Hardware :: Debian Lenny And Support For WD 4K Sector Hard Drives
Jan 15, 2010
As you are probably aware that WD released new drives ranging from 1TB to 2TB with native support for 4K sector size. And as most of stuff written online is regarding Windows and their support for 4K, my question is has anyone already started to use it under linux?

I'm thinking about getting one of these drives:
1TB WD10EARS
or
1.5TB WD15EARS
I'm using Debian Lenny so my questions are: is fdisk automatically recognizes that that drive is 4K drive, or it totally ignores it and partition is as 512byte one? In windows if no 4K support is available it would emulate it and performance would be downgraded. Do I need to enable any specific components in kernel so 4K drive is supported? I wanted to make sure there would be no data loss if I select 4K partition type.

It all started about a week after upgrading to Jessie and I had an unusual system failure, in that the CPU went to 100% usage and the hard drive light was on constantly. The keyboard and mouse were were non-responsive. Not having REISUB enabled I did the "stupid" thing and pushed the reset button on the computer. BAD BOY! As a result the computer would not boot and I had to use a live CD to format the drive and install Wheezy (I had the CD).
After installing Wheezy, everything worked well for about 3 days and then it did the same thing. Fortunately I had REISUB enabled and was able to reboot. I looked at the syslog and found a segfault with colord-sane and, after some research that suggested colord-sane might be a problem, I set UseSane=1 in colord.conf . Things seemed to be okay for about 4 days.
Well, after all that I had another problem today with booting. During boot I got an error message saying that there was some hard drive problem and that I needed to log in and run fsck, which I did . There were I believe 4 INODE errors that I was asked if I wanted to repair, to which I responded yes. After that the system booted correctly. After booting and entering the Gnome Classic desktop I looked at the Disk Utility and checked the SMART data. There is now 1 bad sector where before there were none. The drive is a one year old WD 500GB Velociraptor.
Don't know if this is relevant, but in the days before this latest "crash" I had downloaded about 8 movies using bittorrent. Could this have overtaxed the HDD?
I guess my questions are: When fsck "repaired" the disk would it have moved any data from the bad sector to a new location? What may have caused the sector to go bad ? Should I be buying a new hard drive?
The system seems to boot okay,at this time, so I assume that no critical system files were affected. Just curious as to how I should proceed. First is BACK UP my data. Got that !
One more thing I just thought of is that every time it "crashed", I was using LXDE.

Software RAID 5 on 4 2TB caviar green disks. Then 12 partitions or about 500GB, and finally LVM to use the partitions as pv, and create some vg for my needs.
My disks are /dev/sda to /dev/sdd I boot on /dev/sde which is an sd card
My doing (and at the end, my issue):
Code:
(parted) select /dev/sda
(parted) mklabel
Warning: The existing .... blablabla [msdos] ? gpt
(parted) select /dev/sdb

where do i find out the latest news and tech info about support in debian for nvidia cards on the ppc64 platform? i have lenny installed on a g5 single 1.8 ppc64 mac and am experiencing problems viewing output from videos that i believe are related to video support or rather lack there of.

Primary symptom: /proc/self/fd is there and normally populated, however /dev/fd is not. Process substitution therefore fails, because bash wants to create files under /dev/fd./dev/.static/ and /dev/.udev are populated. aptitude udev shows that the Debian package is installed, even though udev cannot be supported on this Xen vps (and, I believe, isn't supported by default until later stable versions of the Linux kernel).
I can solve the immediate problem by symlinking from proc/self/fd to /dev/fd, and putting the appropriate script in init.d. But are there any risks arising from Debian being misinformed about what my vps can do? And if so, what should I do about it?

Last month I found an old Seagate Hornet tape drive (STT20000A) with 2 TR-5 tapes at a thrift store. After sitting on a shelf at my place until last week I put it in an old system and installed Debian 5 on it. After a long time of working on it and never finding any useful help newer than 2007 I'm about to put it on eBay. So, here's a few questions:
Can this work in Debian 5 or should I put 4 or older on the system? If I put older linux on it, could I still get ide-scsi module working? apparently it has be obsolete for some time. The main problem is that it locks up the system when I try to write to it.

i just burnt a debian lenny 504 live disk. i don't think there's a way to install it to hard drive. i just did a google search and it appears that the latest debian lenny 504 cannot be installed to hard drive with the live cd. from what i have read, i need to get a "netinstall" iso (this is new territory for me). can anyone supply me with a link for an iso with a hash verification? i would be most grateful. the disk i had previously must be corrupted because the install quits at 5%.

