|
|
<P>I found a Frame and 1 drawer removable drive mount for $20.00.
|
|
It is the "SNT MOBILE RACK". Disks didn't cost me anything because I
|
|
had several old or small IDE drives around from upgrades etc. Even if
|
|
you have to buy them, 2GB IDE drives are cheap.
|
|
<P>

|
|
</H2>
|
|
|
|
<P>1. Once you decide whether your removable drive is going to be a
|
|
master or slave, make sure and jumper it properly before securing it
|
|
in its case. If you forget this step it can take quit a while to trace
|
|
booting problems back to an improper jumper setting.
|
|
<P>
|
|
<P>2. Make sure that O/S installation routines can ONLY see the drive
|
|
they are installing to. RedHat refused to let me install LILO to the
|
|
SCSI MBR if it could see the IDE drive. So, to install to an internal
|
|
SCSI drive, I had to physically remove the IDE. To install to the IDE,
|
|
I had to disable SCSI support in the BIOS.
|
|
<P>
|
|
<P>3. If an O/S installation routine tells you it is going to repartition
|
|
ALL your drives and overwrite EVERYTHING believe it.
|
|
<P>
|
|
<P>4. It is very easy to install an IDE cable backwards.
|
|
<P>
|
|
<P>5. I only tested an IDE master/master set up. I am not sure how a
|
|
master/slave would work.
|
|
<P>
|
|
<P>6. Installing the removable disk frame does require opening up the
|
|
computer case. If you are uncomfortable with this get a friend to help.
|
|
<P>
|
|
<P>7. If you set the removable disk to a specific disk type in the BIOS
|
|
it will work fine until you replace it with another disk of a different
|
|
type. Then you will get errors or warnings and the system might not boot.
|
|
<P>
|
|
<P>8. Plan everything in advance.
|
|
<P>
|
|
<P>9. With a quick change to the BIOS, the second disk becomes your
|
|
boot disk. This means that you can have a fully functional O/S available
|
|
as your emergency/recovery disk.
|
|
