How to make hard disks hidden?

I Have 2 HDs and i want to use them on my macbook via network and to do it, those disks needs to stay connected to my sister's mac pro. This disks have confidential and work files that no one can't have acess. Does exist a way to make this disks hidden on my sister's mac and mounted only on my macbook?
One of this disks are used to keep my files and the other one is used by Time Machine backups.

You can change Sharing & Permissions on those drives so that only you can access them. Right click the hard drive icon and select Get Info.
In the bottom of the new pane you have to click the padlock and authenticate. Sharing and Permissions should show you have Read & Write privileges. Change "everyone" to no access.

    I want to give away or sell a 6500/250 running 7.6.1. How can the hard disk be erased so that the data are gone, not recoverable? thanks, LifeisRich

    I'd recommend that you check for Mac User Group(s) in Orange County.  That's where you'd likely find a diehard Mac fanatic who might want to add your 6500 to his/her collection.  Even if you got nothing for it, it would be better than e-cycling it.  I upgraded my 6500/275 with what was a "large" hard drive at the time (15 GBs), maxed the memory at 128 MBs, installed the 512K L2 cache card, a better ATI Rage Pro PCI graphics card, a USB PCI card, and an internal 56K modem.  With it running OS 9.1, it did all of the pre-OS X stuff I needed it to do.  As I previously mentioned, it's a nice-sounding MP3 player.  Internet Explorer 5.1.7 (the final release from 2001) kept it useful for surfing the web up until 2005, when it became too outdated/incompatible with many web sites.  Unfortunately, the demands of the internet and the need for a modern browser, as well as faster processing to digest it all, are what retired many older Macs from active duty.  So my (2) 6500s and (3) 6400s (same tower design) sit in storage.  There is one concern that I'll pass along: The motherboard has a 4.5-volt alkaline battery, that's a small, black plastic cube, secured in place by velcro.  If your 6500 has been disconnected from electricity for a long time, the battery will undoubtedly be dead.  Unlike the many Apple computers that used a small ½AA lithium battery (that I've never seen leak when completely dead), the 6500's battery can and usually does start leaking.  Because the motherboard sits vertically oriented on its side edge when installed, the leaking battery will drip alkaline solution down the board, corroding any components in it path.  I've seen motherboards ruined from this.  If you're going to give it away or sell it, you might want to pull the motherboard (remove the two machine screws on the rear I/O panel, next to the pull tabs).  Slide out the board and unplug the battery's small connector (has red & black wires), then lift up on the battery, while holding down the "toothed" velcro mount with something non-conductive, like a popsicle stick.  Once it's free, dispose of the battery.  If you're interested, a replacement can be purchased for about $5-$7 from battery specialty retailers - it's a Rayovac 870 or 871.  Even if you don't replace it, removing one that will eventually leak is a good idea, (hopefully) before any damage is done.

  • How to stop hard disk noise on T61

    Hello everyone,
    I have a T61 and everything works well except the hard disk which is constantly working. The result is a gentle noise on the bottom right
    of laptop, always present. I used to have a T42 which when configured on XP to turn off hard disk (through power management), completly turned it off. I could then read or write long open files with a completly silent laptop (used tpfancontrol for controling fan, but this is not the problem here) until I save document or explcitly trigger the hdd (a completly silent laptop is a delight!).
    The noise of the present T61 is bearable, a kind of a whisper, but once it stops it gets really better for your ears. My problem is that the power manager (set to turn off disk after 3 minutes) works, but something is constantly accessing the hard disk, which prevents the power manager to turn the HDD off. So, sometimes it happens that after 3 minutes the HDD stops, and a hsort time latter, say 15 seconds, it turns on again because "something" used the hdd.
    The worse is that, most of the time, the hdd is triggered prior to the 3 minutes, so that it keeps always running!!
    I can see this as the hdd green light flashes.
    This is always the case, with or without internet, AC or DC.
    I tried to stop some services (including indexing), but I stopped looking because of the number of services to check!
    How do I know what service/program is being written on hdd at the specific time where I notice it, or makes it work, such that I can possibly disable it?
    This is maybe a XP SP§ issue I think, but I think many here have noticed this constant activity on lenovo´ T61?
    Any advice on possible strategy to find out who write what on the hdd or other solution?
    I really plan to fix this problem because the T61 as it is now is really good (with however minor problems),
    and i think many of us should benefit from this issue..

    I would say it´s quite impossible on newer systems, to get the harddrive off for more than a few seconds.
    Many user have tried that, but no one had success.
    Another, but little dirty, possibility is, to take some piece of rubber or something and put it under the palm rest where the hdd is.
    But beware, there is a little hole in hdd that have to be open to get some air.
    This dirty trick will lower the permanent sound of your hdd.

