    Unable to format BD-RE 50GB

    Hello, I've got an odd issue with a Panasonic 50GB BD-RE disc: I can't format it for re-use. This might have some bearing on the issue: before writing on a BD-RE disc for the very first time, I need to format all my BD-RE media first with Nero 8, then for a second time with ImgBurn. If I skip formatting by Nero 8, ImgBurn claims the disc is not empty. After that, a quick format by ImgBurn is enough -- though some Philips BD-RE media needs to be re-formatted with Nero 8 every now and then, and I've been forced to do a Full format on a couple of discs too. I haven't ticked the box "Prefer Format Without Spare Areas", but I have ticked the "DVD-RAM / BD-RE FastWrite" box. I have two BD drives, a Panasonic LF-MB121 and an LG GGW-H20L, both with latest available firmware. I've tried formatting the 50GB disc on both; tried both quick and full formats as well. The disc has been written on only once; with ImgBurn 2.4.0.0, and it performed flawlessly. Earlier today I needed to empty the disc and burn something else on it. I did a quick format with ImgBurn, and was surprised to see a pop-up window, displaying a number of media types and asking me to select one. I don't remember seeing such a pop-up before. Anyway, I chose BD-RE and clicked OK. Format appeared to pass without problems, but afterwards ImgBurn displayed a "Disc Not Empty" status message. Closed ImgBurn, ran Nero 8 and tried to do a quick format, but this popped up: HL-DT-ST BD-RE GGW-H20L: This disc in not rewritable and therefore cannot be erased. Please insert a rewritable disc. Next I ran Panasonic's WPTool to see if the disc had somehow been write-protected. The app reported "An invalid disc is inserted." Panasonic's DVDForm tool claims the disc is "Unsupported". This happens to be my only 50GB BD-Re and I'd really hate to lose it. Any advice is heartily appreciated. thanks, :: colin

    Alcohol was ancient, I uninstalled it now. Daemon Tools is the latest one, and it uses SPTD 1.56. I uninstalled it as well, just in case. Let's see if this had any effect. First test after rebooting, with Auto calculate enabled: profile remains BD-RE after dragging some data into source box. Looks like we solved it! I'll do some further testing, but it sure looks like it was either Alcohol or DT, or both, that caused the odd behaviour.

    Did a bunch of tray cycles. 'Prefer' box unticked- 10/10 cycles profile comes to BD-RE 'Prefer' box ticked- 10/10 cycles BD-RE Then I tested what happens when profile is BD-RE and I drag some data into Source box, with Auto calculate enabled. 10/10 x BD-RE is replaced by BD-ROM. Profile stays as BD-RE if I disable Auto calculate.

    Alcohol 120%, Daemon Tools, AnyDVD HD - any of these a possible culprit? I keep AnyDVD HD disabled when burning, though. During the previous BD-RE/BD-ROM profile swapping I didn't have AnyDVD HD loaded in memory at all. Alcohol and DT are also disabled, i.e. there's no tray icon for them, and neither is there a context menu for either one.

    Still under warranty, luckily How is that even possible? Drive reported BD-RE, I dragged data to source box, and profile is changed to BD-ROM. If there's no refresh from ImgBurn, how would you explain this? (I'm not claiming ImgBurn does a refresh, I'm asking for a theory ) Most of my PCs are from stone age, but I do have one other PC I could try the drive in. Will take some time to test, though. The drive resides currently in my video editing PC which has loads of various burning apps installed. It could certainly be a driver issue, but I don't know how to even start investigating that. I'll test this once the current burn is done.

    Unable to format BD-RE 50GB

    This is starting to get very mysterious indeed. I ran ImgBurn with the 50GB disc in LG drive, 'Prefer' box NOT ticked, and... Current profile: BD-ROM. Write button disabled. Ticked the 'prefer' box. Ejected tray, inserted tray... Current profile: BD-RE. Write button enabled. Dragged 40GB of Blu-ray data into Build window. Boom! Current profile: BD-ROM. Write button disabled. Deleted data from Build window. Unticked the 'prefer' box. Ejected tray, inserted tray... Current profile: BD-RE. Write button enabled. Dragged 36GB of Blu-ray data into Build window. Whoosh! Current profile: BD-ROM. Write button disabled. Ejected tray, inserted tray: Current profile: BD-RE. Write button enabled. Clicked Write button. Pop-up: "Data will be overwritten. Continue yes/no?" Clicked yes and writing commenced. Drive reports profile as BD-RE, but when you drag data into Build window and check again, profile's been switched to BD-ROM. What on earth is going on here?

    It worked. The 50GB Panasonic BD-RE I feared would be fit only for garbage burned fine. The data on the disc is OK, too, since the movie is right now playing on the PC next to me. It's the same disc which Nero 8 couldn't quick or full format; the disc which ImgBurn was unable to format or write on while the "Prefer properly formatted" box was ticked. I unticked the box, write button was enabled and the disc burned fine. This has to have something to do with quick formatting brand new discs with Nero 8 before using them with ImgBurn. What do you think?

