Does anyone know what this means? I've already posted a thread about a similar problem with burning DVDs, but then they worked for quite a while. Now I'm having problems again, & getting this message:
'This disc can’t be verified and might be unreliable. Try again using a new blank disc (error code 0x80020063).'
This has happened with about half the DVDs in a batch of 50; they cannot all be faulty!
Thanks
iMac, Mac OS X (10.7)
What brand of DVDs are they?
Verbatim, DVD-R; I seem to recall these being recommended for Macs!
Indeed they are!
If you have a firewall, turn it off. If you have Time Machine, turn that off as well. Restart.
Post back!
Ok, thanks. I'll have to try this later as I'm working right now so don't want to start turning the computer off & on. Why would Time Machine mess up DVD burning?
I have no idea, but it has been reported as doing so.
Also, don't forget the low burn speed of 2x or 4x.
Sometimes something like the Sony Rootkit may be to blame. If your iMac is older than October 2011, you should be able at minimum to partition your hard drive with Disk Utility without damaging it, as long as there is at least 15% of the hard drive free and set up 20 GB to install 10.6 on. Use the 10.6 installer disc that either came with your Mac, or a newer 10.6 retail release. March 15, 2010 was the latest release of 10.6.3. Once installed, boot off 10.6 using Apple menu -> System Preferences -> Startup Disk and see if the burning works better there. Don't ask me why, but even without recognizable rootkit extensions, the ability to read and burn discs on 10.7 or later is damaged on some Macs. If your Mac is newer, you may need to try to install 10.6 Server as described here:
https://discussions.apple.com/docs/DOC-6841
Strangely enough virtualizing windows does not work as well as running 10.6.
Another possibility is the fact that spindle bundled DVDs and CDs can get damaged fairly quickly on a spindle. It is important to store them in their own individual envelope or jewelcase as soon as you buy them, to ensure they remain good. If you bought these as jewelcase discs, then obviously this doesn't apply to you.
Thanks. They are on a spindle; I didn't know this. But what a pain; having to put 50 or 100 disks into individual cases!! I don't have this sort of time to spare; why are there always these obscure problems with Macs that never occur with Windows?..! (I often ask myself why I bought this Mac; it seems to create so much extra work...).
Re. your first message; I don't really follow all of this, sorry, but you seem to be suggesting I install an older version of the OS? But won't this wipe everything off the hard drive to zero so I have to start again from scratch as if the computer was new again? That sounds like a complete nightmare. (My Mac has OS X Lion version 10.7.5.). That is outrageous if Apple is selling computers that are effectively faulty! Why did they not do a product recall if such an essential feature as disk reading/writing is faulty?
NB: I just managed to burn a DVD -R without any problems this time; then I tried a DVD -RW - and the same problem occurred - it tells me the disk is 'locked', but when I go to 'disk info' I cannot unlock it as it's greyed out.
The Rootkit problem is a problem in Windows just as much as the Mac. You can read more about it here:
http://en.wikipedia.org/wiki/Sony_BMG_copy_protection_rootkit_scandal
For whatever reason, 10.6 is not as sensitive to it as 10.7 or later.
But won't this wipe everything off the hard drive to zero so I have to start again from scratch as if the computer was new again?
No. Partitioning on Mac OS X 10.6 and later is allowed if you have sufficient free space. Just run it while booted into the Mac normally from Disk Utility in Applications -> Utilities. It is recommended of course you backup your data before you begin as a marginal hard drive could fail anyway.

It is not Apple's fault that Sony messed up everyone, including car CD player manufacturers when putting the rootkit on its music CDs along with the BMG.
And the issue happens, on random machines, some have no trouble whatsoever. It is very difficult to issue a recall, when the issue entirely random and impossible to isolate. This issue has been present not only on Apple's computers, but PCs as well.

Follow these directions to rewrite:
Disk Utility 12.x: Erase a disk, CD, or DVD
Note, only DVD-RAM offers hard disk like rewrites, where you can choose what to delete and write over.
Both DVD-R and DVD-RW also offer write multi-session mode, which doesn't allow you to write over the same data that had already been burnt, but rather allows you to burn tracks that have not yet been burnt. That's documented here:
Disk Utility 12.x: Record on a recordable CD more than once
The error code can be the Sony issue, it can also be dust in the drive, it can also be due to one of the items documented on my FAQ*:

Thank you very much for all of this information; I do appreciate it! I will have to look at it after the weekend as I'm working now & about to get a train somewhere; thanks.
I had the same Problem . Using Tesco DVD's . Tried several fixes in the discussion.With no success . But Changing to Polaroid DVD's solved the problem . Worked straight away . Hope this helps
