Verification Issue

[36548]

Recently used Express to backed up my system drive to a LG CD/RW 8120B Dantz certified burner.This drive doesn't have the "Burn Technology" but is one of the few drives that has a 8Mb internal buffer which helps that situation. After completion, I looked in operation log and all backup set sessions were successful. No errors of any kind. I continued and made a "Disaster Recovery CD". Restarted PC and booted off it and system came up in DOS as advertised ready to go with the Retrospect package if needed. Then I started to do a "Verify" on CD/R Disks and ran into following problem: Consistently on the second disk the verify program stops and tells me that process was halted because of an ERROR 100 (Device Rejected Command). Now, of course I don't know if my data is good to go or not when disaster strikes. My experience with CD/R burning tells me this technology is not quite there yet for consumer use and most of the time you deal with problems with brands, read errors, write errors, Buffer Underun,etc. It's just not there yet in my opinion and now we're moving on to DVD. Oh Boy! By the way I've learned not to price skimp on the media and have had best luck with Sony CD/R's. However, now I don't know what I got going on. Anyone out there experience this problem and come up with a solution.Thanks!

An error -100 is reported by the hardware itself and can be an indication of many things. I've listed below some things to check for when getting these kinds of errors. This is a relatively common error and I suspect that with a little troubleshooting you'll be able to isolate and fix the problem.

 

 

 

Did you have verification turned on at the time of the backup? If not, there may have been problems during the original copy that were not detected.

 

 

 

Have you tried other brands of discs? Often problems like this are due to drives that are picky with regard to brand of media you use. Sony is a great brand, so you may just have a faulty disc.

 

 

 

Try *temporarily* uninstalling any other CD-writing utilities, in case extraneous drivers are conflicting with Retrospect. If you are using DirectCD, this can cause a conflict; I've included directions below on how to disable some functions of the software that may interfere with Retrospect.

 

 

 

Turn off the Auto Insert notification for Windows. This feature makes the operating system automatically mount a CD on the desktop when you insert it, but can interfere with Retrospect. To disable it, right-click on your CD drive in the device manager.

 

 

 

Was ASPI installed correctly? Run ASPICHK (in the Retrospect Program Files folder) to make sure ASPI is "green" and all components are at version 4.60. If not, try a reinstall (ASPIINST.exe). If you still have problems, consult the Retrospect User's Guide or Adaptec's website.

 

 

 

Is this Windows NT or 2000? If so, enable NT SCSI Passthrough to bypass ASPI: From the Retrospect Directory hit Ctrl-Alt-P-P. Under "Execution," check "Enable NT SCSI Passthrough." Click OK. Quit and relaunch.

 

 

 

If you still don't have any luck, I'd recommend the following hardware troubleshooting steps.

 

 

 

ATAPI:

 

 

 

Try straightening out the internal ribbon cabling.

 

 

 

Try switching master and slave settings.

 

 

 

Try new internal cabling.

 

 

 

Try updating the firmware on the device if possible (see the drive manufacturer's website).

 

 

 

Are the drivers for the IDE controller current? Try updating them with an approved update from your PC vendor.

 

 

 

Finally, try bringing this drive to another PC and trying the backup. If it works here, you could be having a problem with either the ATAPI bus on the original machine or with the PC itself.

 

 

 

It is not possible to go through many of these steps during the actual Disaster Recovery process. My goal was to include some of the relevent possibilities in any situation.

 

 

 

If you continally get an Error -100 on only disc 2, this would indicate the disc is bad, and you will not be able to restore from this piece of media.

Disabling DirectCD:

 

 

 

There are three possible scenarios:

 

 

 

1) You have both components of the program (Direct CD and Easy CD Creator)

 

2) You have only Direct CD

 

3) You have only Easy CD Creator

 

 

 

Do you have one or both components installed? Go to Start -> Programs, and look for Adaptec Easy CD Creator. If it is not installed, look for the second component of this which is in the system tray (bottom right hand corner of the screen). This is the Direct CD Wizard.

 

 

 

If you have Easy CD Creator and it is not in the system tray you can put it there by launching Easy CD Creator from Start -> Programs -> Easy CD Creator. This will then give you an Easy CD Creator Title Screen. You can add it to your task bar by right-clicking on the Title screen. In the next screen, select "Add icon to tray," which should then put an icon into the system tray. It will look like a CD with a musical note. To disable this, right click on the icon and select disable create CD.

 

 

 

The next part of the program is the Direct CD wizard. It is an icon found in the system tray and looks like a CD drive with an ejected CD. To turn off the disk creation options for blank media, right-click on the icon and select properties. In properties, select the Direct CD wizard, then uncheck the Display disc creation options for blank media. This will stop Easy CD creator from launching when a new CD is inserted.

After several hours of patience, and countless coaster making, I have a theory as to why I kept getting the Error 100 message every time I tried to verify backup sets. First of all I tried various suggestions of making sure Retrospect had the CD/RW's undivided attention. That didn't work! I tried different CD/R Media Brands that included Sony, Memorex, and TDK. That didn't work either! As a last resort I tried some Memorex 4x's CD/RW media and again tried a backup followed by a verify. Guess what? This worked! I never got any indication of a problem while making the backups in any of my attempts. Always verifying data was the problem area which would be a problem upon recovery attempt. The drive in question is certified and is a LG 8120B. My theory is this. I think the drive is throttled to high for CD/R use with the Dantz driver. I also think that data files got corrupted during the burn and the error 100 is not necessarily the correct message to send out to the user. Since Dantz takes control of the CD/RW, I'm wondering if this is the case? The CD/RW is max. 4x's on R/W media and this slower rate seems to have solved my problem. As a suggestion to Dantz developers maybe it would be worthwhile on future releases to include the speed handles for users to try if problems arise. Since you take control of the drive, any handles under properties is rendered useless right? Most of the burner software that I have experience with allows you to adjust R/W speeds. At least now everything seems to work like the Desktop Version of Retrospect I use at work to back up network drives onto DLT. What I mean here is that it works with know problems.
