Got an ATA hard drive hooked to an external USB package and need to reformat the disk to ext3 system.<\/p>\n
First, I run fdisk to see what content it has
\nfdisk -l \/dev\/sda1<\/p>\n
Then, I re-partition it using
\nfdisk \/dev\/sda1
\nselect option d to delete the old partion,
\nand then option n to add a new partition, where I choose the primary partition instead of the extended one. There will be complaint about it’s too large, but since this disk is not going to be used as a boot disk, so I don’t care<\/p>\n
Next, I create the ext3 file system on the partition
\n\/sbin\/mkfs -t ext3 \/dev\/sda1<\/p>\n
After it’s done, I can mount it to my Linux system
\nmount \/dev\/sda1 \/disk3<\/p>\n
Optionally, I can change the percentage of reserved blocks using tune2fs, e.g., from the default 5% to 3%
\ntune2fs -m3 \/dev\/sda<\/p>\n","protected":false},"excerpt":{"rendered":"
