Question

multisession dvd reads ridiculously slow in win7

Apr 12, 2012 5:32PM PDT

win7 multisession dvd reads ridiculously slow
never had tried formatting a dvd as multisession before...now i know why

burned it last night on a win7 home edition pc (single layer dvd)

trying to read it on my win7 enterprise pc...one of the files copid fine..normal speed..with the other 3, windows explorer gets slower and slower and finally justhangs, the progress bar changes from green to red

i tried to find something via google about this and no luck

any ideas? thanks much

BTW i used the windows 7 burning wizard to format as multisession (where it says "use disc as a usb drive" or something like that...yeah, what a usb drive...took about an hour to burn 4 gb of data, now i cant read it)

***DVD drive is an ASUS DRW-2014L1T ATA


***ISObuster not working. After attempting extract from disc, it simply flashes a dialog for a split second and does nothing.

Found a free app called bad cd dvd reader. When I try to make a copy of the disc it crashes the program. It doesnt really amtter because I dont think it is recognizing the multisession disc.

That's not multi-session

That's called Live File System format, as shown by ]http://windows.microsoft.com/en-US/windows7/Burn-a-CD-or-DVD-in-Windows-Explorer.

I've never tried it myself. I do have a real USB-stick. So I can't tell if this is the normal behaviour (I don't think so) or if something is wrong with your drive (did you check it's in DMA mode, not in PIO mode?) or it was just a bad disk.
Anyway, http://www.isobuster.com/isobuster.php shows the program does support that Microsoft specific format, so there definitely is something wrong with that disk, whatever the cause.

In terms of DMA or PIO, the dvd drive is connected via SATA2, there doesnt appear to be a DMA option

Connected to an Asus P5K-E mobo

Thanks!

Indeed, for SATA there's no such option.

So that can't be the cause. So the cause remains unknown.

Buying a 16 (or even 32) GB USB-stick seems the easiest solution in your case. To burn data for archive purposes, use the standard 'Mastered' format and preferably a burning program like Nero or (free) CDBurnerXP. Personally, I've never used the burning features built into Windows.

burning this stuff as live file system was a 1 time deal. i'm just trying to recover the data that i burned. I'll never use this live file system stuff again....

About data recovery.

Look up ISOBUSTER and hope it can deal with it. http://www.drivesavers.com would be the best solution but I hope the data is worth saving.

I said I have tried ISObuster in the OP, and i said what happened when i tried it

I see Kees mentioned it too.

It's a good app to try.

And I see Kees mentioned ISOBUSTER for you in his first reply.

Sadly I think this is how most learn about how treacherous CD/DVD as a drive can be.

Maybe www.drivesavers.com is next?

same problem
Jul 11, 2013 10:41PM PDT

hey matt, i had the same problem as yours and i checked all the options but nothing helped. i did google searches, wikipedia and microsoft site( which kees mentioned). And the silly thing is that the dvd is showing that there is no free space except for about 116 MB from the total 4.38 GB , even though when i open it shows that the dvd is empty.. Im going with you. Never try multisession again . i didnt see the live file system format anywhere as kees mentioned....
