• What contributes to smooth online video streaming?

  - by Wesley

  I had a general question about streaming videos online; in particular, on YouTube. What really is required to smoothly stream videos at 360p or 480p? Then for that HD goodness, what really allows a computer to smoothly stream 720p and 1080p? I'm not too sure whether it's to do with the CPU (speed, # cores, cache size), GPU (chipset, VRAM, memory type) or even HDD (IDE vs SATA). What contributes to the ability to stream regular videos and, furthermore, high-definition videos online?

• Clonezilla is not able to clone a RAID 1 disk

  - by Adrian

  I have a HP Server DL320 G5. There are two SATA hard disks configured as RAID 1 through HP embedded RAID controller. Server OS is running GNU/Linux (Fedora) Server booted up with clonezilla live CD. The image will be stored on a NAS connected through NFS. Clonezilla could mount the NFS share and could see the two hard disks /dev/sda and /dev/sdb. I selected /dev/sda for disk cloning. However I could not see the cloning progress and got straight into a prompt for reboot, poweroff, command line I tried to select /dev/sdb but the same issue.

• aligning truecrypt partition on 1.5TB 4kB sector drive

  - by pQd

  hi, aligning partitions to start at real physical sector of ssds / stripped raids / 4kB drives is a 'good thing to do'. but i've run into a problems when trying to do it for a truecrypt partition that will contain ext3 on it. or so it seems. when drive is question is partitioned properly and formatted with ext3 i get very reasonable write speeds around 70-80MB/s, but when i put truecrypt and ext3 on the top of it write performance becomes very unstable and goes between 1-25MB/s with very high io-wait. on the same server i dont have any performance issues with ext3 on the top of truecrypt on regular 512B-sector 500GB sata disks. so my best guess is that iowaits are caused by misalignment but i cannot really find reliable information on how to calculate optimal partition beginning. i've tried to start it at 128 logical sector, i've also tried 8132 sector as suggested here but both gave me very bad and unstable performance. do you have any experience with similar setup? thanks!

• How to move a windows machine properly from RAID 1 to raid 10?

  - by goober

  Goal I would like to add two more hard drives to my current RAID 1 setup and create a RAID 0 setup on top of the two RAID 1 setups (which I believe is referred to as "RAID 10"). Components Involved Intel P68 Chipset Motherboard 4 SATA ports that can be configured for Raid An intel SSD cache that sits in front of the RAID, and a 64 GB SSD configured in that manner Two 1TB HDDs configured in RAID 1 OS: Windows 7 Professional Resources Consulted so far I found a great resource on LinuxQuestions.org for a good "best practices" process for Linux machines, but I'd like to develop a similar process that I know works on Windows Machines.

• Clicking or Knocking with Seagate HD

  - by Daniel A. White

  My laptop's main HD makes a clicking or knocking sound when Windows or the Bios tries to access it. I put it into a SATA dock and it sounds perfectly fine when spinning up, but after Windows tries to access it, it becomes a repetitive clicking or knocking sound. Does anyone know any tips that might help me access my data? I have most of it backed up, but I would still like to Ghost it before I send it off for repairs. I know my laptop is still under warranty.

• Can I rebuild degraded RAID1 on a SAS 5 i controller with a larger mirror drive size?

  - by Kenny

  Hi, A drive failed on a Dell SAS 5i controller - see controller bios screengrab: http://imagebin.ca/view/SkZbszA.html The primary is a 160GB 10k sata drive. I added a 250GB 7k rpm drive in the hope that the array would rebuild onto this drive. This did not happen. (assuming that the controller would just operate at the speed of the slowest drive) The controller could see the new drive, but it didn't automatically rebuild the raid1 onto this drive. (my assumption is that it did not do this rebuild as the drive sizes are different). There was an option to add the new drive to the existing raid1 array - but when I tried this a message appeared stating that all data on the array would be lost. (I didn't get a screenshot of this message, I will later) Should the SAS 5i allow me to rebuild the array onto a larger drive? Is the option to add the drive to the array the right way to go? Many thanks!

• Can I use dmraid instead of md (mdadm) to make software RAID-1 and RAID-1+0 volumes?

