  • OSX: cant create a partition because drive is locked

    - by Alain
    Problem: I have a USB key with Mountain Lion on it and I want to install it on my macbook pro. I deleted the existing partition on the laptop and wanted to created a new one were to install the OS but cant because everything in the partition tab for the drive is grayed out. Basically, I can't do anything until I unlock the partition So the question is: how to unlock a partition from disk utility or the command line.

  • External USB attached drive works in Windows XP but not in Windows 7. How to fix?

    - by irrational John
    Earlier this week I purchased this "N52300 EZQuest Pro" external hard drive enclosure from here. I can connect the enclosure using USB 2.0 and access the files in both NTFS partitions on the MBR partitioned drive when I use either Windows XP (SP3) or Mac OS X 10.6. So it works as expected in XP & Snow Leopard. However, the enclosure does not work in Windows 7 (Home Premium) either 64-bit or 32-bit or in Ubuntu 10.04 (kernel 2.6.32-23-generic). I'm thinking this must be a Windows 7 driver problem because the enclosure works in XP & Snow Leopard. I do know that no special drivers are required to use this enclosure. It is supported using the USB mass storage drivers included with XP and OS X. It should also work fine using the mass storage support in Windows 7, no? FWIW, I have also tried using 32-bit Windows 7 on both my desktop, a Gigabyte GA-965P-DS3 with a Pentium Dual-Core E6500 @ 2.93GHz, and on my early 2008 MacBook. I see the same failure in both cases that I see with 64-bit Windows 7. So it doesn't appear to be specific to one hardware platform. I'm hoping someone out there can help me either get the enclosure to work in Windows 7 or convince me that the enclosure hardware is bad and should be RMAed. At the moment though an RMA seems pointless since this appears to be a (Windows 7) device driver problem. I have tried to track down any updates to the mass storage drivers included with Windows 7 but have so far come up empty. Heck, I can't even figure out how to place a bug report with Microsoft since apparently the grace period for Windows 7 email support is only a few months. I came across a link to some USB troubleshooting steps in another question. I haven't had a chance to look over the suggestions on that site or try them yet. Maybe tomorrow if I have time ... ;-) I'll finish up with some more details about the problem. When I connect the enclosure using USB to Windows 7 at first it appears everything worked. Windows detects the drive and installs a driver for it. Looking in Device Manager there is an entry under the Hard Drives section with the title, Hitachi HDT721010SLA360 USB Device. When you open Windows Disk Management the first time after the enclosure has been attached the drive appears as "Not initialize" and I'm prompted to initialize it. This is bogus. After all, the drive worked fine in XP so I know it has already been initialized, partitioned, and formatted. So of course I never try to initialize it "again". (It's a 1 GB drive and I don't want to lose the data on it). Except for this first time, the drive never shows up in Disk Management again unless I uninstall the Hitachi HDT721010SLA360 USB Device entry under Hard Drives, unplug, and then replug the enclosure. If I do that then the process in the previous paragraph repeats. In Ubuntu the enclosure never shows up at all at the file system level. Below are an excerpt from kern.log and an excerpt from the result of lsusb -v after attaching the enclosure. It appears that Ubuntu at first recongnizes the enclosure and is attempting to attach it, but encounters errors which prevent it from doing so. Unfortunately, I don't know whether any of this info is useful or not. excerpt from kern.log [ 2684.240015] usb 1-2: new high speed USB device using ehci_hcd and address 22 [ 2684.393618] usb 1-2: configuration #1 chosen from 1 choice [ 2684.395399] scsi17 : SCSI emulation for USB Mass Storage devices [ 2684.395570] usb-storage: device found at 22 [ 2684.395572] usb-storage: waiting for device to settle before scanning [ 2689.390412] usb-storage: device scan complete [ 2689.390894] scsi 17:0:0:0: Direct-Access Hitachi HDT721010SLA360 ST6O PQ: 0 ANSI: 4 [ 2689.392237] sd 17:0:0:0: Attached scsi generic sg7 type 0 [ 2689.395269] sd 17:0:0:0: [sde] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB) [ 2689.395632] sd 17:0:0:0: [sde] Write Protect is off [ 2689.395636] sd 17:0:0:0: [sde] Mode Sense: 11 00 00 00 [ 2689.395639] sd 17:0:0:0: [sde] Assuming drive cache: write through [ 2689.412003] sd 17:0:0:0: [sde] Assuming drive cache: write through [ 2689.412009] sde: sde1 sde2 [ 2689.455759] sd 17:0:0:0: [sde] Assuming drive cache: write through [ 2689.455765] sd 17:0:0:0: [sde] Attached SCSI disk [ 2692.620017] usb 1-2: reset high speed USB device using ehci_hcd and address 22 [ 2707.740014] usb 1-2: device descriptor read/64, error -110 [ 2722.970103] usb 1-2: device descriptor read/64, error -110 [ 2723.200027] usb 1-2: reset high speed USB device using ehci_hcd and address 22 [ 2738.320019] usb 1-2: device descriptor read/64, error -110 [ 2753.550024] usb 1-2: device descriptor read/64, error -110 [ 2753.780020] usb 1-2: reset high speed USB device using ehci_hcd and address 22 [ 2758.810147] usb 1-2: device descriptor read/8, error -110 [ 2763.940142] usb 1-2: device descriptor read/8, error -110 [ 2764.170014] usb 1-2: reset high speed USB device using ehci_hcd and address 22 [ 2769.200141] usb 1-2: device descriptor read/8, error -110 [ 2774.330137] usb 1-2: device descriptor read/8, error -110 [ 2774.440069] usb 1-2: USB disconnect, address 22 [ 2774.440503] sd 17:0:0:0: Device offlined -