    Unable to format BD-RE 50GB

    Whoa, hey, stop the press! I took out another Maxell BD-RE 25GB. This one was burned with Nero 8. Started ImgBurn, ticked the "Prefer properly formatted +RW" box, closed ImgBurn and started it again. Dropped some ~20GB of Blu-ray data into Build window. Inserted disc into LG. Write button is greyed out, status reads "Disc Not Empty". What the...? And then I noticed that 'Current profile' reads "BD-ROM". It's possible that previous Maxell had also been reported as BD-ROM. I just realized that scrolling down the Device window, there's a Physical format information section which lists BD-RE. It's quite likely I took note of that and totally neglegted the 'Current profile'. So! I unticked "Prefer properly formatted +RW", ejected disc, reinserted it and boing! Write button is no longer greyed out and Current profile says BD-RE. This got me thinking (about time, too). I ejected the Maxell, inserted the 50GB Panny BD-RE.... and ImgBurn lists the Current profile for it as BD-RE -- and Write button is not greyed out. Clicked the Write button... and LG started writing on the disc. It's done 23% so far, at a steady Write rate of 2.0x. Lessons learned so far: 1) I'm an idiot. 2) Sometimes it pays to play with tickboxes. 3) If possible, don't use Nero 8 for anything.

    I'm not trying to pick a fight or say you're wrong; I'm simply reporting what I saw & experienced, that's all. Here's a start of a hypothesis: I've used Nero 8 to Quick format all my brand new BD-REs before Quick formatting them with ImgBurn. There was a good reason for this, but I've forgotten what it was. It had something to do with being somehow unable to use (or quick format, perhaps) new discs with ImgBurn, unless they were first formatted by Nero. Might that have something to do with any of this?

    Ehh, sorry, what? First the write/build button was greyed out, then I unticked the box, and the button was no longer greyed out. Looks to me like unticking sure did something This was a different disc altogether; a Maxell 25GB BD-RE and drive reported it as BD-RE. But while we're on this subject, any idea why the drive would report a BD-RE as a BD-ROM? Please note that this only happened after I used ImgBurn's Quick format on the disc. Is it possible to somehow 'override' the drive and force... hmmh, probably not.

    By the by, I just noticed this seems to be incorrect. I placed a previously burned (with ImgBurn 2.4.0.0) Maxell BD-RE 25GB in the LG drive, and the Write/Build button is greyed out. Below that, the status line reads "Disc Not Empty". Certainly looks like the disc needs to be emptied/formatted first. edit: Unticked "Prefer properly formatted +RW" box and now ImgBurn allows burning without formatting first.

    Indeed. Ridiculous, isn't it? I haven't found the time to try another full format on my Panny media yet. Care to hazard a guess what settings (FastWrite, Format without Spare Areas) I should use?

    Great, thanks. Looking forward to your discoveries.

    In all seriousness... the 40 euros I paid for that disc is heck a lot of money to me, especially at the moment. You guys might be loaded, but I'm not

    OK, but what should I do when I'm done painting the house and format's still not finished?
  17. colinhunt

    Unable to format BD-RE 50GB

    I'll try that in a while; need to finish another burn first. No, not yet. Full erase takes forever and a day but I'll give it a shot soonish. Should I have Fastwrite enabled or not? Could that have any effect on the matter?

    Not quite. Panasonic drive reports BD-ROM no matter what I do. I can 'fool' the LG drive into reporting BD-RE by having the disc in the drive when I run ImgBurn, but when I try to format the disc (or perform any operation) LG sees it as a BD-ROM (apparently) and ImgBurn asks for media type. I've scoured the net for BD applications and none of them are able to format this particular disc. Alcohol 120% gave me a glimpse of hope. It refused to format the disc at first, but I ejected and reinserted disc and it actually started formatting.. only to stop a couple of seconds later, saying the disc is not compatible with operation, or something along those lines.

    I knew that about +RW and RAM, but not about BD-RE. Thanks for the tip. Too bad it's of no help with this current problem I'm having...

    OK. The reason I asked is quite simple: the disc was working, then I ran ImgBurn's Quick Format on it, after which the disc was borked. It's certainly just as likely that the drive malfunctioned. I don't actually care much about how it happened -- I'd much rather see a solution so I could use the disc again. Dunno if this info has any bearing on the matter, but... I've got some BD-RE 25GB media (Philips) which can't be formatted with ImgBurn's Quick Format. ImgBurn says the formatting went through OK, but then it reports that the disc is not empty. I usually get round this by running Nero 8's Quick Format on the disc, followed by ImgBurn's Quick Format. A couple of times that didn't help and I had to run ImgBurn's Full format on the disc.

    A couple of questions sprang to mind. 1) How come Nero 8 and ImgBurn seem to format BD-RE discs differently? 2) ...and what's the difference? 3) Any chance of ImgBurn having a bug which results in BD-RE 50GB media being formatted incorrectly, resulting in a disc which appears as BD-ROM?

    If there was a disc with LG, it's now vanished into the black hole otherwise known as this room. Panny came with DVDForm which refuses to recognize the disc. DL RE media is stupidly expensive which is why I have only one. It would be good to compare results, certainly. The donation I made a while back isn't enough to cover that cost, however... maybe I should donate a bit more

    Yup, that's what LG is doing. However, the pop-up window for media type still appears even when it reports the media as BD-RE. Something's quite wonky with this media...

    Ran ImgBurn first, then inserted media into Panasonic drive, which reports: MATSHITA BD-MLT LF-MB121 BD03 (USB) Current Profile: BD-ROM Disc Information: Status: Complete Erasable: No Sessions: 1 Sectors: 23 652 352 Size: 48 440 016 896 bytes Time: 5256:06:52 (MM:SS:FF) Supported Write Speeds: 2x TOC Information: Session 1... -> Track 01 (Mode 1, LBA: 0 - 23652351) -> LeadOut (LBA: 23652352) BD Disc Information: Disc ID: MEI-T01-01 Disc Type: BD-RE Inserting disc before running ImgBurn gives the same result.

    Certainly it has. I mentioned that in my initial post. It's been written to, but only once, using ImgBurn. I'm trying to empty/format it now.
