I got a new hard drive and it will not recognize the HF207 screen. The shown screen size is normal size, not the whole wide screen size. What do I do?

You can access either through the TV's remote, or the cable box remote picture settings for choosing picture size (i.e., normal, wide, stretch, wide zoom, etc.).

Ad? Turn off "store" or "display" mode in menu. Look for picture size or "aspect" in menu. Remote should have button for "Size" or something.

Change the screen resolution in the Control Panel for the Display.

Click Start/Control Panel and look for Display or Appearance and Personalization. When the Display opens select the Settings Tab. Change the Resolution by setting it up higher, click Apply then click OK.

You could Right Click on an open area on your desktop and select Properties. When the Display opens select the Settings Tab. Change the Resolution by setting it up higher, click Apply, then click OK.

looks like you ll have to reset motherboard re-install OS you might be able to do it at a cybercafe,youll need OS disk

1) Power your wide-screen TV on and turn to a channel that is displayed with bars on the side. You need to leave this channel on to ensure you have properly adjusted your wide-screen TV.

2) Find in your TVs settings where you can "stretch" the picture. Refer to your wide-screen TVs owner's manual for specific instructions. Some TVs may not refer to this adjustment as "stretch." You will be able to find all the information your looking for in the owners manual.

3) Adjust settings back to normal if you want to watch a program shown in 16:9 format. Keeping the screen "stretched" will cause programs shown in 16:9 format appear zoomed in, making the picture look really different.

Yes it should recognize such small drive. Note that the partitions on the drive will affect how big drives are shown.

If the drive is partitioned into two 10GB parts then you should have C: 10GB and D: 10GB

Note that if the drive is partitioned not to use the full capasity then the capasity it is partitioned to will be shown instead.

Also Note that computer hard drives the capasity is not accurate presentation of the GB available. it will always be somewhat less than the reported size, for example 1000GB disk is shown as 931.50GB
500GB disk is shown as 465.76GB and so on.

see picture:

The driver that you are using for your video card doesn't support the resolution of this monitor probably.

If the drive hasn't been formatted, that is normal. On some systems, you also have to force the BIOS to recognize the drive by entering the BIOS setup (check with Sony or manual to learn the key needed). Once you know the proper key to tap at power on (it varies, sometimes F1, F2, Esc - who knows?), you will be presented with a simple text screen with a number of different selectable items. Choose 'Set factory defaults' and the BIOS should look for the drive and set the parameters for you. If that still doesn't work, check through the other BIOS items and you should find 'Detect fixed (or hard) drive.'
Sometimes installing a larger drive than the original can cause problems and if the BIOS is older, it may set the drive parameters of the original drive and ignore the excess capacity.      

First I had to reseat one of the drives which had worked loose and become unseated during shipping. Then I had to format the hard drive and finally I had a 1TB external hard drive I could use. The light is still red.

the original image size was probably recorded in 4:3 aspect ratio...meaning your widescreen is a 16:9 ratio size screen and is stretching it outwards to fill the whole screen. If you want the image to look normal.. ie. not short and fat people.... you need to change the picture size in the settings from widescreen 16:9 to normal 4:3 tv in the settings menu most likely...Also most remotes will/should have a button for that.
