Cannot blank CD-RW succesfully.


Yo!

Please help, I cannot use CDRW's at all. Actually I have never been able to use them properly, in Windows 2000. I think they are really unsecure backup, what do you think? I hope I am wrong.

Anyway I cannot blank it, neither I cannot use it. They seem to be locked somehow.

I use commands like this:


cdrecord -v -eject speed=4 dev=0,0,0 blank=all


Here is the result of mine, its brand new CDRW disk:

aight ... cdrws for backup are as useful todays as floppies were 7 years ago it now takes just as many rw's as it took fdds then. and they are just as useless in storing the data. it's a shame kodak gold gold disks aren't available in Oz anymore but such is life.

As for blanking the cdrws, i'd firstly suggest you try it using xcdroast (which is a frontend for cdrecord) although i'm sure you are using the command right i really don't know (i'll research it at some stage )

the other thing is, if you can't blank an rw in windows, with the software that came with the burner, then odds are the burner is stuffed, take it back for warranty, or ask them to show you how it's done (and then when they screw up ask them for a warranty replacement) heck they sold it to you, least they can do is spare a minute and 30 secs (which is how long a blanking takes on average) to make sure it works right.

Incidentally, you're other thread about not being able to write cd's is most likely linked to this, so check it out with a mate, that has a burner also, se what he does, do it on your system and if you know what you're up to hard ware wise, chuck his/her burner into your machine and try from there.

Many thanks for reply. I knew this - CDRW is not really good innovation. Now you tell me the same.

Grafical user interface does not help me to understand anything. I dont understand it - no matter how well I read the manual - I will allways fail. I start to feel a bit like USER,n. ( I am not an it specialist, but I just LOVE its jargon!:-) )


Yes...I have taken THREE TIMES my CD writer back!

This latest cdrecorder is the best. I need to change the brand. Hewlett-Packard is simply shit. But CD-R's work really well. No complaining at all!! It has allways been this way. Any suggestions, please?

But you know what: I need to buy USB FLASH ROM circuit. That should be good idea. But it should have 512 Mt in it, cos I make grafics, but maybe its worth of the money.

Any experiences?

no real experience with flash rom and so forth. If you are having so many issues with the rw's maybe your media is damaged, maybe you left it lying in the sun, or before you got it it got too hot, it's possible, (and not all that unlikely).
Try buying a new CDRW and see how you go. (by all logic it should work at least some times....)

the GUI suggestion wasn't meant to aid understanding btw, the reason i suggested it was that i don't know how to burn from the console (i'll have to look into it some time :P ) but i figured maybe there was a switch missing or maybe a wrong option used. I'm not implying you're dumb or something, but what xcdroast passes to cdrecord works due to alot of testing.

By all means you are smarter than a program, but the dumb program does it right, cause it don't know how to do it wrong.

Well...no matter how good or bad is my CDRW disket, it allways fails in the end. You do not need to use it for too long time, until some file comes so corrupted that you cannot use that file.

I avoid to show sunlight for my cd's, and no matter how what I do it fails. I mean really brand new record do not work.

I have given up with cdrw's. As far as I am concerned the USB flash rom circuit is the only really functional solution. In the future this device will replace modern harddisks. Its really strong, you can drop it or throw it to wall and nothing happens. Its really small. First military tanks and jetplanes will get this harddisk replacement. Its so strong.

It will also help to make computer really small.
