It is perhaps /proc or something else. So how can I for sure know which harddrive I am using Debian?
Command to see the size of Harddrive in Debian?
debian
I think fdisk or df should do for you.$ sudo fdisk -lDisk /dev/sda: 128.0 GB, 128035676160 bytes255 heads, 63 sectors/track, 15566 cylinders, total 250069680 sectorsUnits = sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x76e7062aDevice Boot      Start         End      Blocks   Id  System/dev/sda1            2048    70383615    35190784    7  HPFS/NTFS/exFAT/dev/sda2   *   249434112   250048511      307200    7  HPFS/NTFS/exFAT/dev/sda3        70385662   249432063    89523201    5  Extended/dev/sda5        70385664    71383039      498688   83  Linux/dev/sda6        71385088    73383935      999424   82  Linux swap / Solaris/dev/sda7        73385984   249432063    88023040   83  Linux$ df -h #working on DebianFilesystem      Size  Used Avail Use% Mounted on/dev/sda7        84G   75G  5.6G  94% /udev            1.9G  4.0K  1.9G   1% /devtmpfs           768M  944K  767M   1% /runnone            5.0M     0  5.0M   0% /run/locknone            1.9G  364K  1.9G   1% /run/shm/dev/sda5       484M   47M  413M  11% /boot
