Well thats an interesting way to lose data
« on: September 11, 2010, 03:30:48 PM »
I've found a new way to lose data -- have an OS convert an existing physical partition into a logical partition.

After discovering that over 300 GB of anime disappeared I rebooted into a live copy of Ubuntu. I went to GParted to find the name of the partition in question. It was listed as being part of an extended partition. I did not set it up that way and a month ago when I did this (a ruetuine check) it was still its own partition. The data was there last week. I was using some of the files as test files for my new monitor.

I fsck'ed the parition, and there were no problems. Where did my shit go!?

[edit] I should mention I didn't do that intentionally.

[edit2] If you can suggest some file recovery software, please do so.

i kinda laffed at this, but its really not a laughing matter.

I had basically the same thing happen to me a while back, luckily it was a computer that didnt have anything important on it, just some songs.

Yeah. PhtoRec seems as if it may work. It recovered some. We'll see.

I don't have enough free disk space to recover the data, but I ordered a 1.5 TB drive. It should be here By Wednesday.

If anyone has any good suggestions for file recovery software please share.

GetDataBack by Runtime Software. There are separate versions depending on if your drive was FAT or NTFS.

I made this thread a while back. Take a look. Some of the programs I used may help you.

Well, I got a new HDD in so I'll recover my files tomorrow. I'm too busy today.

This thing happened to me once, but with my ≈100GB of perfectly sorted and tagged music colection. R-Studio was the only software that got the data 99% back the way it was before.

PhotoRec is a joke. It got about one sixth of the total amount lost (16.6%). I'm going to try something else.

[edit] R-Studio, which I have used before, won't read from an ext4 partition.

Versions >5.0 do support ext4 partitions.

Quote from: R-studio website
R-Studio is a family of powerful and cost-effective undelete and data recovery software. Empowered by the new unique data recovery technologies, it is the most comprehensive data recovery solution for recovery files from FAT12/16/32/exFAT, NTFS, NTFS5 (created or updated by Windows 2000/XP/2003/Vista/2008/Win7), HFS/HFS+ (Macintosh), Little and Big Endian variants of UFS1/UFS2 (FreeBSD/OpenBSD/NetBSD/Solaris) and Ext2/Ext3/Ext4 FS (Linux) partitions. It functions on local and network disks, even if such partitions are formatted, damaged or deleted. Flexible parameter settings give you absolute control over data recovery.

Its probably too late now. I'll give it a try, but I doubt I'll get any more than before. Downloaded a shit down of crap this week end so chances are the data was over writen.

I'll give it a try any way.
