HELP DISK DRIVE PROBLEM

[A2600]

Fisrt day using again the ST, since the day i put it away... Untill now that I get a Color monitor everything load up fine when I have set up on the floor when I take some crap off my desk and situated the machine nice on my desk with the monitor when I boot I get my little green desktop but now the same programs that booted while it was on the floor wont boot now!!!! All I get is "Drive: A is not responding Please check the disk drive, and insert a disk"

 

PLEASE HELP

[A2600]

Now I get:

"Data on the disk in drive A: may be damaged. You must use the right kind of floppy disk; you must connect your hard disk properly"

[A2600]

OHH BOY

 

Now she is not reading of the Disk Drive or turning on the drive light and when she gets to the desktop doesnt even display the trash can just the mouse by itself!!

 

I have a 1040STf just in case you wanted to know!!

 

I think I have a Virus?!?

It sounds like something is wrong with the disk drive.

 

Open it up an make sure the disk drive cable is securing in. It may have come loose during your computer move.

 

Or, it could be your disk drive biting the dust. Connect any PC disk drive that can be configured to Drive 0 should do the trick. Make sure to twist the cable 180 degrees too.

that can be configured to Drive 0

 

How do I know this and how can it be configured??

[A2600]

Fixed!! Everthing back to normal

that can be configured to Drive 0

Older floppies has jumper for drive select 0 or 1. Newer has only selder pads and you must solder a little.

I dont trust google to do the link right so I will repost this direct from the web. It was written by the author below, not me, so i've never had to do it.

I just had a look during the weekend, so for all interested, here are

the changes you need to perform to a Mitsumi D359T6 floppy drive to use

it on an Atari (ST/TT/Falcon). The Mitsumi drive was the only one I

could find nowadays. It seems to be the cheapest and most widespread

floppy drive used nowadays in most OEM, brandless and homebuilt PCs.

 

To change the drive ID, this unit has no jumpers, however, on the

connector PCB you'll find a small area with 3 rows of 4 tiny solderpads.

You have to make 2 solder bridges, like this (viewed with the connector

to the bottom and the front of the drive facing up)

 

o o o o

o o=o o

o o o=o

 

With this, the drive will be detected by the Atari, but you may

experience problems with the Media change: when you swap disks, the

Atari can ignore the swap, and writes to the new disk using FAT

information of the old disk. This usually corrupts all the data on the

disk, and makes it unrecoverable.

 

The enable the media change detect, you can solder together 2 pins of

the write protect/media change switch (top left of the drive, marked WP

and MC). Bridge the MC and middle pins like this:

|_____|

W | | | M

P | |=| C

 

I haven't tested that part yet, but read a post from somebody claiming

that this corrects the media change bug. I still use the fmc.prg in the

AUTO folder as a precaution.

 

If you want to do the HD mod, then you'll find that pin 2 of the mitsumi

connector does not output +5V when a HD disk is inserted, as it should.

A way around this, is to run a wire directly from the HD detect switch

to pin 2 of the connector. The HD switch is the one opposite to the

WP/MC switch, and has a pin marked HD. You should solder one end of the

wire to this pin, and the other to the connector PCB, where the pin 2 is

soldered to the board.

 

I suspect that the HD detect and Media Change settings can probably be

changed from the "4x3 solderpads" area, but I was unable to find a way

to do so. Maybe someone else has some better information.

Mitsumi drives probaly havent changed signifigantly since this was written so you can give it a shot....

 

good luck!

On TEACs, it's a solder pad on the bottom of the drive labeled DS0 and DS1.

 

However, on the newer drives, I can't find them! Probably to save 2 cents. What a bunch of cheapskate drive manufacturers!!!

 

Time to save up on old drives at the computer junkyard!
