Has Anyone Had a USB HD get a RAW partition error?

So you were doing a RAW data backup in EaseUS ToDo Backup when the power hit?

It's probably messed up.

Abrupt power loss and electronic storage devices is a nono. If you care about your data, get a UPS. Once it goes RAW there's only a couple of options left, run chkdsk to see if it can recover it or otherwise use a third party tool like Easus to pull data out. It's more likely filesystem corruption than a hardware issue though so after you extract what data you can, you can probably just zero-wipe it and then format it again.

Are you familiar with FAT, FAT32, NTFS. They are file structures or formats that keep track of where the information actually ends up on the physical discs.

Well, if a USB drive starts to physically wear down, or if the power to it is removed at just the right time, ie the middle of a write, it loses critical bits that tell how the whole structure is arranged. The structure is still there, but the boot sector doesn't know how to navigate it.

I was watching TV, nothing to do with easUS, when the power went out.

This is what I'm doing now, which is easUS. This link probably explains the situation better than me

RAW is bit-level. There are no file structures or file systems. RAW is just that, raw.

If you have a partial RAW partition, it's much, much different than having a couple of missing files or corruption in a file system.

OK, that makes much more sense. You're trying to restore the RAW image to a useable format. EaseUS can indeed do that as can DriveImage XML which is my tool of choice.

The safest course of action is to restore the RAW partition to another physical drive if you can.
