Burning DVD images, the Verify always fails

[jimboe]

Hi all,

I'm new at burning DVD's but not with computers, etc. and this problem's got me stumped. Excuse the long-windedness but I want all the details known for the DVD experts.

I've got a Sony DVD+-RW DRX-510UL (fw: 1.0f) for a few days now, and every single *.img file I burn (havent had any ISO's to try), burns successfully, but the verify ALWAYS fails at 94%, for every *.img file I've tried, with the error:

I/O Error
ScsiStatus: 0x02
Interpretation: Check Condition
CDB: 28 00 00 16 AD 80 00 00 01 00
Interpretation: Read (10) Sector 1486208
Sense Area: FO 00 00 21 ......(more numbers)
Interpretation: No Seek Complete

This is with DVD Decryptor 3210, burn-proof on at max (4x), or even when I tried once at 2.4x.

The only thing that changes in the error from disc to disc is the actual sector # and the hex numbers on the CDB line and the Sense area line- but the verify failure always occurs at 94%.

Here's the scenario.

I bought a 25-pack of Fuji DVD+R 4x blanks, and proceded to burn my first image file. I got the above error on the verify- I thought "maybe the 1st disc was defective.. strange".

I immediately made another burn from the same image, which DID go successfully through the verify. Then on a 3rd burn verify failed again.

Now since there's no way to verify "after the fact" a disc which has already been burned (at least not that I know of-- this would be great), what I've done is try to Mode->ISO->"Read" the burned disc back to a new image file on the hard drive, to see if it can read all the way through.

That works, with both my Aopen 16xDVD-ROM/AMH, and the Sony itself, and they both create images of identical sizes. I cant compare to the original img file since I need to erase it for lack of disk space, and anyway, DVD Decryptor makes MDS/ISO files while the originals are *.img files, so comparison would be impossible.

Now this has been happening with all the img files I've tried, and I haven't had a successful verify since that 1st img file, and also a 2nd img file which worked 1 out of 3 times also.

I've done about 4 or 5 other img files all with THE verify error, but the "Read" "after the fact" on all burns is always successful, so I've assumed that there is another issue here.

One other interesting to note is this. Most of the time, when I use DVD Decryptor to do a ISO->"Read", and I load the DVD in, the program doesn't recognize the disc properly, even after it has just been burned (I have been removing the disc from the Sony and trying the read in the Aopen. thinking, "...I'll try to read it on a different drive and see if I get any read errors").

This disc spins up, and the program shows Disc ID and some other info correctly, but there's no label associated with it (and some other vital info is missing), and the progrgam doesn't think it's a readable disk.

What I do is close DVD Decryptor, open windows explorer, put the DVD back in the drive, and the OS recognizes it every time perfectly as it pop's up (label and all) in windows explorer, and autoplay with PowerDVD kicks in (they seem to play fine, altho I'll admit I havent watched any of them all the way thru yet).

Subsequent to that, I take out the disc, restart Decryptor, click E, then L to load the disk in ISO-"Read" mode, and wahla, the program now recogzies the disc perfectly, and the "Read" works fine to create the image.

Also, the Sony seems to have crappy read speeds, only about 2x, whilst my cheapo Aopen DVDROM reads them up to around 8x. Strange.

So, are the burns good?
Could there be an issue with the burner reading on the subsequent verify based loosely on the "noted" problem I just decribed above?
Could all of the media I bought really be faulty or incompatible?
Could the burner be faulty?
Maybe something in my OS (XP) is screwed (ASPI? although Decryptor's log shows SPTI in use..)
Am I just overlooking something simple?

Suggestions or advice would be most appreciated.

Thanks.

Use DVDInfoPro and see who the real manuactuer of the disc is. Cause I had a caller have this problem ont he phone the other day. Turned out to be cheap disc. Maybe those are real Memorex in which case it could be your issue also.

if they are ricoh then its likely not the problem...

I will try that and let you know, but as I've said, none of the burns actually fails at all, ,and the subsequent "Read" to make an image from those discs goes without incident.

Also, DVD Decryptor says the discs are RICOH-JPN, or something like that.

"Read" to make an image from those discs goes without incident.

The verify option for ISO Write mode is a new feature and might be a little buggy

I found with DVDshrink 3.1.7.6 auto burning via Nero to be more reliable than by DVDdecrypter 3.2.1.0.
DVDdecrypter 3.2.1.0 now has a verify option - very handy, but out of the four burns I did using DVDdecrypter, two failed to verify - had lots of errors.
DVDdecrypter is a truly great product, so I put my failure down to faulty media. Still, I went back to auto burn using Nero and have been fine using the same media. I verify with DVDinfoPro.

I just tried DVDShrink and doesn't seem to like *.img files.

O well.

But are the disks playable in a standalone? I noticed you said you have'nt played a disk all the way thru. I've never tried to verify any of the DVDR's I've burned. I always figured if they play fine then whats the point. Besides years ago when I was into backing up PC games. A lot of times the disk's would not verify after being written. But would work perfect otherwise. So I never bothered verifying anymore.

[handyguy]

why not try Nero, it also has a verify option & does IMG files.

[jimboe]

I have tried them in the standalone and they seem to work fine (Just havent yet played them all the way thru). I will proly play one today.

Also, in my experience (which goes back longer than I care to mention ) , if a verify failed when I was copying floppies, it usually wouldn't work (not referring to copy protected stuff which is another matter).

Nero (6302) doesn't seem to handle *.img's. I'll try again tho to be 100% sure.

If you rename the file extension from .img to .iso Nero will burn them. (A trick that also works with other burning programs.)

I have Nero 6.009 and it will not verify a disc image burn (.iso) but RecordNow DX will.

[jimboe]

nice trick, I will try.

I just finished watching one of the images I burned, from beginning to end, ,so I guess the failure on the Verify's are inaccurate, so now it's more of a curiousity than a necessity to know why it's failing..

Must be the program, or maybe the fact that the writer is external USB..

dunno.
