Sep 1, 2013
Category: Tips and Tricks

USB Flash Drive recovery Today I found that I can’t access to my 8Gb USB flash drive. I can find it in Finder, but the System gets stuck while accessing to it. What to do? If you want to recover data from a USB flash it’s better to stop reading this post now and continue googling “USB flash data recovery” or something. Here’s a step-by-step instruction how to make your USB flash drive work again under Mac OS X.

1. Open Terminal and go to /dev

$ cd /dev

2. Now it’s time to find your flash drive in /dev. Typically it’s /dev/diskN where N could be 0, 1, 2, 3, etc

$ diskutil list
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *121.3 GB   disk0
   1:                        EFI                         209.7 MB   disk0s1
   2:                  Apple_HFS Macintosh HD            120.5 GB   disk0s2
   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3
/dev/disk3
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *8.1 GB     disk3
   1:                        EFI                         209.7 MB   disk3s1
   2:       Microsoft Basic Data KB                      7.9 GB     disk3s2

OK! It’s disk number 3, i.e. /dev/disk3 Remember the name of partition (it’s KB in my case). Your flash drive is mounted as /Volumes/NAME Continue reading »


How to add Java sources and docs to your JDK on Mac OS X

Every time I setup a new Mac OS X virtual machine with Java on board I can’t find java sources (src.zip or src.jar files). Here is a short instruction how to setup JDK with the sources and documentation on Mac OS X.

  1. Go to https://developer.apple.com/downloads and sing in.
  2. Search for ‘java developer’ or simply click https://developer.apple.com/downloads?q=java%20developer
  3. Choose the latest build labeled Java for OS X 201X-0YZ Developer Package where X, Y, Z may vary.
  4. Add this JDK to your IDE as you usually do. If sources are not attached automatically, attach them manually. Here is the path to src.jar
    /Library/Java/JavaVirtualMachines/1.6.0_XX-XXX-XXX.jdk/Contents/Home/src.jar

    where XX may vary from version to version.
