• connections in FIN_WAIT and CLOSE_WAIT state

  - by Raj

  I would like to elaborate the setup so You guys can understand the question and answer more accurately. I have HAProxy as load-balancer, 4 webservers (apache 2.2.3) and one database server (MySQL 5). I am monitoring these servers by nagios. I have disabled the keepalive on apache as we have only 8GB of memory. Now what happens whenever I receive alerts for high memory and cpu utilization, I have observed that the connections from apache to database server hang in established mode (keepalive with timeout value of 7200) and at other side means connections between haproxy and apache shows status as FIN_WAIT on haproxy server and CLOSE_WAIT at apache side. I also see the huge memory swapping and apache taking the most of the memory. I did strace on apache process and did not find any information. strace gets attached to apache process but did not produce any output. The processlist on Mysql server show s those processes in sleep mode. The application on webserver is Magento a php application. if you need further information please let me know. Thanks.

• I recently converted my ex HDD from FAT32 to NTFS. now my pc doesn't find or pick up my NTFS HDD

  - by Jason Haniball

  I recently converted my external hard drive from FAT32 to NTFS using the Command Prompt. Everything was working fine, I copied a 7GB file to it and everything worked. The next day I switched on my PC, I couldn't and still can't find my external 1.5TB hard drive by my computer. I have about 500 to 800 GB of data on it that I really don't want to lose. Its a Iomega Seagate Freeagent HDD. Has no switch, it switched on automatically, don't know if that helps.

• WD: UDMA CRC Errors and Reallocated Sector

  - by Leo White

  I got a WD Caviar Black 1TB (WD1001FALS) and according to SMART, I got: one "Reallocated Sector" one "Reallocated Event" 26 UDMA CRC Errors in my drive but it's a "Pass" for the "SMART overall-health self assessment test". I think it's because of these, I'm having problems with Grub, and thus can't boot into any OS at all. Are these problems serious? According to "Warranty Services", my drive is still "In Limited Warranty". Would I be eligible for a replacement? FYI: I'm running Ubuntu 11.10. Any help will be appreciated. Thanks

• Preserve the state of the start screen

  - by axrwkr

  What would I need to do in order to cause the start screen to stay the way it was the last time I saw it when I go back to it? I've noticed that every time I leave the start screen it resets back to the beginning, this means that I need to scroll back to where I was to get the same view. I don't want to change the order of the applications on the start screen to accommodate this, I would much prefer it if I could find a way to make the start screen stay the way it was so I can move on from there and also if there was a way to jump to the beginning or the end of the list that would be great. I imagine I can just use the search feature to find a specific program, but that's just an extra step, almost as bad as having to scroll.

• How to automount a Truecrypt volume before login in Windows 7?

  - by nonoitall

  I have an external hard drive containing all my documents, and it is encrypted with a password via Truecrypt. I'd like my desktop computer at home to automatically mount the volume prior to my logging in (so that it can be used as my user folder) without asking me for a password. (Yes, the password can be saved in plain text on my desktop's hard drive - that's okay.) For the life of me, I can't figure out a way to do this that actually works though. Tried using the Task Scheduler to schedule a mount when the computer starts up, and it works, but the volume is only accessible by my user account after I log in. (Haven't tried every combination of users/options for the scheduled task, so maybe there's something else there I need to try.) Also tried adding a startup script for my user account that runs on login, which evidently is too late to set up the user's profile folder. Anybody ever successfully achieve this or something like it?

• How much data does windows write on boot

  - by soandos

  This question was inspired by Bob's comment to my answer here. On boot, windows writes files to the hard drive (I imagine this to be the case, as it has a way of detecting if the boot was previously interrupted by a hard power-off, and I am sure many other things). But assuming that there is a "smooth" boot, where there are no error, etc, and no logon scripts that run, and things like that, about how much (a few KB, a few MB, a few GB) data gets written to the drive? For simplicity's sake, assume that: hibernation is turned off windows 7 pagefile is turned off (does this matter right at boot, or only later?) How could one go about measuring this? Are there resources that have this information?

• When should I use SATA 6gb/s?

  - by Gili

  I purchased a Baraccuda hard-drive (model ST3000DM001) that supports a maximum read transfer rate of 210 MB/s and SATA 1.5/3/6 Gb/s. My motherboard has a limited number of 6 Gb/s ports so I'd like to reserve them for when it's really necessary. When does a hard-drive benefit from a SATA 6 Gb/s port? Doesn't it require a transfer speed of at least 375 MB/s to surpass the limit of SATA 3 Gb/s? Are there any other benefits of SATA 6 Gb/s vs 3 Gb/s ports?

