HELP please dvd+rw issue

i got a dvd+rw cd, so that means i can format the cd again and again. the memory is 4.7gb but i put some files on it to transfer at my friends house and when i come home to erase the files on the 4.7gb dvd+rw disc i am only left with 1.88gb how come??? i thought dvd+rw discs you can format it and be left with 4.7gb again??? is there something i did wrong??

Please help. Thanks in adavced

 

Which program do you use to erase the disk?
This is a DVD-RW after being erased by 'ImgBurn'

 

i used ashampoo, i click to erase disk then it says disc can not be erased

 

Sounds like a disk problem?
Some software (e.g Nero or ImgBurn) offers the options of a 'Quick' or 'Full' erase.
The full erase takes much longer, but can recover a problematic disk.

 

hi

i'd be inclined to download ImgBurn (which is free.)as attar suggests, never failed me on erasing an rw yet.

there's an understatement lol. it seems to take forever

 

but i tryed with 3 different discs from different companies but none of them seem do erase. do you know when you first use the empty disc are you ment to format it first???, or something like that, my mate told me this

edit: i tryed to erase the disc with the programm that come with your computer all you have to do is right click and press format, i have also tryed ashampoo dvd but i cant erase the disc

 

The disks don't have to be formatted before first use.

Download and install 'ImgBurn'.

Insert a known used disk.

Run ImgBurn.
At some point, ImgBurn will indicate that the disk needs erasing.

Click 'Mode' 'Write'
Click 'Tools' 'Drive' 'Erase Disk'

While your there, do a ['Tools' > 'Drive' > 'Check for firmware updates']
