Pburn: need to recover data after bad burn

#1 Post by steve_s »

I burned 3 dvd's full of data using pburn...have always been successful with pburn in the past...now nothing sees these dvds at all even though I can look at the surface of the disc and see clearly that it burned...

Is there any way I can salvage these dvds and make them readable? Any way at all?

I know that under Windows, you could try programs like these to attempt to recover data from CDs/DVDs. ISOBuster is the one I see mentioned most of the time, and that type of program usually tends to be shareware/commercial software.

I'm not sure if there's anything that'll work under Linux, though. :|

I think there is, but I can't remember what :(

BTW, I've heard isobuster works in Wine.

You could try with dd, it has to be a way of get the whole DVD's back, bit to bit... I was thinking in something like this:

Code: Select all

dd if=/dev/srX of=/mnt/sdX/temp.ISO bs=512 conv=noerror,sync
This way you'll copy the whole DVD to an ISO file, even the sector with fails on it. Off course, be careful of replace the drives and devices names.

Hope this get you a hint...
Good luck.

PS: There is an utility called 'ddrescue' somewhere.

Maybe Photorec?

I had some success reading from CDs that looked otherwise blank (I think the person who put the data on the CDs used Nero or some such under Windows).
PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from hard disks, CD-ROMs, and lost pictures (thus the Photo Recovery name) from digital camera memory. PhotoRec ignores the file system and goes after the underlying data, so it will still work even if your media's file system has been severely damaged or reformatted.

Oops, then something went wrong...
As an image worth more than a crappy explanation, see the caps.
(The second one is the same, without the extra parameters in the command).
You could also try with "notrunc" parameter between noerror and sync.

Photorec is good for what it does - scanning raw data on the disk and recognising file fragments. But it doesn't try to actually read the filesystem on the disk. Programs like isobuster do.

Thanks, Gustavo, but that's what I get:

Code: Select all

cd /dvd-recover/
dd bs=512k conv=noerror,sync if=/dev/hdc of=disk1.iso
dd: opening '/dev/hdc': No medium found
Yes, dev/hdc is how it is identified on this pc, no idea why (in both Gentoo and Puppy). I know 'cause I can go

Code: Select all

eject /dev/hdc
and it opens.

disciple: isobuster costs money, and steve no gotty money. It lets you run a trial version, but I can't see what it is I should be doing...nothing jumps out at me...suggestions?

Sorry, I only used it once, a couple of years ago. But I didn't think it was terribly hard to figure out.
Have you looked in the help?

AcetoneISO, is a feature-rich and complete software application to manage CD/DVD images. Thanks to powerful open source tools such as fuseiso, AcetoneISO will let You mount typical proprietary images formats of the Windows world such as ISO BIN NRG MDF IMG and do plenty of other things.

Well for my two cents i'd reccomend safecopy I don't know if anyone has a pet out for it but I have one made if you wanna try it.

safecopy is a data recovery tool which tries to extract as much data as possible from a problematic (i.e. damaged sectors) source - like floppy drives, hard disk partitions, CDs, tape devices, ..., where other tools like dd would fail due to I/O errors.

AcetoneISO is all about different types of CD/DVD image files, not about reading defective disks.
