lost ext4 partitions

#1 Post by robbingTM »

Hi all,
I had a spare server with a bunch of storage so I thought I might as well get Ubuntu going on there and use the storage for farming CHIA.
I formatted the drives and created Ext4 volumes and got to plotting.

A few months later, I wanted to use the PC for a test environment so I added another HDD and installed Windows 10 on there and had 1 for Ubuntu, and another disk for Windows.

When in Windows, I wanted to keep the CHIA going so I installed Chia blockchain app but obviously with the partitions on the HDDs being Ext4 Windows didn't natively see them.

I went and took a look in Disk Management and it popped up saying "Do you want to initialize the disks?"
I STUPIDLY said YES. BOOM, within 1-2 seconds all my CHIA plots were gone.

So I calmly went back into Ubuntu and tried to run TestDisk to recover the partitions, but I'm having difficulty in doing so. I have done nothing to the disks except say 'yes' to Windows initialization, so I know the data should still be there, just Windows did it's thing and re-wrote the tables headers or something.

When using TestDisk and analyse the disk, it defaults to type 'none'. It finds the partition / volume named CHIA009 but it disables write because the disk type is 'none'. I'm not sure how to get around this. Could anyone lend a hand please? This isn't critical data but damn, it took me 2 months to plot 722 plots so I'd really appreciate a way to get these back without needing to start over. TIA!

I attach the logs, including the full scan it did. Unfortunately it is clouded somewhat due to old partitions being remnant on there too.

Re: lost ext4 partitions

robbingTM wrote: ↑05 Jul 2021, 12:38 Hi all,
I had a spare server with a bunch of storage so I thought I might as well get Ubuntu going on there and use the storage for farming CHIA.
I formatted the drives and created Ext4 volumes and got to plotting.

A few months later, I wanted to use the PC for a test environment so I added another HDD and installed Windows 10 on there and had 1 for Ubuntu, and another disk for Windows.

When in Windows, I wanted to keep the CHIA going so I installed Chia blockchain app but obviously with the partitions on the HDDs being Ext4 Windows didn't natively see them.
This is unclear. If there is no file system that windows understands, windows will not write there unless you partitino and format it.

I went and took a look in Disk Management and it popped up saying "Do you want to initialize the disks?"
I STUPIDLY said YES. BOOM, within 1-2 seconds all my CHIA plots were gone.

So I calmly went back into Ubuntu and tried to run TestDisk to recover the partitions, but I'm having difficulty in doing so. I have done nothing to the disks except say 'yes' to Windows initialization, so I know the data should still be there, just Windows did it's thing and re-wrote the tables headers or something.

When using TestDisk and analyse the disk, it defaults to type 'none'. It finds the partition / volume named CHIA009 but it disables write because the disk type is 'none'. I'm not sure how to get around this.
Do you remember your partition table type? What's the size of the drive and it's emulated sector size?
You might try setting it to GPT.

Furthermore you did not specify what kind of analysis you did and if you used the "p"-key to check the content of partitions that hade been found.

P.S: By error I suppressed the second part of your posting. Maybe Christophe Grenier is able to repair that fault.

Can you try TestDisk, partition type: None, Advanced, List ?
If you can see your files, try "fsck.ext4 -b 98304 -B 4096 /dev/sda"

Yea Windows didn't recognise the volumes as anything so it offered to initialize them like they were new disks. I didn't realise this would alter them like it did.

I have no idea sorry - I used thre built in GUI for Ubuntu to create them. Does native / default Ubuntu EXT4 tell us the answers here at all?

I'll give this a shot, and report back my findings. thx for the advice
