I am about to reformat the HD that came with my Iyonix, and I would be most grateful to anyone who would be so kind as to lay out for me the steps I should follow. I ask because I have a feeling that I saw somewhere that there are some quite catastrophic pitfalls along the path and, even though I have done this exercise before, I cannot remember what the potential problems are, and am consequently paralysed by fear! For what it's worth -- and nobody needs to read the rest of this message! -- the reason for doing this is that I had partitioned the drive a year or so ago to make way for a Linux installation which I eventually gave up on. I now want to repartition the drive so that the entire drive is one partition, which will of course effectively delete the current contents. I have a second HD in the Iyonix, a 250Gb drive which I had hoped to be able to use for Linux, but subsequently discovered that the hardware did not have the top bit set, so could not access any HD address above 128Gb. I have copied the contents of the original drive onto the 250Gb drive, and intend to copy it back onto the original HD once I have done the partitioning. The 250Gb drive will then be removed, to go into a wintel PC which recently had a HD crash. Any help most gratefully received! Anton
