Click on OK to Initalize Disk.

How did you format it?

Try this: Right click on where it says "Disk1" in your Disk Management and see whether you can initialize it.

GEWB thanks for the tip but it will not test the hdd

FliGi7 i did it by opening it in my computer right clicking and going format ( full not fast)
whs thank u for the tip but did not work got the same error message as in photo 3

Did you try the Buffalo Tech Forum? One similar post got this moderator reply:

"CRC errors typically indicate HDD failure. Make sure that you have a backup, then reformat the drive (NTFS is a good choice). If you continue to get the errors, you should get a replacement."

I know it'll take quite some time, but you could try a low-level format. It'll show you if it encounters errors during formatting. This might take some time.

Hello.


In diskpart from an elevated command window type these commands.

That should initialize the HDD.

diskpart

select disk 1

online

exit

exit

If you want to wipe the HDD have a look at this tutorial at the link below
