![]() ![]() I bought the drive adapter and connected to it. The incompatibilities generally come from the software side, but Greaseweazle doesn't mind for example 360rpm vs 300rpm spin rate, and when dumping disks you should still get a good analysis in software such as HxC track analyser ( ) Other things to try are a more modern 5.25 drive. ![]() Possibly you need input pullups of 1k to +5v on pins 8 (INDEX), 26 (TRK0), 28 (WRPROT), 30 (RDATA).The MCU cannot drive directly into 150 ohm, you would need to add buffering, or remove that termination pack (possibly replacing it with 1kohm pullups). Input termination on your drive is 150 ohm instead of 1kohm.Drive select is not on pin 12 (DS1) on your drive, but on pin 10 (DS0).Some other possible problems (in descending order of likelihood): Easy to makea mistake in the mess of wires. The above is most likely problem (simple bad connection) if you are directly connecting. The following pins must be correctly connected for Track 0 initialisation to work properly: Pins 12 (SELECT), 18 (DIR), 20 (STEP), 26 (TRK0). If 5.25 2D 360KB IBM-PC format works good with greaseweazle, So many Korean people will be very grateful to you.Īre you directly connecting a Blue Pill to your drive with Dupont wires (not using an adapter board)? Then check your connections carefully. So I have question for you, weather 360KB 2D IBM-PC format is not your intetest yet or I did something wrong. (But 2HD 5.25 1.2MB IBM-PC formatted diskettes do work well with 5.25 1.2MB 2HD floppy drive.) Reading Track 0.0.Command Failed: Seek: Track 0 not found"ģ60KB 2DD formatted diskettes don't work with both 5.25 2HD and 2D drives. It means reading and writing does not operate well. So that? 2DD 5.25 360KB ibm-pc formatted diskette does not working using greaseweazle. ![]() I know 5.25 shugart pin-out is different from that of 5.25 IBM. Your core theme of the project is Shugart, but IBM-PC format doesn't seem to be out of your interest. (I'm vice manager of online-community for "DOS/win3.1") So many Korean people whose hobbies are collecting retro IBM-PC are glad to meet your project! ![]()
