Possible disc controller issue

My G5 is randomly freezing. Sometimes it will remain partially responsive (i.e. I can switch between apps), but the moment I do anything that require disk access I get the beach ball. Eventually everything grinds to a halt. Other times It simply locks up.
Furthermore, when I try to reboot I ofter have to try multiple time before it successful reboots. Some times it doesn't recognize my hard drive and all I get is the flashing question/folder. And sometimes it starts booting but gets stuck at the "??something after 1 tries line." Typically, I'm able to resolve the situation by going in and reseating the SATA cable that connects the drive, although, it can take multiple tries (or at least this appears to help).
Now a bit about my setup. My boot drive is a 150GB WD Raptor connected through one of those cheap internal/external SATA cards OtherWorld computing was selling a couple of years ago. At the time I wanted a WD Rapter, but there were reports of incompatibility with the onboard SATA so I got the card offered by OWC. And for a while there were no problems, I could run my computer for weeks at a time without rebooting. However, things have deteriorated so that I'm being forced to restart in the manner mentioned above once a day on average.
Does anyone have any ideas what's causing this? Is there anything I can do to avoid/bypass the problem? I suppose I could try the onboard SATA, but I'm holding off on doing that since I don't want to frag my drive. (Although I do have the TimeMachine backup plus a CCC backup.) The only other thing I can think of doing is replacing the SATA card, but that's a $100 expense I don't really want. And this is assuming my assumption of a controller based problem.

Well I went ahead and switched to the built in SATA controller for my boot disk. I'm now at 8 days up time. Considering that before this switch I was having daily freezes, this is a major improvement. I've had at least 1 crash since I made the change two weeks ago, but at the moment I'm pretty certain that the solution to my problem is to replace the SATA card. Any suggestion for a cheap SATA card?

    I do get the same problem. It believe it started after I switched from HDD to SSD some month's ago. My machine is very fast now so I do not have performance problems (only a very slow power on boot).
    The description above is exactly the same as I have.
    Does somebody has the same problems?

  • 890FXA-GD65 and possible USB Controller related issue?

    Hi all - Been having a bad time of it with a new system build for a little under a month now.  Have tried to capture my "notes" below, any idea of a root cause?  Is anyone aware of known issues with the board; the board and Windows 7; the board and some other component(s)?
    My issue:  During Windows 7 x64 installation or startup, the system will freeze at the "Starting Windows" screen.
    My system specifications:
    MOTHERBOARD: MSI 890FXA-GD65  (BIOS ver 18)
    CPU: AMD Phenom II X2 555 @ stock speed  (HDZ555WFGMBOX)
    MEMORY: DDR3 1600 2X4GB G.Skill Ripjaws-X [DIMM1 & DIMM2] (F3-12800CL9D-8GBXL)
    VIDEO CARD: XFX Radeon HD 5670 512MB (HD-567X-YNF3)
    HARD DRIVE(s): 2 x Western Digital 500GB 7200 drive (WD5000AAVS)
    POWER SUPPLY: Antec NEO ECO 620C 620W
    Windows 7 x64 (Ultimate edition, retail)
    This problem has existed since I first built the system and is consistently reproducable.
    I am able to avoid the issue by disabling the USB Controller in BIOS prior to initiating the Windows installer.  This will allow me to proceed through Windows installation, but as soon as the USB Controller is enabled once again, the issue recurs.  Having to disable USB support is undesirable.
    I'm now on my second 890FXA-GD65 motherboard, having RMA'ed the first board after a fairly brief exchange with MSI tech support(2 replies, with the eventual suggestion of RMA for a faulty USB controller).  So I went through the RMA process with the online retailer, receiving a new board today.
    The problem is that the RMA replacement behaves in exactly the same manner.  Normally this would suggest to me that the problem may lie with one or more of the other components, but I've not been able to identify issues with any of them.  One obvious suggestion would be to try swapping out components, but my resources are constrained on that front - video card happens to be the only component for which I have a alternate that I can test with, actually.
    As far as troubleshooting investigation, here's what I've done/observed:
    1. Windows installation/startup will succeed if the USB Controller is disabled in BIOS.
    2. The same behavior can be observed with a Windows Vista installation disk as well.
    3. When loading Windows in safe mode, the last driver file loaded was disk.sys
    4. Memtest86+ (v4.2), repeated full passes reveal no issues with the system memory.
    5. While seeming that it would be an unlikely factor, I have swapped out video cards(to an eVGA 8800 GTS 320MB), but observed the same issue still exists.
    6. Running in a single DIMM configuration affected no change.
    7. Have disconnected one or the other of the hard drives with no change.
    8. The BIOS version installed is equivalent to the latest(and only) version posted on the MSI support site.
    So...any ideas on what's left to try?  I've done enough reading online to notice that I'm not the only person to have observed this behavior, but have yet to encounter any explanation of it nor a resolution.
    Any suggestions?

