320GB HD change and recognize as 2TB Problem
Hi,

I would like to ask if someone experince this problem on a Hard disc. I had a 320 GB WD Blue 3.5 Hard disc. When i plug on my PC BIOS detect it for a while and dis-appear. Luckily sometimes i can check it on a bootable CD or attach on other LINUX PC but for a while it will dis-appear. As if you try to access the HD it will disappear from OS system even in BIOS. This is the results when i check the HD on linux using Fdisk. To my surprise the 320GB detected as 2TB.. HOW come it become to 2TB.

Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.

Disk /dev/sdc: 2199.0 GB, 2199023255552 bytes
255 heads, 63 sectors/track, 267349 cylinders

I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0993f2aa

the Disk Identifier change when i force to format it with fdisk option.. It means the disc is still accessible or something im missing..i already tried gparted or any tools related to HD or Filesystem (UBCD). But no success.

Maybe someone can give some ensights or opinion or any things that will help recover my HD or should i throw it on the garbage.

Firstly, I assume this is a x86 issue? Since you're running Linux it almost certainly is.

What motherboard is it?

First thing to check is whether the motherboard BIOS is supposed to support a 320GB disk? Do you have similar/larger disks on the system already that work?

Is this a SATA disk?

Check that you have the latest BIOS version for your motherboard.

Please post the full make/model of the disk drive.

Also, could try strapping down the negotiated transfer speed................

Why would Linux be a clue about the architecture? I have production Linux servers running on Alpha, IA64, Sparc, and ARM.

If it is usb, power savers sometimes turn off ports.
