  • What processes would make the selling of a hard drive that previously held sensitive data justifiable? [closed]

    - by user12583188
    Possible Duplicate: Securely erasing all data from a hard drive In my personal collection are an increasing number of relatively new drives, only put on the shelf due to upgrades; in the past I have never sold hard drives with used machines for fear of having the encrypted password databases that have been stored on them compromised, but as their numbers increase I find myself more tempted to do so (due to the $$$ I know they're worth on the used market). What tools then exist to make the recovery of data from said drives difficult to the extent that selling them could be justified? Another way of saying this would be: what tools/method exist for making the attempts at recovery of any data previously stored on a certain drive impractical? I assume that it is always possible to recover data from a drive that is in working order. I assume also there are some methods for preventing recovery of data due a program called dban, and one particular feature in macOSX that deals with permanently deleting data from a disk.

  • Extract X11 configuration information from running instance.

    - by kasterma
    Since I had a hard disk die on me, I figured I could easily try some other OS (I usually run Ubuntu). Turns out that Ubuntu flawlessly recognizes my video card and monitor (X11 works right out of the box), and none of the other systems I tried gets anything working (I tried CentOS and FreeBSD). In my now working version of Ubuntu I cannot find a configuration file with information I could try to use with one of the other versions, which makes me guess that it just detects the hardware every time. Can I extract its choice for drivers and configuration options somehow (so I can try these same options in the other systems)?

  • 8GB, but have to run Windows Xp (32 Bit). Anything I can do with the additional memory?

    - by user12889
    I ordered a new computer with 8GB RAM with the plan to run Windows 7, 64Bit. Turns out now, that I need to run a 32Bit OS (XP or 7) due to some software which does not run on 64Bit yet (not even with any of the available compatibility settings / modes). Is there anything I can do with the memory above 4GB in this scenario? I'm willing to consider creative solutions like running a hypervisor under XP that offers the memory as a RAM-Disk for swapping etc. ? The software that does not run on 64Bit is CISCO VPN (there seems to be a half-working solution for that) and CISCO IP phone / webcam integration "CISCO Unified Video Advantage" (there is apparently no solution for that).

  • How to Completely delete my USB thumbstick?

    - by Roi
    I own a Kingston thumb-stick. I have installed a Google Chrome OS image to it so I could try it out. When it did so, it created 3 partitions (I backed everything and the software that installed Chrome OS delete my thumb-stick completely and created 3 partitions). Now I want to get it back to 1 partition but when I go to Disk Management, it will not let me "extend" the partition. I have tried different partitioning tools but they didn't recognize my thumb-stick anyway. I have also tried DiskPart to no avail. Is there any software that will completely format my thumb-stick so I would only have 1 partition?

  • Our company has 100,000s+ photos, how to store and browse/find these efficiently?

    - by tobefound
    We currently store our photos in a structure like this: folder\1\10000 - 19999.JPG|ORF|TIF (10 000 files) folder\2\20000 - 29999.JPG|ORF|TIF (10 000 files) etc... They are stored on 4 different 2TB D-link NASes attached and shared on our office network (\\nas1, \\nas2, and so on...) Problems: 1) When a client (Windows only, Vista and 7) wishes to browse the let's say \\nas1\folder\1\ folder, performance is quite poor. A problem. List takes a long time to generate in explorer window. Even with icons turned off. 2) Initial access to the NAS itself is sometimes slow. Problem. SAN disks too expensive for us. Even with iSCSI interface/switch technology. I've read a lot of tech pages saying that storing 100 000+ files in one single folder shouldn't be a problem. But we don't dare go there now that we experience problems on a 10K level. All input greatly appreciated, /T

  • Deleting Windows 8 install

    - by Yann4
    I have a windows 7 pc, and I had installed windows 8 on an SSD, so it was the only partition on that SSD. I've now realised that I never use it, so I went to uninstall it and followed these steps. The PC now boots into 7, as expected, however I can't delete or format the drive that has windows 8 on it. The format dropdown selection is greyed out, and I tried to just simply delete all of the files and use the disk as is, but as windows 8 isn't there, I no longer have rights to delete all of the files, apparently. The drive in question has 3 partitions, one that I made for the win8 system, and 2 smaller system-created partitions (one 300MB recovery and 1 100MB EFI) How do I go about formatting the drive?

