SSD Drive in Amiga detection issue

[mechy]

I've not found that to be the case, new drives are compatible with older OS's; plus you can change the cluster from 512 up 32K during the install/format process. I've hooked up an SATA 1TB hard drive to my Amiga without any problem, as well as the OCZ SSD as stated above.

I've had reports from a good few people that they simply cannot get some SSD's to work, Unfortunately i dont have a list of what does and what does not. I am guessing its a firmware on some SSD's and i doubt the issue can be fixed. Regular HD's dont seem to ever have this problem.

I've been talking with matt and he's been through all the normal stuff of changing scsi cables etc to eliminate most trouble.

Last thing i suggested was to plug in a regular ide hd into the acard setup and verify it on the amiga. that should tell if its a compatibility problem.

Here is what I have learned:
- Acard adapter has the latest bios.
- Acard and Mercury SSD work fine together in my pc via PC SCSI Card.
- Neither Warp Engine SCSI or A3000 SCSI even see the device anymore.
- Tried almost every combination on the Acard to get it recognized except The WE jumpers.

To my logic since:
- Mousehouse got this device working in his 3k
- The Acard and SSD work in a pc

It should therefore work...

Mech suggested I get the patch from aminet for optical drives and HDToolbox.  I will test that.  

Any ideas out there???

Mfgs change firmwares in stuff constantly,so it may be why his ssd works and yours does not. You can barely count on getting 2 devices that are identical even if the part numbers match these days firmware wise-case in point see how many flash versions there were for the Acard.

You say the amiga recognized it before but not now? Smacks of a bad scsi cable.  Do you have term power(not the same as termination) enabled on the Acard? its a long shot but maybe your A3000 has the term power diode backwards-many had this problem from the factory(pin 25 on the external scsi connector should have +5v).Enabling term power on the acard might help. Be sure the acard has termination on also.

The patch for optical disks will most likely do no good, since you dont have the same error(iirc its type7 for removables ?) it was just a shot in the dark.

test a regular ide HD or cf adapter and cf on it to verify the combo works.

Never thought this would have been an issue since mousehouse reviewed it and since the work perfect together in a pc.  If a pc SCSI card can read the disk through the Acard perfectly, I really would have thought it would work perfect in the Amiga...

Doesn't make sense, everytime I got a drive to work in a pc in the past it always would work in an Amiga...  But it doesn't work so go figure...

I'm not sure sending the duo to anyone will bring different results, if someone can give me a reason why there Amiga SCSI or Warp Engine SCSI is different then mine, I'm game...

I have another mercury SSD in my powerbook running MOS and she is fine.  The other drive is a PATA not a SATA though.  Perhaps Amiga based SCSI isn't compatible with Acards conversion of this particular drive???

Its not a scsi issue, its a acard firmware issue more than likely, as stated the acard scsi to ide bridges are not compatible with everything out there and the firmwares came out long before many pata SSD's.
