Hello Mac fans. I have an upgraded 128 to 512 k Mac and am now
considering getting a hard disk drive. 40 Mbyte would be nice but
it looks like I can afford only 20 Mbyte. What I would like to know
is what is available out there along with comments (i.e. speed,
reliablility, support, etc.). Thanks for your help and suggestions.

If this is true, I'd appreciate answers to ANY the following questions: - Why is this? I though SCSI had a 'format' command. All you need to tell a Sun (using the 'diag' utility) is the adapter board type, the drive geometry (cylinders,heads,sectors/track, interleave) and it formats just fine. - What components does Apple use in their drives? - How can Apple sell a SCSI card for the II without bundling it with a drive? - Is the Apple II formatter more 'generic' than the Mac version? - Does the Apple II SCSI board use the protocol converter conventions? - What will I need to do if I hook up the following?

I recently bought a Mac-Plus w/ Rodime-20 drive and Radius accelerator board (and Full Page Display). Radius tech support warned me that there was something strange about the way Rodime formats their disks which makes them unusable with the accelerator (some timing snafu having to do with interleave; I confess I didn't quite understand the problem) and they suggested that I reformat the disk with Apple's standard SCSI formatter. I did so, and have been running fine for the past month or so. So, there is at least one example of a thrid party disk which does not need a custom formatter.

Another counter-example: Take a standard off-the-shelf Seagate ST225N disk drive. Wire up an appropriatte SCSI connector to connect to Apples weird DB-25 connector. Apples Standard formatter can then be used to initialize this drive. Only one possible problem: If you want to connect to the non-platinum Mac-pluses, you will have to disable the UNIT ATTENTION feature of the ST225N. This is easily done by sending a "magic" SCSI command to the drive.

I am interested in some information about Hard Drives for a Macintosh Plus computer system. What I am looking for is a drive in the 40 to 60 Megabyte range. I have heard that the MacStack drives from CMS are quite good and there are some attractive prices out there. Any suggestions? Speed is not as much of a major concern as reliability is. I would really appreciate any suggestions whatsoever. Thanks in advance Ben Greenwald CPO 1118 Wheaton College Wheaton, IL 60187

What I am looking for is >a drive in the 40 to 60 Megabyte range. I've had an AppleCrate 60 meg drive for about two months now and have been quite satisfied. I paid $839 for it (direct from the vendor) and it arrived 3 days later, preformatted for the MacPlus. The diskette with the formatting/test utility was unreadable, but I didn't need it to get the hard disk up and running, and they sent a replacement out to me via 2nd day air. I notice no speed difference between it (it's a Seagate internally) and my DataFrame-20 (not XP), except in getting to my larger :-) desktop. I do notice the additional noise, but its not what I would call loud; however the total of the two drives plus SystemSaver fan and peripherals has crossed the threshold of quiet... I now close the door to my home office for total quiet. -- Jeffrey D.

With all this discussion of poor quality control on the
Seagate 60 Meg 40 ms I WAS going to get, can someone tell
me how the Miniscribe 45Meg 28ms is? The former is $589 external,
and the latter $499(int) and $569(ext) from HDI.
Would it be better to go with the 40M Quantum 12ms! at $599
from Optima Series or MacLand, or would the Rodime 45M int 28ms
for $559. (Quantum prices are for internal)
Basically, I would appreciate any info. If you would like,
you can mail to me and I will summarize unless told not to.
Thanks!

Someone who was asking for recommendations on HD's, but I couldn't get mail to: I just bought a Quantum 40 from Optimal. Two of my friends have had them for 10 months and 5 months. Think about Micro Tech - same drive, 5 year warranty instead of just 2. Optimal has a much better mounting bracket than the same drive from Hardware House. The drive is QUICK! Actually it is a 19ms mechanism with hardware caching yeilding 12ms. It has 50,000 hours MTTF. It has head parking on power off, 60G non-operational rating. I am happy (proud owner for 5 days now) and so are my two friends. I don't know if the extra 5 meg would be more important than the speed (refering to Rodime 45 now). The i internal arrangement seems to work well - I left the expansion plate punch out open on my SE case to increase air flow, but I have a Whooping Accerlator card too.

Just a random comment to interject into this massive discussion involving hard drives. My Rodime Hard Drive is awesome!! I have ~28ms access time and 140MB for under $1100 Also, the software that comes with it is very good for partitioning and verifying the hard drive. I haven't seen a better deal yet!

On a macintosh, without exception, in these modern times, seek time is the most important metric relating to perceived disk performance. Buy the fastest drive you can for your money. scott comer

In light of the trouble with Apple drives, the service trouble on the Direct Drives, etc; what would be the company to go with if you are looking to buy a large external drive (100-140 meg range)? I'm looking at buy some drives in this range for use as file server volumes, and some for personal use. So in either case they have to be fast. I don't really card for the software partitioning on the fly, just true partitioning at format time. If I get enough replies I'll post the results.

I would go for Microtech Nova 40, because it uses the faster Quantum drive with the Claimed Access time (ms) of 19, and, 5 years warranty.
