df 925

Hi just wanted to close this out. I was able to use an old Dell E6420 laptop, and use Ubuntu 18.04 trial, and install ddrutility. ddru_ntfsfindbad /dev/sdc mapfile reported an error about unknown partition, but I think thats because I did not use the -i option to specify the correct partition. I was able to use ddru_findbad /dev/sdc mapfile and that was successful Scott, so thankful for your excellent tool and your help Best, DF

Just for anyone that tries this on RPI3 and Raspian: Its a 1TB partition, and my RPI3 only has 1GB RAM. I bumped Raspbian to 2G swap, but it appears to still run out of memory running ntfscluster. Inode 633741 is an extent of inode 629525. Inode 633742 is an extent of inode 629525. Inode 633749 is an extent of inode 631663. Failed to malloc 4096 bytes: Cannot allocate memory Couldn't read the data runs. With the larger memory I'm trying to run ddru_findbad /dev/sda mapfile -Q this worked, however...

again greatly appreciate the insight. On Rasbian, I just used apt install ddrutility. I'll play around with the makefile today and hopefully that will be it. excellent tool, and appreciate the work you put into it! Not too many errors, only 3 errors 4k in size, but last time I ran ddru_findbad on the same raspberry pi, it locked up, so I gave up.

To branch this discussion, is there anyway to use the MFT and the mapfile to do the same? That way I wouldn't have to connect the USB to anything? Thx DF

The original hdd is from a dell xps. I used gddrescue from systemrescue to clone it to a USB drive on the same machine. Then I used a Raspberry PI 3 with Rasbian to run ddrutility on that same USB. Attached is the dmesg from the Rasberry PI to run ddrutility. I used apt install to get ddrutility, so I'll need to figure out how to run a make, or maybe do it on another OS? Thanks again! DF
