THANKS, Ted! Looks like I'm getting another Floppy Drive to try out.

startup sequence is like an old PC…. 

Floppy seek first- find floppy with OS then boot. 
No floppy, do HD seek- find OS, boot. 

If your OS is corrupt on the hard drive (equivalent to when a PC says "Missing Operating System"), then you have to reload the OS onto the drive. 
You would need a good floppy with OS to boot from and write it to the HD. 

I have seen this on Emax when the Hard Drive is going bad... 

You shouldn't need a new EPROM. 
If you had a bad EPROM, I would think it wouldn't even do the SCSI seek 1through 7 

Just my .02

I just bought a NEW Sony MPF920-E and switched the ID # by breaking off the 0 Ohm resistor and bridging the SEL 0 jumper (as this one has no switch). By the way this is as technical as I know how to talk! So this did not work for me. 

My old drive usually worked (only every once in a while would it say DISC ERROR or something like that). The reason I bought a new floppy drive (for $10) was because I was told on this list serve that my HD would cycle off at the startup because it needed to use the FLOPPY to read the OS. Or something like that. I never understood the startup order or anything. 

So I am back at not being able to either startup (it checks SCSI 1 2 3 4 5 6 7 and repeats but never finds FLOPPY, I think), nor access my 80MB Apple HD. When seeking help before, I was advised my OS is corrupted and needs new EPROM or something. 

Any suggestions? Sorry I'm not very technically minded!

i had several old emax drives i have been testing them over the last few weeks and can confirm that all have misaligment issues 



i tested each one with disk written from a new slim floppy in one emax machine then loaded it into a test machine with each floppy drive and all failed to load the new disk 



so i did more experiments by formatting the drives in the emu with the old drives and they formated the disk and would load from that drive but when i tried loading the disk into one of the other old drives and the new slim floppy i got errors 



as i promised these drives for free to members i dont think its fair on you to send them as you creating a disk on a pc might not work and would be a waste of postal money on your part and wastage of both our times youy can get them realigned by a floppy repairers but its cheaper to buy a nos slim floppy for £5-10 and a slim floppy adapter and do the mods yourself 



of get a hxc as they work if you have no scsi 



if you have scsi i do recommend a cf scsi card drive either a pcd-47 pcd-50 pcd-60 or a acard 7720uw and a hpt swap drive as it loads fast and 35 banks at hand
