Drive Compression not available - why?

I just bought a new 3 drive from Western Digital Passport.

After formatting the drive (with 16 k as the sector size) I added a number of files and folders to it. Now, I want to compress the data in the file.

When I'm looking at the properties of this drive, the ability to compress the data in the file is hidden. Display the properties of one of the files on this drive poster option compress the file read-only data.

Why is this happening?

Could it be because that:

By default, the maximum cluster size for NTFS under Windows NT 4.0 and later versions of Windows is 4 kilobytes (KB). This is because NTFS file compression is not possible on drives that have a larger cluster size.

https://support.Microsoft.com/en-us/KB/140365

Check the cluster size of one of your disks where compression is allowed by opening a (possibly be run as an administrator) command prompt and issue the example command depending on your C drive:

fsutil fsinfo ntfsinfo c:

    My sales representative Dell told me that this kind of upgrade is not possible, the 600GB 15,000 rpm SAS drives is not available...

    My client is very upset by this situation and I'm trying to find another solution.

    Is it possible fill completes the picture with the original disc Seagate Cheetah 15K 3.5 "600 GB SAS 6 GB/s 24 x 7, type ST3600057SS instead of the original Dell disks?

    I can see the Dell drive (P/N 0944832 - 01) are Seagate brand and type is exactly the same.

  • Realtek driver update not available for Windows XP on Vista B4 upgrade to Windows 7

    Hi all I set up my cell phone before installing Windows 7.  The compatibility check says I need to download the latest driver for Realtek RTL8139/810xFamily Fast Ethernet Realtek Semiconductor NIC and before reinstalling after installing Windows 7.  However, when I tried to do this Realtek said it is not available. Any advice on what to do? If I install Windows 7 I'll be without driver, really worried then. Thank you in advance, really need help. Thank you in advance, Ros

    If the manufacturer of the hardware does not support the operating system to use, the only possibilities are driver compatibility mode Setup, hope that works of an integrated 'generic' or replace such hardware with something that is supported on the operating system, that you choose to run by the manufacturer of said material.

I joined Dell Community a few months ago and downloaded and installed DELL QUICKSET from Dell Support site as an update. Before installing Quickset suite Bluetooth to my laptop would work fine, but after installing quick adjustment, it has stopped working. Without doubt, I disturbed the sequence

I couldn't find a driver Bluetooth of independent outside the BHS + WLAN driver on the dell support Web page. The laptop recognize the Bluetooth and Wireless LAN adapter but cannot start the two. I found the wireless LAN driver, but the driver now Bluetooth is not available on the official Dell support site. I tried online diagnostics and research on the Dell Support programs but could not find.

  • HP Pavilion 15 ab031ax: R7 M360 driver is not available. Need help.

    My laptop is a HP Pavilion 15 ab031ax which runs in AMD A10 8700 P with AMD R7 M360.

    My problem here is that provided in the HP support display driver does not help, and it's corrupted. I tried downloading another machine always with the same result.

    I checked once again, that I noticed that it updated June 23, 2015, but unfortunately the same thing. Files is corrupted.

    Now after installing the graphics driver provided by the site Web of AMD, I've only M365DX R8 as my video driver but my screen shown as Microsoft Basic display adapter.

    When I click Update for the MBDA, he says that it is up-to-date. When I tried to manually install M360 R7 or AMD R7 Series. It won't let me.

    I asked a technical support in this regard, they have tried to do this remotely, but failed. When the display driver file will be updated?

    I can't do my job without him.

    You are the very welcome.

    I'm sorry that it didn't work.

    Give this one a try and if it no longer works, thank you for posting the material for the video controller ID, so I can explore folders of different driver for a corresponding ID.

    This driver at least shows support for an AMD Radeon R7 M360 graphics adapter in the file of configuration information.

    The first is that I posted just showed several R7 without a more detailed description.

    All the drivers have been found except for one and I don't know which device needs a driver.  When I click and highlight the laptop I'm working on and has all the problem I get now are the error message that the driver is missing or there is no driver.

    At the moment can not find the device that needs a driver and not find a driver that is missing.  I hope someone can give me some suggestions about where to look for the answer to this problem...

  • Equium A60: A new version of the display driver is not available?

    I think that this may be the cause of a certain display problems that I'm facing with this machine.

    Many different series laptop is delivered with the same graphic card.
    It of possible that the latest graphic driver have been placed in the different laptop computer category. I recommend checking out the different series of the same graphics card which is used in your Equium and maybe you will find the most recent version of the driver.

  • TS140 optical drive drivers not available for download?

    Try to install Windows 7 on TS140. Support/drivers page offers the sunix as a driver for the storage Extender. Have expanded on a portable player. Win 7 install almost immediately calls for drivers for the optical drive, but when I browse to the INF folder, it does not have the appropriate drivers. Am not finding any drivers for storage devices support/download.

    Can someone point me in the right direction? TIA.

    Finally, I whipped this problem using a laptop optical drive (usb) for installation. Once the installation has been made, I brought the network via USB key drivers. Once the network was functional, the rest of the drivers became available via Windows update. It took about 24 hours, given that Microsoft takes control of updates.

    Hello

    The latest versions of Conexant audio driver (currently 8.65) do not support audio downtime such as the legalization of the volume. Equalization of the volume is pretty important and I don't know there are people who use other options too.

    Conexant overall doesn't seem to be too good to make the drivers. It is a 170 MB download for a pilot of 4 MB (which they refuse to do know themselves), followed by of a probably huge facility some DSP Dolby and the 3D effect that cannot be chosen. This allows the stereo mix became finally possible with the latest versions, but now they said bug. Why companies that fail to deliver appropriate products is not more these days out of business?