• Windows update on netbook requires CD (hint, there's no CD drive)

  - by bwooceli

  An "Important" update for Microsoft Works (via Windows Update) on a Dell netbook gets about halfway through and then pops up with the super-awesome "Please insert Microsoft Works 9.0 disc" message. Of course, the netbook has no CD rom drive, there is no handy folder (that i can find) containing "Works9.msi", and I have no Works9 disc. It wouldn't be so bad, except the update keeps coming up everytime WU runs. Any suggestions?

• Automatically copy files to USB drive when connected

  - by Daphna

  I am looking for a solution for copying all the files from a specific directory on the hard drive, to a specific directory on a USB memory device, once this device is connected. I have a program that downloads podcast episodes for me. I would like these files to be automatically moved (or at least copied) to my mp3 player once I connect it to the computer. I have both windows xp and linux machines, so a solution for any of them will work for me.

• Survive a Software Audit

  - by rosepost1150

  I received a letter from Autodesk asking for a "License Assessment". I understand it as a software audit. They plan to do it remotely. The thing is, I'm a freelancer, I don't use any Software Asset Mangment software, and I just recently swap out my hard drive for a new one, and did a complete clean install, and then I received this request from Autodesk. There is almost nothing on my hard drive now. What do software auditors do when they experience this? Will they (are they allowed) to contact my clients (that info is all over the web..) to get information since they found nothing here?

• Extensive use of HDD after VmWare Player virtual machine is closed.

  - by Bobrovsky

  Each time I close virtual machine in VmWare Player I see extensive use of HDD in my system. Basically, whole system becomes unresponsive for about 5-7 minutes. Host system is Windows 7 Utimate x64 SP1 with 6 GB of memory, i3-M350 processor. Virtual machine is Windows XP SP3 x86 (2GB of memory allocated for VM). What can be the cause and what can I do to solve the issue? UPDATE: I am not shutting down the VM, I just close Player window and VM saves it's state. System becomes unresponsive right after VM have saved it state (as indicated by Player) and Player itself have closed.

• Installed Ubuntu 11.10, getting hard disk health warnings

  - by Brad

  I'm getting hard disk health problem warnings... When I click the "examine" button the disk utility pops up. None of my drives are reporting any major issues, and the very first drive doesn't even have a SMART button. I don't really care if one of the drives is crashing, I've got everything backed up, but I just want to know how to stop these god forsaken message boxes from popping up randomly. I have already gone into the Disk Utility and checked "do not notify me if this drive is failing" on all of them except the one that doesn't have the SMART button. I've googled about as much as I can for one day.

• How to image an fresh hard drive

  - by JoelHess

  I'm looking for something that can drop an image of Windows onto an uninitialized Hard Drive. I have new units that haven't even had the partition table created on them, and I'm trying to come up with a one (or two) step process for getting a disk image onto them. I've tried clonezilla, but that doesn't seem to like the lack of partition table, and as far as I can tell, Acronis doesn't work either.

• Asus ux31e zenbook SSD non-standard / cant upgrade hdd?

  - by FstaRocka

  I bought a ux31e asus zenbook, and the drive crashed last week. I just cancelled an mSata ssd order because I fear asus has used a non standard ssd!!! what a bunch of crooks, ive lost all my respect for this company! Can anyone confirm what and why? My SSD model is xm11 128gb - it looks like a ram chip and only has two tongues with 12 and 6 pins respectively. The drive I was about to order mSata had 8 where mine had 6 - i never bothered counting the rest. This article seems to confirm!

• recovering vm data from crashed XenServer install

  - by user58983

  We're using xenserver 5.6 from citrix to run our virtual machines. The box is old and creaky, and the hard drive went. (We had a super limited budget of $0 at the time). Turns out the only machine on there we actually needed, was the only one not backed up... anyway, we've replace the hard drive, and reinstalled xensever. however while trying to find our old vm disk images, i have no idea where they sit, and i'm beginning to think they're on a lvm partition? is there anyway to access the disk images from the old vm's on this hard disk, which is attached to the xenserver machine via a usb-sata converter?

• Safest snapshot of a failing harddrive?

  - by ironfroggy

  I have a headless machine that stopped booting, so I pulled it out for diagnostics and got a message that one of the harddrives was about to fail, so I pulled them all out and I need to get everything off, before figuring out which I need to get rid of. I wasn't sure which drive was failing, because it only said "Harddrive 1" and I don't know which it referred to. I'm wondering the best way to get everything off. I'm worried if I copy everything, I could get corrupt data and not realize some files are wrong until the drive is completely out of commission. What are my best options to get everything off in a way I can safely move to new storage?

