• My (C:) drive changed from Basic to Dynamic, is this bad?

  - by bbman225

  I'm really worried here. My computer still runs, so I take this as a good sign, however let me explain my situation: I am trying to install Ubuntu Linux, and the installer was having problems, so I went back into the partitioning tool on my Windows 7 (after having successfully shrunken my C drive and created 55 GB unallocated space) and I attempted to create a new partition out of the 55 GB and make it a simple NTFS drive so that I could let the installer wipe it clean again and format it in whatever file system it prefers. Now, after googling it and running through the process I noticed that all of my drives, including the C drive and the one I just made changed from type "Basic" to type "Dynamic." What is a dynamic drive and should I be worried?

• Why does unpartitioned Hitachi HDS5C3020 drive start consuming 50% more power 15 minutes after boot?

  - by Pro Backup

  In a Debian 6.0.6 system there are 74 pieces of 2TB Toshiba DT01ABA200 drives. These drives are identified as Hitachi HDS5C3020BLE630 drives running firmware revision MZ4OAAB0. 64 Drives attached via HP SAS expander cards to an LSI 2008 SAS controller, another 5 drives are connected directly to the mainboard, 4 drives are connected to a Sil based PCI controller and last 1 drive is only powered and has no data cable connected. The controller LSI and Sil card's their onboard BIOS are both disabled and the mpt2sas and sata_sil modules are removed from the Linux debian 2.6.32-5-amd64 #1 SMP Sun Sep 23 10:07:46 UTC 2012 x86_64 GNU/Linux kernel. The mpt2sas module is loaded after boot using a modprobe command in /etc/rc.local. These 74 drives are not partitioned, neither formatted and also not mounted. The system consumes: with 0 drives: 70.6 - 70.9 Watt (also 15 minutes after boot); with 74 drives: 330 - 360 Watt, just after boot (is equivalent to 3.5 - 3.9W per drive in idle state); with 74 drives: 420 - 466 Watt, each time in the 15th minute of uptime (is equivalent to 4.7 - 5.3W per drive in idle state). The drive specification lists 4.7W as read/write, and 3.3W as idle power consumption. The increased power consumption is most likely on the 5V line, because after roughly 1 minute an "over current protection" (OCP) of the power supply (PSU) shuts down the power. The used PSU is a single rail model with an OCP of 122A on the 12V line and 55A on the 5V line. Regression: It doesn't matter whether the drive its APM value is set to disabled or 1 (maximum power saving). The operating system records no read/write activity in /proc/diskstats. The values there are identical (28 read, 0 write operations) as immediately after the modprobe operation. Can't test what happens when booting into the mainboard it's BIOS - to exclude any OS intervention - because the Super Micro X8SI6-F mainboard running firmware 06/27/12 has a bug that incorrectly reads a +74.0 C CPU sensor temperature as "High" in BIOS mode, and shuts down the power after 1 minute. What might be causing the drive read/write activity on all drives in the 15th minute after boot and how to prevent it from happening?

• EEE PC 701/4G Surf Internal Drive: Is it really SSD?

  - by Bart Silverstrim

  I have an old EEE PC with the 4 Gig internal drive. Everything I've read keeps saying it's an SSD drive; running lshw tells me that it's an ATA disk, Silicon Motion SM. The thing seems to be rather slow, though. I know it has a 900 Mhz Celeron processor and only 512 meg of RAM, but it seems like drive access is slow even for those specs. Does anyone know if it really has an SSD drive? I thought that compared to regular hard disks SSD's were blazing fast, and this feels like and acts like it's pulling from something more akin to an internal USB memory stick.

• Will Windows XP work on a Hybrid Hard Drive?

  - by Ben Torell

  I'm looking into getting the Seagate Momentus XT hybrid hard drive, and I'm planning on dual booting between Windows 7 and Windows XP. I know 7 and Vista have native support for taking advantage of the SSD portion of a hybrid drive, and I assume XP does not have any such support, but will XP still work on the drive? I would think it will, but I wanted to be sure, and the Googles are coming up empty for me on this one. Thanks!

