Mr. Platinum CD-RW 700 MB

[Zigge]

My brother bought a few Mr. Platinum CD-RW 700 MB (####://www.itbutikken.dk/default.asp?sprog=46&varenr=gi07 ... it's a Danish shop) but he has trouble with them.

He has tried to write 696 MB to it with:
Easy Cd Creator 3.5
Easy Cd Creator 5
Nero

And he has used:
Windows 98
Windows 2000

And he has tried a 5 MB file as well.

He can't format the CD's ... when he tries to write to it, it says writeprotected.

He has got a HP 9110i-writer. Has anyone tried these?
