Is there a command line tool to shut off/spin down the hard disk either when not in use or when something is typed into the console? I'm trying to save power in a laptop I have..
View 2 RepliesI'm not sure how to do this. I checked the hard drive preferences and looked through the forums... I don't want to manually mount my hard drives(s) every time I boot up just to access my music and wallpapers.

It is a physical old HP machine (netserver lc2000) with a fresh debian wheezy 7.0.8 installed.
It has two scsi hdds (73GBs) that I don't know how to add to the system so I can partition, format, mount, etc.
This is what I have tried so far:
1. dmesg output
Code: Select all# dmesg | grep scsi

Code: Select allecho "- - -" > /sys/class/scsi_host/host3/scan
-no errors, but log says nothing
-tried the above with host0 - 4, same result
4. fdisk -l

I have installed a minimal system with openbox window decorator. (without any window manager) when i insert a flash disk to my computer, system doesn't mount it automaticly. i must mount it to a folder to use it.
for example:
I am running Debian 3.2.0-0.bpo.2-amd64 on hyper-v, my / volume ran out of space and is sitting at 100%, I have extended the disk size on hyper-v, however when I go to Fdisk I see duplicates of each disk.
I have total of 2 vhds on the vm, so I see 4 disks under fdisk. Here is the output of fdisk
root@apachevm:~# fdisk -l
Disk /dev/sda: 107.4 GB, 107374182400 bytes

I'm trying to do some RAID managing with mdadm. I would like to sync my spare disk and then remove it from the array for making a backup out of it with dd command (the best way i can think of to get the current image of the whole system as it can't be done using the active RAID as source, because is constantly in use and changing). So, I have RAID1 array with 1 spare and 2 active disks (configuration listed below). Now I would like to force spare to sync and then remove it from array, although not faulty.
However, mdadm man page states:
"Devices can only be removed from an array if they are not in active use. i.e. that must be spares or failed devices. To remove an active device, it must be marked as faulty first."
So, I'd have to mark a disk as faulty (which it is not) to be able to remove it from array. There seems to be several people reporting that they can't remove this faulty flag accidentally given to a drive. And mdadm does not give direct for such operation. Isn't there a way I could remove and add disks whenever feeling like it?? One way would be open the cover and physically remove the disk. I'm not taking the risk, though. System is almost always in use, so there is not much chance for me to power off for temporary disk removal.
RAID CONFIGURATION:
~# mdadm --detail /dev/md0
/dev/md0:
Version : 00.90.03
Creation Time : Fri Aug 4 17:38:26 2006
Raid Level : raid1

I have never seen this one before (see below) - note how /dev/sda1 is mounted from the first disk listed by fdisk, but /dev/sda2 comes from the second disk; what is going on here? This is what I did: I installed the latest debian "Testing", which went well - it found the disks in the order show by fdisk -l here. When it booted up after installation, it failed because it couldn't find /, which I repaired by editing the grub menu (I told it to start from the other disk), and it came up. But now I had to mount /u01 by hand from /dev/sda1; strange. I suppose I could just go and change the physical disks around, but I'd like to understand this. Any ideas?
# fdisk -l

I have installed Debian Squeeze on my Laptop. Everything seems to start to work fine. The only think I am not sure is the hard disk click sound only when I shut down the computer. It happens right before the power is totally cutoff. I normally do not have this sound. I presume that this maybe due to the fact that the head goes back to original position but I am not sure. Is this normal?