    Trying to catch the points that weren't explicitly spoken to by me in the last attempt:
    @Stu - Regarding testing with zero USB devices connected - this was done as part of troubleshooting and it has no observable effect, so I think that I can rule out a bad USB device being the culprit and I apologize for not making that clear previously.
    @Frederik - I've done a little more legwork on the memory item.  Troubleshooting, for the most part, has been executed with this memory set to run as DDR1333 @ 1.5V as that is what the board auto-defaults to(the kit is rated as DDR1600 @ 1.5V)  It was at the defaulted setting that I ran memtest86+ and no errors were reported.
    I've also just now made an attempt to run this memory as DDR1066 at 1.65V and still there is no change in results.  In my research on this specific kit, I have not run into accounts like mine - in the accounts that I have read regarding a poor experience with the kit, memory has either been been obviously bad, for which failures are reported in diagnostics like memtest. ...or, I suppose that there's also the random guy complaining about his overclock not working or the memory speed defaulting to the wrong value in BIOS. 
    Frankly, I don't want to battle any particular component and I owe no allegiance to this make of memory.  I do want to try to be objective, given that I'm stuck with these modules until I make the decision to RMA.  As such, I had read what info is available out there - prior to purchase, I hadn't noted so many reports of issues with this kit across a considerable sample size of feedback so as to cause me initial concern, or else I would have gone with a different kit/different brand.  Probably will do that anyways, next time, but in the meantime, I'm afraid of this being a distraction.  If both myself and this other person(drgan) had both been using the same memory kit, and thus it was more likely to be the common thread, I'd certainly be more inclined to this line of reasoning.  But since he's using Kingston and in the few other accounts of a system freezing on USB controller enabled status I've noted varied memory kit brands, it doesn't seem to me to be an obvious culprit.  But if not, then what's left to consider?  The other interesting factor to me is that the issue appears to be Windows-centric....but... 

  • LWAPP won't joint controller. Possible US/Mexico Issue

    I have some LWAPPs in Mexico that will not join a controller set to MX country code until I first join them to a US controller, let it update the firmware, then join them to the MX controller. Is this normal? It seems very inefficient to do it this way. Any help would be appreciated. Thanks, Dan . . .

    Hi Dan,
    No, this doesn't sound normal at all. I have not worked with AP's in different countries (Canada only :) but it sounds like you have some sort of mix and match between Country codes on the AP's vs WLC. Maybe you could look into what Country Code is set on each WLC. In WLC 4.1.171.1 and later you can set the controller for Multiple Country Codes. Maybe this would help;

    Multiple country code support-This release allows you to configure up to 20 country codes per controller. This multiple-country support enables you to manage access points in various countries from a single controller. This feature is not supported for use with Cisco Aironet mesh access points.

  • Possible Hard Drive Issue?? How to test?

    I recently upgraded to Leopard this weekend, seems to be running "snappy" in some parts, but I might have an issue with HD possibly reading slow. Sometimes when I do certain functions (open certain files or programs) I get beachballing. This is the same issue I had in Tiger on the final 2 months I had this PB. For the years I have owned this PB I only started to have this beachballing within the last two months. It starting after a bad crash in Labor day (it was stuck on beachball for 3 days while I was out of town) at first the PB could not see the internal HD until I did a matter of things with installing Tiger on a external HD, resetting everything. Once I was able to get teh HD to show up as a device installed in the computer I recovered the files and zeroed out and formatted. From that point I had the beachballing and audible click of the HD (which I never had before). I know the clicking is indicative of a dying hard drive, yet upon zeroing out and reformatting i get the beachballs and the drive has passes the disk verify and all the SMART tests I have tossed at it. I also have checked out the Console and have not seen a single IODATA error string of anytype. I did notice when I installed Leopard it took over an hour and a half and the same with WoW (possibly longer, I was AFK per disc), however on transfering data to the external HD and over the network seems like access speed is fine. With activity monitor up, it's telling me that I have about 247megs of free ram available to the system at most times. Can anyone recommend anything I can test performance and some numbers I can look at to compare? I would hate to spend money on a replacement HD and find out the actuallty controller was defective and that all HD's would act in this sluggish manner.(HD install is the original Hitachi 60gb, 4200rpm). Possible replacement HD would be a Seagate 120 5200rpm.

