- Open The Box!
-
- Is your hard disk drive future-proof? With pliers between teeth, Colin
- Monro takes the plunge...
-
- In 1993, I bought my first hard drive for my Atari 1040STFM. One of the
- Gasteiner "Mega Drive" series, it was only long after the warranty had
- expired, that curiosity overcame me and I opened the box. Inside was the
- host adapter board with real-time clock (about three times the size of the
- modern ICD Link adapter), a power supply unit, the 47MB disk drive
- (physically huge by today's standards) and...a big space. With a spare
- power lead trailing from the PSU, it was obvious that the yawning gap was
- intended was intended for a second drive. This was not that uncommon in
- those days--Protar Series 1 and ICD FaST drives amongst others left
- similar spaces for extra mechanisms. Times change, and so does equipment.
- The Gasteiner drive was switched to running my 4MB STE and my MIDI kit.
- Even after tidying up the partitions, though, it became apparent that I
- wasn't going to get too many 16-bit audio samples on it, and so I took the
- plunge to fill that space.
-
- It's almost impossible these days to buy a hard disk under 1GB new, but
- after cruising the "for sale" topics of the CiX bulletin board, I bought a
- six month-old bare Maxtor drive--£50 for a 290MB model. Despite having
- been in a Mac, all it required was re-partitioning. Both the ICD utilities
- and HD-Driver software can do this for you.
-
- And now, the disclaimer. If I'm an idiot, and erase all my valuable song
- files and samples by fiddling with hard disks, that's my fault. You
- undertake this kind of operation at your own risk, so always, always, back
- up your data from the original drive. Next, not all SCSI drives are
- created equally. They have different jumper settings, power requirements,
- physical sizes, and most annoyingly, the mounting holes never seem to be
- in the same place from one to the other! None of this is insurmountable,
- it just requires some patience...
-
- Tooling Up
-
- So you've acquired a second drive mechanism, you've got appropriate tools:
- flat and star bladed screwdrivers, pliers, a hand drill preferably--you
- can use a power tool but be sure to remove all the components from your
- drive casing first because electronic components will not like the
- vibrations. A hand drill worked slowly and surely is much more gentle (it
- took me fifteen minutes to drill each hole). Choose a flat worktop, with
- plenty of containers for screws, brackets and cables.
-
- Softly Softly
-
- Having disconnected your hard drive, unscrew it and open the box (the
- design varies between manufacturers). Note the orientation of any power
- plugs, leads, and mounting brackets. Draw diagrams if necessary, this
- will help when you try to put it all back together and discover you have
- spare bits left over!
-
- Unless you've opted for the power drill approach, all you need remove is
- the original hard disk. Treat this with care, put it in an anti-static bag
- preferably, and stow it away from your work area and over-zealous elbows.
-
- Treat your new hard disk drive with the same respect: you should only need
- to handle it to mark out where the mounting screws should be placed on the
- floor of the case. These mounting screws should preferably have spacers
- fitted over them to give the drive clearance of air under it--but
- correct-sized nuts will do. Some disk drive cases have vents on their
- floors as well as a selection of pre-drilled holes.
-
-
- Bits For More Bytes
-
- You'll require two principal components: firstly, a power lead to connect
- your new drive to the internal power supply unit. If one is not already
- attached to the PSU, you can buy a "two into one" cable. Second, you need
- a special SCSI ribbon data cable that will allow two (or more) devices to
- be connected. Take your time with these, make dry runs if you like, to
- assess the best way to lay these cables so that they do not snag on the
- case lid or the other bits of equipment.
-
- You may also require some jumper blocks for your drive or indeed drives.
- Jumpers are little plastic-coated pegs that fit onto a series of pins on
- the back of the disk drive to set the SCSI ID number. If your original
- case allowed push-button setting of ID numbers, this must be disabled as
- the new mechanism must have a unique number.
-
- Shameless Plugging
-
- Things are looking good; you've attached that new hard disk, re-attached
- the old one, and you've plugged those all-important cables into them. Be
- careful with those connections--while the plugs and sockets on SCSI ribbon
- and power cables are usually designed to fit one way only, make sure they
- are seated firmly in the sockets. This applies particularly to the SCSI
- ribbon connector. Press firmly and evenly on it-- seating it squint may
- cause data loss, bent pins and a whole lot of frustration after you've
- spent careful minutes re-assembling the case and booting up.
-
- Once the hard disk box is sealed tightly, it's time to connect it to your
- Atari, boot your machine and run your preferred hard disk utilities from
- floppy disk. Install or modify your hard disk driver, partition your new
- device to your liking and then start installing that software you didn't
- have room for before. Not forgetting of course, to give yourself a pat on
- the back!

- ** Boxout 1 **
- Jumper Settings for ID numbers
-
- The "first" pin on a jumper setting block will have Pin A or similar
- marked on it. After that, the pins follow a binary number system. Thus,
- pin A is 1of, Pin B is 2 of, and so on. Using these with a jumper
- allows you to set any ID between 0 and 7.
