Good morning, everyone, My problems with my Iyonix have been discussed on two threads, one in Iyonix Support and the other in Archive on Line. I'll go over the essentials as briefly as possible. On returning from a 3 week holiday and switching the Io on, it crashed downloading mail. It then refused to do many things and reported that the Disc Maps were incompatible. DiscKnight reported the disc as good and the maps OK. Verify also said the disc was good. CheckMap professed to reinstate the maps but it lied. I suspected the known Iyonix PSU problem and that seemed to be the conclusion of most of the contributers to the discussion. I bought a new power supply, installed it but the problem wasn't solved. However the power supply died after a couple of minutes and stayed that way. Given the fact that the PSU failed it was still likely that the old PSU was responsible. Mevertheless, I felt that I could try out the other hypothesis (that is: I have a genuine Map problem) and therefore reformat the disc and transfer all the data back again. I have now done so using the old PSU and it is successful. I had a dreadful time working out how to use Hform, however. For anyone interested here is the output from the successful run: Hform V 2.54 21 21 Jan 2003 Format which drive (4 - 7)? IDE Drive ADFS:: identifies itself as: Description : MAXOR STM3160212A Firmware version : 3.AAJ Configuration : 16383 cylinders, 16 heads & 63 sectors/track This drive supports LBA option Total LBA size : 312581808 Sectors Suggested shape : 84573 cylinders, 16 heads This disc was last formatted using the non-standard disc shape 59500 cylinders, 16 heads & 231 sectors/track Parking cylinder 84572, Initialation flag 1, LBA flag 1 Do you wish to retain this shape?

(Y,N)Y Are you SURE you want to do this to disc ADFS::4 (Y,N)Y Formatting 69499 PRESSING THE SPACE BAR WILL CAUSE THE SOAK TEST TO END AT THE END OF THE NEXT CYCLE. Verifying . . . The wait on the line 'Verifying' was nerve-wrackingly long. There was a cursor winking steadily after the dot on the last line and there was also a line of text output below this when the process finished, but I was too involved to copy it. One interesting thing was that right through this process as far as the start of 'Verifying' I could still see, via ShareFS, that all the data on the Iyonix disc was still there (or appeared to be). When I went back to the Iyonix, the desktop was there with all the applications I had on the icon bar present and the short cuts to various directories, but disc 4 was utterly empty. It took about 5 hours to return all the data. Some of the runs that did not succeed got mired down because the choice of some of the options led to new questions that I didn't know how to answer. Another failed because I kept putting Long or Short or None in the question about the soak test when this should have been L, S or N. Thank you to everyone who took an interest in my problem. I shall be away until early next week but I couldn't wait until then to proclaim the good news!