• Real performance gain from faster IDE or SATA hard drive?

  - by raw_noob

  How much of a real-world performance gain would you expect from: replacing a 5400rpm IDE HD with a 7200rpm IDE HD? replacing a 5400rpm IDE HD with a SATA-150? It's assumed that the drive in question is both the system drive and the only drive. A modest AMD Sempron-based home computer with adequate DDR memory running Windows XP Home SP3. Thanks for looking.

• How do I turn a shared computer back into a shared media drive?

  - by Brian Green

  There is an external hard drive that is set up as a shared media device for a TV. I tried to hook up my the library on my desktop as a shared media drive to watch movies from my computer on the TV. It worked for a little bit but about 5 seconds after getting into my computer the tv went blank and I couldn't access the external hard drive any more. When I checked on my computer the Hard drive was no longer a shared media device but now it was a computer on the network. How do I fix this and turn it back into a shared media device so I can access it on the TV?

• Why is writing to my external hard drive slow, while benchmarks show fast writing?

  - by matix2267

  I have an iOmega eGo 320GB portable drive connected through USB2.0 to my laptop running Windows Vista. It's been working fine for quite some time until recently it became very slow when writing e.g. when copying ~300MB movie over to the drive at first it is extremely fast but it actually doesn't write it only puts in cache and then hangs on last 10-20MBs for about a minute. When copying larger files it's the same story: starts fast but then slows down to ~5MB/s (sometimes even slower down to 2MB/s). Strange thing is that I have always had caching disabled for this drive (it was disabled by default and I never bothered changing it). At first I thought that the disk is dying so I checked S.M.A.R.T. values and everything is fine there. I also run chkdsk and it seemed to fix the problem - it worked fast for a few minutes but then it slowed down again. I also tried plugging it into another USB port - no difference. Additionally I noticed that reading under certain circumstances is sometimes slower e.g. loading times for some games are ~10 times longer, whereas simple copying files from this drive to my internal HDD is fast. I ran a speed benchmark using CrystalDiskMark with a 5x100MB run and strangely got these results: read write (MB/s) Seq 33.05 28.25 512k 17.30 15.27 4k 0.267 0.372 4kQD32 0.510 0.260 This is different from what most other people have (I've found many threads about slow disk write while googling but all of them were slow on benchmarks too) which is why I decided to post this problem here. BTW most of the time when writing (or sometimes reading) the activity led is mostly idle (blinks a while and then stops for longer, sometimes has slower blinks ~1 sek, sometimes goes off for a few seconds - extremely long blink :) ) but when benchmarking, defragmenting or just reading (copying from this drive, installing apps from installers there, watching HD videos) it is blinking really fast (like it should) and there are no slowdowns. It shouldn't be driver issue unless stock Windows drivers have some issues I'm not aware of.

• Is a computer's DRAM size not as important once we get a Solid State Drive?

  - by Jian Lin

  I am thinking of getting a Dell X11 netbook, and it can go up to 8GB of DRAM, together with a 256GB Solid State Drive. So in that case, it can handle quite a bit of Virtual PC running Linux, and Win XP, etc. But is the 8GB of RAM not so important any more? Won't 2GB or 4GB be quite good if a Solid State Drive is used? I think the most worrying thing is that the memory is not enough and the less often used data is swapped to the pagefile on hard disk and it will become really slow, but with an SSD drive, the problem is a lot less of a concern? Is there a comparison as to, if DRAM speed is n, then SSD drive speed is how many n and hard disk speed is how many n just as a ball park comparison?

• if a usb pen drive has 64349 cylinders, is it damaged?

