Computer won't read disc.

Factual Questions
1

I have a couple of backups of programs my employer wrote (with permission, of course :slight_smile: ) that we use at work, so I could have access to them from home when needed.
They were burned to standard Office Depot CD CD-R discs.
The past month, my husband has added some new drives and RAM and such to my home computer and we’ve had to reinstall everything multiple times.

Now I’m having a problem with one of my work backup discs - it won’t read on this computer, although it did before the upgrade - same OS, same physical CD & DVD drives, motherboard, etc. I put it in to install & autoplay brings up just a blank window with the disc name in the address bar - like it sees the disc but can’t see what is on it. Searching it finds nothing, though the computer does see that the disc is full, with 645mb.

Examining Properties, it is in a format I don’t really know - IVIUDFS. :confused:
But popping it into any of the other computers at home, it reads fine.

Another work program backup disc burned around the same time, same program (Nero), same disc type, is a CDFS and has no problem showing the contents.

I made sure Nero is installed in case IVIUDFS is specific to that program, but it still won’t see the contents.
Googling IVIUDFS only brings up a handful of results, most if not all, in another language and using Google’s translation feature doesn’t really make it any easier to understand.
My husband may have fiddled around with the computer settings, but if he changed something, I haven’t a clue as to what is was and he doesn’t remember. :frowning:

I’ll try to provide additional info if needed, but I may need a little assistance finding it to provide.

For starts, here’s what DxDiag has to say:

Thanks in advance for your time. :slight_smile:

Bump.

Was the CD created with Nero InCD? If so, you probably should have finalised the CD. But you should still be able to read it if you’ve got the same version Nero on your machine. You did reinstall InCD, didn’t you?

From Quartz:

I don’t think that is the problem, as InCD deals only with CD-RW, not CD-R. InCD uses UDP format, and is never finalized. Then again, if it IS a CD-RW, for sure InCD must be installed, or whatever EZ-CD Creator’s UDP program is. But the OP specifically mentioned CD-R, not CD-RW. They are two very different beasts.

Alas, I have no real answer to what the problem is. I will look into it on Monday, when I am back at work and can run it by the other IT guys, and have access to my reference materials. I have never heard of IVIUDFS, and a search of the Microsoft knowledge base was negative. What fascinates me is that other machines are reading it.

For a work around, copy the files to the hard drive of a machine which will read it, then burn a new cd, Do not do a copy CD, or you will copy the problem as well and end up with the mystery format on the new CD.

You probably need a UDF driver to be able to read CD-ROMs that use the UDF format. This is often included with CD burning/utility software.

Not in my experience. As you note, InCD is Nero’s UDF format, but it’s not restricted to CDRWs. Just like Adaptec’s DirectCD, you can finalise the CDs.

The disc was burned with Nero or Roxio as far as I can remember.
We use Nero on all the home computers, and all but my Monster can read it.

Tried that, but it still says the same freakin’ format.

I am getting seriously pissed.

I used my husband’s computer which had some Sony burner on it that I’m not familiar with, but is real user friendly.
Went to make a data disc and it said ‘hey, you should format the CD’ so we did.
I added the files from the copy I made to the hard drive (I had made a folder titled ‘program’ on the Desktop and just copied all files into it).
They added to the new disc fine and then it said ‘want to make this compatible with all computers?’ and I said, ‘hell yeah, that’d be real nice’ so we did.
Took the freshly burned disc, inserted it back into my computer and it still comes up in that same flipping unreadable format. :mad:

I put back in my Nero 6 Memorex Suite CD and even though I had fully installed everything from it earlier, I tried installing the InCD and a few other things again as I don’t see them in the Program menu (matter of fact, still don’t). Still nothing.

I found a UDF driver from download.com but it says it’s not compatible when trying to install (doesn’t list XP as supported, even though other XP users posted that it worked for them) and just has the option to ‘close’.
ETA: I’m trying to narrow down the search on download.com to ‘XP specific’ but the search engine is being a real donkey right now and is giving me nothing. Perhaps it’s just too busy at the moment. :frowning:

I just looked at some other sites and I get the same thing - drivers for everything BUT XP. I try another one and it says ‘you’re running Windows NT & it can already read this type of file’. I tried installing anyways and nothing.

I’ma cry. :frowning:

Why not burn the files straight to the CD as Tracks rather than faffing around with InCD and UDF formats.
All you want to do is install the data - correct.

Burn it as a track that ANY CD-R can read rather than as a strange format.
You already have it on your husbands PC, burn it to disc as a track and be done with it.

That’s because WXP has a built-in drag&drop CD burner (though depending on the disc and brand of disc, it may HAVE to be empty if it is a CD-RW)

I’m assuming you already tried that, right?

When I upgraded from W98 to WXP, ALL my CD burning programs became useless.

I’m not trying to ‘faf’ (faff?) around with InCD and UDF formats, except as suggested to try to get it to work. I’ve tried installing and burning the discs, SOP, as I’ve done many times. I’m not selecting a format (not given the option!); just made a data disc which is how I’ve always made my copy/backups that have always work.

Please explain about the track thing, because I did burn it to another new CD that supposedly any computer can read (as stated in the post right above yours) and it’s still a no-go.
I’m not ‘burning it in a strange format’. The program to burn on hubby’s computer (Sonic, not Sony btw :rolleyes: ) just gives me the same options as Nero: Data disc, Archive disc, or Backup disc.
You add the files and burn it. Nothing about track options. But even if there were, it is having a problem seeing anything on any disc in that format (i.e. the 3 copies of the program I now have :rolleyes: ) so I don’t see how making it a track would make it read it. But I’m no techie so some advice/walk-through would be helpful as I would love to ‘be done with it’.

scottkris, the disc is most definitely a CD-R and don’t assume nuthin’. :o
How do I try the ‘built-in drag&drop CD burner’? :confused:
My husband built this computer and it has installed the program fine on every OS & co. re-installation except for this last one after he added the extra drive, RAM and video card. Perhaps it is an option I need to enable or install from the OS disc that he skipped or changed for some reason this time?

Again, thanks to you guys for your time and patience. :slight_smile:
