• Deleting Time Machine in Mac OS X 10.6.4

  - by cappuccino

  Does anyone know how to delete Time Machine in Mac OS X 10.6.4? Before answering: sudo rm -rf /whateverthetimemachineis does not work Disabling the ACL permissions first with sudo fsaclctl -p /whatever -d does not work, sudo: fsaclctl: command not found Use the delete all backup feature in Time Machine... this is slow as hell, would take days. Need a command line solution. No I don't want to reformat the drive, I have other content on it, and no don't say I should have separated on two partition or two drives, I did it this say since partitions cannot be dynamically changed, and two drives is annoying since, whats the point of having a big drive?... plus has no relation to the issue at hand. Already googlied for hours and read everything on Super User, nothing working. and all solutions are the first 4. Any clues?

• RAID1: Migrate HDD to SSD?

  - by OMG Ponies

  My current workstation uses an Adaptec 5805, with Win2008 mirrored between two 72 GB (10K?) savvio drives. My question is if there's a way to migrate the mirror to use SSDs - I've been looking at 90GB Corsair Force (Sandy Bridge) to replace the existing setup. If it's possible, without installing the OS fresh. If I replaced the mirrored drive with an SSD, would the array sync the drives? Then I could promote the SSD mirror to be the primary, and use the second SSD as the mirror. That'd be too easy... Or should use Ghost to get an image of the existing setup, apply it to the SSD for a new mirror to be setup on?

• How should I use my new SSD drive?

  - by jasondavis

  I just built a new PC the other day. Specs... Processor: Intel i7-930 quad core CPU CPU Cooler: COOLER MASTER Hyper 212 Motherboard: AsRock X58 Extreme 3 RAM/Memory: 6gb G-Skill tripple channel DDR3 memory (3 sticks of 2gb planning to get another kit to make it 12gb total soon) Operating System Hard drive: Intel X25-M 80GB Mainstream SATA2 Solid State Drive Video Cards: 2 XFX ATI Redeon HD 4650 cards to run 3-4 monitors Case: Lian Li PC-B10 Midtower case Power Supply: Antec TruePower New TP-750 Blue 750W Operating System Windows 7 Pro 64bit Not sure if the specs are helpful at all but I posted them just in case. So I got everything put together and running great so far but I need some advice/ideas/help/tips. I got the SSD drive in hopes of using it strictly for my windows 7 install along with all my other programs I install. I am then going to get another drive or 2 just for data (video,music,photos, etc). So my plan is to just install the new data drives and then in windows 7 I will change my "My documents" "My Music" "My Video" "MY Photos" library's to be located on the data drives instead of the OS SSD drive. I would ultimately like to install all my programs with my windows install on the SSD drive and then create an IMAGE of the drive and then 6 months down the road if things are sluggish I can just wipe the drive and restore my IMAGE with all my programs and settings in tact still. So here are some questions now. 1) How can I verify that TRIM is working on my new SSD? 2) Is there anything above that I missed that I should be doing? I think I once read that there is a page file or some sort of file that windows changes a lot and that it should be moved off f an SSD an onto my data drives. DOes anyone know what I might of heard? If you do can you explain the pros and cons of doing such a thing as well as how to possibly? 3) Any tips or advice to get the best performance from all this, I built a pretty nice system and I just want to make it stay that way as long as I can.

• Internet Explorer defaults to 64-bit version

  - by Tim Long

  My IE8 has suddenly started defaulting to the 64-bit version. I have no idea how or why this has happened, but I suspect it might be linked to the Browser Choice Screen that Microsoft was recently forced to display by EU law. However, many web sites will not display correctly in IE8 x64 (eg. sites that use Adobe Flash or Microsoft Silverlight). I have the 32-bit version of IE pinned to my taskbar and if I launch it manually, everything is fine. But when I click on a URL from another program and IE is not already running, then the 64-bit version gets launched. This really messes with programs like BBC iPlayer which rely heavily on Adbobe Air and Flash. So, how do I get IE8 32-bit version to be the default version again? I've tried using the "default programs" control panel and that doesn;t make any difference (in fact, it doesn't give the choice between x84 and x64 versions, it just lists "internet explorer").