However when the app tries to connect it always gets connection refused at gatt_connect.
gatttool behaves the same way, and hcidump does not show any connection attempts, implying no connection between gatttool and the device, although it is specified on the command line.
Finally although the bluetoothd is running bluetoothctl also shows no default controller found. I had edited /etc/bluetooth/uart.conf, adding an hciattach entry for the device but that changed nothing when restarting the bluetoothd. Entering a garbage entry into that file does not produce any errors, so I am not sure it is even being read.
Also systemctl|grep bluetooth shows :-
sys-devices-virtual-bluetooth-hci0-rfkill0.device loaded active plugged /sys/devices/virtual/bluetooth/hci0/rfkill0
sys-devices-virtual-bluetooth-hci0.device loaded active plugged /sys/devices/virtual/bluetooth/hci0
sys-subsystem-bluetooth-devices-hci0.device loaded active plugged /sys/subsystem/bluetooth/devices/hci0
bluetooth.target loaded active active Bluetooth
/sys/devices/virtual/bluetooth/hci0/address shows the correct MAC, but /sys/subsystem/bluetooth/devices/hci0 does not exist, a post elsewhere indicated this was not a problem but that seems odd.
Is the uart.conf file still used([URL] .... would suggest yes) and if so is the format a full hciattach command or merely the hciattach parameters?
I decided to update all the software on my computer. Fortunately, it upgraded kernel version 3.14 to 3.16. I was happy to learn that suspend now worked on my laptop by calling pm-suspend, but it did not worked by closing the lid. So I search and found on debian's website that installing systemd and adding some config lines in /etc/systemd/logind.conf would sove the issue. So I followed the procedure and did like instructed, to end up with a computer that boots on black screen.
The last verbrose line I see on boot up is "kvm disabled by bios" and then it shutdown down the screen. The computer works, as I can login and shutdown by doing those operation blindly.
I tried removing systemd but it still does not work. If I use the old kernel 3.14 I can boot without any problem, but if I use kernel 3.16, I boot to a black screen. I remember successfully booting in 3.16 before installing systemd.
Fstab has at the end some values: 0 1 for / or 0 2 for /home or others.

I've bought a new notebook. The hard drive won't stop spinning down and then spinning up again during load. I don't want HD power saving, so I disabled it within
1. /etc/hdparm.conf
Code: Select all# -B apm setting
apm = 255
# -B apm setting when on battery
apm_battery = 255
It didn't work. I can still hear the HD spin up. It's annoying in a video game because things just suddenly stop for a second.
2. /etc/udev/rules.d/50-hdparm.rules

View 3 Replies View RelatedI'm using SUSE11.1, and connected to my system, a DELL 7500, a 1.5 TB Buffalo external HD. I partitioned it in 4 sectors.After connection, nmediatly the mounted disk would appear on the screen,(each partition with its respective name), and could use it as any other folder.To unmount the external Hard disk, I just ejected each partition, and had no problem. I used the same HD with my Mc, and things were all right, I used to backup automatically the Mc. However after having been using the system in this way for more than half a year, suddenly the hard disk began to rattle...and the SUSE system on the DELL, nor the Mc can mount the external hard disk any more. Thus, the partitions can not be mounted any more. When I cd to /media/ in the SUSE, the names of the partitions appear, but they seem to be empty..On the Mc, going to /Volumes/, before the problem appeared, the names of the partitions were there... but now, they are no more and the automatic back up either.So my question is, how to mount the disk, if it needs mounting... or how I can recover the partitions and the data therein... I am clueless, after two weeks trying to solve the problem..

So the hardware is basically working.What I want to do is configure lilo so I can choose to boot either 13.0 or 13.1. So far I have not gotten this to work.
Under 13.0 the slave disk appears as /dev/hdb. The root-partion for 13.1 on the slave is the first primary partion on the slave, and appears as /dev/hdb1 when viewed under 13.0. What stanza should I add to lilo.conf to make the slave 13.1 bootable?

View 3 Replies View RelatedI thought that alignment of 4096-byte sector Advanced Format hard drives was automatically taken care of via Gparted or Disk Utility until I bought a Hitachi HTS547575A9E384 (Travelstar 5K750) and saw that Disk Utility showed my partitions to be out of alignment. I then realized that my WD, which I had bought a few months ago, probably had its jumper set to emulate a 512-byte sector legacy drive (512e) and is probably not set to the AF setting.
Straight to the problem.
I've searched many sites, some of which suggest using fdisk (others the proprietary software of the hard drive's manufacturer). It is essential that one change the arguments prior to changing the partition table as there is no way back (yet, as far as I know) without having to move data to another drive and starting all over:
