Compression Multi Volume Woes

[Darthvader]

I just created a multi volume rar file out of an image and burnt it on 5 discs. Well Winrar made the 4 files 700 mb and the last one abt 434 mb
for 3.4 gb file.

Now the problem is my 1st disc has got corrupted
Now i still have the image file on HDD
Wat i am asking is can i replicated the first volume only so that i do not need to waste another 4 discs.

Then can the remaining volumes continue from that newly created first volume.

If yes how??

Umm, I think not, cause the CRC ID changes... wait for some other solutions please cause I think there is a way to avoid that but I donot know it exactly...