• Storage setup for large files

  - by Mecca

  I need to store over 200TB of data (all types, biggest being video files) and be able to access it over a local network. The files will be accessed for editing or searches. I don't need versioning, but a setup that would keep me safe from harddrive failures would be nice. Right now the content is on different harddrives, some external drives, some regular. I don't exclude the possibility of buying new/extra drives if necessary. If they will ever be exposed to the web, it wont be to the public, but just a couple of people. I have no idea what to buy to make this happen. I see some NAS solutions over the internet like this http://www.bestbuy.com/site/a/2266043.p?id=1218317764591&skuId=2266043 but the storage is not enough, plus it doesn't seem to be scalable. What do you recommend? Thanks

• mirroring linux server to external usb harddrive

  - by DuPie

  My google-fu must be sucking. i havent been able to find a good solution for the following: numerous Linux server on commodity hardware Trying to do a recovery mirror copy to external harddrives External harddrives are smaller than source harddrives, but larger than data External drives are connected via usb2 (slow) Servers range from 20GB of data to 400GB of data Servers are remote, so hands on access is a pain need to copy boot files. empty external drives currently Basicly, looking for a way to do use a ghosting solution from INSIDE a running linux server to an external harddrive, without booting a cd etc. the rsync/cpio solutions i've looked at dont work great with grub/dev/proc etc. I understand that since the system isnt offline, it wont be a "mirror" image as files change, but thats ok. Are there any free/commercial products that would work?

• Would hybrid drive work after SSD failure

  - by lulalala

  Hybrid hard drive combines SSD with traditional hard drives. I know that SSD can fail much often than traditional hard drives. So I want to ask that, when the SSD part of the hybrid drive fails, would I still be able to use the traditional hard drive? If it won't work like that, then I will consider add-in SATA cards instead, as it delegates risk much better. EDIT: I guess it differs from model to model, so if yes what models would work. (I am evaluating Seagate DX for now)

• Inexpensive degaussers or HDD shredders?

  - by Nicholas Knight

  I do a lot of work for a small cash-strapped business that has a lot of active hard drives, most are consumer-grade SATA of about five years of age, and predictably they are dying at an increasing rate, and a lot of the time they can't even be detected, let alone complete a zero-out cycle. Right now those drives are just being stored, but that can't continue forever. We've got a couple bad LTO tapes it'd be nice to deal with, too. There are very real security and legal issues that make dropping them off with someone who claims they'll be properly destroyed a gamble. I've looked around at degaussers and HDD shredders, and the ones that don't look like they come from some guy in his basement all seem to be $3000+, which is hard to swallow right now. Is there anything out there in the $500-1500 range that you would recommend? (Speed isn't a big issue, if it takes several minutes or even hours per drive, that's completely OK, we've only got 10 or so thus far.)

• Raid on ICH9R chip set

  - by user500982

  Hi Im looking at buyign this MB: http://www.supermicro.com/products/motherboard/ATOM/ICH9/X7SPE-HF-D525.cfm Im wondering though if the chipset will support the raid configuration I need. Im looking to configure the following arrays: raid array 1: 2 2TB Disks in Raid 0 raid array 2: 2 2TB Disks in Raid 0 raid array 3 (not actualy an array): 1 300GB Disk not in raid, to be used for OS and boot. So in total there would be 5 drives and the board supports 6. so im good when it comes to connections. However I have herd some chip sets only support one raid array (volume). so either all drives are individual, or are in the array. I must have 2 sperate raid arrays independent of each other, and a 5th drive not in any array. Anybody know if this setup will work? Thanks, -Stewart

• Can I get redundancy with a JBOD storage subsystem

  - by Dat Chu

  I have a Promise Technology J610S. This is a JBOD subsystem. Is it possible for me to buy a SAS hardware RAID controller and provide some type of redundancy for these drives? I am unsure whether I will use Linux or Windows yet so an answer with enumeration for both would be highly appreciated. One solution that I thought of was: if my J610s can export each drive as a target, my server will simply see 16 drives. The RAID controller can then perform the RAID5/RAID6 if I want.

• Optimal Disk Setup for OLTP SQL Server

  - by Chris

  We have a high transaction (lots of reads and writes) database server (running SQL 2005) that is currently set up with a RAID 1 OS partition (C:) and a RAID 5 data/log/tempdb partition (D:). The C: has 2 drives and the D: has 4 drives. The server has around 300 databases ranging from 10MB to 2GB in size. I have been reading up on best practices for partioning the disks, but would like some opinions on our setup since we are so limited in the number of disks. It seems like RAID 10 is popular, but I dont think we could use it with only 6 total disks to work with. Thanks. Update I went with 3 RAID 1 Partitions (2 disks each) Partition 1: OS, TempDB, Backups Partition 2: Logs Partition 3: Data

