Windows unable to load isStor.sys from floppy after pressing F6 when installing

Basically after pressing F6, then pressing S to specify the RAID divers I want, windows will read the floppy and inform me that the drivers supplied appear to be newer than the one on my windows CD and asks me to either use the ones on the floppy or the ones on the CD. After making either of these choices the computer continues to load the drivers then offers me the option of how to install windows and make partitions etc. Once the drive is formatted it tries to load these drivers again but gives me the message saying "Cannot copy iaStor.sys" press ENTER to retry or ESC to skip. If I choose to SKIP I get a similar message about iaStor.inf and iaStor.cat. If I skip all three of these files, (there is no other option because if I keep pressing ENTER to retry, I get nowhere), it will copy all the other files it needs but I eventually get a BLUE SCREEN OF DEATH.
I have 4 identical SATA2 hard disks I want to set up as RAID. At the minute the only way I can get my computer to run is by having the drives set up as IDE drives. Which totally defeats the purpose of buying SATA2 drives.
Has anyone got any ideas, please.

Hi,
Thank for the replies.
Got the problem sorted. The problem was it read the floppy on the first instance when you press F6. I was then able to select the drive I wanted to install windows on, and it would format the disk. Then it would look for the files again when installing windows. I discovered that it was the copy of windows I was using that was at fault. I was using a SLIPSTREAMED version of windows and the files needed must have been missing or corrupt. So I just reverted back to using a standard version of windows and all is OK. Got my RAIN up and running now.
The other problem I seem to have now is that when I insert a disc into my DVD drive it cause the system to go a bit slow, the mouse would stutter on the screen when I try moving it and would sometimes not move until the disc had stopped spinning. I have two DVD writes attached to the 40 pin IDE connector on the motherboard. This connector is controlled by the JMICRON chip. In the BIOS I have it set up to act as IDE and not RAID. I had initially just let windows pick up on this device and it installed it's own drivers, but I remember someone on another post saying that if you install the JMICRON RAID drivers from the motherboard driver disc it might make thing better. but it hasn't.
Any suggestions????
Thanks,

  • ITunes was unable to load dataclass information from Sync Services

    Hi,
    I have Iphone 3GS with the latest version 3.1.3 and iTunes 9.1. After i uograded my iPhone to the latest version i am not able to sync with the iTunes and receive the message "iTunes was unable to load dataclass information from Sync Services, Reconnect or Try later". I am using Windows XP with Symantec Endpoint protection.
    I have tried following steps to troubleshoot the problem but all my attempts have failed,
    1. Uninstall iTunes by Removing, iTunes, QuickTime, BonJour, iPhone congiguration Utility and Bonjour. Remove all the iTunes and related folder from the C:/ drive
    2. Restart the computer and intall the latest version of iTunes and Quicktime
    3. Restore the iPhone to the factory settings using iTunes
    4. Restart the system as well as hard Boot the iPhone (Hold Start and Wake/Sleep Button)before connecting again
    5. Repeat the Steps 1 and 2 after restoring the iPhone
    I am still getting the same error and now I can't even open the first page for iPhone in iTunes when I connect it to my computer. All my content is still in iTunes but everything is lost on the iPhone.
    I searched the Apple support and they talk about problem with the Symantec Endpoint. I have the latest version of Symantec endpoint way above what is mentioned on the Apple support page.
    Can someone please help me, it seems restore worked for most of the people facing this issue, but for me even restore is not working.

    I got a present of an itouch. This is my first time back to apple after 5 years. I cant get my itouch to sync due to dataclass error on Windows XP pro. I have installed the latest version of itunes 9.2.1.
    WHAT IS THE POINT IN OWNING A DEVICE FOR PLAYING MUSIC WHEN YOU CANT LOAD THE MUSIC !!!!!
    Does anyone have a solution or alternatively (shock horror) Apple could actually get its AR*E in gear and fix the problem. I would also suggest that Apple would post a friggen solution on its website, but no that may be too much to ask.
    very frustrated. any help gratefully received otherwise the touch gets thrown out.