  • Lightweight alternative to R for RHEL?

    - by Eric Rath
    I want to use R for some statistical analysis of logfile information, but found that even the "limited" R-core RPM has a lot of dependencies not already installed. I don't want to install so many packages for a peripheral need. Are there lightweight alternatives for simple statistical analysis on RHEL 6? I have an R script that accepts on stdin a large set of values -- one value per line -- and prints out the min, max, mean, median, 95th percentile, and standard deviation. For more context, I'm using grep and awk to find GET requests for a particular path in our webserver log files, get the response times, and calculate the metrics listed above in order to measure the impact on performance of changes to a web application. I don't need any graphing capabilities, just simple computation. Is there something I've overlooked?

  • How does storage spaces decide where to put my files?

    - by George Duckett
    With Windows 8 Storage Spaces, you can lump many hard disks of varying types, speeds and sizes together to use as a single storage space / logical drive. How does Windows decide what to place where? For example will it move files about depending on frequency of access? Maybe splitting files frequently accessed together between hard disks etc. What does it optimize for? Speed, reliability, etc? If the above is asking too much, can I easily see where the files are physically (on which physical disk)?

  • PHP CPU utilization limit

    - by knightrider
    I have done some research on the net regarding the problem. My questions is NOT how to reduce cpu utilization by improving algorithm or improving the performance by using multitasking or limiting CPU per system user. I have a website where user logs in does some processing and logout. The site uses linux server, php and apache. The problem is that I cant control the amount of CPU allocated to each user. ie I want give a guarantee that a user will get say atleast 5% of CPU (assume total number of users is less than 20). How can I do this? Any solution (A php code, apache server settings, or any out of box soln) is welcomed. Thankyou very much for reading this :)

  • Opinion choosing Switch

  • Mysql skip-name-resolve

    - by user72459
    I had recently purchased a new server, and transferred all my accounts via WHM Transfer. The problem is that when WHM takes a daily backup, it outputs are message such as DBD::mysql::st execute failed: There is no such grant defined for user 'abc' on host 'myhostname' The problem is solved when I remove skip-name-resolve from my my.cnf file. Tough I dont find any differences in the speed (when I dont add it), it is often mentioned in forums that adding skip-name-resolve optimizes Mysql Performance. Does adding skip-name-resolve really help, if one has a Dedicated server?

  • How long does it take in practice to warm up large in-memory databases?

    - by Sim
    Companies such as Peak Hosting are offering 64 core machines with 512Gb RAM for $2K/month. This is a very interesting choice for in-memory databases such as Memcached/Redis as well as databases whose performance degrades rapidly when the data & indexes don't fit in RAM, such as MongoDB. My main concern with monster machines such as these is the time it takes to warm up an in-memory database. In my experience, theoretical metrics, e.g., that SATA can load 100Mb/sec, fall short of what happens in practice. Even at that rate, 100Mb/sec means that loading up 512Gb RAM machine from SATA disks can take over 1 1/2 hours (!). I am looking for real-world reports of warm-up times for machines with very large memory. Please, share details of the software on the machine, data size, storage configuration, e.g., SATA or SSD, network, hosting/cloud provider, if relevant, etc.

  • Provide credentials to process in a safe manner

    - by Erik Aigner
    On system startup I need to launch a process which requires credentials for other services (database etc.) to interact. I obviously don't want to store those on disk for security reasons. I'm trying to think of a way to provide those credentials to the process on launch - and on launch only. After that they should be only available to the process. Is this possible somehow? The bottom line is to make it as hard as possible for an intruder to get to those credentials.