• Would SSD drives benefit from a non-default allocation unit size?

  - by davebug

  The default allocation unit size recommended when formatting a drive in our current set-up is 4096 bytes. I understand the basics of the pros and cons of larger and smaller sizes (performance boost vs. space preservation) but it seems the benefits of a solid state drive (seek times massively lower than hard disks) may create a situation where a much smaller allocation size is not detrimental. Were this the case it would at least partially help to overcome the disadvantage of SSD (massively higher prices per GB). Is there a way to determine the 'cost' of smaller allocation sizes specifically related to seek times? Or are there any studies or articles recommending a change from the default based on this newer tech? (Assume the most average scattering of sizes program files, OS files, data, mp3s, text files, etc.)

• What's a worthwhile test for a new HD?

  - by Michael Kohne

  I work for a company that uses standard 2.5" SATA HD's in our product. We presently test them by running the Linux 'badblocks -w' command on them when we get them - but they are 160 gig drives, so that takes like 5 hours (we boot parted magic onto a PC to do the scan). We don't actually build that many systems at a time, so this doable, but seriously annoying. Is there any research or anecdotal evidence on what a good incoming test for a hard drive should be? I'm thinking that we should just wipe them with all zeros, write out our image, and do a full drive read back. That would end up being only about 1 hour 45 minutes total. Given that drives do block remapping on their own, would what I've proposed show up any infant mortality just as well as running badblocks?

• Why do SSD drives get so much more expensive as they get larger?

  - by futuraprime

  Normal HDD costs go up very little as drives get larger. For example, an average 1TB drive costs a little under $90, 2TB costs a little over $100, and a 3TB drive costs close to $150. For HDDs, the cost per GB goes down as the number of GB goes up. SSD costs don't work like this: a 128GB SSD goes for $120ish, 256GB goes for $250ish, and 512GB drives get up to $600. The cost per GB goes up as the number of GB rises. What is it about SSDs that makes them so much costlier as they get larger?

• Putting two physical hard drives in a single 2.5" bay?

  - by dgw

  My crazy brain came up with this ridiculous idea. "Why can't I have a single 2.5" drive device that actually contains two independent hard drives? I want RAID 1 data mirroring and the security of having redundant drives. This is a thing that must exist!" To be clear, I am not asking if I can somehow shoehorn two 2.5" drives into a single bay, replace an optical drive with an additional HDD, or anything like that. What I have in mind is a single 2.5"-form-factor device that houses two independent hard drives, with separate housings (likely) and distinct controllers. Probably all they'd need to share is the power & SATA connections. Probably no such thing exists, but because I know there exist hard drives the physical size of a stack of postage stamps (roughly), I have to ask.

• Get extra hard drive space from windows 7

  - by abhinole

  I am using Ubuntu 12.04 and Windows 7 (dual-boot) on my laptop.For some reasons I want some more space in my Ubuntu partition.I have installed gParted in Ubuntu.Now is it recommended to get this required extra space from Windows 7 drive (*where my linux is installed *) directly using gParted? Will it cause damage to my boot loader or my data on the partition from where I wish to grab some space? Any help will be appreciated. Thanks in advance.

• Fresh Vista install and the strange appearance of boxes/rectangles

  - by Nick

  I purchased a new hard-drive, and after doing a fresh install of Vista and installing all updates/latest drivers, I'm noticing that all of a sudden and shortly after being powered on, I get black boxes/rectangles all over my screen (below). Any ideas as to what could be causing this? On a (maybe) related note, my brand new hard-drive is squeaking. Not often, but it is there. Debating on whether or not it is worth the hassle of sending it back, or if this is related to the mysterious rectangles.

• Windows shows incorrect free space on Raid 10 volume

  - by Adenverd

  I have 4 1TB hard drives in RAID 1+0 configuration. Theoretically, I should have ~2TB of available space. Windows says the drive has a total size of 1.81 TB, which I'm fine with. As far as files on the volume go, I used WinDirStat to determine that I have 552.8GB of files on the volume. This means that I should have somewhere around 1.3TB minimum of free space. Yet Windows shows the drive as only having 492GB of free space. Are there hidden files somewhere that I can't see (I have show hidden files/folders turned on)? Does Windows not recognize that old files have been deleted? Is there any way to correct this problem?
