ATTO ExpressPCI + SCA (80 pin) SCSI HDD question.

Post by tubanick »

Greetings all.

Running Umax Supermac (w/Sonnet G3 500 mhz upgrade) OS 9.1, 312 Megs RAM, MOTU 2408/324PCI + Audiodesk (I will be upgrading ((har har!)) to DP 3.11 if I can find it used) ATTO expressPCI and stock E100 (FWB) SCSI/network card, Sonnet ATA66 w/Maxtor 20 Gig boot drive.

Am on budget, and want to make best use of gear. Wanted to use spare older Seagate 9.1 Gig SCSI drives in RAID array as "scratch" disk, but am having trouble with them. They are known working drives.

Purchased an ATTO ExpressPCI UL2D card hoping to connect spare 9.1 Gig Seagate SCA (80 pin) SCSI drives to it, and stripe for RAID array with SoftRaid 2.2.2

Even with just one Seagate drive connected to ATTO, it doesn't show up when buss is scanned with Apple, ATTO, or SoftRaid utility. With same drive connected to stock E100 card, it shows up. In fact have already done audio recording with that particular setup.

Any users who know if SCA 80 pin drives, and/or the 80 to 68 pin adapters used to connect them, are incompatible with an ATTO ExpressPCI UL2D card?

TIA for any help. I've spent far too many hours already trying to make this work. (have emailed ATTO but no response....)Yes, yes I know "boo hoo" for me ;^) but as I said trying to make the best use of older, but usuable for my needs, gear.

Are you sure you got the right termination? Auto term, does kaka.
Did you check in ATTO tools, have you zapped the PRAM?
shooting in the dark here. I use the MIles ,and have no problems, accept I ca'nt put the comp to sleep.

Hey Tonio thanks for reply.

Haved tried many things.

-zapped PRAM -swapped PCI slots -disabled some or almost all extensions -tried term on/off -changed ID's etc. etc.

It seems, fwiw to others viewing, that ATTO doesn't like 80 pin (SCA) to 68 pin adaptors. I have to use these on the Seagate 80 pin drives.

For a short bit a couple IBM 68 pin drives were striped and kinda working on ATTO, although one drive has gone hinky. (spinning up then down at random expecially during startup) Regardless I think card likely ok. A single Seagate drive will work on single channel older SCSI card but not on ATTO with adaptor, hence my un-ed-u-makated guess.

Will keep trying, but may have to invest in a couple of used Quantam Atlas IV drives I found. Are 68 pin Ultra160 and should work...... ;)
