new SATA drive recognised in BIOS not by win 7

Hello -
I have two drives on an old computer.  I've just removed a SATA drive with MOLEX connector (power) , and replaced it with a new seagate drive , using a MOLEX to SATA adaptor.

OS (win 7) and programmes are on a (rather full) Maxtor 80 gb scsi hard drive.
docs were on the second drive, now replaced but inaccessible (for formatting etc)

The drive is new and will need to be formatted.

Now the new drive is recognised in the BIOS / Setup screen, but windows does not show it in the My Computer screen.

Phoenix bios read thus:

IDE channel  0 master  =  [none]
IDE channel 0 slave    =  [Maxtor 65Y080L0]
IDE channel 1 Master  =  [Artec WRR-52X]
IDE channel 1 slave   =  [none]
SATA channel 0 Master  =  [Seagate ST31000340NS]
SATA chananel 1 master  =  [HL-DT-DVDRAM, GH24]
sata CHANNEL 2 MASTER  =  [BONE]
sata CHANNEL 3 MASTYER   =#  [NONE]

aUTODERTECTION ON SEAGATE DRIVE SHOWS IT UPO AS
CAPACITY 1000 bg

CYLINDER    65535
HEAD   16
PRECOMP    0
LANDING ZONE   65534
SECTOR    255

So I need to get windows to recognise it.

ON a further note -
the intention here is to pass the PC on to my son who intends to reformat or remove the maxtor and run linux.  May this have any bearing on my next move?
Either way, I'd really like to know why it doesn't show up in my computer since it's recognised by the BIOS.

Kind regards,

Alex

New hard disks usually don't show up in "My Computer".
Start > Run > diskmgmt.msc
Now you should see the drive, and you are able to make partitions/format.

"The drive is new and will need to be formatted."

What makes you think that? A new disk usually comes unpartitioned, with no file-system on it. That means you certainly first have to create one partition, then create a file-system (NTFS), and format that and assign a drive letter to it. Only after that has been done will you be able to see the drive letter you assigned to it when you open your "Computer" icon.

How that is done is explained in Kimputer's comment above.

Oh, sorry about that, in my haste I thought I read "will NOT need to be formatted".

New drives usually need to be initialized and a partition/file structure put on them before they can be used in Windows. As noted by Kimputer have a look in disk management on Windows - you should see the drive listed as RAW/Unformatted space - right click on this to create a new simple volume. (If it asks you to initialize the disk click yes or ok).

Thanks, simple information but not apparent to the uninitiated.
