Ubuntu :: SATA II / Error "ata4: Limiting SATA Link Speed To 1.5 Gbps" - Allowing The SSD To Run At SATA II Speeds?

May 1, 2011

I keep getting this error in my log viewer every 2 seconds: Code: ata4: limiting SATA link speed to 1.5 Gbps I have a dual boot SSD and I have run many SMART tests in windows and linux, (using smartmon tools and the disk utility) and the reports are all 100% healthy..... My research shows that this error represents one of the following:

1. Problem with SATA controller
2. Changing BIOS to allow SATA
3. Changing SATA mode to PATA or AHCI
4. Replacing the SATA cable
5. Allowing the SSD to run at SATA II speeds, i.e. 3 Gbps

- Does anyone know how to try number 5, i.e. allowing the SSD to run at SATA II speeds? I am lost here and this problem has caused my machine to crash twice when watching a movie in linux/ ubuntu. (It is worth noting that the crashes have only occurred in linux and I have never had an issue in windows, so it does seem to be a linux setting somewhere, hence why I think it is a "allowing SATA II to run at correct speeds issue")

Ubuntu :: SATA Libata Verses Silicom Images SATA Module

Jun 21, 2010

I installed Ubuntu 10.04, and happened to have an Silicom Images PCXpress card plugged in, and it kindly added the sil_sata module.This is fine for this chip set.I think that my earlier installation of Ubuntu 9.04 used Libata, which does support NCQ and also has good legacy support for the Intel Intel ICH7 chipset I have inside my Sony Vaio SZ notebook. Also, libata also support Silicon Image chipsets as far as I can tell from URL...I wish to remove the Silicom Images SATA modules and replace this with libata and then test the performance between the two device drivers.

Ubuntu :: External SATA Transfer Speeds?

Mar 26, 2010

I just bought a 1Tb hdd and reformatted to FAT32 it is connected via eSATA to SATA cable.At first I transfered music that initially was getting speeds over 100mb/s (according to nautilus) after about a minute it started to dwindle. Now most files will range somewhere between 8-20mb/s although I've only seen a couple go beyond.i edited hdparm.conf to enable DMAHere is the output of hdparm -Tt for both internal(sda) and external(sdb) hardrives.

Timing cached reads: 14872 MB in 2.00 seconds = 7444.68 MB/sec
Timing buffered disk reads: 372 MB in 3.00 seconds = 123.91 MB/sec[code]....

What is the issue this output leads me to believe that I should be getting the same speed I once got.I'm running Intel Core 2 duo at 3.00, ASUS P5Q (enabled AHCI) and 4gb ram 12gb linux swap. Also Karmic 9.10

Hardware :: PATA Socket Was Replaced With SATA Socket / Transfer Rate Of The Harddisk Would Be SATA Transfer Rate?

Jul 4, 2010

My friend bought an old hard drive. He noticed something with the hard drive that it was just replaced with a SATA socket. So meaning, the SATA socket was soldered to the PATA hard disk to replace the PATA socket to SATA socket to make it a SATA.

Now the question is:

1. Does the Transfer Rate of the harddisk (that has been replaced from PATA socket to SATA socket) would be SATA transfer rate? OR would still be PATA transfer rate?

OpenSUSE Hardware :: Random Error - Could Not See SATA Drive ?

May 6, 2011

I experienced a strange random error that appears to have been my PC losing contact with the PC's 1.5 TB SATA drive.

This happened once (thus far only once - about two hours ago) on my Intel Core i7 920 PC with a Asus P6T Deluxe V2 mother board running openSUSE-11.4 with KDE-4.4.4. A reboot failed to fix the problem but a cold shut down restart did.

Some details ...

I had a zillion apps open, connected to my mother's PC in North America (from here in Europe) using vnc, had thunderbird, firefox, many konsole sessions, and various leafpad editor sessions.

Firefox appeared to hang, so I tried to close the Firefox page, but the PC appeared frozen (although the mouse would move). Then after about 60 seconds, the screen flashed, firefox closed (crashed may be more accurate) and I had my desktop back, ... sort of .... And I was able to go to the desktop area where vnc was running and access my mother's PC. But I was missing almost all the icons off my KDE destkop and most the icons off the panel at the bottom of the desktop.

I tried going to <CTRL><ALT><F1> and then <CTRL><ALT><F7> but that made no difference. I tried going to <CTRL><ALT><F1> to login but it would not let me login as a regular user, nor as root. Nor could I ssh into the PC. After <CTRL><ALT><F7> back at the crippled GUI, I typed 'shutdown -r now' (as root) but the command was not recognized. Neither was 'top' (as a regular user), nor 'fdisk' (as root). Dir was recognized as a regular user as was CD. But I did not believe the information those commands were giving me (it did not appear up to date).

