下午跑去 NOVA 買了顆 2.5 吋 WD800UE 小硬碟,它的外觀如下:
據說 WD Scorpio?技術還不錯,夠安靜。
當然,回到家就馬上接上 X31,底下是 Linux 偵測到的硬體資訊:
USB Mass Storage support registered.
usb-storage: device found at 2
usb-storage: waiting for device to settle before scanning
Vendor: WDC WD80 Model: 0UE-00HCT0 Rev: 09.0
Type: Direct-Access ANSI SCSI revision: 00
usb-storage: device scan complete
SCSI device sda: 156301488 512-byte hdwr sectors (80026 MB)
sda: assuming drive cache: write through
接著用 fdisk /dev/sda 作切割:
Command (m for help): p
Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 1 9729 78148161 83 Linux
再用 mkfs.ext3 -c -j /dev/sda 作檢查並格式化,最後用 tune2fs -m 0 將保留空間釋放。
# mount /dev/sda1 /mnt/tmp/
# df -h /dev/sda1
Filesystem 容量 已用 可用 已用% 掛載點
/dev/sda1 74G 33M 74G 1% /mnt/tmp
來測測看速度吧!X31 裡硬碟的速度:
# hhdparm -t /dev/hda
/dev/hda:
Timing buffered disk reads: 74 MB in 3.00 seconds = 24.66 MB/sec
而新入手的 WD 小硬碟呢
# dparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 60 MB in 3.05 seconds = 19.64 MB/sec
嗯,慢了一點,不過還是適合我用來備份資料 :)