    jammer:
    You have the original HDD, which is the slower HDD. You also have what might be a failing HDD. (The only surefire result on S.M.A.R.T Status is a Failing grade. Verified means that it is OK at the moment, but can't promise you anthing.)
    Here's what I suggest:
    1. Make sure your RAM is maxxed out.
    2. Install a new HDD. Whether 5400 rpms or 7200 rpms, you will notice improved performance.
    3. Be sure you have an up-to-date, reliable backup (clone to an external firewire HDD), especially if you keep the old drive, but you should anyway.
    4. Put your old (removed) Hdd in a firewire enclosure and use it as an external HDD.
    Please do post back with further questions/comments.
    Cheers

  • Controller Issue? or Journaling issue?

    Hello all
    I've been having this weird problem with an Xserve RAID and a couple of servers. I've been narrowing down the problem but i want to get some outside input on the matter.
    I have 3 Xserves, 2 connected to the Xserve RAID (DAS). The problem seems to happen at random, but always starts with the same xserve. The problem seems to be a hardware issue, form what i can see in the logs, the tricky part is identifying the piece of hardware responsible. Here are all the clues i've been gathering:
    Problem starts with
    kernel[0]: jnl: disk0s3: flushing fs disk buffer returned 0x5
    Sometimes followed by
    kernel[0]: ASP_TCP CancelOneRequest: cancelling slot 0 error 89 reqID 1 flags 0x9 afpCmd 15 so 0x1006ecc0
    And then the horrible
    kernel[0]: disk0s3: I/O error.
    kernel[0]: jnl: disk0s3: dojnlio: strategy err 0x5
    kernel[0]: jnl: disk0s3: writejournalheader: error writing the journal header!
    kernel[0]: disk0s3: I/O error.
    The inevitable screams from the services that depend on that volume follow
    imap[3899]: IOERROR: opening /Volumes/Userdata/spool/imap/user/jcarrillo/cyrus.header: Input/output error
    This causes AFP to stop and also imapd, both of which have their working directories within that volume. These are disks 8-13 in one hfs+ journaled volume in the raid.
    At first we thought the HBA's were the ones misbehaving, but after swapping slots and swapping servers, the same server is the one failing us.
    This error doesn't make the server unresponsive, only processes or actions that involve reading the volume, hang, that includes a simple ls in /Volumes or diskutil.
    We've already fsck both disks with no red flags. Here's the diskutil list
    diskutil list
    /dev/disk0
    #: TYPE NAME SIZE IDENTIFIER
    0: Applepartitionscheme *2.3 Ti disk0
    1: Applepartitionmap 64.0 Ki disk0s1
    2: Apple_HFS Userdata 2.3 Ti disk0s3
    /dev/disk1
    #: TYPE NAME SIZE IDENTIFIER
    0: GUIDpartitionscheme *76.3 Gi disk1
    1: EFI 200.0 Mi disk1s1
    2: Apple_HFS hd 76.0 Gi disk1s2
    I will be performing the Apple Xserve Diagnostics later tomorrow to discard server side hardware, but i am inclining towards a raid controller malfunction. Anyone seen something similar?
    AFAIK there is no xserve raid diagnostics from apple, is there a third party tool? Or is it just a replace component thing and hope for the best?
    Anything to help me be sure to blame the controller will be greatly appreciated.

    You're only reporting logs from the host system. What about the logs on the RAID itself?
    This sounds to me like a problematic array - possibly caused by a faulty disk. RAID Admin should give you some insight as to whether that's the case or not.

  • Adobe Encore 1.5 DVD disc reading issues in DVD Duplicator

    Hello All,
    I'm wondering if anyone has ever had the experience I'm having and if they might have a solution. I produce a weekly 1 hour music video program for public access cable TV. The show is bicycled to 15 different locations on DVD. I use Adobe Premiere and Encore the capture, edit and burn the completed program to DVD. I recently purchased a DVD duplicator tower (1 to 5 disc) to speed up the time it takes me to make the 15 copies I need. However, I have encountered an issue that I believe is related to Adobe Encore 1.5; when I put the completed master DVD into the duplicator, the duplicator is unable to read the disc. I know the disc (discs - I've tried several different shows on different DVDs with different types of blank DVD brands) is playable in the PC and on several standalone DVD players. Also, we get no complaints from the 15 stations that play our discs. At this time I'm stuck making 1 copy at a time in Encore. I know that the duplicator works as I have been able to test and successfully duplicate other DVDs and CD's that are not copy protected without issue. Has anyone encountered a similar issue? If I need to provide more information let me know?

