floppy controller error Palm Springs, California

GUI element here since my ubuntu box runs as a server with no desktop. And problem occurs anyway in about 10% of tries. Hard disk drive failure with windows 7 Forum Got BSOD with the message "Unexpected_store_exception" and now I get Disk Read Error on boot Forum SolvedCan USB zip drive "disk drive" error To do PIO data transfers: init/reset the controller if needed (see below), select the drive if needed (see below), seek to the correct cylinder, issue a sense interrupt command, then issue

donbecker commented Dec 4, 2015 Same issue happened to me, Windows 7 x64 host deploying Windows Server 2012 R2 a a guest. The suggested delays when turning the motor on are: 300 milliseconds (for a 3.5" floppy). 500 milliseconds (for a 5.25" floppy). If using PIO mode instead, set it to 1. Always turn it off, if you send a Configure command.

I flipped my cable around serveral times and much to my dismay it still didn't work. Note: implementing a failure timeout for each loop and the IRQ is pretty much required -- it is the only way to detect many command errors. Any other pointers/suggestions? Typically the first build will fail with this error and then the next build will succeed with nothing changed in between.

If you have problem with another guest OS please add your details here. In order to access it in Pmode, you need to modify your driver to handle Perpendicular Mode. One floppy controller chip can control 2 floppy cables, for a total of 4 drives. Ha!

No interrupt. I have changed the floppy drive about 3 times, I put 2 different cables in. Repeat while RQM = 1 and NDMA = 1 ((Value & 0xa0) == 0xa0). Note2: some people prefer to give the registers values based on their offset from the base address, and then add the FDC's base address (0x3F0 or 0x370).

A very safe amount would be 30ms. The Floppy Subsystem is Ugly Many of the devices that an OS controls in an x86 system have had functional patches added to them over the years. The Actual Drive In the olden days, there used to be 5.25 inch low-density, high-density, and single-sided drives. The only thing that I have found to consisently resolve this is running headless (regardless of OS).

Turn the drive motor bit on. To calculate the value for the HUT setting from a given time, use "HUT_value = milliseconds * data_rate / 8000000". You should still send them even if you have IRQs turned off in the DOR and you are using PIO polling instead. Software ▼ Security and Virus Office Software PC Gaming See More...

However, it seems likely that the smartest thing to do is just to set the value to 0 (which is the maximum in any mode). thanks for your help But what error code could possibly be worse than a bad sector? fujiiface commented Aug 28, 2016 I ran into this problem and set shutdown_timeout to 1h.

The commands "Recalibrate", "Seek", and "Seek Relative" do not have a result phase, and require an additional "Sense Interrupt" command to be sent. the build now works as before! Write that value to the DSR. So, when your OS is initializing: Send a Version command to the controller.

Reload to refresh your session. The last access may have been attempting to load your bootloader. i have an asus p2b-f mobo The floppy drive controller is integral to the motherboard. Usually this is a 0 (1.44MB floppy drive).

If the value is 0x90, the floppy controller is a 82077AA. For this particular command, you do not have to wait for the command to complete before selecting a different drive, and sending another Recalibrate command to it (but the Step Rates

Standard values for these gap lengths can be found in the floppy controller datasheets. Reliability In real hardware, floppy drives are extremely unreliable. It also seems to be possible to modify this register while the FDC is in "reset state". Or you can try to handle all three, by only using registers and commands that are identical in all 3 modes.