Eventually I killed X with <CTRL><ALT><Backspace> (twice) and then forced a shutdown start with <CTRL><ALT><DELETE>, but then the PC hung during the shutdown, with the hard drive light on solid. That never happens. After a minute of that I decided to hit the 'hardware' reset. The PC restarted, but was incredibly slow to go through the motherboard boot menu's and it reported the hard drive not detected and would not boot. I did a <CTRL><ALT><DELETE> to restart, and pressed DEL to go to BIOS, and then noted in BIOS that the SATA drive was not detected.

I checked the temperature and the PC was a nominal cool temperature (38 to 40 deg c).

I then switched OFF the PC. I also turned the OFF switch on the back OFF for good measure. I waited a minute. And I turned ON again the PC.

The PC booted normally as if nothing had happened.

Most bizarre and a bit of a fright. My Linux is usually rock solid.

Anyway, ... no more investigation for now. I'm doing a massive backup of all data since my last backup. This will take a while as I have about 400 GB of home movies (at various stages of processing) from my home video camera to backup to an external hard drive.

I may pickup another 2TB external drive this weekend, just to ensure I have multiple backups.

Hardware :: SATA Error -> Sys Hard Reboot On Suse 11.3. Board + Hdd Changed - Error

Feb 1, 2011

i actually registered here because i'm done with my knowledge of linux, errors which cause my sys to hang and/or reboot randomly after some time. They occur while the system is under heavy cpu, heavy mem-read-write, mediocre mem fill, heavy hdd io (for ~20 seconds every ~5 minutes).

problem background we ordered two identical PCs (specs below), one of them brought those sata errors quoted below from /var/log/messages, the other one runs flawlessly. Same Hardware and Software Configuration. Faulty one brought reallocated sectors right at start, mass seek errors, read errors. 1st try: swap cables, change bios mode ata_piix <-> AHCI. Didn't work. Went away for repair. Stupid Techie did only swap hdd, so problems occured again. Shipping for repair again. Board AND hdd exchanged. no more seek/read errors, no more reallocated sectors. But similar sata problems right after 3 days of previously described workload. Following logs are from after the last repair.

Debian :: SATA Raid, /home Partition Mounting Error?

Nov 9, 2010

I've installed debian squeezy recently and for some reason I have problems with mounting /home partition during startup.

There's an error:Mounting local filesystems...mount: special device /dev/mapper/isw_bbfedcffgi_Volume0p6 does not exist. failed

I've tried using fsck - no result the file system is healthy, I've tried formatting it once again (fresh copy, no user data) and it's not working. What is more mounting the partition manually goes well - I can read the data and write to it. All other partitions are ok.

I have no idea what's going on and why mounting /home fails. I've written this post on Polish debian users forum, but no response - only to give more info, so I'll put it here also:

ls -al /dev/mapper

crw------- 1 root root 10, 59 Nov 9 19:34 control

Server :: GRUB Read Error After Adding SATA Drives?

Apr 2, 2010

I installed debian 5.0.4 server on a PC that has both IDE and SATA controllers. I used an IDE HD to install the OS. The input device was a USB DVD unit. The IDE drive showed as /dev/hda and the 4 SATA HDs showed as /dev/sda1, /dev/sda2, /dev/sda3 and /dev/sda4. After the OS was installed the reboot started which brought up an error: GRUB GRUB Read Error

I then disconnected the SATA HDs and rebooted successfully. So no PROBLEMS with just the IDE drive connected, grub works fine. If I reconnect the SATA HDs though grub fails with:

GRUB GRUB Read Error

The problem originated when the installation got to the GRUB implementation. Here the installer engine asked me If I wanted GRUB to be installed on the MBR, to which I said YES. The installer had listed the IDE drive (/dev/hda) before the SATA drives (/dev/sda, /dev/sdb, /dev/sdc, /dev/sdd). After the installation finished and the machine was restarted, BIOS looked at the SATA drives first could not find the grub stages and it displayed an "Read Error".

After realising what was happening I looked at the BIOS settings to see if the HD booting sequence could be altered. The BIOS did indeed list the 4 SATA drives first and the IDE HD last. BUT it would not let me alter the booting sequence. So I was stuck with what the BIOS doing. So I decided I take the IDE drive out and create a 20G partition on the first SATA to accommodate the OS. So now everything works OK.

OpenSUSE Install :: Error 11.2 On Raid 0 / EM2001 2 Poorts PCI Controller SATA Fails?

Mar 1, 2010

I want to stop using Windows because it sucks so i have downloaded all kind of distibutions from Linux. They give all the same error because it seems Linux has problems with Fakeraid. Now i have running OpenSuse in VmWare 7.0.1 but i want it as the only OS.

The installation goes fine but in the end it gives a Grub error because it cannot create the bootloader. It seems to be a common problem and i have done all the steps that i could find on Google.

