Desktop fails on compare using supported Hardware


Recommended Posts

I am having problems backing up to a CD/RW - where the backup appears to work fine, but will fail on verification with a -100 error.

 

The device (CD/RW - LG CED-8120B) is listed on your website as being supported but I find that it only works for very small backups.

 

I have exhausted the website support as well as my patience, Please help!

 

 

 

Scenario-

 

Backup < 100 MB to a CD/R and verify - no problem.

 

Backup > 300 MB to a CD/R problem arises during the verification phase. Actually the verification occurs at about the same point in the verification. Always about 1/2 way through the first disk the verification will fail. This is regardless of a 500MB backup or an 8GB backup.

 

 

 

CD/RW - LG CED-8120B (using secondary IDE channel as master, logical drive W:)

 

 

 

Installed in IBM Intellistation E - pro (6836-41U)

 

On secondary IDE interface with original CD-R as IDE slave, logical drive R:.

 

 

 

OS: Winnt 4.0/SP6

 

 

 

RAM 1,128MB

 

P3 @ 1GHz

 

 

 

All data collected after turning NT passthru on as recommended by your website.

 

 

 

Example 1, with Older Verbatim CD/R media - deep blue tint.
