  • win8: access denied to external USB disk; update access rights fails

    - by Gerard
    I use to work with 2 laptops (vista and win7), my work being files on an external usb disk. My oldest laptop broke down, so I bought a new one. I had no option other than take win8. 1/ I suspect something changed with access rights, as my external disk suffered some "access denied" problem on win8. I was prompted (by win8) somehow to fix the access rights, which I tried to do, getting to the properties - security. This process was very slow and ended up saying "disk is not ready". Additonnally, the usb somehow was not recognized anymore. 2/ Back to win7, I was warned that my disk needed to be verified, which I did. In this process, some files were lost (most of them i could recover from the folder found00x, but I have some backup anyway). Also, I don't know why, but under win7, all the folder showed with a lock. 3/ Then back again to win8. Same problem : access denied to my disk + no way to change access rights as it gets stuck "disk is not ready". Now I am pretty sure there is some kind of bug or inconsistence in win8 / win7. I did 2/ and 3/ a few times. At some point, I also got an access denied in win7. I could restore access rigths to the disk to "system" (properties - security - EDIT for full control to group "system" ...). But then I still get the same access right pb on win8, and getting stuck in the process to restore full control to "system" -- and "admin" groups. Now, after I tried for more than 3 days, I am losing my patience with that bloody win8 which I did not want to buy but had no choice. I upgraded win8 with the windows updates available. Does not help. Anybody can help me ?

  • Do different operating systems have different read and write speeds?

    - by Ivan
    If I have two different operating systems, such as Windows 8 and Ubuntu, running on the same hardware, will the two operating systems have different read and write speeds? My guess is that there would be minimal difference between operating systems and read and write speeds to the hard disk since the major limited factor is seeking; however, different operating systems may use different file systems in order to attempt to reduce seek time in the hard disk. Likewise, I'm sure that modern operating systems will not actually write directly to the hard disk, and instead will just have it in memory and marked with a dirty bit. Are there any studies that show differences in read and write speeds between OSs? Or would the file system being used by the OS matter more than the OS itself?

  • Fix bad blocks on Mac hard disk

    - by Andrew Vit
    I have a hard disk that I scanned with TechTool and it reports one bad block. As far as I can tell, TechTool only scans and reports a failure. It doesn't fix anything. Back in the day, Norton Disk Doctor did the job of scanning and flagging (remapping) bad blocks on the Mac. Today we have various tools for fixing up HFS+ directory errors (Disk Utility, fsck, DiskWarrior, TechTool), but I don't know of any tool that will do a surface scan and fix the bad blocks too. What software is available for this? If I know the address of the bad block, is there a low-level terminal utility for marking it?

  • HDD vanished after wakeup from standby

    - by Sam
    In my computer I got two hard drives: One 80GB Intel X25 Postville SSD for the system and a 1,5TB Sata HDD for data. When I put the system into standby, and wake it up again, roundabout 50% of the time the 1,5TB HDD is not found. It just vanished from the system (wreaking havok to all programs running which had open files on it). Even going into the system management and refreshing the drives does not find the lost HDD. There are no messages about this in the event log. After a warm reboot the hdd is found again, just like it should. The system is a Shuttle SP35P2 Pro with 8GB Ram and DualCore CPU, OS is Windows 7 Ultimate. I even set up the OS anew, didn't help. Any ideas what might cause this? How to debug, or maybe even fix it?

  • Boot loop that I cannot bypass

    - by lonewaft
    Recently, on a laptop that I've used for a while, I had a strange issue where OS files were corrupted (device manager) and Windows 8 was hung after the login screen, so I reinstalled Windows 7 over the existing Windows 8 installation, and it worked for a couple days. Today, when I tried to use my laptop, it was stuck on a boot loop. Right after the BIOS screen, it would show a flashing underscore, then restart the computer, again and again until I removed the battery. I tried booting to a windows 7 install CD, but the same flashing underscore - reboot sequence happened when I tried. I tried moving the boot priority around (HDD first, CD/DVD first, even USB first) but nothing changed. After about an hour of tinkering with it, I listened to the HDD sounds, and it sounded like the HDD was trying to spin up, but failing (whining noise increasing in frequency that stopped and started in sync with the system restarting). I am planning to replace the HDD, but I'm still confused as to why a faulty HDD would stop the laptop from booting to my install DVD (tried it on a different computer, it booted from that CD fine). Anybody here have any idea why this might be happening?

