I've decided to buy a 20 meg hard disk and I was wondering what some of the experiences have been with both the Atari and Supra varieties (or other HD's for that matter). I was reading that the Supra's don't have a fan, but that the Atari's do. Does it make any difference? Any opinions on them are welcome. Thanks Bart atwell@utah-cs

[] Add-on hard disks (for IBMs, say) are cheap since they come with no box and no power supply. Those can easily add $75 or more. Could people who have attached SCSI drives tell us about this added problem? (Radio Shack sells a surplus unit, originally designed for the Adam, that gives 5V/1A, -5V/100mA, 12V/300mA. I don't think that's enough for any hard disks (?) but it's great for many other things, e.g. that SECOND megabyte. And they only ask $5 for it! Go get a pair :-) - Moshe Braner

If this is true, how hard is it to select and connect a power supply for the new hard drive, especially if you have little experience with that sort of thing? Bart atwell@utah-cs

I'm considering buying a hard disk for my 1040. I've got some questions about which I should get. I don't plan to use my atari forever, and I'd like to be able to use the hard disk on the next machine I buy. Will SCSI (or whatever the acronym is) be around in the future? Is it worth my time to buy a hard disk and plan to use it on another machine? I almost think that the hard disk I buy today will be piddlingly small compared to disks of the same price in ten years. What are the brands and prices of the hard disks on the market? what drivers are needed for each hard disk? Special utilities (format, backup, etc)? I think it would be a GREAT service to all prospective hard disk buyers if those of you with hard disks could send me a description of your set up, I'll compile the results into a message and post it. --Rodney

If Atari ever sends me the replacement for my ST (hey, folks, I'm still
waiting), and if I make it through the holidays without going into bankruptcy,
I'd like to hack together a low-budget hard drive. What I'm thinking of is:
* Atari's host adaptor, which at least one dealer will sell me for $60.
* Adaptec 4000, which I think Computer Surplus will sell for around $80.
* An ST-506-type 10MB hard disk, which I see advertised for around $90.
* ICD's formatting software, which is free.
* A case from a junk electronics shop.
* Cables, which I may be able to scrounge.
* A power supply (cost unknown).
The whole package should be up and running (if it runs at all) for under $300.
Now, to the point of this note: Is there any reason why I should NOT put
together such a system? Warnings about pitfalls and hidden gremlins would be
welcomed. (To my pnet51 address, please, since thelake, my ST, is still off
the air.)

Yes, I think that you should go ahead and build your own drive if you've got the time. However, I personally wouldn't bother buying a 10 MB drive. How much more would a 20 MB cost you? If the answer is $50-$70 I would go ahead and buy the extra capacity up front. You'll probably want it before long. Good Luck! Ron Abramson P.S. Last time I checked, my opinions were my own, but I could be mistaken.

There was a good article in STart by Dave Small a few years back about how to attach two hard disk mechs to a currently functioning hard drive. It works something like this : One drive has to be logical unit 0, one drive has to be logical unit 1. Set the jumpers/switches/whatever on the disk mechs in this manner. Both drives are connected by a (non-twisted) 34 pin ribbon cable. The cable runs from one drive mech to the next drive mech to the seagate->scsi interface. The drive that is in the middle has its terminating resistor removed. The one on the end doesn't : it is the terminating drive. Each drive is connected by a 20 pin cable to the interface. Logically selected drive 0 is connected to the interface's connection #0, drive #1 goes to interface connection #1. Both drives need power, and that's just about everything you need to know. Some 34 pin cables have a 5-pin segment twisted around between two of the connectors.. this is for swapping drive select signals -- in this case I believe that both disk mechs should be set to logical unit 0. (I use a non-twisted cable..) I followed the article by Small in STart when I hooked up my system and have had few troubles. The system I use is a BMS ACSI-->SCSI interface, an adaptec 4070 SCSI-->ST506(RLL) interface, a Seagate 238R and a Seagate 277R. This totals approximately 95 MB at a cost of around $1000. The BMS board doesn't seem to have attracted much attention on this Newsgroup discussion.. I recommend it, especially if you're in the Berkeley area. When my hard disk died (my own fault), I took my system to their shack and they kindly helped me out with data recovery. No fancy sign off - Dan Filner c184-au@holden.berkeley.edu

I have a 1040ST and an IBM clone. Is it possible for me to set up a system so that they could share an external hard disk? Can I get a system with a switch that could route the signals to a 1040 or the IBM? This SEEMS kinda easy but hey I studied software not hardware so what do I know? ;-) If I could do this then it would justify blowing big bucks on a great harddisk/tape backup system. Thanks Ron

A month ago I purchased a 1040STe and have upgraded it to 4 Megs. I now want to buy a hard disk in the $500-$600 range preferably >= 50 Megs and not slow with clock and ICD Adv+. Anybody got anything to say about these choices: D & P Computer's 85 MB 28 MS $584 Joppa Computer Products 82 MB 19MS $609 Toad Computers 85MB 24MS $599 L & Y Electronics Supra 110 MB $599 Rising Star Computers ICE Systems 85MB $579 If you know of anybody else in this price/performance range that I should consider - explain ?

A while ago I posted a plea for information concerning hard disk drives. I am in the market for one and I'm interested in what is being used out there. Whats good, bad? Why? For example, is the Supra any good? Is it slow/fast/noisy? Forget about that Amiga crap - I need some honest help here! Bob Malay

Frankly, I recommend everyone to buy ICD stuff, be it internal or external.
The problem of hard drives is much of a software nature and I think most
people agree that ICD's are the best. And then you can buy any of the
SCSI drives in the market. Mine is Conner Peripherals' SCSI drive housed
by a Japanese case and power supply, etc. and it is quieter than my MEGA ST.
The speed? It is rather slow but 570 KB per second, which isn't too bad (
I understand 500+ KB per second things are generally regarded as fast).
Cheers,
Tsuji