I've recently brought a Western Digital Elements 2TB external hard disk and have been planning to encrypt it for use as a backup drive. However, it seems that these 2TB disks use the new 4K sector sizes and thus need to be handled more carefully than the older 512K ones.
After spending a week looking on Google, I have to admit I'm pretty confused and hope somebody here might be able to verify my conclusions
The drive reports that it's a 512-sector drive which is probably false. Using fdisk -uc, the original partition starts at sector 2048 so I assume that is a valid sector also to start a dm-crypt partition overwriting the previous one?
I've also read that every layer that is added to these drives must support the 4k layer. That means both dm-crypt and the ext3 filesystem I intend to put it on have to do so also.
Looking through the cryptsetup document, it states under the option "--align-payload" the following:
"Align payload at a boundary of value 512-byte sectors. This option is relevant for luksFormat. If your block device lives on a RAID, it is useful to align the filesystem at full stripe boundaries so it can take advantage of the RAIDs geometry. See for instance the sunit and swidth options in the mkfs.xfs manual page. By default, the payload is aligned at an 8 sector (4096 byte) boundary."
The fact that the payload is aligned at 4096 seems to indicate to me that it should be fine using default settings. Does everybody agree with this? Or do I need to take special measures due to the dm-crypt headers?
When I later finish up the dm-crypt layer, then I need to put ext3 on it. I understand adding -b 4096 to the mkfs.ext3 command will resolve that. Is that also correct and will it work well in combination with the dm-crypt layer?

I'm going to replace damaged HDDs in my server with new drives, which have sector size of 4096 bytes instead of 512. Does CentOS natively support such drives? If yes, since which version? If no, what actions should I take to correctly prepare such a drive to work. How to check that such a drive is correctly recognized by OS?

I'm trying to install jessie on a new computer, but the installer does not see the hard drives. I copied the DVD-1 iso to a usb stick with dd (also tried the netinstall) and it boots, but when I get to partitioning, it only sees the usb drive. If I go to another virtual console and run dmesg or fdisk -l, all drives are seen correctly.
Back up a little - at first I tried the on-board raid, but when the installer couldn't see the drives, I went back into the bios and reset the sata mode to ahci. I've got it set to use bios/legacy OS, or whatever it's called, fast boot is disabled. Even if only one drive is connected, the debian installer does not see it. Then I read up on the fake raid I was trying to use and decided to go with software raid. Can't do that if there's no hard drives listed in the partitioner.
My own installer (refractainstaller) does work, and I've installed jessie with it a couple of times onto one drive, but I really wanted to use raid and lvm, and my installer doesn't do either of those things. No optical drive, but if that's the only way to install, I'll pull the one from my current box and use it for the install. I think I still have a blank CD or DVD lying around.
Hardware:
ASUS H97-PLUS LGA 1150
Intel core i3 (the cheapest one at newegg)
WD Black 1TB drives (2)
GSkill cheap memory, which already passed a memtest.

I am trying to switch over my NAS from Win7 x64 to Debian 8.x Jessie. I have run into a few issues with the power management. When Idle my NAS should be consuming 25W, however it was consuming much more. The more hard disks I mounted, the higher the wattage.
I have followed a few tutorials but that has only been a partial succes.
Code: Select all # hdparm -C /dev/sd[b-y]
/dev/sdb:
drive state is: active/idle
/dev/sdc:
drive state is: active/idle
/dev/sdd:
drive state is: standby
/dev/sde:
drive state is: active/idle
/dev/sdf:
drive state is: standby
All the drives can spindown but they are not doing that now that they are mounted.
hdparm:
Code: Select all/dev/disk/by-id/ata-SAMSUNG_HD103UJ_S13PJ9AQC12015 {
apm = 127
keep_features_over_reset = on
spindown_time = 60
[Code]....
Now there are two suggestions I found but both I was unable to implement.
The first suggestion was to mount using "noatime". However I do not know how to rewrite fstab because I am using ntfs for now (at least untill I get it working).
Code: Select all# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
#
/dev/mapper/bugattidebian--vg-root / ext4 errors=remount-ro 0 1
[Code] .....
Not sure where to add the noatime there...
Also I am using samba on all those drives. This guide suggested a code change but the example does not line up with my configuration script.