I have two raid controllers. One is integrated in the mainboard from Asrock ALiveNF7G-HD720p R5.0 and OpenSuse sees it as a Jmicron controller.I have bought also a EM2001 2 Poorts PCI Controller SATA card with two harddisks in Raid 0 because Linux failed to install on the JMicron. On the EM2001 2 Poorts PCI Controller SATA it also fails with the same error.

I want OpenSuse 11.2 working on Raid 0. I know it must be some simple commands in the terminal through a live cd to correct the bootloader and do it manualy by Linux users but i'm a Windows user.

Can somewhone please tell me the exact steps and commands to install Linux on Raid 0 Fakeraid?

General :: SATA Drives Or Chipset Throwing DRDY Error And ICRC ABRT?

Mar 18, 2010

I have an SD-VIA-1A2S PCI card with 2 sata ports (and one ATA-133 that isn't used). Two new Western Digital Caviar Green drives (WD10EARS 1TB) throw repeated errors in kern.log (removed date/time/host info for brevity):

[ 7.376475] ata2.00: exception Emask 0x12 SAct 0x0 SErr 0x1000500 action 0x6
[ 7.376480] ata2.00: BMDMA stat 0x5
[ 7.376483] ata2: SError: { UnrecovData Proto TrStaTrns }[code]....

I'm using Ubuntu 9.04 - 2.6.28-18-generic, though I have tried live cds of Ubuntu 9.10, Fedora 12 and OpenSUSE 11.2 - all running various 2.6.31 kernels - and all received the same error.Based on testing these drives and this card in two other machines and combos of connecting the drives directly to the motherboard or the add-in card, I'm relatively convinced that it's the VIA chipset that is the problem.Another computer that also has an onboard VIA SATA chipset (like the add-in card) produces the same errors when the drives are directly on that motherboard. I have been able to verify that the drives are perfectly good, and I tried everything I can think of in terms of swapping cables, psu isn't overloaded, etc.

The error happens on boot once or twice, after using fdisk on the drive once or twice, and constantly when attempting to sync a new mdadm raid 1 array created on the two drives.I'm completely open to buying a new PCI add-in card if someone can recommend one with 2 internal sata ports that works well in Debian/Ubuntu.

Ubuntu :: Getting Different SATA Error "softreset Failed"

Dec 15, 2010

I am not sure how to simply explain my dilemma/what I am trying to do, so here is a breakdown: My ComputerIn my computer, I have an ASUS M4A78L-M motherboard which has the problematic "AMD SB710" south bridge. I have an AMD Athlon II X3 440 processor, and I unlocked it to a Phenom II X4 B40, and over clocked it to 3.55 GHZ, and it is fully stable (Best $75 bucks I've spent). I have 3 hard drives, one is a Sata drive made by a company called excelstor technologies and is 250GB (Here is the OEMs data sheet: [URL].... I have XP and 7-64bit installed with the windows boot loader on that. I have a 120GB Toshiba IDE hard drive from a laptop, and an IDE to SATA converter, and it is mounted with brackets internally, and this is only used for storage.

Lastly, I have a 1 TB Seagate drive that I use for Ubuntu 10.04 64-bit, this is my default boot device, and I am using GRUB (not GRUB 2). I also have an Nvidia 9800GT, and 4GB of DDR2-5300 (I chose slow good RAM thats slow, so I can over clock my processor higher). I also have 2 old IDE CD/DVD drives/Burners. My Relationship With UbuntuUbuntu boots and runs fine off a USB Flash Drive, Memory Card, or CD/DVD, but I had a lot of hassle getting it to install. I was never able to boot outside of recovery mode, and when I would start recovery mode, and about 80% of the time I would get a SATA link failure (I thought it was the cheap IDE to SATA adapter, but I disconnected that, and it makes no difference), and my computer would stop booting at that.....

CentOS 5 Hardware :: Error Installing CentOS 5.2 On ICH7R With 4 SATA HDDs RAID 5?

The installer can't see my raid controller (I assume) as I'm getting the following error:"Error opening /dev/mapper/isw_jbhgjgjj_Vol0: No such device or address"It just sees them as 4 individual drives: sda, sdb, sdc and sdd.Please note that I have set up the RAID 5 in the controller bios interface and the image name is Vol0, which it seems that it tries to load but for some particular reason it can't.I have also tried different bios settings and nothing worked.

Ubuntu :: Booting The USB2 And E-SATA?

Mar 20, 2010

I've been using a 2GB flash drive with Ubuntu on it for the last few weeks, instead of a full install as my main laptop is down with hardware failure. I'm finding that it works so well, that I'm tempted to go this way permanently. I really like having the same setup on whatever machine I happen to be using. Anyway, If I was to do this I'd need a drive with more space and I've come across portable SSD drives that support connections over both USB & E-Sata.

If I had Ubuntu installed on such a drive would it be able to boot over both kinds of connections or would I be limited to whatever connection I did the install over? My work laptop supports e-sata, so I'd like to use that mainly but I would like to be able to use USB when e-sata isn't available.