Today I recieved a 1394b 9 pin to 1394a 6 pin cable which allowed me to connect the "EZQuest Pro" via Firewire. Everything works. When I use Firewire I can connect whether I'm using Windows 7 or Ubuntu 10.04. I even tried booting my Gigabyte desktop as an OS X 10.6.3 Hackintosh and it worked there as well. (Though if I recall correctly, it also worked when using USB 2.0 and booting OS X on the desktop. Certainly it works with USB 2.0 and my MacBook.) I believe the firmware on the device is at the latest level available, v1.07. I base this on the excerpt below from the OS X System Profiler which shows Firmware Revision: 0x107. Bottom line: It's nice that the enclosure is actually usable when I connect with Firewire. But I am still searching for an answer as to why it does not work correctly when using USB 2.0 in Windows 7 (and Ubuntu ... but really Windows 7 is my biggest concern).

  • convert multiple segments of DVD to FLV

    - by Josh
    I have a DVD of footage that I need to convert to FLV. I would rather not convert the whole disk as I only need specific segments. Is there a program that I can input start and end times and to get multiple files of these segments? Can you also advise on the best settings to use for best quality at the smallest file sizes. I'm working on a Vista 64bit machine. Thanks. Josh

  • Using an SSD with no AHCI [ICH7 base] - Windows 7 hangs frequently

    - by h4xnoodle
    I have a Shuttle Intel G31 + ICH7 (base -- not M/R etc) system. I just bought an OCZ Vertex 3 120gb [VTX3-25SAT3-120G] which includes the Sandforce 2218 firmware. The ICH7 does not support AHCI. I understand that this can be a problem. What I don't understand, is if it's necessary to have the proper performance of this drive. I know that without AHCI I may get a limited read/write speed -- this is fine. What my concern is, is the constant freezing/hangs I'm getting with Windows 7 on any disk activity. The 'Highest Active Time' flip-flops from 0 to 100% every minute or so regardless of large or small files. EDIT: The threads/processes with the highest response time is the kernel. I've been reading about other people with Shuttle SG31G2s, and they seem to be using SSDs no problem. Is this the controller's fault? The fact that I do not have AHCI enabled? It makes sense to me that if this SSD requires AHCI features that it would cause Windows to hang, but I would like to fully determine my situation before returning things/reformatting. To initially have my drive recognise the SSD at all, I had to change the BIOS option to Force Gen II instead of Auto for the SATA controller. I then installed Windows with no problem. There were no errors in the event log related to disk usage, but watching the perfmon I could see the highest active time and the processes (usually pagefile.sys being written to, or chrome/firefox caching) which was correlated to the hanging. So now what I need answered is: should I be returning this SSD and getting one with a different controller, or returning the SSD all-together as it will never work out and I will continue to get these hangs. Posts I've read: Windows 7 New SSD SATA AHCI? -- suggests to use AHCI http://forums.anandtech.com/showthread.php?t=2189868 -- Sandforce issues Windows 7 freezes with SSD -- and attached posts Why does my Windows 7 PC / SSD drive keep freezing? -- this is not the controller I have, but still a related issue. Windows 7 hangs after longer inactivity of user -- also tried messing with power settings with no luck. It was already set to 'Never' for turning off HDDs.

  • pfsense log file retention

    - by Colin Pickard
    We have a pfSense firewall in our datacentre. By default, pfSense is only storing 500K of firewall filter logs, which is only a few hours for us. How can I increase this? pfSense uses clog rather than the usual BSD newsyslog. I only want the log for debugging firewall rules, not compliance or anything, and the firewall has 100GB of spare disk space, so I'd rather have the logs on the firewall itself than set up a syslog server.