  - by Andrew S

  I have a 4Gb USB pen drive that I'm trying to format with FAT32. When I run fdisk, it gives me this message: The number of cylinders for this disk is set to 64349. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) I've tried deleting the partition table, creating new partitions, etc, but they never work. Sometimes I can write to the drive the first time I use it after formatting it, but then it becomes read-only in both Windows and Linux. I've tried this on multiple computers. Am I doing something wrong, or is the drive reporting an incorrect number of cylinders? Is the drive itself likely to be corrupted, and is there anyway to fix this under Windows Vista or Linux? Thanks

• What's a fast way to copy a lot of files from an internal hard-drive to external (USB) storage?

  - by jonathanconway

  I have a large amount of data - about 500 GB - on the internal hard drive of a desktop PC. This includes music, videos, PDFs... you name it. I want to copy everything to an external USB hard drive (1.5 tb capacity). The desktop PC runs Ubuntu. To being with, I simply plugged in and mounted the hard drive and dragged the top-level folder onto the drive. It's started copying, but it seems to be proceeding very slowly. About 10 minutes later and it's only done about 500 MB. I'm sure this is slower than what I could achieve with less total data. So I'm wondering if there's a quicker way of doing this. Would it be better to copy it in portions of 500MB or so, rather than all at once?

• Mac failing (failed?) hard drive - is all hope lost?

  - by Daniel

  It's a 500 GB Seagate laptop hard drive that came with my Macbook Pro. Apple partition format. Already replaced and now have it external, connected via SATA/USB adapter. Trying to get just a few files that I worked on while out of town when it crashed (and thus did not have my time machine backup drive). Drive will not mount, but OS X Disk Utility detects it and can read the capacity, model number, and even the name of the partition, which leads me to believe all hope may not be lost. Failed attempts so far: Disk Utility verify+repair says drive cannot be repaired and that I should back up immediately (lovely) Disk Warrior says it cannot rebuild the directory due to hardware failure Data Rescue quick & deep scans immediately failed PhotoRec says "error reading sector" for every sector (at least for the few minutes I let it run before closing it to explore other options) What else can I try here? Again, I'm just looking for a few, small files (python scripts to be specific) - not a full recovery.

• What could be wrong with my CD drive and how do you fix it?

  - by Jamie

  My CD drive hasn't worked in about 8 months. I was burning CDs in a hurry and pulled it out because it was taking too long (probably an average amount of time). Im running a laptop (Toshiba Satellite A505-6965) that uses a slot drive. Now my computer doesn't accept CDs. It used to pull them in but it doesn't anymore. Ive heard it make odd noises a few times but thats it. The slot is these spongey things and Ive managed to peek into the drive with a flashlight and theres nothing in the way, really. Could someone explain the mechanics of what happened and if it would be possible to fix it? If itd be possible to fix it through Linux that would be great since I keep getting the BSOD (0x0000007B) and am going to try reinstalling Windows 7. But I can't really do that since I don't have a USB drive larger than 2 GB (Windows is about 4 GB) so Im relying on Linux ATM.

• Make a drive from one machine appear as a physical disk in another machine.

  - by Roberto Sebestyen

  I want to take a physical disk (or part of a disk) in one machine (call it machine-A) and I want to make it available in another machine (machine-B). But I don't want to map a network drive. I want it to appear in machine-B as a physical drive. Even though it is not a physical drive. The reason I want to do this is i want the ability to create shares in machine-B on that drive. Since I cannot do that on mapped drives, I need to use some utility that fools machine-B to think that it is a physical drive, and treat it as such. Both of these machines are windows server 2003. I heard about NFS, It sounds like what could be the solution to my problem. But isn't that a Linux/Unix protocol? What tools can I use to make this happen? Are there any open source solutions? I don't care what the solution is, as long as it achieves the end result, preferably open source solution though. Thanks for reading guys and gals!

• Viruses on external hard drive -- how to clean files?

