Hello guys and girls! I 've accidentally deleted some initial portion (little I think) of my drive through the following command: openssl enc -aes-256-ctr -pass pass:"$(dd if=/dev/urandom bs=128 count=1 2>/dev/null | base64)" -nosalt < /dev/zero > /dev/sda The following partitions existed prior to my fault: sda1/2 (Windows) - about 100GB sda3 (Extended) - about 100GB sda4 Veracrypt - about 700GB some Unallocated space With the above command I wanted to fill with noise the sda3 partition, but due to a mistake while typing the number 3, didn't reach the command, so as soon as I noticed it (pretty quickly) I hit CTRL+C (about 1 sec after the initial ENTER). What I 've done already: 1) Run gpard /dev/sda with the following output after 24+ hours of the command running: Begin scan... Possible partition(DOS FAT), size(10mb), offset(6720mb) Possible partition(Windows NT/W2K FS), size(0mb), offset(31042mb) Possible partition(Windows NT/W2K FS), size(3mb), offset(33462mb) Possible partition(Windows NT/W2K FS), size(3mb), offset(33466mb) Possible partition(Windows NT/W2K FS), size(3mb), offset(33469mb) Possible partition(Windows NT/W2K FS), size(3mb), offset(34282mb) Possible partition(Windows NT/W2K FS), size(0mb), offset(38780mb) Possible partition(Windows NT/W2K FS), size(100767mb), offset(50486mb) Possible partition(Windows NT/W2K FS), size(953866mb), offset(953867mb) * ** Fatal error: dev(/dev/sda): seek failure. 2) Run testdisk with the following outputs: Intel/PC partition option prior to analyzing Non partitioned media option prior analysis So the first scan only came up with: Disk /dev/sda - 1000 GB / 931 GiB - CHS 121601 255 63 Partition Start End Size in sectors Linux 12858 253 4 24340 40 20 184444928 Structure: Ok. Use Up/Down Arrow keys to select partition. Use Left/Right Arrow keys to CHANGE partition characteristics: *=Primary bootable P=Primary L=Logical E=Extended D=Deleted Keys A: add partition, L: load backup, T: change type, P: list files, Enter: to continue ext4 blocksize=4096 Large_file Sparse_SB, 94 GB / 87 GiB so that should be the Extended Linux partition (that is sda3, before sda4) and the second one with those (among other little FAT partitions): P NTFS 6436 37 34 19282 67 17 206372864 Structure: Ok. Keys T: change type, P: list files, Enter: to continue NTFS, blocksize=4096, 105 GB / 98 GiB P ext4 12858 253 2 24340 40 18 184444928 Structure: Ok. Keys T: change type, P: list files, Enter: to continue ext4 blocksize=4096 Large_file Sparse_SB Backup_SB, 94 GB / 87 GiB 3) Run MiniTool partition recovery option & EaseUS one, through mounting the disk to Windows pc, with the scans not showing the veracrypt partition, but one of the (MiniTool) showing the above linux one (87.95GB) My question is, do you know any possible way that I should proceed in order to recover the Veracrypt partition (previous sda4)? In the end thats the only data that I care of. I look forward to your insights, as I am available for any clarifications! Thank you in advance for your time!
I have seen a few things people have made with old hard drives? Tesla turbines being among the coolest. Lately I've been getting into locks and whatnot and I thought it might be cool to make a wheel pack for a combination lock from some hard drive platters. What are you doing wit your had old hard drives?
I wrote a program today that will read a physical drive directly. I read the first 50,000 bytes into a txt file, starting at sector zero. I see some text, but also a lot of graphics characters and symbols. I have googled what this could be, but haven't really found anything. I know its some sort of encoding of my data, but I'm not sure. My hopes are that its something that can be made sense of. I have seen some of this from assembly, however I'm still not sure what I'm looking at. I will post some of the out put below. So the question is, what is it. If someone could give me some insight or a link, I would be thankful. I was trying to take a look at the mbr and was not expecting the weird graphics. I'm mostly curious if this can be converted to something comprehensible. Thanks, Beetle Excerpt: Sorry for the excerpt being so large.

Am having a storage issue with my Dell PowerEdge 840 which is my web server/file server. The documentation for the server says that each of the four sata ports on the motherboard can only support hard drives up to 1TB in size, and i confirmed this by reading posts of people having issues with larger drives no matter what OS their using. Can installing a sata controller that supports larger drives bypass this issue. Thanks, in advance