It's not my first time installing it, but it's the first time having two annoying problems: 1) Randomly, the system clock changes time all by itself - to fix it I have to open the time window and sync it with the internet. 2) Randomly, internet connection stops working - to fix I have to run troubleshooting. Windows will find a problem with IP on the "Ethernet" connection and fix it. 3) In rare occasions, my PC freezes and I need to restart it (a BSOD once happened, but after that only freezes) How can I permanently solve these problems? This is what I've already tried: Reset Virus scan Stop/reset the Windows Time service Disable/re-enable Windows Time automatic internet sync Change time from BIOS Change motherboard battery

• Windows 7 - Home Drive Map Fails

  - by Ed Fries

  Server 2003 SP2 (not R2) with 2 new Win 7 Pro workstations. Home Drive is set in AD (not GP) to map to \\server\users\username. Home Drive map fails, other network drives map correctly. No error logged on server or PC, Win 7 shows "Could not reconnect all network drives." There is no Y: (Home Drive) listed, either in the GUI or via Net Use. Manual map via batch file in startup group with the same path works correctly? Home Drive map works correctly on XP workstations.

• When is it time to buy a new hard drive, and what considerations go into buying a new hard drive?

  - by user1125620

  I've had my current hard drive for about 4-5 years now, and I've never had a problem with it before, but now it's making whirring noises. It's done this before and, last time, the noise did go away the next day, but I have accumulated quite a bit of information that I wouldn't want to lose on the drive. HD Tune Pro and Berlac Advisor both said the drive was healthy, and I wouldn't want to get a new one unless it was absolutely necessary or was going to show drastic performance improvements. My only knock against the drive would be that Visual Studio takes longer to load than I'd like it to. HD Tune Pro says the average read speed is 54.3MB/s. I'm not sure if that's good or bad, but it seems about average compared to similar drives on http://www.hdtune.com/testresults.html. Model #: WDC WD5000AAJS-22YFA0 So, should hard drives be replaced after a certain amount of time? Has mine reached that point? Would a new hard drive be any faster?

• Wrong chrome full screen resolution with multiple displays

  - by Martin

  I am using Google Chrome on Windows 7 64bit with two displays. The displays have different resolutions and aspect-ratios. My problem is best visible when playing back full-screen videos from a flash player inside chrome (but it is not flash related). The maximum size is calculated from the primary displays' resolution, even when the relevant window is maximised on the second screen. The problem is also visible on websites that set the width to 100%. The 100% then apply to the primary display, even when the window is opened on the secondary display. Are there any known solutions to this problem? I am observing it since many Chrome versions, do not know if it has been ever correct.

• eTrayz: Replace base system with a bootstrapped Debian

  - by knoopx

  I bought an eTrayz NAS time ago. The device is more or less good but it ships with a closed-source custom linux and a bunch of broken web-apps. I wanted to replace the whole system with a raw Debian installation. I successfully bootstrapped a Lenny Debian into a chroot and I'm able to use use it. However I would like it to be the default system and to boot automatically at login. The device itself ships with a bundled 2.6.24.4 kernel. I think the kernel is on a dedicated flash memory so I would prefere not to re-flash it. What do you think is the best way to accomplish it?

• Expanding RAID 1 array size (Adaptec 1420SA controller)

  - by cincura.net

  I have an Adaptec 1420SA controller in server and RAID 1 array created. The old disks slowly started to report S.M.A.R.T errors so I replaced first one, rebuild array and then other one and rebuild the array again. But the new drives are bigger, so I'd like to expand the array to use full disk capacity. Is it somehow possible? In the Adaptec configuration utility, after POST, I didn't found anything that could do it. I still have the old drives, if it helps. The array is used for system (Windows 2008 R2 SP1) booting. Thanks.

• How do I execute a script or program on Windows Shut Down

  - by Subhen

  I want to run a exe or bat file when window shut down? I want to unmount few drives , which are mounted by my application , when user shutdown the system. For that I need to execute another exe on shutdown, which will disconnect drives mounted by my app. I got few links which shows we can create a entry in Group Policy to execute a programe while window shut down. I am not sure how I can add a entry to Group ploicy by C++ code. Again , group policy doesn't work with Win Vista. Any other better approach ?

• Rebuilding RAID1 in Ubuntu

  - by John Utech

  I had my second HD in my RAID1 come up with bad sectors. So I got another drive and pulled out the bad sector drive and put the new drive in. With the original working RAID1 drive in the computer it failed to boot. I manually copied everything from the old drive over via a Gparted Live CD. Still no booting. Kind of scratching my head here as I can see that both of the drives have data on them but are unable to get either of them to boot. I used a Ubuntu live CD and couldn't even manually mount either of the drives, which I thought was really the odd part. Not sure where to go from here.