  - by Don MacAskill

  On a related question about SSDs and TRIM (see: Possible to get SSD TRIM (discard) working on ext4 + LVM + software RAID in Linux? ), it turns out that dmraid may now (or shortly) support TRIM on RAID-1. Typically, we've used md (via mdadm) to create our RAID-1 volumes, then used LVM to create volume groups, then formatted with the file system of our choice (ext4 lately). We've been doing this for years, and Google & ServerFault searches seem to confirm this is the most common way of doing software RAID with volume management. Google searches seem to suggest that dmraid is use for so-called 'fakeRAID' configurations where there's some level of hardware 'help' in the form of RAID BIOS in the controller, which we don't have (and don't want to use - we'd like a fully software solution). Since we'd like to use TRIM on our SSDs, and since md doesn't seem to (yet?) support TRIM, I'm wondering if it's possible to use dmraid instead of md to create RAID-1 (and RAID-1+0) volumes in software, with no hardware support (ie, just plugged into a dumb SATA/SAS bus)?

• which server is best for me??

  - by mathew

  I am looking for a best hosting service for my website. My website is a PHP MySQl driven site which hase got site scrapping for more than 10 websites and near about 8-10 API pursing and some about 150 mb dat file reading(from local hard drive), and also one rss pursing,Live graph from other sites, geo map from Google,Map api from Google and so on. one widget which real-time result for any one who chose the same. so my question is which is best option for me. actually I am considering softlayer cloud as they are pretty cheap and more facilities than rackspace. another option is a dedicated server which has 2 single core processor, 4GB ram and 250GB sata II. with 100 mbps uplink. so please tell me which will be the best option?? I heard that dedicated server has lots of limitations than cloud. but for cloud they uses SAN for storage so I am afraid the reading proces for database may be bit slower...and their basic plan ram is only 1 GB.

• BSOD on windows 7 with SSD during boot after improper shutdown

  - by Bob

  I have a BSOD on windows 7 with SSD during boot after improper shutdown (while windows animation logo is moving). The computer restart imediatly after BSOD, and windows proposes to launch startup repair (if i do it, it takes +-5min and fixes the problem : computer starts normally). However, after any new improper shutdown, i got the same problem. Remarks: If i unplug, re-plug the SSD whyle system is shutdown, i have the same problem. If i reproduce the situation with old HDD, i havn't the problem Previously, i had a different problem: BSOD when waking up after sleep, which was fixed by installing drivers (ethernet, usb, graphic card) I have made ram chech and ssd check and found no problems Starting with safe mode after improper shutdown causes a BSOD at loading of classpnp.sys Configuration: System: HP compaq 8510p SSD: OCZ vertex-2 2.5 Boot options: SATA native mode - Enable, HDD transalation mode - LBA-assisted

• Stuttery 1080p playback on decent system

  - by Leo

  We have a media center system that was recently built. It works well for all types of content, however it has issues with 1080p content. 720p plays fine. I have tried VLC, ffdshow and finally, CoreAVC. CoreAVC plays the best however it still eventually loses sync due to stutter - this does not happen on other systems with the same file. Specs: Asrock 4core-2dual sata PCI Express ATI 2400 HD 1.5GB DDR 2100 Intel Pentium E5300 120GB Maxtor Diamondmax PATA Any ideas?

• Removing RAID on a DELL power-edge server

  - by Simon Callan

  We have a Dell Power-edge T110 server, with either a PERC S100 or S300 raid controller (I suspect S100), and 2 x 500GB SATA hard discs. These discs are running in RAID-1 configuration, (either 1 or 2 virtual discs), and on top of this, we have the C and D drives. As we are running low on disc space, we are looking at dropping the RAID to get some disc space back. Is it possible to split the discs back into 2 seperate hards discs that the OS can see, without losing all the data on the drives? Even better, would it be possible to split the D: drive, leaving the OS C: drive in RAID1 configuration?

• Beeping Hard Disk - Seagate 250GB Momentus 5400.6

  - by Pez Cuckow

  I have been trying to repair a laptop that simply beeps instead of booting. After taking it apart I have now realised that it is the hard disk beeping. I know that sound strange but I guarantee that is what it is! (Currently powered on it's own with a Sata Mains lead). The beeping is slightly faster than one per second there is a link to a recording below: http://www.pezcuckow.com/files/BeepingHardDisk.m4a This recording was made resting the mic on the hard disk while it was sat on a table on it's own, there are no speakers anywhere near, the sound is coming from the hard disk. Does anyone know what this beep means? Is the hard drive just dead, or is it fixable and the data recoverable? Many thanks,

• Error installing Windows7 64 bits on VirtualBox

  - by MetaDark

  I am trying to set up Windows in Virtual Box, so I don't need to reboot in the rare occasion that I actually need it. The problem is, Virtual Box doesn't preform any errors when I insert the 32bit installation CD but when I try to use the 64bit installation; What!? I am already using the installation disc! I've checked my BIOS to see if I have SVM (AMD's version of VT) disabled and all I see is "Enabled" I have a K9N6PGM2-V2 motherboard A Triple Core AMD Athlon II A Nvdia NForce 430 integrated graphics card 4GB of RAM An 80GB IDE And a 1TB SATA I don't think the last three specifications matter but just in case XP I am pretty sure the CD isn't broken ( I am going to make sure in just a moment ), what could be the cause to this problem? Edit: The 64bit installation CD is not broken, but I found out when trying to install from the 32bit version that it's trying to upgrade, not preform a fresh install - Odd.

