Don't use Windows 7 legacy Backup on Windows 10
« on: February 23, 2016, 10:46:36 pm »
Long story short; about three months ago I wanted to use said program to create a backup of my Windows 10 machine. It failed again and again, and a thorough chkdsk revealed that every single cluster of the external HDD it was writing to was marked bad.

Today I managed to get myself to have a look at it. Interestingly, a little digging with diskpart made me discover that -8MB (yes, negative 8 megabytes) was free for usage. I erased the partition and did a full format, taking about 6,5h. So far I seem to be able to create txt-files on it again, another chkdsk will be done to confirm the disk's functionality.

I now believe Windows 7 legacy Backup raped (most accurate expression) the poor disk's MBR.

tl;dr: Window 7 legacy Backup destroys external harddisks on Windows 10.

Thanks :P, my computer seems to be a little drunk sometimes. Recently, an update failed that prevented me from using the start menu, but this failed update had symptoms similar to an imminent harddisk failure. Spent the whole afternoon transferring files and staring at chkdsk C: until I did a system restore. The only reason I tried system restore last is that if my disk would actually fail, I wouldn't be able to forgive myself for losing 500GB of data that I had gathered over the last six years.

Forgot to mention I tried programming my own simple backup utility. Kind of put it aside because of recent school projects.

That sucks Brentmaas. To be honest, though, I didn't know that Windows 7 legacy Backup existed until tonight. Is it built-into 10?

Also nice to see you again brentmaas.

It was a fresh disk, so no, fortunately :).

Yeah it comes with Win10, probably for simplifying upgrades.

Also nice to see you again brentmaas.
I was lurking here all along  :ninja:.

The name sounds like it's to downgrade back to Windows 7.

Wow, that's harsh. Do you think it was a bad disk to begin with, or is W7LB really at fault?

My epic quest for the receipt continues. I'll just have it replaced with Intenso (the manufactorer) when I find it.

"Watch out!", they cried to Brent, as the dust dragons encircled his head, preparing to attack his precious respiratory system. Brent quickly glanced, then attacked them with a vacuum cleaner.... The battle was short, but fierce. Brent had won. Relieved, he headed to the Mountains of Cloth to continue his quest for the Receipt of Disks...

I cannot confirm this at all. I did successful backups with this and my external Toshiba HDD is just fine. It just creates some container file and does not mess with the MBR at all.
