Disconnecting & Reconnecting the 2nd HDD from the Notebooks Operating System .....
|Posted originally by WiKDMoNKY
I went into the device manager and changed the policy to disable "Write
Caching" and it didnt give me an option to Safely remove hardware.
I know when the DVD rom is in the bay it shows the Safely Remove Hardware
applet in the system tray.
But not with the second hard drive in the bay.
Has anyone been able to make this work?

Disabling write caching isn't what allows you to use the "safely remove
hardware" option. You have to make Windows recognize the drive as removable
to get that. (and if you do that, you don't have to disable write caching)
I don't know how to define an internal hard drive as removable, but someone
Hello peoples,There is a definitive solution to the dilemma that Dual Hard Drive users, like those quoted above, have.
The term that covers the situations above is Hot Swapping
and in the case of IDE Hard Drives the solution is software based.
The solution is called Swap Manager
by ViPower or Mobilexperts and in its present version (v4) it allows you to control up to 24 devices, including not only IDE hard drives but also USB (and I think also Firewire & Serial ATA)
It will not allow you to swap the boot drive (primary IDE channel - Master on HDD "0") on an IDE notebook, but on some PC type motherboards that allow you to boot the 2nd, 3rd or 4th hard drive this may be possible.
However safely disconnecting or reconnecting
a second IDE hard drive from the primary or secondary channel data bus is easily done using Swap Manager
I know of a chap whose used it very successfully with Switched Removable IDE Drive caddy's for over 5 years. So when experts (can someone know verything?) say "you can't hot swap IDE hard drives" just walk away before the start of an argument, safe in the knowledge that you can hot swap in a similar method to the Safe Removal method that Windows XP allows with USB, Firewire A(400) & B(800) and Serial ATA. The only proviso I know of is that version 4 doesn't like many - if any at all, Internet Explorer windows to be open when you're switching devices on or off. You might well say well "why would you want to have IE windows open ...." well I can't say but I often change drives while keeping the PC running and prefer to keep IE running if possible. However I think he's tried "hot swapping" with FireFox browser open and it all works happily.You can obtain Swap Manager by using either of the following links:http://www.vipower.com.tw/FreeTrialSoftware.htm
The current cost is USD $19.95 to unlock it from the trial (limited) downloaded version.
==================================================2 Hard Drives means using a lot of Battery Power?
With your current setups your second hard drive is running all the time and consuming extra battery power when your not using the mains adaptor.
Unless you switch off the second hard drives caddy the hard drive will still be electrically powered up but no longer connected to the bus/transferring data.
It should be relatively simple to install a small single or double pole switch into the face plate of the caddy to allow you to switch the harddrive drive on or off, just in the same way that some removable hard drive caddy's control power (and data transfer) to the hard drive. The hard drive connector has four pins separate to the data pins that control the power and whilst I've not worked out how to buy a second caddy yet (any assistance will be gratefully accepted
) it should be easy enough to trace the correct paths on the small P
oard, then cut the path and solder the wires to the switch. A 3.5 inch IDE hard drive caddy may use a switch or depending on the manufacturer
they may even be switched via a small transistorised arrangment, which would not be difficult to design and build. Pictures on this forum indicate there's enough space inside the caddy for a switch & or a few electronic components and is probably about 30 minutes work for a techie (or a teenager!).
Here is a link to a good source of pinout information on just about every computer device know to mankind: http://www.technick.net/public/code/pinouts.php
This following page at the same site as listed above is specifically for the 2.5 inch IDE Hard Drive. http://www.technick.net/public/code/...nhdd_ata44_int
The pins in question would - I suggest, be 41 & 42.
==================================================How are you going to write your CD's & DVD's now that your writer is no longer [internally] connected?
May I suggest the following device which I've found on eBay. (I am in no way associated with or to the seller

This slim external CD or DVD writer case
appears to be identical to the USB 2.0 slim external case that was supplied to me with a Panasonic burner, right down to the same cardboard box. Your Dell CD or DVD writer should just plug straight into the P
oard that you can see in the picture and is held in place by the its plug/socket and 2 screws (from memory). There is also a USB B type socket on the rear of the black case which connects with the cable supplied straight into one of your notebooks USB sockets. Too easy! + no need for mains voltage adaptors