  • ITunes was unable to load dataclass information from Sync Services-Solution

    Hello all. I recently upgraded to iTunes 9.1.1.12 on a laptop with Windows XP Pro and the latest iPhone OS (as of May 16,2010). Right after that, I started getting the "iTunes was unable to load dataclass information from Sync Services" error message. After I dismissed that window, it would go ahead and indicate that it was synching for a minute or two, and then indicate (in iTunes) that it was backing up the iPhone. This will run forever unless cancelled and the phone would not synch.
    After reading various solutions that worked for others (install Mobile Me, reinstall itunes, run diagnostics, all with numerous reboots in between), this is what worked for me:
    1) Open up Windows Services, and stop the Apple Mobile Device and iPod Service, and mark them as manual (as opposed to Automatic).
    2) Deinstall iTunes
    3) Delete the c:\program files\common files\apple folder (and all sub folders within). This is where the services are stored, and when I did all of these steps without doing this step, it didn't fix my problem. By deleting this folder, you insure that the iTunes install reinstalls these. You should see the services that were stopped in step 1, running again after the install is done. Note: I don't use Safari or QuickTime on my laptop, so I can't say whether or not this step would have any impact on those apps.
    4) Reinstall iTunes.
    5) Connect the iphone to your computer.
    6) At this point, I still got the dataclass error, so I immediately cancelled the synch.
    7) Run the diagnostics for the iphone (connectivity and synch).
    8) At this point, two DOS windows launched, and I did get another error about being able connect to the synch server.
    9) Closed the error message and disconnected the iphone (the phone at this point did not indicate that a synch was occurring).
    10) Reconnected the iphone and, voila, it's been working fine ever since.
    Hope this helps someone else out until Apple deals with the 9.1.1.12 (and .11) issues with synching.

    Either do Windows Control Panel → Administrative Tools and then picking "Services" or typing "Services.msc" in the Run command on Start menu.

  • ITunes 10.5.3, Unable to Load Class Data from Sync Services, Crashes Repeatedly

    Ever since iTunes 10.5.3 on my Windows 7 x64 box, I've been having serious problems keeping iTunes running:
    1)  Any time I connect my iPhone or iPad, or any time they attempt to sync over WiFi, I get the 'Unable to load class data from sync services' error.  It's worth mention that the iPhone or iPad do actually then proceed to sync correctly, and all media / data is synchronized successfully, as far as I've been able to tell.  I've reset sync history, restored the iPhone and iPad, manually moved the SyncServices directory, set both the iPhone and iPad up as new, completely uninstalled iTunes and the mobile device software, re-installed, and *nothing* I do fixes this issue or even seems to impact it.  Uninstalling iTunes 10.5.3 and reinstalling iTunes 10.5.2 resolves this error.
    2)  iTunes 10.5.3 has serious crashing problems on my machine, though I've searched through forums and found a lot of other people with the problem.  In my case, sporadically as iTunes access the iTunes store (for example, I can always make it happen by subscribing to the Diggnation podcast and telling it to refresh the podcast), I get a full application crash which generates the following event in the event log:
    Faulting application name: iTunes.exe, version: 10.5.3.3, time stamp: 0x4f14cc3d
    Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e211319
    Exception code: 0x80000003
    Fault offset: 0x0001280c
    Faulting process id: 0x564
    Faulting application start time: 0x01cce78789dc009a
    Faulting application path: D:\Program Files (x86)\iTunes\iTunes.exe
    Faulting module path: C:\Windows\syswow64\KERNELBASE.dll
    Report Id: ecc77400-537a-11e1-b809-00248c196007
    Again, uninstalling iTunes 10.5.3 and re-installing iTunes 10.5.2 fixes this issue as well, but I really shouldn't have to do that.  Is there any actual solution to these problems other than dowgrading to an older version?
    Yes, I'm running current malware protection (and my system is clean) and yes, I've already checked any other obvious culprits to make sure I don't just have a corrupt library or file somewhere that's causing it.  My Windows 7 install is completely up to date from a Windows Update perspective and also from a driver perspective (even including the motherboard and chipset drivers).  I made sure to do a system file integrity check (sfc /scannow) and it confirmed my install of Windows isn't suspect, but beyond all that I was able to reproduce these failures on a completely separate machine running Windows 7 x64, without any of my media library or data on it -- iTunes 10.5.3 just seems to be bad news on Windows 7 x64 for me, even though I know there are definitely people are using it successfully.  I don't get any other application crashes for any other applications, and I've never had an issue like this with any previous version of iTunes...
    Last but not least, in case it matters, I'm running iOS 5.0.1 on both the iPhone4 and the iPad2.  The iPhone4 is the GSM AT&T model and the iPad2 is the CDMA Verizon model.