    Some notes/ideas here that may help
    To
    Burn Error Proof DVDs (Well, close to error proof!)
    Use the SLOWEST possible burn option your burner will allow in Encore, since it is much better to take a bit more time burning the disc than it is to burn "fast" and have a disc that won't play
    Set the VIDEO portion of the transcoding options to a Maximum of 7,000 so your burned disc will have a better chance at playing in desktop players (which support burned discs, if at all, only as an "after thought" of the DVD specification)
    Use AC3 or PCM audio transcode settings for best player compatibility (some discussion of MPEG audio not being supported by all players, especially for NTSC discs)
    Buy and use Taiyo Yuden (or Verbatim?) brand blank discs

  • Dying to buy iMac ... disc scratching issue scaring me off

    Hi, tossing this question out here, also have done so in other forums. I need to replace our main desktop computer at home. It's a PC. However, I've used a Mac for about 17 years or so at work, currently a 27-inch 2.66 ghz Intel Core i5 iMac, so I have knowledge of "both universes."
    I'm dying to get an iMac for home use, the 21.5-inch model (that will suit my needs at home, don't need a 27). I don't think PCs are crap, I just like Macs better and would like to totally dive into the Mac pool and be in the same universe both at home and on the job. I've been telling my wife, whose only computer experience has been with PCs and has been resistant to make the change, for years that if she ever got her hands on a Mac, she'd never go back, and she's finally amenable to trying.
    I've been shopping around and had about decided on a refurb from the Apple Store ... when I came across the issue of the superdrives in iMacs scratching discs. And, on reflection, I think it's happened a few times with my iMac at work. I've brought some personal discs to put things on iTunes and later noticed scratches on the discs, and I'm quite anal about keeping discs in pristine condition.
    I know I'm a Luddite in the era of "the cloud," and that probably within a decade or so recordable media like CD-Rs and DVD-Rs are going to be about like VHS. But in the here and now, in my personal computer usage at home, I still do an incredible amount of disc usage and disc burning.
    I do to the point where this is scaring me off, because having the drive scratch discs really is a deal killer for me. I've read the stuff at various forums about how you have to take the discs out just a certain way, but the human reality is you're not going to do that 10 times out of 10 (plus other people, including kids, would be using this computer at one point or another and it will be impossible to guarantee that they do it right 10 out of 10 either). I've read about people taping up the slot and using a Dremel to burr the aluminum down, but I'm not inclined to do that to something I'm going to spend so much loot on. I'm also not inclined to spend that much on a computer and plug an external burner drive into it.
    This is my question ... this issue apparently was very prevalent on the 2010 iMacs. I've gotten mixed information on whether it was fixed in the 2011 iMacs (most of the refurbs available at the Apple Store are 2011 models). Would I be less prone to have this issue by spending a little extra and buying a new, recent production iMac as opposed to a refurb?
    I know I seem to be dwelling on an issue that might be inconsequential to some folks, given the other advantages to a Mac. But again, I use recordable media so much, and some of the things I have on recordable media that I often insert into my computer to do things with are so irreplaceable, to where really any chance of this issue happening is, as I said, a deal killer.
    Thanks in advance for any help.

    My late 2009 21.5 scratches discs. There's a long thread about this. The sharp rear facing metal edge of the slot seems to be responsible. Even inserting a disc with extreme care, keeping the label side as much as possible towards the front, doesn't always prevent this from happening. But maybe the current models fixed this. Don't know.

  • MSI K7N2 Delta ILSR Questions & RAID Promise FastTrak Controller Issue

    I have recently rebuilt my system replacing the MSI KT3 with an MSI K7N2 Delta. I have been impressed with the features and stability of the system, however, I have some questions that I hope some of you that have more experience of this board can answer:
    1. I am using the AMD Athlon XP 2200 (and all the other components including the Lian Li case) which I was using on the KT3 board. The CPU temperature is around 45 degrees C but on the KT3 it was only 35 degrees C when idle. Any ideas ? The heatsink is definetly mounted properly. The temperature did drop by 10 degrees C when I flashed the
    BIOS to fix the known CPU temperature issue but I think its still high.
    2. I do not have any serial ATA devices or anything connected to IDE3 channel and during the BIOS boot up I get the message:
     "No drives attached to FastTrak Controller. Bios Not installed."
    Is this correct ? Should I be getting this message ?
    I would like to disable the onboard Promise Controller since it is taking up resources and it slows down the boot speed (although only slightly). The MSI website says that the onboard RAID controller can't be disabled. I think this is poor design. Does anyone know if this is going to be addressed in future BIOS releases ?
    3. Which of the USB ports are USB 2.0 and USB 1.1. I thought it was rather strange that only 2 of the 4 ports on the header actually active.
    Many thanks for your help.
    Rupesh

