Can't get CD drive recognised

[Astral]

I'm setting up a 4g CF drive + CD slim drive in my 1200. No probs getting CF formatted and booting when it's the only thing connected to the IDE cable - and gees it's fast! But, as soon as I connect the CD drive, neither the CF or CD drive is recognised. I've tried connecting each device on different fittings on the cable. The only jumper to change master/slave settings is on the CF card - which I've tried all combinations of - master/slave, slave/master, and no jumper at all. There is no master/slave jumper that I can see on the CD drive, and I think that's where the problem lies - not being able to set them means the master/slave settings are clashing. Has anyone come across this and knows how to sort it out? Can I just cut a particular wire on the cable, or bridge some pins or similar?

I can't reply in relation to my A1200 as I run an external CDROM off my Ferret SCSI, but my A4000 has a little unit called a 4 Way IDE Buffer.  These units in combination with IDEFIX software fix most IDE issues and provide 2 IDE Ports both with master/slave.  There are some problems with some Accelerators you should be aware of however which requite a CTRL-A-A after switch on for the system to boot.  So verify your accelerator isn't one of them before purchase.

There should be a way without resorting to buying another adaptor. A normal sized drive is recognised fine, but that has a master/slave jumper on it - which my slim one doesn't. I have confidence once the settings can be set properly all will be ok - that's what I'm thinking...

I've tried resetting to test for slow drives, accelerator and so on - no difference.

I think this "All newer IDE/EIDE hard drives can be jumpered as Cable Select (CS or CSEL). This is an alternate way to indicate which drive is master and which drive is slave (instead of jumpering one drive as master and one drive as slave). Cable Select jumpering requires a special IDE cable with wire 28 not connected to one of the drive connectors, which would configure the drive attached to that connector as the slave drive." might be part of the solution.

Hi,

After playing with my A1200 for the past 6 months trying to get a CF drive and a CDROM going, I found out that I had to buy a buffered cable at AmigaKit, not only did I have to buy a buffered 4 way ide cable but I had to use IDEfix 97, I had to put the CF on the primary ide side, and the CDROM on the secondary side to get it to work on a regular 68K CPU. Now comes the fun part, when I initiated my PPC CPU, I had to get rid of the CD drive, use a regular ide hard drive as the master, and the CDROM as the slave. Now why did it take me 6 months to figure this out.

1 My first power supply went bad, replaced the power supply got rid of intermittent power problems.
2. Found that when my power supply went bad, it burned a wire in my ide cable, the burned out spot was the size of a pencil point.
3. When I replaced the cable I used a CS select cable, which has a hole punched in at one selected end.

These problems were enough to cause a crazy man to go insane. So now you see why I am so looney.

Anyway take it from me, CF drives are great if used by themselves. My CF drive has a master and slave on it, for what I don't know, because I have tried over 1000 different things to get it to work, and believe me I couldn't get it to work with either a CF drive, a regular ide hard drive, or a CD Rom.

Have fun, and if you figure it out give me a yell. Just letting you know that I played with this project for 6 months, now it is set up with a 4 way ide buffered, with a regular hard drive as master, a CDROM as slave and running a Blizzard PPC with OS 4.1 (Don't waste your money OS 4.1 running on a 250 mhz drive is slower than a 68000 chip, I use OS 4.1 only to say I have it, got to get something back for my $149.)