  • How to find Hard Disk Serial

    Hi, I have a program written using AIR for a client, and I dont want him to make millions of copies of my software, I would like to know exactly how many copies of my software he is using, so I figure, thats easy I will bound the software to the hardware, the hard disk serial.  Than one problem surfaced, how the heck do I find the hard disk serial using AS3?
    Or is there a easier way for me to keep track of the software? the clients will install the software on machines that do not have internet access.  And the amount of software is not a big number, maybe 50 copies/machines per month.
    Thanks in advance.

    Is it installed on an other system? If so you can see the serial number in the About Aperture window.
    If not ant you wiped your disk and Aperture is no longer installed there is no way to find the serial number apart from the hard copy you had when you bought it. 
    See Pro Application Replacement Serial Numbers and give Apple a call. They are pretty good at working with you to try and recover the serial number.

  • How to prevent hard disks from sleeping

    Hello
    I have recently installed a SSD for system drive in my machine, and now realise what a bottle neck the old, standard hard disk had been. Booting is now extremely fast, as is opening applications. This speed has alerted me to another problem. My hard disks keep falling asleep, which slows down operantion of the machine significantly. For instance, to log into this forum, I used 1Password. When selecting the log in menu item from 1Password, there was several seconds delay before one of the hard disk (I have four inside the machine, one external Drobo, and one external eSata drive) came alive. When it had, Safari could take me into the site. There constant delays like this when I use Safari, for example. These delays are very frustrating, so I want to keep all my disks awake constantly.
    Thing tried so far:
    The worst problem was the Drobo, because it has three disks inside that wake up one after the other, a very slow process, and the Drobo is slow in itself. So I installed a little script that does a touch command every five minutes, to prevent the Drobo from sleeping. It seems this has helped. But the other disks keep falling asleep all the time. I have set Cocktail to prevent all disks from sleeping - no effect. The Energy Computer Sleep setting is set to Never.
    Any ideas will be much appreciated. This sleep issue keeps bugging my all day long.

    In the Energy Saver system pref, are any of the boxes checked?
    If it were me, I guess I'd try clicking the 'restore defaults' button in Energy Saver, restart the computer, and then go back into the Energy Saver and set the computer sleep to either 3 hours or never, and uncheck the 'put hard disks to sleep when possible' box. You might try 3 hours instead of never and see if that makes a difference.

  • How to make boot disk for MacBook Pro with Mavericks pre-installed

    Hi -
    I recently bought a new 15" MacBook Pro with Retina Display, which came pre-installed with Mavericks (10.9.0).  I want to make a bootable USB disk of the system software, and have successfly used DiskMaker X (formerly Lion DiskMaker) to make the USB boot disks for Lion and Mountain Lion.  In those cases, however, I was running earlier versions of the OSX, and downloaded the new OSX version -- Lion and Mountain Lion -- from the App Store in order to make to make the disk.  In this case, however, Mavericks was pre-installed, and I was unable to download it from the App Store (an alert said that it couldn't be installed on this computer... presumably because it was already installed).  I would apprecite any suggestions as to how I can create the boot disk without the ability to download Mavericks.  Thanks very much for any help anyone can provide.
    Shelly

    Open App Store and locate the full installer download file (5.29 GBs) for 10.9.1. Download to your computer.
    Make Your Own Mavericks, Mountain/Lion Installer
    After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
        2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
    Open Disk Utility in your Utilities folder.
    After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
    Select the volume you just created (this is the sub-entry under the drive entry) from the left side list.
    Click on the Erase tab in the DU main window.
    Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
        3. Use DiskMaker X to put your installer clone onto the USB flash drive.
    Make your own Mavericks flash drive installer using the Mavericks tool:
    You can also create a Mavericks flash drive installer via the Terminal. Mavericks has its own built-in installer maker you use via the Terminal:
    You will need a freshly partitioned and formatted USB flash drive with at least 8GBs. Leave the name of the flash drive at the system default, "Untitled." Do not change this name. Open the Terminal in the Utilities folder. Copy this command line after the prompt in the Terminal's window:
    sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
    Press RETURN. Enter your admin password when prompted. It will not be echoed to the screen so be careful to enter it correctly. Press RETURN, again.
    Wait for the process to complete which will take quite some time.

  • How to make a file "hidden"

    This question might sound stupid but here it goes. How do you hide a file?, i know how to view hidden files (onyx) but i dont know how to make a normal file as hidden

    On a related note, I am looking for a way to hide only those files that I want hidden. Some hidden files I need to access on an almost-daily basis, but others, like .DS_Store and such, I'll never need direct access to.
    So, is there an official way to set up a custom list of file names and/or file regex patterns so only certain files are hidden from the Finder?
    Thanks!