How to mount multiple external HDD's. I'd like to link or mount the music, torrents, and general files from several external hard drives and apply permissions (in some cases I only want the mount or link to be read only).
My setup:
- Seagate Dockstar running Debian squeeze (it's headless so I don't have a gui running)
- Two external HDD's with one partition on each (250GB and 400GB)
What I'd like to accomplish:
1. Mount the external HDD's to /media/HDDs as read/write (this is already working using udev and autofs and it's available in samba)
2. I'd like the MUSIC directories on both external HDD's to show up under the same mount point. In other words I want the MUSIC folders (from both HDD's) to appear as one large library of music. And I only want this to be readonly. It will be used as the library for mpd and/or squeezebox.
3. Mount a directory used to download torrents to. I'll probably pick on HDD as the target for torrent dowloads. But let me know if you have any other ideas regarding this.
Since I have the first one done, how would I accomplish 2 & 3?

I have two servers (A and B) which are identical. My idea was to have a software RAID 1 with both of them running and if server A craps out I wanted to swap the hard drives from server B into server A. When I tried to test this idea the network driver doesn't seem to want to cooperate. ifconfig gives nothing and I can't figure out why. From googling I've read that a network card has a unique ID on it (I'm assuming their talking about the MAC address) and is used in some config files which is why swapping hard drives gives two different MAC addresses and confuses the system. If that is so would anyone know exactly what config files the mac address is stored/used in? That way I can make a backup of those files and swap those out if I ever need to swap out the hard drives.

I have searched for this but can not find it. I want to install debian 6.0 squeeze on to both of my hard drives and run each as a seperate instance of debian, and be able to choose at boot up which one I want to run. I have an HP with 2 500 gig hard drives, running windows vista currently, processor is an intell quad 2 core 6600, nothing else on the pc for programs and such at this time. I would also like to keep the windows if possible to run other programs at a later time.

I am currently thinking about moving my debian install onto another more powerful motherboard/processor/ram amount. My question is how difficult will the move be?
I have done some reading on cloning and or moving. It seems like moving is the best bet,
[URL]
It looks like its as simple as moving the harddrive. But what about multiple hardrives with LVM set up? I also realize I will probably have to find the network drivers for the new motherboard. There's probably other drivers that will need to be installed as well. What would need to be configured in terms of VM set up?
The former set up is,
Asus MB with i3 and 8GB of ram 3 hard drives
VLM set up
samba server for the local windows machines
Virtual Box with one VM - Win 7
SNTP server set up to serve the home network.
SSH with keys
VirtualBox PHP
Transmission for torrents
Plex and Subsonic (for remote streaming), other assorted packages
New Set up is,
Intel mobo with i5 and 16 GB of ram
-I would literally be moving the hard drives into this computer

I choose the drive to boot to from the computer Bios. When i boot into Windows my clock time changes, about 5 hours.I have another computer with Ubuntu 10.10 installed, but it will not install on this computer, Debian Did. Ubuntu gave me a command to fix this and it worked. However the Debian computer will not accept that command, Which is open a terminal from the menu applications accessories and type gksudo gedit /ect/defaults/rcs in this configuration change the row UTC set it as:UTC=no save and reboot and then set the clock. [It was set to yes]

I am building a home server that will host a multitude of files; from mp3s to ebooks to FEA software and files. I don't know if RAID is the right thing for me. This server will have all the files that I have accumulated over the years and if the drive fails than I will be S.O.L. I have seen discussions where someone has RAID 1 setup but they don't have their drives internally (to the case), they bought 2 separate external hard drives with eSata to minimize an electrical failure to the drives. (I guess this is a good idea)I have also read about having one drive then using a second to rsync data every week. I planned on purchasing 2 enterprise hard drives of 500 MB to 1 GB but I don't have any experience with how I should handle my data

I just upgraded to Fedora 11. (I decided to give 64bit a try and I am extremely impressed.Not one problem at all! Kudos to the devs.) Whenever I log in I get the Palimpsest Disk Utility telling me two of my hard drives have a reallocated sector count.I have two 1.5Tb Seagate drives (model #: ST31500341AS). One is a backup of the other. On the first disk the disk utility tells me I have 22 reallocated sectors and 53 on the second. I've been on Google on discovered that there is no easy way to fix this and that a few bad sectors are okay but too many is a sign of imminent drive failure. This obviously concerns me because both my main drive and its backup are showing errors.
I went to Seagate's website and downloaded their diagnostic software (Seatools for DOS) and it passed both of these drives.So, questions: is it possible that Fedora is giving me a false positive? If not, is 22 and 53 sectors something to be concerned about? If so, should I contact Seagate and see if I can pull warranty on these drives? Is there a way to repair this damage?

