I am logged in as root at the command line prompt. I have this new 4TB Western Digital My Book Studio USB2.0/3.0 external hard drive which I intend to use as backup storage. I tried plugging it in but this is what I get:
[325053.885636] sd 10:0:0:0: [sdg] No Caching mode page present [325053.887454] sd 10:0:0:0: [sdg] Assuming drive cache: write through [325053.894273] sd 10:0:0:0: [sdg] No Caching mode page present [325053.896423] sd 10:0:0:0: [sdg] Assuming drive cache: write through [325053.953886] sd 10:0:0:0: [sdg] No Caching mode page present [325053.955547] sd 10:0:0:0: [sdg] Assuming drive cache: write through _
It remained stuck there for more than 15 min. So I pressed CTRL+C to abort. sdg shows up fine in lsblk with two partitions sdg1 (200M) and sdg2 (1.7T) and does not appear to be mounted, and the USB device appears in lsusb, so it's connected and the system knows it. fdisk -l gives me this:
Disk /dev/sdg: 4000.8 GB, 4000752599040 bytes 255 heads, 63 sectors/track, 486397 cylinders, total 7813969920 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdg1 1 4294967288 2147483644 ee GPT Partition 1 does not start on physical sector boundary.
I have two questions:
(1) Is it OK for me to proceed with ext3 formatting and manual mounting?
(2) Why did the system hang after I connected the external drive and what is the problem with the physical sector boundary?
Just wanting to make sure I'm not missing out on anything important, and taking the opportunity to learn.
