Changing it from the default partitions to ZFS definitely broke something, but you should still be able to recover it. I would personally put the drive back into the computer and boot from a Linux Live USB or Windows installer USB. USB enclosures aren't always effective on recovering a bad drive.
As I asked before, if booting internally, does it show up in the BIOS? If it doesn't, don't expect an OS to recognize it. However, if it does, you should be able to recover it.
There are a lot of websites with steps to recover the drive. Assume that adding it to your ZFS array completely altered the boot record, possibly changing it from UEFI (default for current Windows versions) to MBR. From Windows, you'll use diskpart. You can get a lot of information from it and run some commands to clean the existing configuration and start from scratch.
I did mention it but my last post was again very cluttered.
The disk does not show up in the BIOS. Booting from a live USB did not allow me to see it in any way. (I tried gparted on Ubuntu and diskpart from the windows shell)
When connecting the disk to a Windows PC using an external case the Disk Management takes quite long to initialize the virtual disk service prompts me to initialize the disk. No matter what i try to initalize it to i get the error
Code: Select all
The request failed due to a fatal device hardware error.
accompanied by Eventlog entries with the ID 154 stating:
Code: Select all
The IO operation at logical block address 0x3f00c000 for Disk 4 (PDO name: \Device\00000151) failed due to a hardware error.
and
Code: Select all
The IO operation at logical block address 0x0 for Disk 4 (PDO name: \Device\00000151) failed due to a hardware error.
*UPDATE*
I played around a bit more. The DCOM Server Service crashes from time to time but i do actually see the disk with diskpart.
Code: Select all
DISKPART> lis dis
Disk ### Status Size Free Dyn Gpt
-------- ------------- ------- ------- --- ---
Disk 0 Online 931 GB 1024 KB *
Disk 1 Offline 223 GB 0 B
Disk 2 Online 465 GB 2048 KB *
* Disk 4 Online 0 B 0 B
And i'm also able to select it.
Initial attempts to create a partition or do anything to recover it have been unsuccessful throwing the following error:
Code: Select all
DISKPART> create partition primary
DiskPart has encountered an error: The request failed due to a fatal device hardware error.
See the System Event Log for more information.
I moved back to try other ways. I can see the Disk in the device manager too so my hopes are up again!
It's called
Jmicron Tech SCSI Disk Device in there.