• Can't initialize drive in Windows 7

  - by Abe

  I have a 2.5" laptop harddrive that I plugged into my laptop through a SATA to USB cable. It's powered by an adapter to a normal wall-plug. I want to use it as an external harddrive. It wouldn't initialize (Device is not ready), so as suggested in some instructions I found I uninstalled the drivers, unplugged it and plugged it back in. That worked, and I initialized the drive and formatted it. However I unplugged it after that and a few days later the same strategy does not work and I can't figure out how to use the drive. I can't initialize it and it doesn't show up in my computer.

• Does a Samsung G3 Station external hard drive stop working when power supply is too high?

  - by Cacovsky

  I have a Samsung G3 Station 2TB external hard drive (link to PDF specs here). It was working perfectly when I accidentally plugged it in my notebook's power source. The notebook's power source is 19V/3.42A. The hard drive's is 12V/2A and I know that, inside its case, there is regular 2TB SATA drive, along with some sort of adapter. Does this adapter has some kind of power protection? I opened the case and the hard drive board smells bad. Does my data is forever lost or can I replace its board?

• Hypertransport sync flood error

  - by Carl B

  What is it? And what causes it? Is it only for uncorrectable DIMM Errors(Troubleshooting DIMM errors)? When an UCE occurs, the memory controller causes an immediate reboot of the system. During reboot, the BIOS checks the Machine Check registers and determines that the previous reboot was due to an UCE, then reports this in POST after the memtest stage: A Hypertransport Sync Flood occurred on last boot 3 BIOS reports this event in the service processor’s system event log (SEL) as shown in the sample IPMItool output There are what seems to be some suggested answers to include Bad Caps Bios verisons (happens in one version not the other) Graphics card issues Lack of power to the CPU The list of possible generators seems to target everything but the computer case.

• Virtualizing OpenSolaris with physical disks

  - by Fionna Davids

  I currently have a OpenSolaris installation with a ~1Tb RaidZ volume made up of 3 500Gb hard drives. This is on commodity hardware (ASUS NVIDIA based board on Intel Core 2). I'm wondering whether anyone knows if XenServer or Oracle VM can be used to install 2009.06 and get given physical access to the three SATA drives so that I can continue to use the zpool and be able to use the Xen bits for other areas. I'm thinking of installing the JeOS version of OpenSolaris, have it manage just my ZFS volume and some other stuff for work(4GB), then have a Windows(2GB) and Linux(1GB) VM (theres 8Gb RAM on that box) virtualised for testing things. Currently I am using VirtualBox installed on OpenSolaris for the Windows and Linux testing but wondered if the above was a better alternative. Essentially, 3 Disks - OpenSolaris Guest VM, it loads the zpool and offers it to the other VMs via CIFS.

• How likely can my data be recovered after Windows CHKDSK performed on a degraded RAID 5 array?

  - by chrisling106

  Hello there, We have a RAID 5 setup with 3 SATA disks, #2 went down as reported on the pre-POST screen. Unfortunately, for some reason out of my control, the system was rebooted with a degraded RAID :-O Windows XP (64-bit) loaded, CHKDSK ran automatically and done its recovery! From that point onwards, the following error prompts every time even in Safe Mode: lsass.exe - The endpoint format is invalid I took those 3 disks to the data recovery expert and need to wait at least 2-4 days for results. There are 2 VMs on multiple files stored in this RAID 5 array, and there's no backup! Sorry, I just inherited the system from an ex-staff who has left the company 2 months before I joined. How likely the data can be recovered?

