Attach 3,5" HD to Laptop

Hi AnandTechies!

I've got a Problem. I need to attach a 3,5" device to a 2,5" Laptop HD Connector. My first idea was to do this with a 2,5" to 3,5" adaptor used for attaching laptop HDs to dektop computers, but it didn't work. The laptop didn't recognise the HD doing absolutely nothing, hanging in its startup phase.

The Laptop is a Toshiba T2150CDT

Any help aprechiated!

Thanks for reading 🙂
 
the easiest thing to do is probably going to be an external case. because the laptop drives get power from the connector and desktop drives don't i dunno if you can do it the way you're trying.
 
I've got an external housing for the 3.5HD and power for that is provided, too. So the external HD is spinning up seems functional.

But powering up the Laptop has no effect on the ext. HD. And the Laptop itself hangs in its pre-boot mode (LCD-not activated, no Mem-Check, etc.) With no HD attached (adaptor removed) it boots to "Insert System Disk and press return".

Any ideas? From the stuff I found on the net about 2.5 IDE and 3.5 IDE cableing I thought the PIN-structure is identical inspite of the fact that 2.5 Drives are also powered via the IDE cables 4 extra lines.

Could it be that Laptop recognises that the power it provides for the internal drive is not used and so "thinks" there must be a problem and doesn't boot?
 
I'd suggest just using an external firwire or usb enclosure, or powering the HDD w/ an AT powersupply or something of that nature, I doubt the laptop will provide enough juice to power a standard 3.5" ide drive. and a desktops firware may not be compatible w/ a laptops bios. Hope this helps... 🙂
 
From the way it sounds you are tryin to boot from this drive which i have never seen done before. Why if i may ask are you tryin to boot this way?

The 'juice' 🙂 is not a problem. I've got an external enclosure with seperate powering.

I've got hold of a HW-Mirroring RAID device and thought of building a small low power consuming home server with it and the old 486 Toshiba Laptop I had.
And yes, I'd like to boot from that 😉
 
Sneaky in all my years which i have 2 admit arn't as many is alot of peeps in here. I have never seen nor heard of this being done. Not to say it is impossable as if you state that you are askin for someone to prove u wrong. But as stated before i have never seen it done. I think it would be hard to set up and get workin properly.

If you are talking about an OLD 486, are you sure the bios can handle the size drive you want to use?
