Kippykip Posted September 9, 2016 Share Posted September 9, 2016 I've been stressing myself out for the past hour, I bought a 5.25" floppy drive for about $250 AUD brand new from floppydisks.com. When it's plugged in and all ready, the only signs of life I hear is a faint buzzing sound from the drive. Only 1 drive shows up in the bios, and changing the setting to 5.25 1.2mb and unplugging the other drive does absolutely nothing. No reading light and no spinning. Going into dos and typing A: just prints a "Seek Error" Does the 775i65g even support 5.25" drives? It has the option in the bios but nothings happening.

jaclaz Posted September 9, 2016 Share Posted September 9, 2016 Just the usual list of semi-random ideas: "straight" or "twisted" cable? any jumper on the actual Floppy drive? does the slot lever close properly? jaclaz Link to comment Share on other sites More sharing options...

It has both, here's a picture I've tried both sides with and without the 3.5 floppy drive connected along side it. 2. It only has 1 jumper, it has 3 pins with a 2 pin Jumper in between it. 3. The Slot lever closes fine, also I should note this is a brand new drive (new old stock?). Extremely good condition by the looks. Also I just tried the drive in another old computer energy star computer (Bios says 2008), and the floppy drive option resets itself to "Disabled" as soon as you leave and save the bios. Maybe 5.25" drives can't be read on modern-ish motherboards even though the bios has the option for it.

It is possible, but unlikely (they would have needed to remove part of the BIOS code), it is more likely that there is an issue of some kind between the cable and the jumper settings, can you post exact model of the floppy drive? Maybe we can find some documentation for it. jaclaz Link to comment Share on other sites More sharing options...

jaclaz Posted September 9, 2016 Share Posted September 9, 2016 You don't have a set of jumpers like?:http://embeddedsw.net/EMUFDD_MITSUMI_Jumpers.html http://www.cbmstuff.com/downloads/5.25-jumpers.pdf I was thinking of lack of termination (or termination that should not be there) and/or DS0/DS1 etc. https://offog.org/notes/archiving/minifloppies/ Sometimes you just need to try every possible combination It's a lot of years I don't fiddle with those 5.25" floppy drives, but I remember them being - in the good ol' times - a real PITA ... jaclaz Link to comment Share on other sites More sharing options...

I'll have a bit of a read, thanks! Link to comment Share on other sites More sharing options...
Kippykip Posted September 9, 2016 Author Share Posted September 9, 2016 The only jumper I can find has a "0" on the left and a "1" on the right. I'll try switching them and I'll write back. Here's some pictures of the drive. Here's the model number: Link to comment Share on other sites More sharing options...
Kippykip Posted September 9, 2016 Author Share Posted September 9, 2016 d***, still not working after changing the jumper or on either one of the plugs. Link to comment Share on other sites More sharing options...
jaclaz Posted September 9, 2016 Share Posted September 9, 2016 It seems like a DS0/DS1 jumper, maybe the drive you have is a "recent" one that has some automagical trick inside that sets all the other options/configurations, the number after the V might be the Version. And yes, the "standard" is DS1 (like it is seemingly set now), but the combination of drive cable and motherboard may need it instead as DS0 This is the V2:http://forum.kryoflux.com/viewtopic.php?t=556 http://embeddedsw.net/EMUFDD_MITSUMI_Jumpers.html and this is a V3:https://gist.github.com/anarchivist/3003928 Cannot find anything specific for the V5, I remember the old ones with several jumpers, so it is likely I am barking up the wrong tree :w00t:. jaclaz Link to comment Share on other sites More sharing options...

The drive gets no activity light and the bottom of it doesn't spin. I'm really stumped at this point, this is the only 5.25" I've ever gotten so I don't even know if the drive isn't working but seems to be really good condition. But yeah so far, the only signs of life is this faint buzzing noise coming from it while the computers on Link to comment Share on other sites More sharing options...
Kippykip Posted September 9, 2016 Author Share Posted September 9, 2016 Turns out that tiny buzzing sound is a small motor on the back of it spinning, it has some creamy stuff on the end of it but I don't know if it means anything. Outside feels warm though. Link to comment Share on other sites More sharing options...
jaclaz Posted September 9, 2016 Share Posted September 9, 2016 That could be the head motor? It is possible that in several years of storage some grease has become "stale" blocking some mechanisms, if it was not a just bought (new) drive it would be the case of (carefully) disassembling it (at least the cover) and manually move the spinner and the heads, but not on something you just paid an awful amount of money for and that should be under warranty. Here is a video representing your floppy drive (or a very similar model): you should be able to see how it works. jaclaz Link to comment Share on other sites More sharing options...

But in the video you can faintly see some white creamy stuff in front of the motor, so I guess that means nothing. Maybe it's the cable? Link to comment Share on other sites More sharing options...
jaclaz Posted September 9, 2016 Share Posted September 9, 2016 Yep, it is possible that it is the cable, but that motor is linked to the heads slide assembly (through a worm screw) so if the motor runs, the head slide should also move. If the motor runs and the head slide remain in the same position, it may mean: 1) the head slide is stuck and the motor can't move it (and there is some mechanism, think of a slip clutch, that makes the motor turn anyway "idle" whenever a given excessive force is needed) 2) the head slide is at the end of its intended travel, and *something* (wrong cable, a position sensor/switch. something else, whatever) keeps the motor powered on (and there is some mechanism as above) 3) for *whatever reasons* the motor is disjointed from the worm screw (which doesn't turn) 4) ... jaclaz Link to comment Share on other sites More sharing options...