  - by Jade

  Last year my Dell laptop caught some pretty nasty viruses; I saved all my important stuff on an external hard drive. In an unrelated turn of events, I replaced my Dell with a Mac and have been able to retrieve data from the hard drive without trouble. The problem is, I'm sure the hard drive has a few lingering viruses and I really don't want to infect any more PCs with it. I was planning to reformat it anyway, but I'd like to be able to save my files. Would transferring those files to my Mac and then scanning them for Windows viruses before throwing them back onto the newly reformatted hard drive be enough?

• Transfer hard-drive with windows XP to another computer. On booting, asks to activate xp

  - by Jesse

  I had an old computer sitting around that I have not been able to boot successfully. I moved the hard drive and placed it in my newer computer. If I boot linux, I can mount the XP hard-drive and access the files. If I try to boot from the XP hard-drive, it will boot, but it asks me to activate windows before proceeding. If I continue, I get the "activation window" with two images/icons(?) which are failing to load. Nothing else happens. The version of windows came with the original computer the hard-drive came from, so I'm not sure if I'm married to the broken computer (I hope not!). Is there anything I can do in order to boot into XP from the new computer?

• What's the best tool to use to automatically backup selected folders from Windows to my external hard drive?

  - by PhD

  I have a 1TB external hard drive and I'd like to periodically schedule backups of my "Libraries" in Windows to the external drive. I'd prefer if it could detect what files have changed and periodically transfer them to the drive instead of I having to do it manually. Is there a way in Windows 7 to do this automatically? If not, what are some external tools (preferably free) that I can use for this? EDIT: I've used Windows back-up and I find it restrictive for detecting changes and backing up automatically. That's all that I'm aware of. My WD hard drive had something for this but the application doesn't work any more and it wasn't that good either. So, I wish to know what are my options.

• Could replacing an old hard drive's circuit board make it work again?

  - by oscilatingcretin

  I have a 12-year-old, 10gb Maxtor drive that died on me around 7 years ago, but I have not had the heart to throw it away. When the computer powers on, it whirrs silently as it tries to spin up and then it stops. So, a few years ago, I sent it off for professional data recovery. They were able to retrieve quite a bit from it, but I know there's a bunch more there. It only cost $700, so I just chalked up the lackluster recovery effort to "you get what you pay for" considering that most companies will charge you several thousands of dollars for this kind of data recovery. When they sent the drive back, I couldn't help but plug it back in just to see if maybe they unjammed something in the process of disassembling/reassembling the drive. To my surprise, the drive had a much healthier spin-up sound and actually stayed spinning for several minutes before winding down to a halt. Windows is even able to detect and interact with the drive, but I get I/O errors after so many minutes of waiting for it to mount. Before I start doing stupid stuff with it like dropping it on the ground, freezing it, crapping on it, etc, I decided to buy the exact same model off Ebay so that I could swap the circuit boards as a last-ditch effort. While it's en route, I thought I'd come here to ask if this is even a worthwhile effort and, if even remotely so, what should I know before ripping off the old board and slapping on the new?

• Make the recycle bin of the SSD on a RAID0 drive?

  - by Rolnik

  I don't know about you folks, but I hate the idea of junk sitting on my tiny 30GB SSD. Any way to designate another drive to be the host of the Recycle Bin for items formerly on the SSD? Basically, I need to know how to make a lower-priority drive receive the recycled materials from the 'main' drive, which happens to be short on space. The best thing I can think of is a batch file that a) syncs 'recycle' to another drive; and b) empties the recycle bin. ... but that's too much work for me.

• Windows 7 not detecting external hard drive but Ubuntu is detecting. Why?

  - by unlimit

  I have a 500 GB Toshiba external hard drive. Since yesterday Windows 7 stopped detecting it, however I do see it listed on the "Safely remove hardware and eject media" icon on the taskbar. Then I tried the same external hard drive on my Ubuntu and it detected it just fine. Ubuntu and Windows 7 are on the same laptop. I have dual boot. Can someone tell me why is it happening? Am I missing a driver in Windows 7? Additional info: This drive has worked perfectly fine in the past. I did not format this drive ever. It just stopped working yesterday in windows.

