tlemons Posted July 4, 2005 Report Share Posted July 4, 2005 Hi Frequently, my Retrospect 7 backups will cause the following message to appear in the System Evnet Viewer log: Event Type: Warning Event Source: Cdrom Event Category: None Event ID: 51 Date: 7/4/2005 Time: 10:17:23 AM User: N/A Computer: JD Description: An error was detected on device \Device\CdRom1 during a paging operation.

I don't see these errors generated frmo any other applicatio. I read through many posts to this forum, trying to find an answer. One poster noted that Retrospect does not provide its own device drivers for DVD drives, but uses what is present in the system. I looked at the driver stack for my DVD drive, and found drivers from four applications. I de-installed all applications, and was left with just Microsoft provided drivers. But the problem above continued. I've also read in this forum that Retrospect does things that other applicatinos don't. These are done, so I've read in the interest of making sure Retrospect 'does it right'. But, as I look at these errors occur, time after time, with non idea what they mean, on a device that other applications use without error, I'm not seeing the goodness. I've Google'd and searched the Microsoft web site, with no help on what might cause this error. Any thoughts? Thanks tl Link to comment Share on other sites More sharing options...
tlemons Posted July 4, 2005 Author Report Share Posted July 4, 2005 According to the Microsoft web site: Details Product: Windows Operating System ID: 51 Source: Cdrom Version: 5.2 Symbolic Name: IO_WARNING_PAGING_FAILURE Message: An error was detected on device %1 during a paging operation. Explanation An input/output (I/O) request to a memory-mapped file failed and the operation was retried. User Action No user action is required. Okay, so why would an I/O request to a memory-mapped file fail? Is this memory-mapped file a Retrospect file, or is it a file that Retrospect is trying to back up? I'm on my third try to back up some files on disk. Retrospect seems to back up some smaller file, including my Outlook .pst/ost files, but it seems to be stuck on backing up a large .mpg file. Thanks in advance for your advice. tl Link to comment Share on other sites More sharing options...
michaeln Posted August 11, 2005 Report Share Posted August 11, 2005 Hi, Here's a couple questions: 1. What kind of CD/DVD writer do you have? Please go to Configure > Devices > Environment and list the line regarding your drive information. 2. Can you try a backup to a file backup set on a hard drive and see if a similar error occurs? Also, please make sure you are running 7.0.326 and RDU 7.0.6.108. Thanks. Link to comment Share on other sites More sharing options...
jelenko Posted August 11, 2005 Report Share Posted August 11, 2005 Yep, I get the same errors all the time. I think it's because Windows doesn't recognize the file format Retro uses to write to CD/DVD's. Link to comment Share on other sites More sharing options...