    I just bought new SATA 1TB Baracuda HDD, I inserted and my windows didn't recognize it. Because I didn't have any other OS or anything to format it I used Centos i386 installation to format it. I of course disconnected my original disk from the motherboard and formatted it using CENTOS.. but now when I come back to the windows I can't format this HDD. Its recognized as RAW.

  • Using hdparm for better performance on Web Servers

    - by Rishav
    I just heard about using hdparams to optimize the Hard Disk Performance of a server ? Is this common practice ? What file systems do you use ? I generally deploy on the second last release of Ubuntu for stability reasons, do you some other filesystems or use distributed file systems from the get go ? Do the hdparam settings change for different File systems ? I haven't tried this yet, so how much difference do changes like this make ?

  • Deleting windows.edb and unchecking Indexing service lead to hard drive file records swapping

    - by linni
    I followed the instructions listed here:http://www.mydigitallife.info/2007/09/18/turn-off-and-disable-search-indexing-service-in-windows-xp/ to free up space on hard drive by deleting the windows.edb indexing file... I also stopped windows search service as mentioned in the comments following the article. In addition to unchecking the "Allow Indexing Service to index this disk for fast file searching" check box on the properties dialog for the C:\ drive, I did the same for two usb connected hard drives (J:\ and I:\ ). I'm not sure why I did that, thought it might shrink the windows.edb file so I wouldn't have to delete it (which sounded a bit risky in my ears at the time). The file of course didn't shrink so I ended up deleting it and freeing up over 3 GB of space, yeehaw. However, as soon as I had done this I could not access the usb connected hard drives anymore. The error I got was "I:\photos is not accessible" "The file or directory is corrupted and unreadable" when I tried to open the photos directory on I:\ Here is where I enter the twilight zone... I try disconnecting I:\ usb hard drive. But XP shows me that instead J:\ drive has disconnected and I:\ is still there. So I disconnect both drives and restart the computer. I then connect one drive, but it lists up the contents of the other drive on root level. I tried connecting the drives vice versa and the same thing happens. I try taking one of the hard drives to another computer and when I connect it there it lists up not its own contents but the contents of the other hard drive and gives the same error as above when I try and access any of the folders (even folders on the root that have the same name as folders on the other drive (e.g. J:\photos and I:\photos)??? And no, this is not a me mixing up my drive letters. Computer Manager - Disk management shows the same result as explorer: The drive size is correct (one is 500GB, the other is 640GB) but the drive name is of the opposite drive, as long as the contents. Also, one drive was full of data and the other almost empty but they incorrectly show their free space status of the other drive. Somehow the usb drives seem to have switched file tables, file records, boot records or something, extremely weird! Even weirder, if I try and create a text file or folder on this drive, it works fine, accessing them, saving, whatever, all good, but accessing any other data on the drive gives me an error. Does anyone have a clue what is going on and more importantly, how I can restore the correct folder listings to access my family photos ??? cheers, linni

  • Windows 7 backup and restore: Is each backup incremental or complete?

    - by Margaret
    I have a computer that's been taking backups using Windows 7's Backup and Restore feature. However, I now need to reclaim hard disk space, and am trying to figure out what I can safely delete. When I go into the Backup and Restore options on the machine, it shows several backups. Is it safe to delete the older ones? Or is it an incremental backup, that means that files not changed since before the last backup would then be lost?

  • VMWare Server - Writing files to virtual hard drive performance

    - by Ardman
    We have just moved our infrastructure from physical servers to virtual machines. Everything is running great and we are happy with the result of the move. We have identified one problem, and that is reading/writing performance. We have an application that compiles files and writes to disk. This is considerably slower on the new virtual machines compared to the physical machines. Is there a performance bottleneck when writing to a virtual hard drive compared to a physical hard drive?

    I have a domain controller running on Windows 2008 Server R2 and users login to application servers on which Windows 2003 Server SP2 is installed. I have applied a Group Policy to clean temporary internet files on exit i.e to delete all temporary internet files when users close the browser. But the group policy doesn't seem to work as user profile size keeps on increasing and the major space is occupied by temporary internet files therefore increasing the disk usage. How can i enforce automatic deletion of temporary internet files?

    I have a requirement for a resilient MSMQ setup on VMWare ESX5. I am aware that we cannot allow the queue storage to be shared as it must be installed on physical disk mount, e.g. it cant be an CIFS or DFS Share. The following constraints apply: We don't use windows clustering We dont't rely on hot standbys Is there a way I can replicate the queue storage to another platform so that it can assume MSMQ duties on failure of the primary platforms using any method including queue forwarding?
