[CentOS] URGENT: Problems with Dell raid on CentOS 4?

[Peter Farrow]

Glad it was of some use,

If you are copying Windows partitions with G4U there is a utility to 
zero out the empty parts of the partitions, which allows the Gzip 
compression to be more effective....

Otherwise a 20Gig Partition takes up 20Gigs on the ftp server....
