- PRODUCT NAME
-
- Western Digital Caviar hard disk
-
-
- BRIEF DESCRIPTION
-
- An 340-megabyte, 3.5-inch, IDE hard disk for the Amiga 1200, Amiga
- 600, or any Amiga with an IDE controller.
-
-
- COMPANY INFORMATION
-
- Sorry, but I purchased the hard drive as part of a package, so I
- don't know any supplier information. If anyone knows the information,
- please send it to amiga-reviews@math.uh.edu.
-
-
- LIST PRICE
-
- Again, I don't know, since I bought it with a computer. I
- think around $600 (US) might be right.
-
-
- SPECIAL HARDWARE AND SOFTWARE REQUIREMENTS
-
- HARDWARE
-
- An IDE hard disk drive controller is required.
-
- Every disk partition requires 30K of RAM. If you have
- a base model Amiga, such as a 1 MB Amiga 600, you may
- want to get a RAM expansion.
-
- CPU speed also plays its part here. Hard disk operations
- (read, write) are faster if you have an accelerated CPU and
- some Fast RAM. I have also installed DiskExpander (which
- itself needs RAM to compress/decompress the data).
-
- SOFTWARE
-
- None required.
-
- If you would like to partition the hard disk, then you need
- some "prepping" software. There are freely distributable
- programs on the Aminet ftp site for doing this.
-
-
- COPY PROTECTION
-
- None.
-
-
- MACHINE USED FOR TESTING
-
- Amiga 1200 series, 2MB Chip RAM, 4MB Fast RAM.
- Internal 880K floppy drive.
- External high density floppy drive.
- Kickstart 39.106 (3.0), Workbench 40.35 (3.1).

- REVIEW
-
- If you own an Amiga without a hard disk, you ain't lived! ;)
- Honestly, though, the difference between a floppy based system and a hard
- disk based system is immense!
-
- Ever since I sold my Amiga 500, I've wanted more power. The A1200
- was the obvious, affordable choice; and coupled with 6 megabytes of RAM and
- a hard disk, I thought it would be a killer product! Well, I took the
- plunge and bought a system, and it has brought me nothing but pleasure. I
- think you don't know what the Amiga can do until you have a fairly fast
- machine (68020 or better), lots of memory, and a large hard disk... or at
- least that's what I've found. :)
-
- Being the curious type, I have tested the hard disk performance just
- to know how it is compared to the other hard disks available. I was
- pleasantly surprised to learn this is a very fast hard disk indeed! Just to
- show that I am not cheating, I have used two programs to test the hard disk,
- and both report similar results. The drive was tested with two different
- benchmark programs -- SysInfo version 3 and SPSTrans version 1.01 -- before
- and after I got my Fast RAM. The results are tabulated below.
-

- SysInfo 1.78 Megabytes per second 1.41 Megabytes per Second
- SPSTrans 1.76 Megabytes per second 1.39 Megabytes per Second

-
- LIKES AND DISLIKES
-
- What do I like about this hard disk? Everything! It does what it
- is supposed to do very well.
-
-
- COMPARISON TO OTHER SIMILAR PRODUCTS
-
- Although I have friends with A1200 computers and hard disks, they
- don't have Fast RAM. Therefore, all the details next are for a basic A1200
- (my Fast RAM removed). I know these figures, as I had to sort the machines
- for my friends because I know how to do it and they don't! >8)

- BUGS
-
-
- None found. The drives mentioned above seem to have problems. One
- of them seems to spin up, but the "Insert Kickstart" 3.0 animation is
- shown. A warm reset cures this; but if it was my machine, I would be very
- annoyed. ;)
-
- One thing to note is that HDToolBox uses some very strange MASK
- number as a default value. Therefore, when you re-partition the drive, you
- must enter the correct one(s). The values at present are:
-
- Mask : 0x7ffffffc
- Max Transfer : 0x1fe00
-
- These values seem to work fine.
-
-
- VENDOR SUPPORT
-
- Never returned it! >8)
-
-
- WARRANTY
-
- One year warranty on the computer provided by CBM itself, and one
- year on the drive by Western Digital.

- CONCLUSIONS
-
- If you've been thinking of getting a large capacity hard disk, then
- this would be a nice choice. Also, if you plan to buy a hard disk again,
- this is a good choice. It may seem like a lot of disk space, but I've
- filled about 80% of it and I'm still going strong.;) (Thats if I was to
- uncompress the data that is already compressed.) If you think it's still too
- much here the result from the AmigaDos INFO command:
-

- The partition "SYS:" is compressed using the xpkNUKE compression library.

-
- For a final result, I give this hard disk five stars out of five.
- It works just like it should, and it is very good compared to other hard
- disks that work on the A1200.