    First off your temp is ok on that board. If you have not loaded the onboard raid driver do so and it is something you have to suffer with on the MSI board. All of your USB ports should run at USB 2.0 and you also should be able enable all of them in the bios.

  • Archive and Install/Disc Utility issues -

    I'm currently spending a summer abroad in South America, and have had issues with my Macbook Pro (early 2011 version) no longer starting up after some virus experiences last week.  The computer hangs itself during loading on the white screen w/ grey apple and the spinning dial.  In contacts with Apple Care as well as some Mac-saavy friends, the following situations have been tried:
    Opening in safe mode - The loading bar (added at the bottom of the grey apple screen) loads about 1/4 of the way, disappears, and the computer hangs itself.
    Opening in single user mode - I run the recommended sbin/fsck -fy command to clean up the hard drive.  It comes back after having checked 6-7 parts, saying that the MacHD is in good shape, with a message following saying that something had been "modified" (forgive me for not remembering the correct verbage at present).  I then run the same command again, resulting in a message that the HD is clean and without error.  I then "reboot" and remain hung on the white screen w/ grey apple.
    Opening in verbose mode - I reach the following lines of text, and then there is no further progress:
    enable
    IONetworkController::enable
    createMediumTables
    enable end
    MacAuthEvent en0   Auth result for: 00:23:cd:1e:f2:c4 No Ack
    same line as above saying "Auth timed out" at the end
    Command+option+r+p - shock two or three times, (three startup chimes) and computer continues to hang itself in the normal spot.
    - So, at this point I took the advice of Apple Care and a few other friends, and tracked down a "retail copy" of Mac OSX (10.6.3) in order to try to do an Archive and Install or any sort of Disc Utility via the startup disc. 
    Inserting the disc and holding "c" at startup results in the cd drive whirring the disc for a few moments, and then remaining hung at the same white loading screen.
    Holding "option" during the startup gives me the option of loading from the HD, or the disc.  Selecting the disc proceeds to whirr the cd drive, take me to the white loading screen with the grey apple, and... you guessed it... leaves the CPU hung.
    My question is then, is my Macbook Pro unable to read this disc and execute Archive and Install/Disc Utility for hardware reasons as per the virus attack, or is the disc not compatible with my version of OSX (which I have since confirmed through my wife to be 10.6.6)?
    Different sources have told me different things.  The local AASP in Uruguay sold me what they professed to be the "latest" version of OSX - the 10.6.3, what's more for $55 dollars instead of the lower cost as available in the states (between $15-$30), so I am reluctant to go back to them for advice when they seem more inclined to cash in on my inexperience (Mac owner of less than a month) than actually fixing my issue.  Apple Care told me that a standard "retail disc" should work, but I am assuming now that they believe I can snag the same version as initially came with my Macbook Pro.  Should I be looking to have my wife mail my original OSX install DVDs down here to resolve this problem?  Should 10.6.3-retail be working and is not for reasons I haven't identified?  I have since done some online research and found mentions that doing any sort of HD partitioning or OSX reinstalls can only be accomplished by utilizing a disc of an equal or more recent version of the OSX (examples that 10.4 can't work on a notebook preinstalled with 10.5, etc).  Does this translate to 10.6.3 not being able to function for my 10.6.6 MBP?
    Any insight or thoughts would be much appreciated, as essentially all of my schoolwork and assignments are now trapped on an inaccessible HD.  Thank you for your time.