• misaligned raid partition in Ubuntu 10.04

  - by Linux Jedi

  I attached two identical hard drives to my linux machine. Then using gparted I formated the first 1024 mb at the beginning of each drive as linux swap space. Then I went into system-administration-disk utility. In there I went to file-create-RAID array. I selected the remaining space in each of the two identical hard drives and created a striped raid array. After the array was created, a warning message appeared. It said "The partition is misaligned by 522240 bytes. This may result in very poor performance. Repartitioning is suggested." What do I do now? As far as I can tell, the partitions are identical.

• ZFS Recover from Faulted Pool State

  - by nickv2002

  I have a six disk ZFS raidz1 pool and had a recent failure requiring a disk replacement. No problem normally, but this time my server hardware died before I could do the replacement (but after and unrelated to the drive failure as far as I can tell). I was able to get another machine from a friend to rebuild the system, but in the process of moving my drives over I had to swap their cables around a bunch until I got the right configuration where the remaining 5 good disks were seen as online. This process seems to have generated some checksum errors for the pool/raidz. I have the 5 remaining drives set up now and a good drive installed and ready to take the place of the drive that died. However, since my pool state is FAULTED I'm unable to do the replacement. root@zfs:~# zpool replace tank 1298243857915644462 /dev/sdb cannot open 'tank': pool is unavailable Is there any way to recover from this error? I would think that having 5 of the 6 drives online would be enough to rebuild the right data, but that doesn't seem to be enough now. Here's the status log of my pool: root@zfs:~# zpool status tank pool: tank state: FAULTED status: One or more devices could not be used because the label is missing or invalid. There are insufficient replicas for the pool to continue functioning. action: Destroy and re-create the pool from a backup source. see: http://zfsonlinux.org/msg/ZFS-8000-5E scan: none requested config: NAME STATE READ WRITE CKSUM tank FAULTED 0 0 1 corrupted data raidz1-0 ONLINE 0 0 8 sdd ONLINE 0 0 0 sdf ONLINE 0 0 0 sdh ONLINE 0 0 0 1298243857915644462 UNAVAIL 0 0 0 was /dev/sdb1 sde ONLINE 0 0 0 sdg ONLINE 0 0 0 Update (10/31): I tried to export and re-import the array a few times over the past week and wasn't successful. First I tried: zpool import -f -R /tank -N -o readonly=on -F tank That produced this error immediately: cannot import 'tank': I/O error Destroy and re-create the pool from a backup source. I added the '-X' option to the above command to try to make it check the transaction log. I let that run for about 48 hours before giving up because it had completely locked up my machine (I was unable to log in locally or via the network). Now I'm trying a simple zpool import tank command and that seems to run for a while with no output. I'll leave it running overnight to see if it outputs anything.

• Does Apache 2.2 (windows) have any default bandwidth limit?

  - by igino manfre'

  I'm running Apache on a server in cloud (Windows server 2008 R2 on VMware, 1 Gbps of BW, http://95.110.164.61 ). I'm streaming many live DVB MPEG Transport Stream, precompressed in loop, (not flash) generated by VLC on port 640xx and then reverse proxied by Apache on port 80. The server's firewall is open for VLC and Apache on all ports. Above 1.5 Mbps the reproduction is affected by continous stop & go. Please note that if you request a stream generated by VLC directly at http://95.110.164.61:64087/mpg2_6.4 you see a correct stream, while if you request http://95.110.164.61/mpg2_6.4 you do not. I know that Flash streaming Server uses Apache to stream on port 80 (and it works). I'm not an expert with Apache, can anyone tell me if any "special" module is required to increase the bandwidth?

• FreeBSD after motherboard replacement; should I have any concerns?

  - by cc

  So after three years my motherboard (Asus M2N-0MX) has died off. As I go shopping for i's replacement tomorrow I have a concern about the data that I currently have on the drives wtihin. I'm currently running BSD 6.2, and am wondering if there would be any concern with installing a new OS on that system, would it be better to jsut install the latest BSD version, and are their any pitfalls that I should watch for to make sure I don't end up losing 750gb's of data. The setup consists of the following(to the best of my knowledge): Pioneer DVD drive 3ware RAID card four 250gb SATA drives in RAID 5 config thanks to anyone that can offer some advice, or just to confirm if I am over thinking things.