  • ISCSI sessions appear from nowhere

    - by Maraca
    Hi, I am using Win2008 32bit Ent. running in Hyper-V with 2 LUNs over ISCSI connection (this is a MS cluster with one LUN being quorum and second as a storage). In ISCSI - target - details I see multiple sessions from same target (currently 7), however I am not sure where they are coming from as I have only one virtual NIC on this server. Sure enough 2 LUNs appear 7 times each in device manager or in disk manager. On the cluster partner however, I do not see that problem. There is only one session per target. Installing MPIO makes only difference - I am getting 8 sessions instead of 7 once I reboot. Does any one know what can cause this behavior?

  • Can I install linux has the host in a dell poweredge server (r710)?

    - by bksunday
    I might have a deal on dual six core poweredge server and I'm about to go test its performance but I'm wondering few things which I can't find answers for, and I can't test them before buying the machine. I don't want vmware at all so can I just wipe it and install linux instead, or is it embedded in some parts I have no access to. Will I still be able to update different firmwares (perc controllers, motherboard, etc) on this dell poweredge or does it require to have the vmware esxi installed as the host os. And optionally.. is there any foreseeable problems in doing so?

  • Windows 2003 Server - File Permissions

    - by nickstan
    I have a Windows 2003 web server with a tree of folders that contains around 100GB of small images. I need to update the permissions on this folder to add a new user with access. I tried to do this by right clicking on the folder and adding the new user but the process never completed. I left it running for around an hour but it started to heavily impact the peformance of the server. Is there any other way to change these folder permissions without affecting server performance? Many Thanks Nick

  • KDE Device Notifier and mounted volumes ownership and permissions

    - by nunomaltez
    Hi, When I plug an USB pen to my PC and mount the device using KDE's Device Notifier, the mounted device is owned by my user, who has write permissions. However, when I connect a USB harddisk and mount a partition in the same way, the mounted device is owned by root, and since the owner is the only one with write permissions I can't write to the disk. How do I configure the device notifier's actions to mount the HD with my user as owner, just like it mounts the USB pen? I'm using Fedora 9.

  • Which OS should I boot into for virtualization?

    - by acidzombie24
    This might be a silly question. I use windows 7 99% of the time. I run linux 10% of the time and XP 5% of the time. I am thinking about getting a Intel® Core™ i7-2600 Processor which has hardware support for virtualization. I dont think i want more than one partition. May have a swap partition. Which OS should I make my primary (and only) partition? I suspect windows7 if i am always using it as going through a linux layer would slow it down. Does it matter much which OS i use if i have hardware support for virtualization? At the moment I am using VMWare player. I suspect software doesnt effect performance?

  • Queue emails under linux

    - by md1337
    I have a slow distant mail relay server and a web application I'm using locks up when sending e-mails to that distant mail server, until the e-mail is sent. After the e-mail is sent the page comes back and the application is snappy again. SO I'm trying to set up a differed mail queue locally on the application server (linux) so that the application uses that instead of the distant mail server. My rationale is that e-mails would get queued up locally until they are processed by the distant mail server, but at least the application doesn't lock up. I have installed postfix and set up the relayhost setting to the distant mail server, but performance has not improved. What appears to happen is that postfix just forwards my SMTP instructions in real time and doesn't really queue them? What can I do? Thanks!

  • How can we recover/restore lost/overwritten data in our MSSQL 2008 table?

    - by TeTe
    I am in serious trouble and I am seeking professional advices here. We are using MSSQL server 2008. We removed primary key, replaced exiting data with new data resulted losing our critical business data in its child tables on MSSQL Server. It was completely human mistake and we didn't have disk failure. 1) The last backup file was a month ago which means it is useless. 2) We created Maintenance Plans to backup our database at 12AM everyday but those files are nohwere to be found 3) A friend of mine said we can recover from Transaction Logs. When I go to TaskRestore Transaction log is dimmed/disabled. 4) I checked ManagementMaintenance Plans. I can't find any restored point there. It seems that our maintenance plan hasn't been working. Is there any third party tool to recover lost/overwritten data from MSSQL table? Thanks a lot.