    I tried adding in a bunch of information about what your troubleshooting steps meant, but the server went into maintenance while I did. So, here it is again:
    "Opening in safe mode - The loading bar (added at the bottom of the grey apple screen) loads about 1/4 of the way, disappears, and the computer hangs itself."
         This is FSCK running, and gives you an indication of it's progress.
    "MacAuthEvent en0   Auth result for: 00:23:cd:1e:f2:c4 No Ack"
         This is either a failed DHCP request or ARP request.
    "Command+option+r+p"
         Command+Option+P+R - Resets PRAM. That's why p+r.
    "Inserting the disc and holding "c" at startup results in the cd drive whirring the disc for a few moments, and then remaining hung at the same white loading screen."
         This problem indicates that the disc is too old to boot your system. The reason for why this disc cannot boot is because it doesn't contain the necessary drivers for your model MacBook Pro. My mom and brother have similar models, and my brother had similar issues while in Japan. He went and got an install disc as well, which failed, I ended up stepping him through so that it would boot in Safe Mode, and then got it working in Normal Mode remotely.
    FYI: Sophos has a free Mac Antivirus program, that is very processing friendly, and will scan in the background. You may wish to consider it as an alternative to Avast! if it continues giving you problems. Though I suspect it may be coincidence that your computer had problems shortly after Avast! cleaned up files. Let me know how it goes. You may wish to open up Disk Utility and check your S.M.A.R.T. Status. You want to make sure it says "Verified" If it doesn't say "Verified" then you have a problem.

  • PS crashes in Windows 7.  Possible windows explorer issue?

    Hi,
    I have an intermittent but annoying problem.  Basically, when I use the "Open" dialogue box to access a new file CS4 will hang, shutting down completely.  The same issue has occured when using the "Place" command.  It doesnt seem to happen when using Bridge to open files. A possibly related issue is that although this does not happen every time it does seem to come in spates and when it does CS4 automatically shuts down the automatic advanced openGL functions (i.e. no revolving my screen dynamically while drawing which realy IS a pain as I am an illustrator and this function was a major draw to upgrading to CS4...)
    Does anyone have any advice on how I might resolve this?
    Thanks in advance!

    You either have to physically delete (or rename) the preference files or, if using the Alt, Ctrl, and Shift method, be sure that you get a confirmation dialog.
    This resets all settings in Photoshop to factory defaults.   A complete uninstall/re-install will not affect the preferences and a corrupt file there may be causing the problem.

  • Mac 10.5.6 Upgrade - Disc Image issue, as downloaded on a PC for my Mac

    Hi,
    I would like to upgrade my Mac OS (currently on version 10.4). I use dialup internet and so I cannot download the update onto my Mac, through dialup.
    However, I have gone to my brothers house and downloaded the update onto his PC laptop, which I then saved onto my mobile (as data storage).
    I am now trying to open the disc image onto my Mac (after saving to the Mac, from my mobile phone) but it comes up with an error message saying:
    Warning
    +The following disk images failed to mount+
    Image
    MacOSXUpd10.5.6.dmg
    Reason
    +no mountable file systems+
    Can someone please tell me what the problem could be? Is it possible for me to download the update onto a PC and then move it over to my Mac, and it will work?
    Many thanks!
    Paulina.

    the disk image must have gotten corrupted somewhere along the way. You'll probably have to redownload it. also, I'm not sure you understand this but you first have to buy and install leopard on your computer. then you can install leopard updates like 10.5.6. you can't install 10.5.6 combo update on a tiger system like yours. You must have some version of 10.5 already on your system.

  • Dual Disc-ITUNES issues

    Hi! Could someone possibly tell me what I'm doing wrong here? I have a dual disc cd (the cd/dvd discs) and am trying to figure out why it is that ITUNES isn't recognizing the disc. I have tried taking the disc out then putting it back in, restarting Itunes, and was wondering if anyone could tell me what I'm doing wrong. I know I am not great with a computer, but I didn't think I was THAT ********...
    Thanks,
    R

    Ok, obvious question first. You are asking iTunes to recognize the cd side and not the dvd side aren't you? Do you have a dvd drive you can try?
    Are your normal cds recognized ok? I don't have any of these dual discs, but I have read in some audio publications that there are a few problems with these discs not being read in audio cd players either (and some high end ones at that).
    I should also point out that you'd get a better response to this question if you posted in the iTunes forum.

  • Disc Burning Issue

    I've been burning discs forever but suddenly I have an issue. I'll place a new disc into the drive and I get the usual box that states, "You inserted a blank CD. Choose an action...blah blah blah". I click OK and move onto my Burn Disc Folder. When I click Burn I get a box that says insert blank disc. So something is not clicking there. I hope this doesn't mean I need to buy another disc drive.

    cvanlindt,
    The drive is probably Ok. To test, wait to insert the blank disc until after you have clicked burn and it asks for a blank disc.
