[QUOTE="pigoo3, post: 1840049, member: 56379"] Thanks Dave for all the additional details...and thankfully a couple of the details I think could be important. Firstly...that SCSI2SD adapter sounds pretty cool...I didn't know they existed. But then again...how many users are trying to adapt a Macintosh SCSI port to SD in 2020?? Ha ha.:) Do you have a link to it?...I'd like to check it out. I also have not heard of someone swapping in a 1.4 megabyte floppy drive & doing the motherboard IC install to make it work. Usually users back then just got an external 1.4Mb floppy. As far as the link. I guess I thought you were working with OS 7.5.3 image files (I think this was mentioned in post #1)...in post #5 you said they aren't disk images. Ok so here's the possible important part. Sounds like you have an external floppy drive connected to the iMac G5...and then a 2nd (different) floppy drive inside the Mac SE. What I've learned after years & years of messing around with old computer equipment is (regarding floppy drives)...as long as all the floppy drives you're working with are relatively new (not too many "miles" on them)...taking a floppy disk from one drive & using it in a 2nd drive to move files around works fine. But...when one or both of the floppy drives are older...issues & errors start to show up. Seems that the read/write mechanisms in the floppy drives as they wear out kind of change alignment. If you format & use a floppy disk in one floppy drive...all is ok. But when you format & use a floppy disk in one older floppy drive...then take that disk to a 2nd older floppy drive...the 2nd floppy drive may not read the floppy at all (due to the formatting & writing the floppy from floppy drive #1). If the floppy disk formatted & written to on floppy drive #1 is inserted & mounted properly on floppy drive #2...then sometimes you might get read/write errors with floppy drive #2. This may or may not be the source of the error's you're getting...but if there was some way to get the files from the iMac G5 to the Mac SE without using a floppy disk or floppy drives at all...then we could eliminate the possibility of the error type -199 as coming from the floppy drives or floppy disks. Once this is done...if issues continue...we can try to tackle them one by one.:) - Nick p.s. Of course there's also the possibility that the uncommon/rare 1.4MB internal floppy drive install into a Mac SE (that only had 800k internal drives)...could possibily be the source of the -199 error. Thus getting the files to the Mac SE without using floppies or floppy drives could bypass any possible error's the 1.4Mb floppy drive may be causing. [/QUOTE]
