Are all 7,500/10,000 HDs IDE?
« on: April 02, 2003, 04:20:00 PM »
Can anyone advise how I can add a HUGE hard drive to my PM9500?

I'm a 'Bear of very little brain' and cannot keep (mental) track of all the abbreviations attached to the available products on ebay's Mac and PC auction sites.

My 9500 has 2 spare PCI slots.

Do I need a special PCI card to add an IDE drive to my 9500?
If so, I cannot find one on ebay under any 'Macintosh' option whilst they are available on the PC sites.

Is this because PCI/IDE cards are specific to PCs?
Or, is it that PC users don't know that PCI cards are cross-platform?

Are PCI cards cross-platform?

Oh boy!! Do I need help??????

Any advice (pleeeease)!!

Regards to everyone

While not being overly familiar with the 9500, you should be able to add an IDE drive, along with the PCI IDE/ATA controller.

Something like this:

or this:
http://eshop.macsales.com/Catalog_Item.cfm...tem=SIISCMP4A12

And you do need a Mac-compatible PCI card - any old card won't do.

There are big SCSI drives (which is what you have already) available, but they tend to be somewhat expensive. Of course, once you add in the cost of having to buy the PCI card, they may not appear all that expensive.

For instance, lowest price for a 73GB Maxtor (10,000RPM) SCSI drive on Pricewatch.com is $173. A Western Digital 80GB 7200RPM IDE drive is about $79. Furthermore, larger SCSI drives are enormously expensive - 146GB drives are around $700!!! You can get IDE/ATA drives for $1/GB or less these days.

There's a bunch of useful info here:

http://xlr8yourmac.com/IDE.html

Further caveat - I've never found eBay a good source of reliable, cheap hard drives. For some unknown reason, people seem to have a very fuzzy notion of a hard drive's retail/on sale price and I regularly see prices bid up OVER regular or sale prices. Also, eBay is littered with people selling dodgy drives - some are upfront about it (and with drives with 3 year warranties, some people bid these up too, figuring they can get them replaced by the manufacturer under warranty), but I don't recommend it for the best source of a quality drive. Also, be aware that the drive manufacturers have recently all shortened their drive warranties to ONE year, with a few exceptions. One of the exceptions is the Western Digital Special Edition drive (80GB, 120GB and maybe a larger model...) - which carries a 3 year warranty. It's fast (has an 8MB cache) and quiet. I have a 120GB model and am very happy with it. The best source of info on specials is http://www.dealmac.com . You can also look for bargains at http://www.pricewatch.com .

When it comes to ATA/IDE drives, they all work with Macs, as long as you have an ATA PCI controller. They may come with software for PC's, but Drive Setup or Disk Utility does a good job of initializing and partitioning. One of the dangers of buying a used HD, is that if it has been formatted with a third party utility of some sort, the Mac may not recognize it unless you also have that utility. I've never had a problem with a Mac refusing to recognize a drive formatted for a PC (it wants to initialize it of course), but I've heard horror stories about people trying to get drives recognized when they've been formatted with third party Mac utilities. So, save yourself some headaches, and buy a new one!

Hi David,

Your 9500 has built in SCSI, but not IDE support.  So as Paddy suggested, you will have to get an PCI IDE controller card for newer, faster, cheaper more compatible IDE drives.

You can get a fast SCSI drive, but they are very very expensive and your SCSI controller may not really take full advantage of the faster drive.

The SIIG IDE controller card that Paddy linked to in her post is the same one that I have and when benchmarked with a 7200 rpm drive, the benchmark go through the roof.  I recommend this card fully.  I also believe that ACARD makes this card and has their own version of the exact same hardware.

"Do I need a special PCI card to add an IDE drive to my 9500?"

Yes.

"If so, I cannot find one on ebay under any 'Macintosh' option whilst they are available on the PC sites."

PC IDE cards will not work in your Mac.

"Is this because PCI/IDE cards are specific to PCs?
Or, is it that PC users don't know that PCI cards are cross-platform?"


IDE cards are not specific to PCs; however, in order to work on a Mac, the card must have a special chip containing a Mac driver. Cards without this chip won't work.

You need a PCI IDE card that specifically states it will work with a Mac. Several of these cards are available.

"Are PCI cards cross-platform?"

No. PCI itself is cross-platform, but the *software* on the card is not. The cards contain special software embedded in chips inside the card; the software on the card is specific to Macs or PCs.

What that means is that any PCI card will FIT in your Mac, but it won't WORK in your Mac unless it has a Mac driver on the card.
