  • Win7 - DVD drive spins up but fails to read, fails write

    - by MA
    Running Windows 7 x64. DVD drive is a BenQ DC DQ60 ATA dvd-dl rw. Everything functions correctly in linux, and I can boot to cd/dvds, so the drive itself does work. Symptom: when I insert any CD or DVD (burned or retail), the drive spins up the disk, and (usually) displays the disk title in My Computer, but just continues to spin indefinitely. I cannot browse the disk in the drive, install from it, or read anything.

  • Is bigger capacity ram faster then smaller capacity ram for same clock and CL?

    - by didibus
    I know that bigger capacity hard-drives with the same RPM are faster then smaller capacity hard-drives. I was wondering if the same is true for ram. Given two ram clocked at 1600mhz and with identical CLs: 9-9-9-24. Is a 2x8 going to perform better then a 2x4 ? Note that I am not asking if having more ram will improve the performance of my PC, I'm asking if the bigger capacity ram performs better. Thank You.

  • Troubleshooting major performance issue: Is culprit Intel RST, Hard drive, or something else?

    - by Sean Killeen
    The Setup I have the following components that come into play in this situation: ASUS P8Z68 V/PRO motherboard a RAID1 configuration (1x 1TB drive, 1 x 2TB drive -- I explain below), accelerated with an SSD using Intel's RST software, and 1 TB drive standing by as a spare. Core i7 2600k 32 GB RAM Windows 8.1 This box was designed to be beast, and until just recently, was very good at being just that. What's Happening The system has slowed to a crawl whenever it touches the disk. Things appear to work at normal speed when dealing with memory. For example, typing this is fine, but saving it to disk from notepad gave me a 5-7 second pause when clicking save. The disks appear to be at 100% all the time (e.g. the light on the disk access on the PC is solidly on -- not even any flashing) In ProcExp it appears that the disk is barely being utilized at all: Intel RST reports that everything is fine: Other Details Prior to this happening, RST had reported that my drives were failing (one went bad, one was throwing SMART events). This made sense; they were at the tail end of their warranty and the PC is on almost all the time. I RMA'd the drives via Seagate. In the meantime, I'd purchased a 2TB drive because I didn't realize that the 1TB drives were under warranty. I figured I'd replace the other 1 TB drive with another 2 TB when it died but then discovered the warranty. AFAIK, I haven't done any major updates since 8.1 and it worked fine after those. Question(s) How can I troubleshoot this? What is the best way to try to figure out why disks are being maxed out despite the OS reporting barely any disk usage and that everything is OK? Given the failures, etc. that I describe above, is it possible that the problem could be the I/O on the motherboard itself? If so, how would I even be able to diagnose it? I'm betting the drives that Seagate gave me are refurbished (didn't think to look; that's dumb). Is it possible that the same model drive, refurbished, could somehow cause this? In terms of how RAID1 works, is it possible that one drive is "falling behind" somehow, and that the RAID1 is constantly trying to fix the mirroring? If so, this seems like Intel RST would report on it, but I wanted to consider it as an option.

  • How should I buy a laptop with a solid state hard drive?

    - by Kragen
    I'm looking into buying myself a new laptop, and I'd like to get a solid state hard drive. I've been looking around for laptops and I can see a few are solid with solid state hard drives, however the choice generaly tends to be very limited compared with standard drives. What is the best way to go about buying a laptop with a solid state hard drive? Should I look at laptops that come with SSD's included, or am I better off looking at "normal" laptops, and buying the SSD separately and fitting it myself?

    I wish to share my hard drives between my two computers but I seem to be running along some sort of error... my windows XP Computer is picking up my "XGaming" hard drive but when clicked it says access is denied, despite there is no password set up(I followed this: http://www.howtogeek.com/howto/windows-7/share-files-and-printers-between-windows-7-and-xp/) I also tried to share my C and J drives on my windows XP computer but my windows 7 computer doesn't seem to even detect them!