• Trying to format drive fails

  - by david

  since I will be doing an internship for which i need to use Windows software, I have decided to ruin my day trying to remove my Ubuntu 12.04, install Win XP SP3 (since the DualBoot theme from ubuntu suggests to first install Windows and then Ubuntu, for problems with the bootloader if you do it the other way around) and then reinstall Ubuntu 12.04 since I would like to keep using it as my primary operating system, using WinXP exclusively for the internship. Other than that, I would like to have a partition for the data, which can be used by both Ubuntu and Windows. So now, I have used the disk utility run from an ubuntu-live cd to format my drive with Master Boot Record (being conscious of the fact that this way I will lose all my data, which I have saved on an external drive before, and that my Ubuntu won't work anymore afterwards), creating partitions for Windows (NTFS), personal data (FAT, since as far as I know both Ubuntu and Windows can deal with this), a Swap partition for Linux, and one partition for Ubuntu (ext4); trying to install Win XP from cd gives me a blue screen, which stops the setup and telling me to remove all recently installed drives and to run CHKDSK. So I thought, that maybe Windows doesn't like pre-partitioned drives for its installation and thus I need to re-format my hard drive in order to have a completely "new" drive, which I can then, during the Windows-installation, partition in order to create the partitions I need. Trying to do this, though, the disk-utility run from the live-CD gives me this warning: Error creating partition table: helper exited with exit code 1: In part_create_partition_table: device_file=/dev/sda, scheme=0 got it got disk committed to disk BLKRRPART ioctl failed for /dev/sda: Device or resource busy I do not understand why it tells me that the hard-drive is busy, because, as stated above, I am doing all this from a live-CD. Thus, my questions are: How can I resolve the error given by the disk utility? Does it make sense to use four partitions in the way mentioned above? And if not so, which partitions should I create? Can I, theoretically, partition my drive from an Ubuntu live-cd in order to create the partitions I want and to install first Windows and then Ubuntu? Thanks for any help, David

• External USB Drive

  - by ErocM

  I have a server that I hooked up an external USB drive. It was formatted in windows and has files on it already. I'm new to Ubuntu so please be patient...

• Lubuntu Full Install on USB Drive with Full Disk Encryption and Grub2

  - by vivi

  I apologise for the wall of text, but I want you to scrutinize my thought-process to make sure there's no mistakes and no other way around it: I wish to have a full install of lubuntu with full disk encryption on one of my usb drives. The laptop I would be booting it from also has windows 7. I want to maintain that OS. From what I've read I must place grub2 on the usb drive so that: If I have the usb plugged in, the laptop would start lubuntu (having USB HD in the BIOS Boot options) If I don't have the usb plugged in, it would normally start windows 7. That's exactly what I want it to do. But: If I install from the normal .iso: Clicking "install lubuntu alongside them" would install it onto my normal HD. Clicking "Erase disk and install lunbuntu" would delete all the stuff I have in my HD and install lubuntu on it. Clicking "Something else" would allow me to choose to install lunbuntu and grub2 onto the usb drive, but would not provide it with encryption. So the normal .iso won't work for what I want. Then I found the alternate .iso and this tutorial: It allows me to install lubuntu with all the options I want and gives me the option to choose where to place the grub2! Hopefully there are no flaws in my train of thought. If there aren't, I have a few questions regarding that tutorial: The author says in his case choosing "Yes to install GRUB to your MBR" installed the grub to the usb drive's mbr. I can't have "in his case". I need to be sure that's what it will do, so that it doesn't mess up the windows boot loader. Choosing "no" would open this window and allow to choose where I want to install the grub. Unfortunately I don't understand which option I should type in the box to install it into the usb drive. Would removing my laptop's Hard Drive ensure that the grub is installed onto the usb drive if i picked first option, "yes"? I apologise once again for the wall of text and appreciate any help you guys can offer me.
