No longer can write to my external SATA drive...

I was editing in FCP Studio 2 on a my MacPro 2x2.8 Quad Core, running MacOS 10.5.2, connected to a Highpoint X4 SATA drive, via the Highpoint RocketRaid 2314MS card. At some point the MAC detected a problem with the drive, and apparently it has changed the drive to read only. My timeline plays OK, but a lot of clips are marked as off-line, although I re-rendered them and they play. I ran the internet verification check from Highpoint, and it said the drive was normal. MAC disk utility will not let me change permissions on the external SATA. What should I do? Edit deadline approaching...there goes the weekend.

Well, the tech-support guy at Highpoint was going to e-mail me some steps, after he talked with someone about some MAC procedures. He thought that I would have to insert some code. There are three UNIX files on the drive that are trying to"fetch" something. Since my permissions have changed, I can't delete them. The e-mail from tech support never arrived last night. I'm in tthe CST zone, so it's still about two hours until Highpoint opens their doors. The RAID warning lights gave never changed from green to red. No beeps or chirps either. The on-line drive verification that took 3 hours, said the drive status was Normal.

  • Can't mount my external SATA drives - help please

    I have two SATA II drives taken from my now, knackered, PC and I want to mount them from my Macbook Pro. I have a the Sonnet Tempo eSATA card which has two sockets and I have connected that to Sharkoon SATA Quickport Duo which allows me to physically connect to the two drives. I don't need write access, just read access. However, when MacOS goes to mount the drives it tells me "The disk you inserted was not readable by this computer" and presents me with three options "Initialize...", "Ignore" and "Eject".
    When the drives were installed in the PC they were configured for RAID 0. I have a suspicion that this is what's causing the problem. Can someone please help me with getting these mounted? Do I need some special software? Am I missing something?
    Thanks all

    Seems like I'm on my own with this one then.

  • How long can i keep my external firewire drive on?

    I moved my itunes and iphoto library to my new iomega ultramax 1tb. i usually keep my imac on for several days, only leaving it to energy save mode when i am not using it.
    can i keep my drive always on as well?

    Yes. You can keep it on. There is a setting in the +Energy Saver+ pane of Disk Utility to +Put the hard disk(s) to sleep when possible+. That would apply to the external drive, to save energy and reduce wear on the drive.

  • My iMac can no longer find one of the external hard drive

    My iMac can no longer find one of the external hard drive. It was finding it once in awhile and during one of those times I ran Disk Utility and all was OK. Any ideas?

    Well duh.  I restarted the router and then it was able to find the printer.  There you go.  Thanks.

  • Hi - my 2011 Mac Pro no longer recognizes devices in the usb ports, I've been told it's the logic board.  is there a way I can connect the iomega external hard drive to it through the firewire or thunderbolt ports?

    Apple uses many manufacturers and it's massive also websites prefer to report on Apple whether true or false because it brings more hits.
    Amd by "others" I meant other people on iPads - not other devices/manufacturers.  It's possible to do so, I just want to know how.  I honestly don't think we'll ever be in a Post-PC era until all tablets allow us to use USB in the way computers do.
    No, USB is not the future, you missed the memo about cloud and wireless computing?

  • Suddenly can't write to an external hard drive that I have been using consistently

    I have been using a WD 1 terabyte external hard drive to transfer movie files between 2 MBP's and suddenly I cannot write any files to the HD.  The error message is that the external hard "cannot be modified" if I try to add any files.  I have tried the same hard drive on another MBP and it works fine and I can write to the hard drive (with the aid of Paragon NTFS for Mac OS).  I have Paragon NTFS on my computer as well and have been able to write to the hard drive previously. I spoke to Western Digital phone support and told them the problem and noted that the icon for the hard drive is grey with a clock on my computer and is orange on the other MBP.  They explained that the icon change was due to Time Machine on my computer.  I currently have Time Machine turned off.
    Of note, I recently upgraded my internal hard drive on my computer to a WD 500 GB internal drive.  Not sure if this will make a difference.  Any help would be appreciated. Thanks,

    Found the issue.  When I changed the internal hard drive, most softward transferred over, but not all.  I had to reinstall the Paragon NTFS and I was then able to write to the external hard drive.  That seemed to solve the problem.