I have Fedora 14 installed on my main internal drive. I have one Fedora 14 and one Fedora 15 installed on two separate USB drives.When I boot into any of these drives, I can't access any of the other hard drives from the other drivesll I can, but just the boot partitions.Is there any way of mounting the other partitions so I can access the information?---------- Post added at 12:42 PM ---------- Previous post was at 09:34 AM ----------I guess even an explanation on why I can't view them would be good too.

Some posts say 11.3 and newer automatically detect drives that have 4kb sectors, and partition things accordingly. But other recent posts specifically about 11.4 say, no, you still have to prepare the drive manually before installing, to be sure things are optimized.

I have a SATA drive that worked fine. Then I installed two more hard drives into my system. When these hard drives are installed, if I try to access the SATA drive in Linux, it will start lightly clicking and then the drive will become unavailable. If I power on the machine without the other two hard drives then it works fine. What could be causing this to happen? I don't think it's heat because the two hard drives are far away from the SATA drive.

i was trying to use gnome and kde but i don't like them. I tried xfce and it seem to fit my needs but.My computer is used to be powered on for a weeks. While time passes, a process xfdesktop begin to use more and more memory and to free RAM i need to log out and log in again.
I tried squeeze yesterday on my virtual machine and it has 4.6 and seem not to have that bug, RAM usage is static(yes it still works when i write this and have memory usage 34492k, which is not changing for an hours of usage already), also 4.6 is MUCH better than 4.4.
i already tried adding squeeze to "sources.list" but i can see too many dependencies which should be upgraded if i install 4.6, i'm beginning to afraid it can crash entire GUI(or entire system, i can see there is libc6 required to be updated).

I have a PC104 running debian. I have 3 hard drives (in addition to the one booting) mounted in fstab by UUID. I use the options defaults,error=remount-ro. However, this means that when I boot with the hard drives not attached, I have to press Ctrl-D to bypass when the boot discovers the drives are missing. Is there a timeout commandoption I can add to fstab so that it automatically continues booting even if the hard drives are not attached? I could not find anything on a timeout command. (I tried adding timeout=1000 but no-random guess)

I want to use an eSata enclosure which will combine 2 drives into one so I'd be presented with 4TB.
Can 32-bit 9.04 cope with this as one partition or would I have to create multiple partitions on it?

Upon installing Fedora on my Samsung NC10, I loved it. It feels stable and isn't cluttered with pointless apps. However I was immediately greeted by Palimsest Disk Utility warning me that the 'reallocated sector count' on my hard drive is going bad. I'm not too sure what any of it means but here's the statistics;
ID: 5
Attribute: Reallocated Sector Count
Current: 100
Worst: 100
Threshold: 10
Value: 1 sector
Status: failing
type: pre-fail
status: updates
It also says the temperature is 46 degrees yet the netbook's taken to being very, very hot around the touchpad and under the hard drive.

I am trying to install Ubuntu to an external usb hard drive (WD Elements SE). I am also choosing to install the grub bootloader to this disk (/dev/sdb) because I do not want anything modified on the internal drive. The installation appears to go okay, but when I try to boot to the usb drive, I get the error, "no boot sector on usb device" and it immediately falls back to my interal drive. I have tried this installation with both 10.10 (amd64) and 11.04 (amd64). How can I fix this?

Have Opensuse disabled support for Iomega external parport zip drives? I can mount the zip drive under Debian Lenny running the 2.6.26 kernel without any problems. Under Opensuse 10.3 (installed) and Opensuse 11.2 (liveCD) I can't access the drive. Opensuse doesn't recognize it.
All of which is odd. When I installed 10.3, the zip was seen an configured in fstab as /dev/sdc4 mounted at /media/zip. It worked fine for a while, then quit. Now, /dev/sdc4 doesn't exist. Kde control center says (hardware - partitions) says is there but not mounted. Hwinfo doesn't show it; modprobe imm does nothing.
I'm at a loss for ways and means to get Opensuse to recognize my zip drive.
