did 10.5.3 changed -R DL to +

Same problem:

MATSHITA DVD-R UJ-85J:

Firmware Revision: FAV1
Interconnect: ATAPI
Burn Support: Yes (Apple Shipping Drive)
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW, +R, +R DL, +RW
Write Strategies: CD-TAO, CD-SAO, DVD-DAO
Media: Insert media and refresh to show available burn speeds

Kills (-RW) which are in excellent condition and have been using for well over a year suddenly dead with patchy write areas as seen in reflection.

Additional text is added bellow

Just posted that from System profiler and added post. Then realised it's looking kinda normal again! Bellow is what I posted the other night before going on a road trip for a couple of days:

MATSHITA DVD-R UJ-85J:

Firmware Revision: FAV1
Interconnect: ATAPI
Burn Support: Yes (Apple Shipping Drive)
Cache: 0 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW
Write Strategies: CD-TAO, CD-SAO, DVD-DAO
Media: Insert media and refresh to show available burn speeds

While on the road trip one thing did happen while I was away. I used it and without realising it ran the battery down. I was just playing an old game to amuse myself which was in full screen and got no beeps/screen-flashes or dialogues to tell me of the low battery. Closed the lid and later went to wake it again. But it refused to wake so I force shut-down. It refused to start again and thought it might need the cable. I didn't realise that is was out of power as I hadn't been using it for long. It stared on mains and showed the white page with the Apple logo, but instead of the spinner I got a row of dots that progressively changed to dark grey. Then the machine woke up from where it left off. only thing I can think of that happened that might have effected what ever my issue is.

Amendment, Tried to burn one of my (+R SL DVD) and it failed as has been for some time. The first disc in the spindle burned fine. non since. Sensor error message left right and centre from a single burn. Burns CD's fine. Never mind if I got anyone's hope up. Doesn't appear to have written anything on the disc. But the software tells me it's no longer writeable.

if 10.5.3 changed the drives firmware you would of downloaded a firmware update seperate and had to perform the update, which usually installs the application into system utils folder, asks you to reboot and performs the upgrade in the usual way whenever firmware is updated


firmware updates for apples are usually quite rare

Actually they are not rare.

Do apple include any Firmwares within an OS Update? I realise that when I installed 10.5.4 I wasn't put through a typical firmware update procedure, but just checking. Something has clearly gone off the rails with my ROM. I don't have access to a ROM cleaner just now, but will try that as soon as possible. But my gut feeling is it's more serious.

... I am not sure if this is relevant but I was having major problems with burning DVDs (so bad that Blank DVDs would continuously be ejected, DVDs that I didn't have a problem with prior to Leopard). I spent the past few weeks reading up on this issue and tried all of the suggestions, nothing worked. Today, trying yet another random solution that I came up with, I ejected my external harddrives (I have one USB and another Firewire) and et viola, everything is back to normal and I have burned 3 DVDs without the slightest issue.

Thanks for yoru thoughts. Unless a network drive counts I have no externals directly connected. Got nothing connected in fact. I might try shutting off the network later and see what happens. you never know.
