TEAC FD-55GFR and Deviceside

Last night I finally had time to assemble my Deviceside USB->5.25" floppy interface. I decided to do it all slick-like and put the drive in the shell of an old Sony USB CDRW. I have two examples of the TEAC FD-55GFR drive laying around, which is the drive recommended on the developer's site. I attached one to the ext drive carrier and powered on. The drive head started seeking back and forth, not the full travel of the disk, maybe 1/4 of it. It made a loud, steady click and flashed the panel light of the bay, as if it was drawing too much power from the little PSU. However, I went ahead and hooked it up and read disks (DOS 1.2mb, AppleDOS and C64 1541) to images. I haven't fully tested the images yet but they didn't error out during the read. The DOS one was mountable in WinImage, the C64 one in CCS64 (don't have an Apple II em handy.) Still bothered by the noise, I attached a Panasonic JU-475-4 drive instead. It was quiet, no blinking light. I imaged the same disks with that drive and that appeared to work fine, too. Does anyone know the FD-55GFR well? It seems to have an auto-sense mech of some kind, and one of the two I have has a spring-eject (the other may have had it too but the spring is missing?) It seems likely that it would click continuously, searching for a disk. Maybe this is normal behavior for this drive and it seems loud because it's open? It does the head-seek continuously whether there is a disk inserted or not, lever-down or not. This seems bad to have happening on top of the exposed disk surface. Or, again, maybe it's normal for this drive? The easy solution is go with the Panasonic and not worry about it. But I'd like to stick to the developer's recommended drive unless I can be sure the Panasonic is 100% compatible too. -j -- silent700.blogspot.com Retrocomputing and collecting in the Chicago area: http://chiclassiccomp.org