    OK, I've given up.  Uninstalled iTunes 10.5.3 permanently.  It's a shame, 10.5.2 works perfectly but 10.5.3 is a complete and total cluster for me.
    Anyone with the same problems who hasn't done this already, just uninstall iTunes and the Apple Mobile Device Service in your Add/Remove Programs, then re-install iTunes 10.5.2.  You won't lose your library or any settings or apps, it will just go back to working again.
    I wish Apple would acknowledge this so that I'd at least know it would be fixed in the future.

  • "Unable to load dataclass information from Sync Services"  Any ideas?

    I upgraded to iTunes 7.7 last night and now I get an annoying constant stream of errors that read "AppleMobileDeviceHelper has stopped working". Multiple reinstalls have not stopped it.
    Against my better judgement, I upgraded my phone to 2.0. Found out that I lost everything on my phone. It is activated and will work but I cannot sync it with iTunes. All I get is a message stating, "iTunes was unable to load dataclass information from Sync Services. Reconnect or try again later."
    iTunes won't recognize my phone. I can move songs and stuff to it by drop and drag but if I click the "iPhone" in iTunes, nothing happens. I put my phone in recovery mode. iTunes linked to it and reinstalled 2.0 but I still get the same problem.
    I'm real frustrated and Apple has not posted anything about this problem.
    Does anyone have any ideas on what is the going on? Is my phone nerfed?

    Try disabling your firewall, virus SW, and if it still won't sync, I would try disabling the communications services one by one until it clears. When I'm troubleshooting this sort of problem, I first look into the system reports (MY Computer, (right-click) manage, event viewer, Windows Logs, and look into each of the sub log sections for the error. This will often point you in the right direction. If this fails, I do a clean boot with all extraneous run-times and services disabled. usually the problem will be solved. I then start turning on the various run-time routines and services until I find the culprit.
    My attitude about this is that I won't waste my time chasing problems like this unless they are critical. Paying $$$ for a 3G iPhone and then having to troubleshoot the SW is not my cup of tea. I only pursued this because my wife and both kids got 3G's but I have them running both XP and Vista. One Vista machine synced OK, but mine would not. Intellectual curiosity led to find out why.

  • Itunes was unable to load provider data from sync services. Reconnect or try later

    Hi everyone
    This issue has got me stumped.
    I have a Dell Vostro desktop computer with Windows 7 SP1 64 bit edition.
    I used to be able to sync now I cannot bakup or sync.
    The device is an iphone 4s with the latest software IOS 5.1.
    Itunes is version 10.6.0.40, the latest.
    To try to fix this problem I removed itunes/quick time completely. Removed Bonjour, Apple Application Support, Apple Mobile Device Support, Apple Software Update,
    Deleted the itunes and quick time folders, the common file folders and files, deleted anything related to able under appdata local and roaming, removed apple folder under program data, scanned through registry and removed all apple entries.
    Then I rebooted the computer, re-installed itunes/quicktime and have the same error appear again.
    I have gone through this process at least 5 times , but still keep getting the same error, cannot go past it.
    I found a solution on this forum but it only applies to MACOS, could not find anything suitable for windows 7 environment.
    Also searche the web high and low and tried several different advice from people.
    This has to be a bug with Itunes! I would like to hear from Apple developers and programmers why I have to suffer so much to sync my device.
    As a last resort I am planning to rebuild windows 7 from scratch but is is a big job.
    Tried also to disable firewall, antivirus, check the apple windows services are running, nothing works to get me past this error.
    Please help someone!
    Thanks and regards

