Problem in recognizing HDD data!

Hello, out of no where this two problems happened to me:-

1. when i connect my 1 tera HDD, it shows in my computer, but;
it's shows that its only 457 GB & it's completely empty!
also i can't access it or do anything about it.
one more thing; i remember that it had at lease 700 GB of data.

2. also when i connect my 4 tera HDD, nothing happens;
it even doesn't show up in the Disk Management.
with this one i tried USB & eSata cables, neither have worked.

* PS: both of them have electricity power supply,
& when i connect to the computer the sound coming of them changes:
it says that they know that they are connected to the computer!!!!!!!!

Hi

When you connect these via SATA cables, can you see them in the BIOS?
