This might sound like an odd suggestion, but have you tried to format a disk in real-mode DOS (i.e. prior to Win98 boot-up into GUI)? I wonder if you have a controller/interface/driver issue within Windows. Your motherboard's BIOS will likely treat the LS-120 drive as drive A: (or B: if you have an …

I just tried using the LS-120 drive to write a single ~1MB file to a floppy disk I previously formatted in a regular FDD. The file is written successfully and can be read using the FDD as well the LS-120 drive. I then tried writing the same file using the FDD and reading it on the LS-120 drive. This …

I am completely inexperienced with LS-120 drives. Are there any special BIOS settings I have to make? Please point out completely obvious stuff as well since again I'm a n00b with those drives. Also I just noticed the IDE activity light is solid on when the drive crashes the PC. If I use the reset …

I think potentially the floppy drive 1.44mb uses a different set of heads on the LS-120, perhaps those are out of alignment or broken/dirty? In my experience, only the LKM-F934 and later are particularly good (and they fail in their own ways), but the previous versions are slow and quite prone to …

My LS-120 acts up like that if the power connector doesn't have a good fitting. Moving the power cable a little sometimes resolves the issue. I don't have any 120MB disks, so my experience is with 1.44MB disks exclusively. Thank you for your suggestion! :-) I just tried moving the cable it but it …

Hey everyone! :-) Yesterday I picked up a bunch of hardware containing among other things a 1998 LS-120 drive made by MATSUSHITA, model LKM-F734-1. It reads and writes 120MB SuperDisks just fine but when trying to read from or write to regular 1.44MB floppies it causes the system to hang under …

An example of a card keyed for but not capable of 1.5V operation is supposed to be the Hercules Kyro II line of cards Lolno. Kyro II was released in P4 era and it works just fine with P4 mobos on Intel chipsets (which are not capable to work with 3.3v). Is this something you have tried yourself …

Easy repair. New inductor, new capacitor, and it should be good to go. Easy repair for someone with the tools and know-how! Really, that's just basic soldering. I'm a total amateur with electronics and I'm confident I could replace those parts. Of course you'll need basic soldering skills and a …

Glad to read you figured it out and got it mostly working! 😃 And really, there's no reason to apologise about that.😉 Btw. could it be the screen is actually working but PCB damage is preventing a signal from being passed through?

Welcome to the forum, Sofu1982!😀 Your motherboard has two memory banks consisting of four slots each. To add memory you have to add four simms of identical size in a bank. No mixing and matching. This is due to the memory bus being 32bits wide and each 30pin simm having an 8bit interface. With many …

That's actually great advice! Thanks a lot! I will first try your suggestion of heating the TMUs individually. If I don't see any difference, I'll then try heating up the RAM ICs in groups of four and see if I can at least pinpoint where the faulty module is :) I don't think it's worth trying it on …

Hey dude, you could try heating up the TMUs and FBI individually with a hair dryer while shielding the other two chips with cardboard or something before starting the PC and running a 3D application to try and find out which chip(s) need to be warm to work correctly? If it's not one of the main …
