To use these partitions, you first need to format the newly created partitions to be used to create the file system
Use command mkfs-t Ext3/dev/sda3Mkfs-t EXT3/DEV/SDA4Mkfs-t Ext3/dev/sda5

Linux shadows can be seen on smartphones, handheld computers, portable devices, Apple computers, and mainframe/giant computers. iPod has the computer elements-storage devices, central processors, can she install Linux? The answer is yes.
So why install Linux on the iPod? -- DIY spirit! Do it yourself! Isn't it true that if you like DIY, you don't want to try a distinctive personality?

Add a new 5G hard drive to VMwareShow current partition# fdisk-lUsually when you add a new hard disk to a virtual machine, you may see that the new drive is not loaded automatically. This is because the SCSI bus connected to the hard drive needs to be re-scanned to make the new hard drive visible.Here is a simple command to rescan the SCSI bus and SCSI devices.Determine the host bus number# LS /sys/class/scsi_host/ Host0 host11 host14 host1

see@ Card farmer Solo : 5G technology is successful, according to the Daily Mail of the UK, scientists at the University of Surrey in the UK have recently developed the latest and fastest 5G network technology. It can transmit about 125GB of data per second, 65,000 times times faster than current 4G technology. At this speed, the current 30 movies can be downloaded per second. (CCTV net)With the 4g,
