WDBlue detected only 30MB

TechRicalx

I was installing windows on a  WDBlue disk that i had bought 2 years ago but didn't end up using it much and it showed up in the windows installer as only 30MB and in the BIOS as 0.0TB so i could use some help on this.

PS I had a backup on it once and it worked fine

Maybe it's just not partitioned, you can lose data if HDD is kept without power for a long time...

Enter command prompt,

diskpart

list disk

create partition primary size=numberinmegabytes

i'm not worried if the data is missing or corrupted it's just that it doesn't recognise it as a 1tb disk.

wouldn't a disk be recognised as it's full capacity even if partitioned?

Windows might not detect it if it's formatted the wrong way, if you don't care about the data you can re-format the drive as NTFS

If you can't even find it through the diskpart utility, then it might be hardware to blame...

Not necessarily, no. You have to format it.

The Windows Installer should be showing the full volume size and any partitions that are on the drive. Even if it cannot read the partition it can still detect it exists. Besides which OP said the drive shows as 0TB in BIOS.

The only suggestion I would have is try a Low Level Format but you have to be really careful here. If BIOS is reporting the disk size incorrectly any tool you run on the disk might try to format the disk using incorrect sector & track values which could really screw the thing up.

 

I'd suggest you unplug all other drives before you do anything (you don't want to LLF the wrong disk) then grab something like Hirens Boot CD, burn it to a disc or flash drive, boot from it and run a LLF tool. Check the drive is being reported correctly before you run the format. Edit - I should add that a LLF on a 1TB drive will take A VERY LONG ASS TIME, like be prepared to wait over half a day.

 

Its also possible that the drives firmware is somehow messed up, the only way to solve this is to buy a dead IDENTICAL drive, swap the PCB over and hope the other drive didn't also have a PCB issue.

it's probably the disk geometry, the cylinders count like to be corrupted to "1", or some small number, for some reason.

Check it with testdisk. if the cylinders count is below 10, then that's the problem.