  • How can i format my external hard drive to write files from Mac without loosing the files that i alredy have on my external hard when i used it with windows?

    I have been using Windows to write files to my 1TB WD external hard drive and I do not want to format to loose the files capacity of around 500GB
    Someone, Please help

    Hi Allen,
    Is there any way to store the back up to Mac and restore after formating?

  • External SATA Drive

    Do Macbook Pros have external SATA drives? I have the first build of the Macbook Pro. Thanks.

    Your original post was a little unclear.
    Cardbus won't work. That's basically PCMCIA - which is no longer on the machines.
    For a MacBook Pro you need an Express Card 34 such as these;
    http://eshop.macsales.com/search/expresscard+34esata
    Then you can attach a drive to it. Take a look at the hard drives on the same site, they're quite good. They also sell enclosures you can insert a drive into so you could buy a hard drive from elsewhere, put it into an enclosure and then and then connect using esata - that will also work.
    Best of luck.

  • I would like to know if you have to back up a macbook hard drive, can I use a external hard drive that has been previously used to back up several pc 's, or is it best to have a separate external drive for the Mac?

    I would like to know if you have to back up a macbook hard drive, can I use a external hard drive that has been previously used to back up several pc 's, or is it best to have a separate external drive for the Mac?

    In the Mac side of things, backups usually come in two flavors: clones or incrementals.
    A bootable clone is a bit-for-bit copy of all essential files in the startup volume. If using the Lions, clones can be made using CarbonCopyCloner or just plain old Disk Utility. These backups represent the safest protection of your info, but take the longest to do. Recovery is an inverse process: you copy the clone back into the internal drive.
    Incremental backups start with a complete backup of the startup volume and only copy whatever changed from the previous run. OS X includes the fully integrated Time Machine backup utility to do this. It is extremely easy to do and takes the least amount of time. Recovery is another matter altogether since you have to start with a freshly installed instance of the OS and have to apply all intervening backups to bring the result to the latest saved version.
    As for where the backup takes place, the recommended media is an external dedicated drive or drives connected via the fastest interface available on your Mac: Thunderbolt, USB3, Firewire, or USB2. Network-based backups, wired or wireless, are attractive but may not offer the same performance and hence take longer. Also important to note that the entire drive need not be completely dedicated to a single backup. The Mac's EFI firmware infrastructure allows for an unlimited number of partitions on a hard drive and each can be used for either type of backups.
    Holler if you need specifics on how to do each. This was just an executive summary.

  • I do not have permission to write in my external Hard Drive

    Hello everybody.
    I have recently bought a MacBook Pro (15, 2.16 Ghz with OS X 10.4.9) and I have a Beyond Micro 300Gb external Hard drive that I have been using with my PC. This drive has a Windows NT File System.
    When I first plugged it to the Mac, I changed its name to recognize it better. Now, I am not able to transfer documents from my Mac to it, but I am able to do so through the PC.
    Am I done something wrong?
    Am I blocked this drive? (Once open, I see a pen crossed on the lower left corner)
    And if so, Could I unblocked it to make it writable?
    When I try to transfer any documents with the Mac I get a message saying that I can't do it and because I do not have permission. (I am the administrator).
    I read a previous posting talking about a similar problem, but I really couldn't understand the solutions and/or differences beteween NTFS, FAT 32, MS-DOS and MacFuse (I am a complete novice).
    I also tried (as suggested in the posting) to use the Disk Utility to set the permissions from there, but when I select the external Hard Drive all the options are dimmed. Also, the info panel says I only have permissions to write, having no other available alternatives to choose from.
    The question is: How can I make this drive available to both Operating Systmes without erasing all the information inside (format)?
    Thank You in advance.

