Divide error ?....

I think my hard drive is dying.
I was able to boot into it and run scandisk with no problems but when I tried to run defrag it would not start the program but just locked up.
Do you think my data on the hard drive maybe corrupt ?

Sometimes it boots and sometimes it hangs on boot up and sometimes I get a “HD controller” error.
But I don’t think there is anything wrong with the controller and I already changed out the IDE cable.

The drive is SLOW to spin up too.

I don’t have anything else hooked up to this IDE channel but the hard drive.
And I have the floppy hooked up to the floppy channel.
The floppy drive works fine.

The controller detects the harddrive fine.
But sometimes I get the “HD controller” error on boot up.
I think it is the harddrive that is failing and not the controller.

Has anyone seen this before ?

Hard drive is a “Conner IDE 524mb.”.

Maybe I need to change the jumpers?
Does anyone have the manual for this drive ?

You are an IT guy from that period. I'm sure you should be able to figure out what is wrong without help from us plebs easily enough.

Is it possible to use an internet search engine on your iPad by any chance?

Well, I found this manual but not sure about what settings to use ?
https://stason.org/TULARC/pc/hard-drives-hdd/ … -HH-IDE-AT.html

DSP & SS
--------
This pair of jumpers determines the signals on pin 39 of the inter-
face connector.
+-------------+---------------------------------------------------+
| Jumper |Description |
|DSP |SS | |
+------+------+---------------------------------------------------+
|CLOSED|OPEN |- spindle synchronization signal is disabled on |
| | | pin 39 |
| | |- activity LED signal available on pin 39 |
+------+------+---------------------------------------------------+
|OPEN |CLOSED|- spindle synchronization signal enabled on pin 39 |
| | |- activity LED signal disabled from pin 39 |
+------+------+---------------------------------------------------+
|OPEN |OPEN |- pin 39 floating |
+------+------+---------------------------------------------------+
Master/slave in CAM compatible mode uses pin 39 in a time multiplexed
manner to indicate that a slave drive is present. During power-on-
reset or after RESET is asserted, this line is asserted by the slave
drive within 400 ms to indicate its presence. The master drive allows
up to 450 ms for the slave drive to assert -HOST SLV/ACT. -HOST SLV/
ACT is deasserted by the slave drive following its acceptance of the
first valid command or after 31 seconds, whichever comes first.

E1/E2/E3
--------
E1 Jumper in disables spin-up at power-on. The drive will
automatically spin up when it receives a command which accesses
the drive.

E2 and E3 UNUSED!

J4 DC Power and pin connector assignments
-------------------------------------------
+--------------------
| +-----J4-----+ pin 1 +12 VDC
| | 1 2 3 4 | pin 2 +12 Volts Return
| +------------+ pin 3 + 5 Volts Return
+----------------- pin 4 + 5 VDC

Were you going to say something about a "Divide error?..." Or did you write your thread subject incorrectly?

He's a bot. Exception occurred during subject generation, obviously.
