Overlapping partitions

[David Baron <d_baron@012.net.il>]

Long time problem. My partitions used to be legal-steven but somehow got 
messed up. Main problem is that there is cylinder overlap (which defeats 
parted, partitionmagic, etc). The ordering problem is fixable but not really 
the problem (There was a primary Windows partition that was 
eliminated--recent poster, take care).

   Device Boot      Start         End      Blocks   Id  System
/dev/hdc1   *       65520       77600     6088635   83  Linux
/dev/hdc2               1       65519    33021544+   f  W95 Ext'd (LBA)

/dev/hdc5               1       38753    19531449    b  W95 FAT32
/dev/hdc6           38753       46504     3906250+  83  Linux
/dev/hdc7           46504       52704     3125000+  83  Linux
/dev/hdc8           52704       56579     1953125+  83  Linux
/dev/hdc9           56580       60455     1953125+  83  Linux
/dev/hdc10          60455       65519     2552603   83  Linux

The fdisk "verify" complains that partitions 5 and 6 overlap. How would I (and 
how safe would it be to) change the /dev/hdc6 end to 46503 (and possibly the 
hdc9 end to 60454) ?? 

I need to move stuff around to make room in hdc1 so I need to canonize this 
disk somehow :-) There have been no data errors.
