This post describes how to fix the following error message on an Akai S3000XL:
"waiting for hard disk ready.. SKIP" (pictured below)
What's Causing The Error Message
The most common reason for this error message is that the SCSI fuse is blown. ["SCSI is a set of standards for physically connecting and transferring data between computers and peripheral devices." source: wikipedia]. Essentially, SCSI is the protocol that Akai used which allows you to connect to external hard disks. Instead of storing and retrieving your samples on floppy disks, you can store them on external hard drives.
This is the original soldered fuse you need to replace (it's already been removed when the picture was taken). You can replace it with an identical one, but it makes more sense to replace it with an easily replaceable glass fuse so that you don't have to re-solder a new one every time a fuse blows.
The original fuse location is shown here
The Tools And Parts
The tools and parts needed for the project are shown below.
Philips Screw Driver
Ratchet with 5mm Socket (extension may be needed for easier access)
Needle Nose Pliers
1A Glass Fuse
Glass Fuse Holder
If the Glass Fuse Holder wires are not at least 30cm (1ft) long then you'll also need:
60cm (2ft) of 20 to 24 AWG gauge Electrical Wire
or 30cm (1ft) of 20 to 24 AWG doubled Electrical Wire (2 independently insulated wires fused together with the insulation)
Heat Shrink Tubing (or Electrical Tape)
This is the fuse holder you will be replacing the original Fuse with. Make sure you're replacing it using a 1A glass fuse. The fuse holder I bought came with a 30A fuse, which may result in electronic damage. To be safe, use a 1A glass fuse.
How To Fix It:
First remove the top cover/casing. The picture below shows the top cover already removed. The red arrows point to the screw holes. I removed the screws from the outside.
There's two screws on either side of the unit:
Take note of the circuit board containing outputs 1 through 8 shown below:
This circuit board needs to be removed in order to access the blown fuse. Remove all of the screws that attach this circuit board to the rear panel:
Remove the power socket from the rear panel so you can remove the rear panel:
Remove the 4 screws keeping the rear panel to the side panels:
Once the circuit board is removed, you'll have access to the fuse. Removing the rear panel provides even greater access for soldering. Remove the fuse with the help of the soldering iron, and replace the fuse connections with 30cm (1 foot) of wire for each connection.
(the following two steps are only required if your Glass Fuse Holder wires are less than 30cm/1ft long, like mine was):
Make sure to solder the wire extension to the fuse holder as shown here:
Make sure to use heat shrink tubing (or electrical tape) on any exposed wire like I've done. This will prevent any short circuits:
That completes the repair. Before re-installing the removed circuit board, you need to make sure the installed wire is neatly tucked below said removed circuit board. Tuck it like so:
Now re-install the rear panel then the removed circuit board. Once complete the fuse holder will be freely available as shown:
The rest is easy. Just re-install the remaining panels and screws in the reverse order that they were removed. You now have a repaired Akai S3000XL, and if the newly installed fuse should ever blow, all you have to do is remove 4 screws, take the top panel off, and replace the 1A glass fuse in the fuse holder, and away you go!
A big shout out to Gearslutz member "Don Solaris". His post is what helped me fix this error message on my Akai sampler. Here's a link to the original post:
