Linux Format USB Drive

Here’s how to format a USB drive on Linux.

Plug in the USB drive to see mount point.

# scan for all drives
df -Th
Filesystem     Type     Size  Used Avail Use% Mounted on
/dev/sdc1      fuseblk   30G   66M   30G   1% /media/ulysses/451B99AF225B48EC

Unmount USB drive.

umount /dev/sdc1

Choose a file system type and run the appropriate format command.

# nfts format
mkfs.ntfs /dev/sdc1
# vfat format
mkfs.vfat /dev/sdc1
# ext4 format
mkfs.ext4 /dev/sdc1

Display Sequential Write Throughput

Here’s a dd command to display sequential write throughput from the command line.

time dd if=/dev/zero of=/mounted_backup_volume/zero.raw bs=1M count=512 status=progress

Output is.

Audacity on Catalina

If you’ve recently upgraded your Mac to Catalina or Mac OS 10.15.1, you may have noticed that Audacity is no longer working. To get it working, you’ll need to download version Audacity 2.3.3. However, installing and running it normally the way you’ve done it in the past will not be enough. Because of Catalina, Audacity is not able to gain permissions to the microphone inputs. The only way I was able to get it working is to launch Audacity from the Terminal.

Launch Audacity from the Terminal.

# cd to Application directory
cd /Applications/Audacity.app/Contents/MacOS
# Run it in the background
bash Audacity.sh &

Click Ok if prompted to use the microphone.
