Jupyter Kernel Dies Tensorflow Again and Agian
At the time of writing this post I must say that I feel like a hero! That feeling is wonderful y'all know, when someone has a problem with their calculator and non a simple but a HUGE ane and you are able to repair em you lot turn to be that people hero.
Today my friend Avaco12 made a little mistake while installing bootcamp on her iMac, she left her external (200GB) deejay connected, and when Windows asked her where to put the new Partition she accidentally selected her preciousus external drive, when she realized it was already as well late, windows had already destroyed the partition table on her disk. She had 1 HFS parition and 1 FAT. She was crying considering she said she had her unabridged life on that disk, so she asked me for help and I started researching what could I possibly do to repair the disk or at to the lowest degree think her information.
There are plenty of solutions out there, some of them are really expensive, and people on the forums are not very happy with them and then I wanted to look at trivial more than into the issue and I came across this solution called TestDisk which is an Open up-Source Multi-platform solution for repairing deejay partitions. I gave information technology a try and awesomely I managed to set the disk using TestDisk and the pdisk utility.
When I called Avaco12 to tell her that I stock-still her information she was then happy she couldn't stop smiling she told me I was her Hero and and then that's how I felt, the process wasn't easy especially because noone talks about how pdisk works on Mac Os X.
Here's how I did it , hope information technology works for you.
ane.- I downloaded TestDisk from their official site :http://world wide web.cgsecurity.org/wiki/TestDisk
ii.- I opened the terminal and surfed to where I downloaded and unziped TestDisk
three.- I issued the command 'sudo ./testdisk' it indetially promped me to make my final bigger =P, later on doing so It displayed me a unproblematic disclaimer and and so a notice telling me that TestDisk could Log all the activity if I wanted to. I selected Yes and continued.
4.- On the screen it will brandish yous all the Deejay information technology detects connected to your Mac select the i that got damaged partition tables and press Enter. Take note of which bulldoze you selected, in my instance I chosed /dev/rdisk1 (rather than /dev/disk1)
5.- Next screen select the menu Analize, it will probbly brandish you and error telling you the block 0 couldn't be read, just hit enter on the 'Quick Analize' option
vi.- Attending: TestDisk will quickly search for partitions on the disk and display you information nigh it on your disk. Have note of the information information technology will display you, since you'll need information technology to repair the disk subsequently on with pdisk.
Here's a screenshot of what I got:
Note: if you try to repair your partitioning table with TestDisk it will neglect since that office is not nevertheless implemented.
7.- you can now get out TestDisk. The next steps are what distinguish a kid from a Men
viii.- Event the command 'sudo pdisk /dev/rdisk1' (where /dev/rdisk1 should be the same name you lot chosed on stride 4). If y'all type the control 'c' and hit enter information technology will tell you the following:
9.- That'due south completely normal. At present type 'i' and it volition display you lot some affirmations nearly block sizes and such, simply hitting enter:
10.- Now we are going to need the info from Step 6. type the command 'c' and press enter, it will inquire you to type down where your first partition starts, how long it is and how y'all want to proper name it. echo this step for every sectionalization you have.
eleven. Now if you are completely sure you wrote down everything correctly (like I did) merely type down 'w' and hit Enter, It will prompt y'all to ostend merely say yes (y)
12. blazon 'q' to quit the application and go meet for yourself if your disk appears now in Finder. If information technology does, go to Stride 13. else endeavor disconnecting your external hard disk and reconnecting information technology. Later Mac Bone X x.six.7 it is suggested that you restart your motorcar and reconnect the deejay. If this fails endeavor again from step ane. Don't worry about rewriting the partition table it doesn't harm your information.
13. You are a hero, no matter if information technology's your own disk, you lot merely saved your data!
UPDATE:
If yous are having issues with an error message on pdisk saying "the map is not big enough" follow these steps:
Earlier the analyze step go to GEOMETRY and change the sector size according to the following table:
| Volume Size | Default Block Size |
| <=256 MB | 512 bytes |
| 256 MB <= 512 MB | 1024 bytes |
| 512 MB – ane GB | 4096 bytes |
Now go back to the Analyze step continue from there. Thanks to Stan Alien for the heads upwards.
Congratulations, and I hope this information is usefull to you lot now call back to backup your data! Personally I recommend Backblaze.
You can buy me a potable if yous'd like to share your joy 🙂
cheers !
