the fried laptop mobos and issues as such. I hope everyone follows suit

CD Drive will not read disks


If you only think youve installed correctly, double check the jumpers on back whether master or slave depending on which ide cable is used and whether there are two devices or one on the ide cable. was the cdrom recognised by windows when it was rebooted after install and automatically installed? check on the device manager on the ide/atapi controllers see if ultra dma is being used.

Help Please


Sorry mate i dont understand all you have written, but this is what i use as nero wont copy most films and just wastes the discs, to copy them you need nero installed, then download a free program called dvd shrink which can be found on google. run dvd shrink put film in drive, click open disc select film, then click backup will rip it to drive then spits out disc and you put in blank and it should work fine. Hopefully this is problem you are having. All the best John
