2nd SATA Hard Drive not shown on my computer [Solved/Closed]

shawn - Latest answer on Oct 9, 2012 01:12PM
I have had a WD 160GB SATA hard drive as my primary HD and I recently bought a Seagate 80GB SATA hard drive to use as a secondary storage space. I connected all the power, SATA cables correctly and when I boot my comp, it shows on the display that my WD 160GB is the primary and Seagate 80GB is the slave. However, when I go on to my comptuer, I don't see the new hard drive. When I check the device manager, it still indicates that it recognizes both of my hard drives. Why is it not showing up on my computer to be used?

You need to format the drive before you can use it for data.

Right-Click on the My Computer icon either on your desktop or in the Start Menu and select Manage.

A new window titled Computer Management comes up.
Select Storage from the left hand side by clicking it once, then select Disk Management(local) from the right side by double-clicking it. Find your new drive and format it with one large partition.

First you partition - do a primary partition if you want only one partition on the hard drive. Then you format the partition - again right click and select format use NTSF - use default allocation size and give the new volume a label (no spaces allowed in the name).

I have the same problem. But I can't format on the right-click. The option is not available. What can I do?

I am having the same problem, I do not get the "format" option with the right click. Did you find a solution?

I have noticed a few people saying that they dont want to Format the slave drive so what to do?
But have not seen a reply.
I am in the same boat & can see the slave in disk manager as local disk but only option is to format it in actions etc
I dont want to do that as only need to get the data from it.
Can anybody provide a solution, pleeze
Someone did say set to cable select, I tried that also & it did not work

Had the same prob.
Using Acronis Disk Director , I simply had to reassign a drive letter to my hard disk partition, it will be detected by My Computer, with all data accessible too!

I just purchased a second internal hard drive and my BIOS will not recognize it nor will 'my computer' recognize it.
I am stumped as to how to get this going.

Any suggestions?

I didn't Have to ask a question. Someone else already did that. One of the answers solved my problem of installing a second SATA HDD and it not showing as a lettered drive.
Thanks everyone for your diligence and your willingness to share with others.

I searched everywhere and everything i saw regarding installing a second sata hd on xp, dealt with installing raid. Finally became smart and reworded my google search "installing second sata hard drive without raid" and this was the first link that google came up with. Worked perfectly. Thank you very much.

All good advice, but when installing a extra drive it will not show up in windows.
my advice is to follow the link and download the software on the site of the harddrive manufactuer;
Such as this link to Western Digital drives site, this will show the drive and format also (may work for other drives)
I have vista and had to set up the install programme in compatibility= right click on install programme / select properties / compatibility / tick box -- run this program in compatibility mode -- I chose win 2000 then applied . start install program etc.

Hope this helps some.

I also have a problem with a WD 1TB SATA drive. However mine isn't even being detected when I go into Windows, when I disable in the BIOS, my PC boots. But its when its enabled, I get an error - auto-sensing slave hard disk drive, strike F1 to continue or F2 to change settings.

I am going to try and install Windows on this drive, but I fear it may be gubbed :(

I bought a western digital internal HD 1TB, i put it in my computer, and it would show up in Computer managment >storage > disk managment

But it wouldnt show up in My Computer.

i downloaded Data LifeGuard from the western digital website but i have vista so it didnt work very well, but i followed these tips and everything worked thanks so much

Right click and properties>compatibility.

after i used this programe it seemed to have worked straight away. I perviously used Computer managment to format the new internal HD but that did nothing.

this programe did the trick> but that was for my model

so use the other part of the link to find what you might need or perhaps there is some other software you can use if you have a different brand. try their website perhaps.

thanks a lot to the person who posted this!
