Pulling the cord is, of course, a bad idea. But seldom does it cause the drive to lose partition information unless you were re-partitioning it when the plug was pulled. Certainly it is possible. But the more likely situation is that any file in the process of being written is likely corrupted. Less true for Linux if you were using journalling file system (e.g. ext4).

The real question that needs to be looked at is what specifically is actually damaged. I would start by loading a live CD/USB of something like ubuntu. Then the Disk Utility can look at the disk and tell you how it is partitioned and what the SMART data is for the drive. To look for file corruption you could use fsck (file system check) but I can't tell you from here how to use it. You could also download Spinrite from grc.com. That is a well known program that boots FreeDOS from the CD and tries very hard to recover from disk problems. An oldie but a goodie.

I have a raw hard drive. It is a windows machine but I also have some Linux Computers. It appears that if you pull the electrical plug from your computer, it could cause your hard drive to lose hard drive partition information.
I am not sure if the same can happen to a Linux computer, so I want to find what is available just in case my files disappear on my Linux machines.
My research has found that some software claims to be able to solve lost file problems on both windows and Linux computers.

I have no idea how good these application are?

Recovering deleted files is also of interest to me.

Thanks

Mike, we need some information to understand the question. Is this a totally wiped drive, one with some problems, or just deleted files that you are asking about. Tell us you motivation so people can give valid and appropriate answers (other than restore from your backups).

Does anyone know of software used to recover files in Linux and Winlow systems.
I am looking for software that will work on both operating systems.
Thanks for any help.