• Acer Aspire 5719 with Windows XP does not boot

  - by Sri

  Hi, I have an Acer Aspire 5710 which came pre-loaded with Windows Vista. O/S has been changed to Win SXP SP2 and was working fine till today. The laptop starts up and then hangs (does not reach till the Windows screen). Have tried the following Repair with XP CD. Re-install with XP CD (In both cases the error "No hard disk" is displayed.) Tried F5/F8 to boot with other options. Guess the hard-disk is not being recognised. The 160 Gb SATA disk is shown as IDE0 in the Phoenix Bios. There is no floppy drive. Any suggestions. Thanks, Sri.

• Accessing multiple local HD's or RAID with ESXi 4.0

  - by Shawn Anderson

  How to I get additional HD's to be recognized and used by ESXi 4.0. When I purchased my system I had two 2TB HD's, but when I installed ESXi it only recognized one of them. I'm happy to get whatever number of drives that I need (I have a four bay SATA in my Dell T310). What are some options? RAID? If so, is it supported. I guess I would need hardware instead of software since ESXi is so small. The VMWare forums (where I've lived for the last two days) are a charlie foxtrot of outdated and conflicting info. I want to utilize my T310, with 32 GB RAM, 2.8GHz quad core to run many lab Windows VM's. I don't need production level availability but I do want decent performance, even though it's in a lab environment. A huge thanks to Jim B., Zypher, Helvick, and Jeff Hengesbach who posted answers to my earlier predecessor question on why ESXi was so sluggish.

• Xenserver boot error

  - by Adrian

  I'm trying to get Xenserver 5.5 running on a spare computer here, hardware specs: Intel Q6600, 4GB Ram, and Gigabyte GA-P35-DS3R motherboard Xenserver itself installs fine onto a 150GB sata hdd, however it fails to boot whatsoever, giving this garbled mess: http://img697.imageshack.us/img697/9918/biosi.jpg it's not frozen because if I press enter it just prints a different garble and it also says "could not find kernel image". The strangest thing is if I put that hdd in my desktop and assign it to a VMWare desktop vm (under the ESX profile no less) it boots perfectly... leading me to believe there are no problems with the install or the hdd itself. From what I can tell the error seems to be occuring completely seperately to Xenserver, in the bootloader extlinux?. If there was a motherboard compatibility issue I would think it would also have manifested during installation, and the fact the problem seems to be with the booting into Xen makes me doubt this. Any ideas guys? (I'm using Xen because it can do PCI passthrough without VT-d.)

• In terms of performance, which processor is more suitable?

  - by Roberts

  My computer specs: Motherboard: Gigabyte GA-945PL-S3 OS: Microsoft Windows 7 Ultimate CPU Socket: LGA775 CPU: Intel® Core™2 Duo Processor E4300 (2M Cache, 1.80 GHz, 800 MHz FSB) After I bought new hard drive (Western Digital 250GB, 7200rpm, 32MB, Sata III, Caviar Blue, WD2500AAKX) I saw that my processor temperature started to raise to higher value then before. Now while surfing internet it goes to 70°C. Cleaned my motherboard - nothing; cleaned fan - nothing; replaced thermal paste - nothing; replaced thermal paste with care - still nothing. So I went to friend just to check if he doesn't have any spear fan, and he did. But with fan he had another processor that he didn't need and he wanted to give it to me, but I told him that I will think about this. So my CPU, he's CPU (Intel® Pentium® D Processor 820 (2M Cache, 2.80 GHz, 800 MHz FSB)). Question: which proccesor is better for gaming and for recording games?

• Battery backed write cache behavior upon disk change

  - by Halfgaar

  We use 3ware Inc 9650SE SATA-II RAID PCIe RAID controllers with battery backed write cache. Our spare hardware has the same controller. I was wondering; are these controllers smart enough not to sync the cache when the disks have been changed? For example, if I deploy one of those spare machines by putting in the disks of another machine and that spare machine still has pending writes, will it be smart enough not to perform those writes on the replaced array? Edit: my scenario is not really made clear, so let me give an example: server1 goes down because of power supply failure. I put the disks in server2 and start. I repair server1 I put the disks back from server2 in server1 (it's not relevant right now that in reality I would probably keep server2 running). If server1 doesn't have safeguards, it will write to the array, thinking it's simply powering up again, corrupting it.

• Reliable Linux RAID Card

  - by Chris S

  Can anyone recommend an appropriate RAID card for use under Linux (Ubuntu)? I have three Western Digital SATA drives, and would like to setup either RAID-1 or RAID-5. Software RAID has been very flakey and unreliable for me (e.g. it doesn't seem to mirror the boot partition). Unfortunately, most RAID cards I've seen online don't mention any Linux driver support. Would most cards work in Linux, or do I have to look at a select few that explicitly support Linux?
