Windows 10 - Simple Storage Space

#1 Post by AtoD » 19 Apr 2016, 21:25

Hi,
I am trying to recover a Windows 10 simple storage pool. I tried to remove a failing disk from the pool of 4 disks. The disk in question stopped with 0.02% data left in the removal process. At some point I over wrote the partition and can no longer retire the disk from the pool. Using TestDisk I did a scan and 4 deleted partitions were found. 3 MS Data partitions and one listed as MAC HFS? See attached picture.
I am not sure how best to proceed. Specifically how should I identify the partition to recover to restore the original partition?
An insights are greatly appreciated.

You haven't posted a screenshot of the actual partition content... Copy/paste the testdisk.log file is a good idea.

If you didn't wrote about using this disk on Windows, I would have assume the first partition found by TestDisk to be the good one but it's a Linux ext4 filesystem. You can use 'p' to list the files from this partition.

Hi,
Thanks for the reply.
Please see screen shot and log file below, It was filled with read errors, I've removed the bulk of them and replaced with ... to save space.

Kind regards, J

Re: Windows 10 - Why Mac HFS on my external hard drive?

#4 Post by Xhdjunkie » 30 Sep 2016, 07:31

Hello,

Why would I find a "Mac HFS" partition on my windows formatted external hard drive? Like you did. Is that normal?

One day a few years ago, my drive ceased to work on my pc. I am on my second week of analyse + deeper analyse for a 4tb drive. Did someone in my house plug it into their mac and it bugged out?

My windows 10 machine will not recognize the drive at all, which is why I started testdisk in the first place. Should I plug it into a friend's mac and see what happens?

Egads. I have my entire dvd collection backed up on it and want to be able to access it all again. I sold my discs for rent in the meantime. Any ideas? Have you noticed a post about this that I missed?

The signature for HFS filesystem is not very reliable. False positives are possible.

Xhdjunkie, without the log file or at least a screenshot, it's difficult to know why the scan is so slow
- Presence of bad sectors. Do you see error messages ?
- Some people search partitions inside a partition, it's totally useless and time consuming.
