My 1 TB SEAGATE HDD is connected to my PC via SATA along with all other drives. It only shows 3.9 GB and asked to initialize the disk which I did but it said “The request could not be performed because of an I/0 device error” then I tried the disk part still didn’t work and gave the same error there. I also checked if it needed drivers, but they're updated apparently. I feel like the HDD is only showing a partition of the drive to my computer. It shows it is online and can create a 3.9 GB disk through AOEMI software. How do I view the whole TB?

The easy answer is that the disk is bad, replace it.

The more detailed answer is that you might find this disk was once formatted to a type that Windows cannot work with.

New WD and Seagate 1TB drives are starting at $30 on Amazon, free shipping. Probably not worth the trouble to put a lot of work into this.

Option #2.

Use Powershell to run the Get-Disk cmdlet and the Get-Volume cmdlet

Here is how to do that:

A Seagate drive which reports a capacity of 3.86GB is displaying the symptoms of a head/media fault. Normally the drive would retrieve its Identify Device info from the reserved System Area (SA) on the platters. If the drive cannot reach the SA, it reverts to identifying itself using an Identify Device template in the ROM on the PCB.

i would be checking the connections to the drive. maybe replace the sata cables. try a different sata port. Make sure the bios is not set for some raid sata mode. Some sata ports on some motherboards have special functions. (most often the first or last port. I would skip those ports)

guess, i would make sure the machine is in high performance mode. just to avoid the case where windows told the windows to sleep the drive and can not wake it up due to old bios version.

i would think a i/o error would be a bad data cable connection or maybe the drive not spinning.

note: reading about the problem, looks like corrupt firmware that would require repair using special tools