  • Google Play Music Not Adding MP3s On-Demand

    - by J0e3gan
    My recent attempts to add music on-demand to Google Play Music have yielded nothing - no "Processing music..." or "Added __ of __" messages, just nothing. Previously I could add music on-demand; and nothing has changed on the machine from which I successfully added music previously, from which I have tried to add music on-demand recently. What could be hampering my ability to add music on-demand? WHAT I'VE TRIED: Right after I started using GPM, I briefly found that I could not add music (on-demand), but the problem went away after a logout/login. This time a logout/login has not helped. Dragging & dropping or browsing to folders or files to add has made no difference either. Nor has waiting ridiculously long for GPM to show signs of life after adding music on-demand seemed to work. Digging deeper, I read a related Google Play Help article and followed its suggestions... ran the Google Play Music Manager troubleshooter = no errors or warnings double checked my available storage = 8 GB free double checked supported file types = MP3 is still supported (of course) ..., but the problem remains. UPDATE: I found that if I configure GPM to automatically upload music added to specific folders, it strangely does add automatically what it will not add on-demand.

  • I found two usb sticks on the ground. Now what?

    - by Stefano Borini
    As from subject. I want to see what's inside. I am seriously interested in finding the owner if possible and returning them, but I am worried it could be an attempt at social engineering. I own a macbook intel with OSX 10.6. It is a very important install. What would you do in my situation if you want to see the content without risks ? Any proposal welcome. Edit: I decided not to plug them in, and I brought them to the hotel reception. They will forward it to the police.

  • 1Tb disk formatted on Linux won't mount on windows nor mac

    - by Pedro MC
    I have an external HD (western digital) with 1Tb. I use Linux but I wanted to reserve a cross platform partition on the disk. I decided to create two partitions and used the "disks" application to do it. I created one partition with the LUKS (version 1) encryption and the other one, cross platform, in NTFS filesystem. Things work fine on my OS but when I try to use the disk (the cross platform partition) on both windows and mac the device is not recognized. What could it be? Next, output of "sfdisk -l /dev/sdb": Disk /dev/sdb: 121600 cylinders, 255 heads, 63 sectors/track Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0 Device Boot Start End #cyls #blocks Id System /dev/sdb1 0+ 36473- 36473- 292968750 83 Linux /dev/sdb2 36473+ 121600- 85128- 683789062+ 83 Linux /dev/sdb3 0 - 0 0 0 Empty /dev/sdb4 0 - 0 0 0 Empty

  • Windows boots to Black Screen of Death — Is my HDD faulty?

    - by Flynn1179
    My wife's PC suddenly stopped booting up properly. It gets as far as the Windows 'loading' screen with the bar scrolling away, but that's as far as it gets for some time, then suddenly flashes up a BSoD barely long enough to see, then the display cuts out. We've got identical PCs, and after swapping components, I established that my PC suffers the same problem if I swap in the HDD. Even if I plug hers in as a second HDD on my machine, it still does the same thing, even though it's booting from mine. I can't even boot her machine from CD or DVD either, so I couldn't even use a recovery disc. I did manage to partially boot my PC into safe mode with the other HDD attached, and it got as far as loading 'crcdisk.sys' and froze. Anybody know what could be wrong with it, or at least how I can get the data off the disk? I'm assuming there's still data on the disk, given that it at least shows me the vista 'loading' screen.

  • How can you make a Windows USB HDD Modify All for All Users

    - by David Allan Finch
    Hi, I use a USB HDD a lot between lots of different Windows Boxes. What I find after a while is that there get to be lots of different Permission on the files in some cases stopping me looking at files or removing them. They want Admin rights or even sometimes you need to put the disk back into the original machine with the original user. This is a right pain. Is there away of making the disk have Modify All for All Users and making this the default for all files on the disk. Thanks

  • ext4 filesystem corruption -- maybe hardware error?

    - by pts
    I'm getting these errors in dmesg after about half an hour after I turn on the computer: [ 1355.677957] EXT4-fs error (device sda2): htree_dirblock_to_tree: inode #1318420: (comm updatedb.mlocat) bad entry in directory: directory entry across blocks - block=5251700offset=0(0), inode=1802725748, rec_len=179136, name_len=32 [ 1355.677973] Aborting journal on device sda2-8.

Any obvious ideas what can go wrong in this case? The most reasonable thing I can imagine is that the SSD is silently dropping some write requests, which eventually leads to an EXT4 filesystem inconsistency (but no disk I/O errors). How can this happen? Is there a relevant configuration option I should ensure to be set correctly? What tools should I use to diagnose the hardware failures? Would it be possible to diagnose the SSD failure without overwriting data?