  • Help - TechTool makes hard disk unreadable

    After running TechTool's Volume Structure repair, my hard disk is now un-bootable and unreadable. Subsequent runs of TechTool state that the Volume Structure is OK, but Apple's Disk Utility says the volume is in need of repair and can't be repaired. Any idea why the difference between the two disk programs? And more important, how can I repair the disk?
    Details: Mac G5 Dual 1.8G, OS 10.4.11 was apparently running OK until I did a routine scan of the disk with TechTool Deluxe (v 3.0.3) which I received from Apple with their AppleCare protection plan several years ago. It detected some unstated problem, and I chose the repair option. The analysis showed a few numbers in green and nothing in red (I recall seeing B-Tree depth was reduce and more free nodes). The Techtool repair appeared to go OK with no further messages. However, now the computer would not boot (gray screen with several languages almost immediately). I booted from my original OS10.4 disk and ran Apple's Disk Utility. It shows the volume is not mounted (grayed out). The "Verify Disk" says "Invalid B-tree node size" and "Volume Needs Repair". Running "Repair" quickly states the same plus "Volume check failed" and "Volume could not be repaired because of an error". Subsequent runs of TechTool says the volume is OK. How can one program say the volume is OK and the other say it's not? How can I recover?

    You used too old of a version of TechTool. That version actually will ruin a Tiger install, especially 10.4.11.
    Your only hope of repair will be by running the latest version, the 3.1.2 updater. Other utilities are usually unable to repair damage done by the wrong version of TechTool or TechToolPro.
    Otherwise it's Erase and Install time. Let us know if you need help with that.

  • How format the hard disk in single-user mode

    Hi all, i would like to format the internal hard disk of my macbook pro 13'' through single-user mode. How can I do it, please?

    Ok, to do that you need to hold c and boot off the 10.6 installer disk and second screen in under the Utilities Menu is Disk Utility.
    You can then select the hard drive makers name (your "bare metal") and peform the wipe/format of the entire drive or a "partition" on that drive.
    In the picture below there is only one partition, the Mac HD. In the picture above there are two partitions which both would show up under the hard drive makers name and both or either partition can be wiped in Disk Utility.
    Use the Security Option to Zero your hard drive of all lingering data.
    When you Quit Disk utiltiy, your back in the installer and can quit or install OS X.
    Note: messing with Disk utility will erase all data on the drive, if there is something you need to recover better stop and ask!
    If you don't see your internal boot drive in Disk Utility, the drive is dead.

  • How to make hard reset on Toshiba Journ.E Touch?

    How to reset hard the Toshiba journ e touch?
    Thanks

    The only way I have managed to recover completely, which appears to be equivalent to a hard-reset.
    Apply (or re-apply) the firmware update using SD card. Make sure to get the correct file that corresponds to your device. (mine is PX1530U-1ET1)
    be aware that any previously used SD card needs to be formatted by a Windows PC to be totally successful.
    I had problems getting the card recognised by the journe until I did a complete reformat of the card. (using quick format isn't thorough enough).
    1. back up your data
    2. put firmware onto card using a Windows PC
    3. plug the charger into Journe touch
    4. slide reset switch to left and back to the right. (with a paper clip)
    5. insert your firmware SD card
    6. power up and the Updating message should pop up.
    It usually takes a couple of minutes to get things back to usable.
    power off and remove the SD card. (keep it safe for future problem resolution)

  • DV9925nr - How to Backup Hard Disk Drive After S.M.A.R.T. Drive Failure Message

    I purchased a DV9925nr laptop from Bestbuy about 13 months ago. Six months ago it started having the sporadic and randomly abrubt shutdown problem that so many others seem to be having. 
    Two days ago it developed a new problem:
    I left my laptop on for a few minutes and when I returned, it was to a black screen with this message: "SMART Drive failure predicted on Hard Disk 4. WDC WD2500BEVS - 60UST0-(S1); warning: Immediately backup your data and replace your hard disk drive. A failure may be imminent. Press F1 to continue."
    My question:
    We have a network with two laptops and a desktop computer. There is plenty of hard drive space on the desktop system. My father has the same exact laptop model as mine. Can I put my hard disk drive into his second disk drive bay so that I can backup my files over the network to my desktop system? How would the laptop know which hard drive to boot from since they both have the same operating system on them (I am not familiar with SATA drives)?
    I hope I didn't buy a lemon. Any help would be greatly appreciated.

    Are you trying to do this while booted from the OS or from the install Disk? If your booted into the OS then the repair option shouldn't be click-able. Beyond that, there might be some 3rd party software that could force a reformat and/or erase. I did try to find you something but didn't come across anything specific to what your trying to do. You probably already know this, but the purpose of S.M.A.R.T. is it acts as an early warning indicator. This means the drive is no longer dependable and may fail without warning in the near future, resulting in losing all data. With that being said, I've used a hard drive that S.M.A.R.T. indicated was failing for 3+ years without a hick-up. I don't use it for anything imported though. When I have more time and if I come across anything that might get the job down, I will add to this posting. The worst case scenario is that there is no way to reformat and/or erase the drive due to the state it's in. At that point, the only thing left to do is recycling the drive.
