I recently posted about my hard drive woes, especially the magic vanishing partition which (holds? held?) about 60 pages of the English translation of a new Calamus manual. The partition still exists, and its statistics (size, etc.) are correct. However, GEMDOS/BIOS will not read it, because its type has been mutated to EEM instead of GEM! How can I change the partition sector without wiping the whole partition? If I can get it back to GEM, I might be able to recover some files before I redo the partition. All help appreciated. Thanks.

Thank you to all those who helped me save my hard drive partition. What I had to do was edit sector 0 of the physical drive and change the partition type from EEM back to GEM. There was minor FAT damage, but I retrieved all of my important files onto floppy. To edit physical sector 0, I had a friend and registered developer use her/his (sorry, Atari, no hints as to the person's identity) CHKDISK3 program to change the partition type. I am still having problems. The Megafile 30 is SCSI device 1 (LUN 0), and the FAST 85 meg ICD drive is SCSI device 0. I am having EXTREME problems writing to or reading from the megafile 30 (more than about 10 bytes, and there is corruption). It works fine hooked directly to the computer, but poorly chained through the ICD drive. Do I need to use shorted DMA cables?
