I am looking at something like 9 gig, but they are tending to be 80 pin, what can I attach to my 7600?

Any 50 pin, one-third height, 3.5" hard disk drive should work in a 7600.

Is there space enough for a 80 -> 50 pin converter?
That should work too.

I'm certain that there is but that does cost $$$ and maybe some ¢¢¢ also

I'd say to look on eBay and "just about anywhere you can"

If your 7600 doesn't have a zip drive, it can support 2 hard drives.

I have 2 hard drives already,

I am having a little trouble finding large(9 gig) 50 pin scsi hard drives, & my 7600 has got;

The scsi chain which at this moment contains, 8x cd drive, 4.23 gig hard drive, 500 meg hard drive.

Then just next to where this scsi chain joins the motherboard is another assumed scsi plug. Then on the other side, next to where pci cards sit is another assumed scsi plug.

I don't mind 50, 68, 80 pin whatever but didn't know if you could connect 68 pin & or 80 pin easily.

Lets keep looking.

Is this a good buy?

80 pin drives should work just fine, I used one in my 9600.

Adaptors are not that expensive. Should be around 10 UKP

You should be aware that 80pin (SCA) drives cannot self terminate, the adaptor cannot terminate it either.

IIRC all Apple branded CCD drives can auto terminate so make sure one of them is on the end of the chain, which it probably is anyway. This will save you a lot of headaches.

Have you considered an IDE PCI card? Retail for around 30-50 UKP you can then buy an ultra cheap IDE HD, Barracuda IVs are around 50 UKP for 40 gig and are extremely quiet.

Most drives over 9 gig are designed for servers this is why it's hard to find them and when you do they have 80 pin connectors. It's also why they are cheap on eBay as most people don't seem to think of using an adaptor.

Just whatever you do don't buy a reatial SCSI drive in the UK, the prices are outrageous.

They make large SCSI drives... it's just that there are fewer consumer oriented computers (like macs) that now use them... however SUN workstations (almost server grade ) use SCSI too....

back on topic though...

I think that only one of those 'suspected' ports actually IS a scsi port, the other has something to do with being an AV 'thinger' DAV iThink...

the one next to the scsi port will work, however you'd have a hard time routing the scsi cable UP to the drive arewa iThink.

dav, Ive heard of that.

The one next to my used scsi yes thats what I thought how to fit cabling. Cheers for the replies

The second SCSI connector found in 7500, 7600, 8500, and 8600 is connected to the same SCSI bus as the external SCSI connector. This second SCSI bus is not as fast as the internal, fast SCSI, bus used by the CD-ROM and factory-installed internal drives. Also, you will use up one of the SCSI IDs for external devices.

What I don't know is if connecting an HD to the second, internal, slow SCSI connection might not be a really clever idea for situations that need to access two disks simultaneously (e.g., RAID and AV work). I would not be surprised if one would get higher overall throughput by having one actively used disk on one SCSI bus and the other actively used disk on the other SCSI bus. That way data can flow to/from two SCSI devices at the same time. Because the second SCSI bus is not fast scsi, the total performance would only be 1.5 X the performance of having both disks on the same fast SCSI bus.

Using both busses might provide some performance enhancements for RAID and AV applications.

Enjoy your 7600!

On that connector on the other side of the PCI slots - yes, that is a dav connector. As to what's plugged into it, I have no idea as I've never had the occasion to use it. iThink that whatever is plugged into it will be expensive.

That SCSI converter looks like a good buy. There should be enough room in there. I've got a 68 to 50 pin converter on the 4 gig in my 7600 that just barely fits.

Good luck!Go to Top of Page