    I have just intalled MacFuse (with Tools and Core) and it does allow me now to read and write in my external Hard Drive.
    Once again, THANK YOU VERY MUCH.
    And yes guys, this seems to work. Forget about formatting your external hard drive. MacFuse changes the permission instantly.

  • I can't see my external hard drive in the event library.

    I need to move my Imovie to a external hard drive to free up space.
    I can not view the external hard drives in the Event libary of Imovie.
    I have formated the hard drive to mac os
    PLEASE help urgent

    Strange if the drive format is Mac extended (journalled).  (see:  http://help.apple.com/imovie/#mov3ac6d42c)
    Can you can see the external drive in the finder? 
    Can you read to and write from it with the finder?
    Have you tried Trashing the iMovie preferences file and re-launching?
    Geoff,

  • Can I use my external hard drive for additional storage on my ipad?

    can I use my external hard drive for additional storage on my ipad

    With the Camera Connection Kit you can input data from an external USB device to the iPad, but you cannot write from the iPad to the connected drive.

  • I have 1 gb of memory with10.6.8 and want to upgrade my OS can i use an external hard drive to solve this

    I am running 10.6.8 and have 1gb of memory and want to upgrade can i use an external hard drive to solve this problem

    You are confusing RAM (Ramdom Access Memory) with hard drive storage space.
    You need to install more RAM, not an additonal hard drive.
    You can purchase an external hard drive, if you like, if you want to install the new OS X upgrade onto an external drive. If you want to run the new OS X Mavericks from the external drive, depending on your Mac model, you need a fast protocol external hard drive.
    Either a USB 3.0, Thunderbolt or FireWire 800 connected external hard drive.
    To start, if you are running your Mac on 10.6.8 Snow Leopard, this is the barest of RAM to run Snow Leopard.
    Without knowing any of your Macs specs, you realistically should be running your current OS with, at least 4 GBs of RAM.
    Newer versions of OS X need, at least, 4 GBs of RAM or more as these newer OS X versions use more Mac computer resources than earlier OS X versions.
    What year, screen size, CPU speed and amount of RAM installed in your Mac?
    Be aware, if your Mac is running any older software that used to run under older PowerPC model Macs, those software apps will no longer will work under newer versions of OS X.
    The emulation software that allows older PowerPC apps to run under OS X 10.6 Snow Leopard, called, Rosetta, no longer exists in newer versions of OS X and is long dead.
    Correct and reliable Mac RAM can be purchased from online Mac RAM sources Crucial memory or OWC (macsales.com).
    Good Luck!

  • Can I reimage an external hard drive that is in the windows NT file format?

    can I reimage an external hard drive that is in the windows NT file format?

    With WinClone 3.x $20 for Mac or with Windows imaging - built into Windows.
    Some like Acronis didn't (may now) work on Macs. Many use a linux CD recovery boot..
    You can write to NTFS with a simple NTFS driver. There, I strongly recommend Paragon for OS X
    www.paragon-software.com
    They also have all the program and Apple Boot Camp support
    Image a system or image a hard drive or.... ?

  • 10.5.8 to 10.6  Can I use an internal SATA drive in my MacPro for back up..

    10.5.8 to 10.6 Can I use an INTERNAL SATA drive in my MacPro for back up..
    or must I use an External hard dive.
    I prefer to use an internal for anti "desk-clutter" purposes. I am looking
    at a 2TB drive to install into my Mac Pro tower for the purpose of back up
    and time machine i guess.
    Also.. if doing a clean install of 10.6 how do i restore the backed up apps
    without re-registering all of them?

    A clone is a functional copy of the original, including the internal links & setting that makes it bootable if the original is. Time Machine will not make a clone of a volume, nor will a Finder copy. You can make a clone with the appropriate settings in the "Restore" tab of Disk Utility but many users find purpose-designed cloning utilities easier & simpler to use. The two most popular of these are SuperDuper! & Carbon Copy Cloner. Both are very reliable, easy to use, & well documented.
    I prefer SuperDuper! for reasons that are not important here. However, even if you decide to use CCC, I suggest that you download SuperDuper! just to read the extensive documentation that comes with it.
