Today I had a powercut and unRAID should have shutdown as normal with the signal from the APC UPS. On unRAID I have a Windows 7 Pro VM running that has a full HDD passed to it (4TB Purple for CCTV). The CCTV software has been writing to the drive so it's good.

 

I'm guessing the VM was either forced to shutdown or just switched off when unRAID went into shutdown mode.

 

The problem I have now is that the VM has started up but the E drive (4TB Purple mentioned above) is asking to be formatted. Device manager is showing it as raw and asking to be formatted.

 

Any ideas? Is this an unRAID or Windows issue?

 

(Note: not to stressed if I have to format the drive again but I'd like it not to happen again)

How have you passed through the drive? by disk name (/dev/sdx) or by ID?

If its by name, it could have grabbed a different disk on startup if unraid decided to name the disk differently for whatever reason.

Worth checking your xml against the disk name in the GUI to make sure.

I have it listed by ID
