Need help with Drag&Drop from a DVD

To explain my problem and question, I need to tell you what I do and what happens. I have a folder on my hard drive; we will call C:/Johnny. I have a DVD disc with three big files on it. Call them Nancy1.tib, Nancy2.tib and Nancy3.tib. These files are compressed. I put the DVD disc into my D drive. I open Windows Explorer. I can see the folder name Johnny under C drive in the left panel. I click on the D drive in the left panel and the three file names now show in the big right panel of Windows Explorer.
I next right click on the file name Nancy1.tib, hold the button down, and drag to over the name Johnny. I release the button, and then click on "copy here ". A screen comes up showing stuff being transferred [the little moving symbol flipping from left to right]. After several [say seven or eight] seconds, an error screen comes up, whicn says in its entirety:

"Cannot copy Nancy1.tib: Data error (cyclic redundancy check) "

I have no idea what that means. But the strange thing is that I can sucessfully drag and drop the other two similar files [Nancy2 and Nancy3] from the DVD disc to the c:/Johnny folder!

QUESTION: Is the file Nancy1 wholly corrupted? OR is it a usable file but for some reason not transferrable by Drag and Drop procedure? If the latter, what is causing the trouble?

QUESTION 2: Is there some other procedure or method by which I might be able to transfer the DVD file Nancy1 to the hard drive folder C:/Johnny?

I surely will appreciate your help on this.-----------Lee Mitchell

 

Steve: Thanks for reply. Yours was a good suggestion, but it does not work. I went to Windows Explorer, clicked to "select" the troublesome file name, clked Edit, then clicked "copy ". I looked in Clipboard Viewer, and, yep, that file was in the Clipboard. Then I went back to Windows Explorer, brought the contents of my desired folder [Johnny] to the right pane, clicked on Edit, BUT THE THE DROP-DOWN PANEL DID NOT HAVE "PASTE" ENABLED. so I simply could not PASTE into that folder.

What am I doing wrong?

I also tried to "select" the troublesome folder in a Windows Explorer right pane, then clicked Edit, then in the drop-down I clicked "copy to folder ", then selected the desired receiving folder in the resulting browse screen, then clicked "copy ". The transfer started with the little symbol flipping from left-to-right, BUT AFTER A FEW SECONDS THE VERY SAME ERROR SCREEN [see original post, below] popped up.

What do the words "cyclic redundancy check" showing in that error screen mean??

If I knew that maybe I might fix the file I am tryong to transfer.
Thanks for your help!!! ----Lee

 

XP does not have nativate support for DVDs, including drag and drop.

If you have added third-party support, be aware of some important differences between DVD (and CD) types. Only certain formats for both CD and DVD support rewritable volumes. For example, if your DVD is -R, what you are attempting to do is impossible.

The same would be true for most CD sessions. If the CD is CD/RW, and the session was not closed after the initial writes, and the original copies were done as multi-session or with third-party support for UDF (which XP natively does not support) then all would be possible. But not under native Explorer.

 

Thank you PeteC, I completely misread the original question.
My apologies.

I was thinking that the error messages from a third-party program for a DVD write are less than reliable at times. I focused on physical media, and the session status of the disk after the previous writes.

CRC is as you mentioned an indication of a hard read error on the original file. I would be curious as to the size of the copy being attempted. Sometimes a large file can throw a CRC error just because of its size. There are ways to modify Explorer for these instances (the best one being up-to-date on Service Packs and hotfixes).

If the error is only this file, then as you stated the file write is corrupt. If it happens to other, large, file writes to the device, I would examine and update the third-party support being used for the DVD device.

As a final note, the issue might be a physical failing in the DVD device itself. See if the error re-occurs on a different machine, same disk, same copy operation. That at least solidifies the claim of a hard error on the original DVD write for the file if the error re-occurs.

Again, thanks Pete. My bad read of the issue.

 

PETE: Thanks for your reply. I am late gedtting back to you, because I went to the link you gave me and learned a lot.
You are correct [wow! what knowledge] in that the files I am dealing with are for Acronis True Image 9.0; they have the extension .tib
I have run the program to make a "full image" of my entire hard drive [drive C], the only hard drive in my computer. I have put that "image" onto six DVD's, and they contain 12 files [called Volumes by Acronis]
I tried to transfer those 12 files into a folder on the hard drive [it has lots of space] by drag and drop. It worked OK for files 1-3 and 5-9, and11,12----but the transfer of files 4 and 10 failed ---with the "cyclic redundancy check" error screen. Thanks to you, I now know that the files 4 and 10 are corrupted, are essentially useless, and that my Image on six DVD's is very probably worthless for doing a Recovery if my hard drive totally crashes.

Do you have any thoughts as to why ten out of the twelve files seem OK but two were corrupted when put on the DVD, or thereafter became corrupted? The discs have been handled very carefully.

I am using DVD+RW discs; they seem to work well. Do you know how I can erase those [so I can try to make a whole Full Image] without formatting them with UDF/PLA? My only formatting program, which will erase, does that format---and I have had trouble using that format with Acronis True Image. Instead, I have found that the Memorex DVD's right out of the box work best with True Image.

Also, you suggest Immediately "validating" the Image. How do I do that after making a Full Image onto DVD's?

Thank you, thank you for your help and thoughts-----Lee

Validate by again using Acronis.
Point to the image on the first disk of 12.
Ask Acronis to validate the image.
Be prepared to stick all of the disk volumes in the drive in sequence when prompted.

I must admit to some envy for you. I love Acronis True Image. But I can image (with compression) my entire main working machine three times on a single DVD.

 

BILL C: Thanks for your good tip. I am starting the a "validate" and it is running. Looks like it will take eons of time.

From your tip, I fiddled around in the Acronis main screen until I clkd on Tools and found "validate ". I inserted my first [of six] DVD's into the D drive, then started the Validation process by "selecting'" the first file of the twelve files [ "Volumes"]. A screen came up by which Acronis said, in effect, ".....This is the first Volume of this Image. Please go to the last volume which was created for this Image "----or words to that effect.

So I changed to the last of the DVD's and selected the last of the twelve volumes. The validation is running, says it will take hours for the volume to be completed. Looks like it will be a very long time before it gets to and deals with the Tenth volume---which is one of the two that appear to be corrupted.

What a mess. Maybe I should just try to make an entirely new, fresh Full Image,--and hope I get all of the stuff onto DVD's without any corruption.

THANK YOU for your help [and sympathy]!!!--------Lee Mitchell

 

Pete C: Thanks for your latest reply. The "validate" I ran looked at my vol. 12, then 11, and then conked out on Vol. 10-----which was one of the two I could not transfer from DVD to a hard drive folder [and that Vol 10 kicked out a crc error screen]. So now I know that two of the twelve Volumes of my Full Image are grossly corrupted. Therefore, I will throw out that entire Full Image ====and start over completely to try and make a good Full Image.

Thank you thank you for your help.

I think we can close this thread now. Hope you will do that, unless the BBS just lets time run out to let the thread dissapear.---------Lee Mitchell
