Mike Richter, were you born with "Scam Artist" emblazoned on your face? -------------------------------------- http://groups.google.com/groups?selm...mindspring.com ( No Pipsqueaks have been able to prove ANY of the above is a LIBEL ) ( -- despite Mikey claimed to have proof of misquotes !! ) James Perrett squealed: You're using the least reliable method of writing to CD and also writing to the least reliable kind of media. It isn't surprising that you have problems. If you want your archives to last then burn in disc at once mode to decent write once media (and I wouldn't call Memorex decent media). Imagine then Take Two, supposedly a backup software, MUST use the least reliable method of writing to CD -- and that's for Take Two to work IDEALLY!! ======================= From: Mike Richter (Acraptec ****) Subject: A note on Take Two Date: 9/1/99 For Take Two to work IDEALLY, your drive must support packet writing and you must have DCD installed...to do it. ======================= Moreover, the least reliable method of writing to CD was good enough for BACKUP -- even when combined with not-decent CD-RW media: ===================== From: Mike Richter (Acraptec ****) Subject: A note on Take Two Date: 9/1/99 You may back up ...to a DCD-formatted erasable. ===================== |

The OP got bitten by DirectCD bug. And the bug bites decent write once media, too. ====================== From: Mike Richter (Roxio ****) Subject: Direct CD - I know, I know, but could somebody help? Date: 10/7/02 I formatted a new CDR, and successfully burned a 200 MB mpeg file to it. I even ejected it, put it back in, played the file, and everything seemed ok.) But then when I tried to burn the second large file, it appeared to write only about 20 seconds of the mpeg, and then just stopped. packet writing is made for drag-and-drop of smaller files ====================== -------------------------------------- Mike Richter, were you born with "Scam Artist" emblazoned on your face? -------------------------------------- (Mike Richter, any Material Connection w/ Roxio?) |

Combining the flaky UDF fixed-length packets with the tendency of erasables (particularly HS) to forget is LETHAL for archiving. ===================== ------------------- What a Friggin SOB! ------------------- -------------------------------------- Mike Richter, were you born with "Scam Artist" emblazoned on your face? -------------------------------------- (Mike Richter, any Material Connection w/ Roxio?) |

I cannot access two of them. The two I cannot access had a 400MB single PGP encrypted archive on each of them. The two I could access had multiple PGP encrypted archives on them consisting of files no larger than 200MB. I kept getting the message that the drive could not read the format. These were all burned on the same machine last week using the same software on the same day. The discs are Memorex 24X. My drive is a 50X jobber, if all this matters. Is there some reason the two larger files can't be read but the two discs with the smaller files can be read? I just had the disc installed last week and thought it the end of my backup problems. Ha! I had crash problem and now find myself utterly screwed by trusting those damn discs. Any answers? Possibly. I got a pack of 5 of the media you are using. Three consistently fail to verify when I 'fill up' the cd. Changing write speed doesn't help. Try a 10x cd-rw, I have no problem at all with these (Memorex) or old 4x cd-rw of which I have many left over from earlier machine. No problem at all with any cd-r I have used. Dave Cohen I will definitely go lower in speed when I buy the next batch. I'll tell you one thing, I'm going to make sure the next ones are OK by writing them back to my disk before taking it for granted I have them saved. Thanks for answering. Most mastering software offer a veriy option, burn4free does and my LiteOn came with record now which offers same (once you find out where they hide it). Dave Cohen I've scoured the Help section and can find no such animal, except for when formatting the drive. I'm surprised to hear the Memorex is not considered a decent product. Which discs are considered prime? When I want to be sure that my CD is written ok, I do this: Put CD in another drive (not the writer in which it was burned), then wse this little tool: http://www.elpros.si/CDCheck/ to compare the CD against the original files which still are on my disk. Am not sure if this is better than doing the verification in the writer itself, but somehow I feel this is a more robust test. Since I cannot for the life of me find any "verify" function for writing to the disk in my Nero Express, I would try the tool you suggest. However, don't you need a 2nd CD reader on your machine to "compare the CD against the original files?" This is very disheartning to find that after as long a time as these drives have been on the market that they are so undependable. There simply isn't any reason for this situation to be. And they want us to now buy DVD drives? They don't even have a common standard for those things yet. I am looking into how to run 3 hard drives with my machine. In my short experience with CD-RW, I have kind of had it with the whole idea. It has cost me dearly, namely, a few years of collected data files. That button is on the burn page lower section |