  • T42 Thinkpad, USB boot, CF for programs and storage?

    - by Tom K.
    Is this feasible? I have a Thinkpad T40. I'd like to get one of the tiny USB drives (like the Verbatim Store 'n' Stay series) of sufficient size to handle basic Linux OS booting (8GB?), then put 16Gb or greater memory card (SD or CF) in the PCMCIA slot with appropriate adapter for additional application programs and data storage. I know I could get a used or refurb HD, but I've had reliability issues in the past. I don't believe that new IDE drives are available.

  • How many disks is too many in this RAID 5 configuration??

    - by Tom
    HP 2012i SAN, 7 disks in RAID 5 with 1 hot spare, took several days to expand the volume from 5 to 7 300GB SAS drives. Looking for suggestions about when and how I would determine that having 2 volumes in the SAN, each one with RAID 5, would be better?? I can add 3 more drives to the controller someday, the SAN is used for ESX/vSphere VMs. Thank you...

  • Mounting a drive in Ubuntu 9.10 (Karmic Koala)

    - by morpheous
    I have just installed Ubuntu on a machine that previously had XP installed on it. The machine has 2 HDD (hard disk drives). I opted to install Ubuntu completely over XP. I am new to Linux, and I am still learning how to navigate teh file structure. However, AFAICT), there is only one drive. I want to be able to store programs etc on the first drive, and store data (program output etc) on the second drive. It appears Ubuntu is not aware that I have 2 drives (on XP, these were drives C and D). How can I mount the second drive (ideally, I want to do this automatically on login, so that the drive is available to me whenever I login - withou manual intervention from me) In XP, I could refer to files on a specific drive by prefixing with the drive letter (e.g. c:\foobar.cpp and d:\foobar.dat). I suspect the notation on ubuntu is different. How may I specify specific files on different drives? Last but notbthe least (a bit unrelated to previous questions). This relates to direcory structure again. I am a developer (C++ for desktops and PHP for websites), I want to install the following apps/ libraries. i). Apache 2.2 ii). PHP 5.2.11 iii). MySQL (5.1) iv). SVN v). Netbeans vi). C++ development tools (gcc, gdb, emacs etc) vii). QT toolkit viii). Some miscellaeous scientific software (e.g. www.r-project.org, www.gnu.org/software/octave/) I would be grateful if a someone can recommend a directory layout for these applications. Regarding development, I would also be grateful if someone could point out where to store my project and source files i.e: (i) *.cpp, *.hpp, *.mak files for cpp projects (ii) individual websites On my XP machine the layout for C++ dev was like this: c:\dev\devtools (common libs and headers etc) c:\dev\workarea (root folder for projects) c:\dev\workarea\c++ (c++ projects) c:\dev\workarea\websites (web projects) I would like to create a similar folder structure on the linux machine, but its not clear whether to place these folders under /, /usr, /home or swomewhere else (there seems to be abffling number of choices, so I want to get it "right" first time - i.e having a directory structure that most developer use, so it is easier when communicating with other ubuntu/linux developers)

  • Can't make VM off Windows XP

    - by WebDevHobo
    I've got a copy of WinXP off of MSDNAA, with a key. I've mounted it to my CD-drive, and now I'm trying to make it in to a VM. The problem is, it seems that the thing is constantly trying to connect to a DHCP server, fails to connect and then decides no operating system was found. The file I got off MSDNAA was an .img file, so I had to mount it to a virtual CD drive. VmWare workstation comes with a Windows XP iso, tried that, also failed.

  • Using USB HDD with Arcserve / Brightstor

    - by Hilt86
    I am having an issue configuring a standard USB HDD for use with CA Arcserve Brightstor 11.5 SP2 : Under the device list it shows a USB device category but none of my USB drives are listed underneath. I have attempted to "scan devices" but it makes no difference. I have also tried restarting the tape engine to no avail! Is anyone successfully using USB drives with Brightstor?