    "I then followed a tip found in PCWorld  and performed the following:
    1. Make sure iTunes isn't running.
    2. Click Start, type regedit, then press Enter.
    3. Navigate to this Registry location: HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers
    4. Look in the main pane for a key that refers to iTunes. If you find one, delete it, then exit the Registry.
    5. Start iTunes. The offending message should be gone!"
    This actually worked for me! I have struggeled with this error for years, and now it's gone. Thanks!

  • ITunes was unable to load provider data from Sync Services. Reconnect or try again later

    i just had this message for the fist time when trying to sync my iphone 4: "iTunes was unable to load provider data from Sync Services. Reconnect or try again later"
    what i did is that:
    - i unplugged my iphone 4
    - clicked on "edit" in itunes, "Preferences", "devices", "reset synck history"
    - Uninstalled itunes
    - restarted the lap top
    - reinstalled itunes
    then i tired and the iphone synced fine. i tried it a few times and it was fine.
    but i have 2 questions:
    1- could this be cause by excessive syncing, since i do sync my phone almost twice a week.
    2- is what i did good enough for a solution or do i need to rename folders and resort to the other solutions provided?

    OK
    Here's what I did:
    1. Copy all of the contents in C:\Program Files\Common Files\Apple\Apple Application Support to C:\Program Files\Common Files\Apple\Mobile Device Support folder, overwriting anything it if asked.
    2. Rright-click on the Computer icon on your desktop (or in the start menu) and select Properties. Click on Advanced System Settings. Then clik on Environment Variables. If you don't have a user variable called PATH, click New... and add it, or select it and click Edit...
    Now, add to the beginning of the user PATH the following two directories:
    c:\program files\commmon files\apple\Apple Application Support
    c:\program files\commmon files\apple\Mobile Device Support
    Be sure to put a semi-colon (;) between the two directories.
    Click OK three times to save your settings.
    Step #2 might require a reboot.
    After these 2 steps sync works again (touch wood).
    Seems that sometimes there's an additional possibility (which I didn't perform):
    If you are still having problems after following these steps, it's possible another application uses one of the same DLLs as iTunes (but a different version) and Windows is finding it in the PATH before the Apple file paths added above. You can check this by opening a DOS command prompt window and executing the following commands:
    where libxml2.dll
    where sqlite3.dll
    where libtidy.dll
    Examine the pathnames listed by these commands. If any paths are listed before the ...\Common Files\Apple\... paths, you'll want to remove those paths from the PATH environment variable.

  • Unable to load LabVIEW RT from drive

    Trying to boot RT on PXI-8187 controller with original setup, what ever RT boot selection is used either hardware switch or BIOS RT boot option, the terminal will show the following:
    Unable to load LabVIEW RT from drive!
    Booting safe mode from ROM...

    Of course after that you can't do any thing to configure the RT target from the MAX on the host computer.
    Please Help.

    Hi,
    I used the recovery CD to change the file system to NTFS, it took a while and it installed windows XP from scratch differently from FirstWare that ghosts it (I think). And it didn't install any NI stuff what so ever.
    At the end I got the same result as with using the remote system format disk option.
    i.e. The RT controller boots in safe mode displaying the previous message without the mount error but this time I can configure the IP address.
    Still I can't install software to it, I get the list of features to install, I select them and press next, then I get a dialog saying:
    Cannot process install because other dependencies are required:
    LabVIEW RT 1.0.1
    LabVIEW RT 6.0.1
    LabVIEW RT 6.1.0
    LabVIEW RT 7.0.0
    LabVIEW RT 7.1
    Is this a host or RT Controller issue now?
    What's next? Thanks for the help
