Question

Posted

Hi guys, this is the second time this is happening. The first time around, I lost 400+ GB of static data but I cut my losses, formatted the drive and carried on as usual. This evening, the same thing happened.

 

A partition, E:\ deleted itself and along with it, the data it had (of course.)

This is what it looks like:

What could be the likely cause of this? I searched all over the internet for a cause but came up with nothing.

Any help would be nice. :(

 

Thanks.

Run CrystalDiskInfo on the drive and post the results.

Weird, might be time to just replace the drive. Have you tried a new cable?

Think that would work? Will check it out.

 

This might seem unrelated but this happened the night I changed from MBAM free to Premium (just for that Hyper scan feature). I don't know if I should reinstall my OS. Seems futile to me. 

 

Worst case scenario, I'll get a new drive. Sigh. My monies.

Never ever heard of this - partitions just don't delete themselves. When did it go missing? After a system crash, after a reboot?

Why do you not just have at most a C and D partition.. I don't really understand the reason for creating your OS partition and then 2 other data partitions? Why? Your E was clearly in an extended partition as a logical drive.

What does your eventlog say about it?

I used to have two partitions - OS and a data partition. Needed to run Linux and so, created the third partition. After I finished work with that, I just kept that as it is for no solid reason. 

 

This happened after a reboot.

Does anyone else have access to your machine?

Have you tried TestDisk? It can be used to find "lost" partitions.

 

Try and see if it can find your partition first and get the data out?

This wasn't done by a third person. This happened after I rebooted my system as I was cleaning up my program list, etc. I don't know if these are related.

Right now, more than getting back the lost data, I want to find the cause for this to prevent it from happening in the future.

Does this give any clues? 

 

"A problem has occurred with one or more user-mode drivers and the hosting process has been terminated.  This may temporarily interrupt your ability to access the devices."

EDIT: This has something to do with that stupid Samsung Galaxy Tab 2 I have plugged in (educational). Nothing points towards the partition being deleted. 

Mhm.

Partitions might not delete themselves, but are you using it across other platforms? It's stupid, but I've already learned that Linux might decide to play around with permissions if you're doing that - especially with NTFS or ExFAT- in a way that it screws with the headers.

I hope you haven't wiped the partition. The data is potentially still recoverable. I'm currently backing up an external HDD to a different one for just such a reason. I need to wipe the first drive to make it compatible again; this time I'm going UDF for a filesystem, but that's my choice.

^ In all my years of working with dual-booting Linux and other systems, I have never heard or experienced it changing permissions outside of the partition that it exists in. NTFS and ExFAT works well with Linux.... so much that removable hard drives can get swapped from Windows to Linux systems and function perfectly. If the partition is a Linux-based file system such as ext, ext2, ext3, ext4, or ReiserFS, Windows will not see that file system at all.

Here is the thing, if the OS thought there was a E logical disk, and now it can not find it there would be something in the event log. If you created one and then deleted one - it would be in the event log.

Look through your event log at the time you rebooted your machine and noticed it was gone. If it was me I would deleted the extended - expand the current data part into the now unallocated space and restore your data from your backup that was on that 400gb part.
