Windows 7: 7 64bit USB 2.0 External BluRay burner problem

Hi!

i recently bought a slim bluray burner Sony Nec Optiarc BD-5730s. Since i had a PATA dvd-rw before that in my laptop (HP 9500t cto) i had to buy an additional external enclosure. I bought it. it doesn't have any labels on it so i don't know who the manufacturer is.



and the problem is...

everytime i connect the usb 2.0 enclosure (with the burner in it, ofcourse) in win 7 64bit shit happens. and by "shit" i mean: when there is no disc in the drive everything looks ok. my computer and device manager recognize it and everything is ok. when i put in the audio cd i could easily playback it. but when i put in a dvd or a blank bluray win just goes crazy. every 5 or so secs i hear the sound when something is plugged in using usb and another 5 secs that it's disconnected.
when i went to my computer that's exactly what happens. the BD -ROM icon just keeps on appearing and disappearing. the same thing happens in the device manager.

i tried plugging in the burner while in win vista and xp and everyhing is fine. i also managed to burn an .iso to a blank bluray without any problems.

so, since i'm mostly using win 7 64bit, plz tell me what the hell is happening?!

thx!

Is the dvd compatible with win 7?

why wouldn't it be if everything seems normal when there is no dvd or bluray in the burner?

furthermore, i made a dual boot with vista ultimate x64 on the other partition and the same thing happens.
guess that it isn't due to win 7 but something to do with BIOS...
any suggestions?

btw, when i enter BIOS there are very few options to change. i can't even find where is my usb burner mentioned...


and if you are wondering why i wrote that i could use every feature of the burner normally on vista and xp, that was on other machines, other that the HP laptop.

Dose the external drive has is own power supply or is it just using the USB connector?
The Blue Ray may be drawing to much power for the usb to handle

nope. it couldn't be that because i told u already, i got it working on other two computers running vista and xp, both 32bit. i even burned a bluray disc on xp without the power supply cable.

A laptop may not provide the full usb 2.0 voltage that a desktop will since they have a small power supply.

nope, not that either. since i can read the bluray disc on a 13" laptop (and the HP one is 17". i guess 17" provides more power than a 13" one).

i even tried your theory and connected the data cable to my HP laptop and the power supply cable to my desktop. still the same.

i guess it has to do something with bios or 64bit system... any thoughts?

The only place it will show up in the BIOS is in the boot options. And then only if your BIOS supports booting from a USB device. Other than that the BIOS doesn't really have anything to do with external USB devices. I have an external HP DVD burner, its not blue ray but it is LightScribe capable. I haven't had any problems burning DVDs on my x64 win 7 system. You could try going into control panel and turning off "Autoplay". There might be a program launching when a blank disk is inserted that is causing your problem. I think there is a "HIDE empty drives" setting in Folder options somewhere too that you might want to look at.

thx for the advice but nothing happened....

i'm really starting to lose it...
can't find the reason to this nonsense.

i tried it also on win 7 ultimate x64 on my desktop and it works flawlessly.

i also updated my usb drivers on the HP laptop... i really think that it isn't due to windows but something else is in play here but i don't know how to determine what.

any help is appreciated!!

I don't know what to tell you. I have a Sony Walkman mp3 player, works fine on all my PCs except my old XP beater. When I plug it in I get the detected, undetected beeps like you do. It acts like you are plugging it in and unplugging it again over and over. Works fine on my other XP PC though. I didn't bother to figure out why because all i wanted to do was recharge it on that PC.
