I have 2 ST's one has a megafile30 the other has an ICD 30M drive (seagate with SCSI ). I would like to do a one time transfer of LOTS of programs/data between the two. The manual for the megafile30 says I have to open the case to change its drive #'s and that would void the warranty. The ICD did not come with a manual. The ICD has both a DMA out and SCSI out ports (daisy chain). I'm thinking that I should plug the ICD in to the ST's DMA as drives C-D-E ; open the megafile and change the dip switches (but to what I don't know) to make it F-G-H and plug it into the DMA port on the ICD. So waddya think? Anyone know?

Anyone know? I've done it successfully on various Atari drives. (I can't remember about the Megafile 30, but I think that one also.) If you want to try, open the case and change one DIP switch. On some drives the switch to move is the right of three; on others it is the middle one. Look on the circuit board (NOT the switch itself) for some little identifying numbers. If the three switches are labelled 2 1 X, then you want to change the middle one. If they're labelled 4 2 1 then it's the right one. Maybe there are other possibilities, in which case you just have to guess. This will change it from device 0 to device 1. Now daisy chain your two drives to your computer (either order is okay). Turn one on and let it spin up. Then turn the second on and let it spin up. Finally, boot up your computer. If all goes well, all partitions on both drives will be available. The way it works is that the partitions from device 0 are assigned in sequence to C, D, ..., then the ones from device 1, etc. Thus, if you have 3 partitions on each drive, they will come up as C, D, E, F, G, H. Make sure you don't have a ramdisk installed under one of these drive letters. If you don't have TOS 1.4, then be careful of the 40-folder bug when copying masses of files from one disk to the other. You might want to increase the number of folders available using FOLDRxxx.PRG or to reboot periodically. Usual disclaimer: I hope you find this information helpful, but I take no responsibility for its accuracy nor for any damage you may do to your equipment, your data, or for voiding your warranty, so be careful and back up your disks before starting. ================================================== | Michael Fischer | | Arpanet: <fischer-michael@cs.yale.edu> | | Bitnet: <fischer-michael@yalecs.bitnet> | | UUCP: <fischer-michael@yale.UUCP> | ==================================================

Anyone know? I do this all the time using a BMS200 and an SH204 1. yes change the megafile to device address 1. -- in spite of the words, this cannot void your warantee, or they wouldn't have put the switches inside. 2. with the ICD first, you are hoping that their DMA OUT will work properly. -- BMS200 does, some others dont. 3. re megafile: you may not know which end of the three switches is bit 0: as in bits: 2 1 0 if you change bit 0 to a 1, you get address 1. if you change bit 2 to a 1, you get address 4. as long as the ICD DMA out works, you will get both drives if you address it as 1. If 4, you wont (the driver stops after finding no controller). Guess about bit 1, try it. If it fails, set it back, and try the other end. 4. good luck Howard C.
