Hi guys,

One year ago...i burned an UDF disc. I actually don't know what's the difference between UDF and ISO, but oke, i did it because i wanted to burn big files and an ISO disc won't accept that. But now i'm trying to read it (it's an backup DVD) and it goes wrong. In my first drive it says it's damaged or written in a style not readable for windows. In my second drive he reads the disc, but when i double click on it to open it, everything is empty.

Does someone know what i did wrong and how I can read this disc again.
Thanks in advance,

Moody

Firstly, try using CDRoller or UDF-Reader to see if your data is retrivable.

If you can't then I guess the disc simply contains bad data. It means either the format you set for the CD-writing software wrongly, or an accident extra bit that may be written into the disc causing all the data in it to corrupt. This can occur when the cd burner drive is shakened while burning, or you have excessive loads of software running on the computer that takes up memory such that it affects the data transfer from your computer harddisk to the buffer then to the writable disc. This however seldom happen in todays drives as they are mostly shockproof now. I had afew times experienced such afew years ago when CDR drives were still new.

Regarding about the format in ISO/UDF, I've found some articles that might be useful for your reference..

If you still cannot retrieve your data, just simply format the disc and rewrite the data again. Unfortunately for you if you only have this copy of data.

yeah i had that problem about a year ago, now after a reformat the file seems to be unlocked, no problems sinse, thats for the help on the topic guys!