  • Expanding Files 0%, error 0x80070017 Windows 7 x64 RTM

    - by Liam
    I have downloaded Windows 7 x64 from MSDN. I have checked the hash of the file and it is correct. I have them made a bootble USB stick (http://kmwoley.com/blog/?p=345 (had to use my vista bootsect.exe as running 32bit at the moment). When I boot from the USB it fails when expanding the file. It stays on 0% and fails after around 90 seconds. The error is 0x80070017. As the hash is correct and I am using USB I guess it could be a hardware problems. Any advice how to get Windows 7 installed? The machine is a Dell Studio Slim.

  • Cleaning up temp files in OSX

    - by deddebme
    I was a Windows person for more than 10 years. Around 4 months ago, I switched to Mac, and I have never looked back. But there is one thing that bothers me, which is my Mac partition volume is losing space slowly and gradually. I am pretty sure there are a lot of orphaned temporary files laying around in the volume. I know where to find the obsoleted temp files in my Windows partition, how about in Mac OSX?

  • Why would my HDD main partition suddenly become hidden?

    - by Luis Oscar
    A few days ago I was using my computer as usual and I turned it off. The next day it wouldn't boot up. It just stayed after the hardware diagnostic window on the intermittent underscore screen. So clearly It wasn't booting up. I tried turning it on and off a couple of times with no avail. Finally I used windows 7 disk and it seemed as if there was no HDD. not even the installation would see the HDD. So i thought it was dead, i bought a new one installed it with windows and used a external case with the old HDD. plug it in and still couldn't see it. I finally downloaded a partition program EASUS or something and my HDD was there listed WITHOUT a system letter. I could however explore it and i set it as Unhidden and it came back to life. I could see it normally. I really just wish someone could explain to me what happened here, was it a virus? does it means the HDD is about to die? How can i prevent this or what should I do now? should i stop using this OLD HDD? Thanks

  • Disk boot failure, insert system disk and press Enter.

    - by torbengb
    Similar to this related question, I came home and found that my media center pc showed this message, Disk boot failure, insert system disk and press Enter Before I do anything with the (defective?) harddisk, what are the best first steps I can take to fix this with a minimum of damage? Normally the machine (Win Vista) is always on and never reboots by itself (Windows auto-updates are disabled too). Something must have caused it to reboot, though I'm sure we didn't have a power outage. The machine can't reboot on that disk, but it will boot on another disk I just plugged in for testing. I haven't changed anything, or even touched the machine, for several days, and it has been running fine until now. I did replace the power supply some weeks ago, because the old one suddenly stopped working. It has been working fine with the replacement PSU.

  • pendrive automount not working

    - by Delirium tremens
    There are lots of ways to disable pendrive automount. I used one, but regreted, forgot which one and now need to reenable pendrive automount. It may have been a changed setting after pressing a button while booting Ubuntu or a deleted folder named something20090101 or 01012009something or whatever as long as it's a word and a date... If I don't want pendrive viruses, it's disable autorun, but keep automount enabled, right? blush

  • How do I protect business critical data against fire?

    - by Bill Knowles
    We have 72 hard drives that contain our webcast inventory. The number is increasing. We're located in a frame building and we are afraid of not only fire, but catastrophic fire. I've priced fireproof safes that hold to the required 125F for hard drives. Their price is through the roof. Seems to me if we made backups of each of the hard drives and stored them off-site somewhere, or contracted with an online backup storage company, we might run up a bill buying backup drives that would approach the $7,000 cost of the safe! What's the best way to protect our data from the risk of fire?

  • How do partitions help in optimizing the harddrive?

    - by Fasih Khatib
    I was recently reading a guide on Tom's Hardware about how to optimize the harddrive. They listed creating partitions as one of them. They said keeping the various files seperate is a good idea as it reduces the read/write cycles required. Now my querry is: what size partitions do i make for my 500gb harddrive. Its completely blank. I will be installing WIN7 in it. My usual strategy is to divide it into two equal partitions. Is it the optimum size?

  • How much of slow and fast flash memory a "flash memory" have?

    - by gsc-frank
    Trying to know what is the best of my flash memories to use ReadyBoost I realize that I don't know how much of fast flash memory each of my flash drives have. One can read: In some situations, you might not be able to use all of the memory on your device to speed up your computer. For example, some flash memory devices contain both slow and fast flash memory, but ReadyBoost can only use fast flash memory to speed up your computer.
