hard drive error

[whatfor]

when I got my latest computer I partitioned the OS drive into 2 partitions and used the logical drive to store data. I now am having problems with it. When I try to open this drive I get 'M:\ is not accessible. Parameter is incorrect'. The drive is showing a healthy logical drive in My Computer but is inaccessible. Any help appreciated

Post a screen shot of Windows Disk Management.

What is the result if you go to a command prompt, change to the M drive, and enter this command:

dir /s *.*

Do you see a bunch of files flash by, and when it stops, do you see a numerical total of some kind?

when I try that I just get a 'invalid switch' message

With a space after the dir and after the s, but nowhere else?

Or just try dir *.*

A screenshot might help.

no matter which way I try that from the command prompt I get 'invalid switch'

here is a screen shot. the problem drive is M

Uh-oh. That pic shows it as a RAW drive.

I assume you have data on it?

It sounds like a partition table error. Did you previously format M with the NTFS file system? And then put data on it?

It's probably correctable with the right tool.

You might get some ideas here:

Or hope that SIW2 sees this thread.

running testdisk now...could take awhile

Sometimes running a http://www.sevenforums.com/tutorials/433-disk-check.html on the drive with both boxes checked will fix the RAW error, as well. This is the easier solution if it works.

I will give disk-check a try after testdisk has finished running. thanks for the info

What is the current status of the system and the partition that was marked RAW? Any change?
