Hardware :: Cannot Read External HD When Plugged In
Apr 11, 2010
I've got a simpletech 2tb hard drive which I've used for time machine, but all of a sudden it won't read when I plug it in. I can hear it power on when I plug it in but it won't show up. I've tried plugging in other devices to make sure the ports are still good and tried restarting with and without the hard drive plugged in. I've only had this hard drive a week and haven't done any improper device removals to it. Also, I am running snow leopard with all the updates.

I have this gorgeous 22" ACD that I have plugged into my G5, where I use it quite often. But my intention for the G5 was to be a server, which it is. I often need some extra display space when I'm doing school work, or coding, so I was wondering if there is a way that I can use the display, while plugged in to the G5, as an external display for my MBP. Preferably something that I could stream over my local network.

I'm running SL. I have a MBA, an iMac, and a LaCie external drive. I want to plug the MBA into the USB port on the external drive and the iMac into one of the Firewire 800 ports on the external drive. (On the LaCie, I have two backup partitions for each of the computers -- one for ? backups and one for a CarbonCopy clone of the computers.) When I connect them this way, the iMac can see the drive, but the MBA can't. The MBA will see the drive only if I unplug the iMac from the drive. Is there some sort of trick for getting both computers to see the drive at once? I don't care if they see all four partitions; I'd just like the MBA to be able to see "its" TM and CCC partitions on the LaCie and the iMac to see "its" partitions.

Is leaving it in ok as I erase my hard drive, and install snow leopard? How can I guarantee that my external hard drive won't be erased?

I've noticed a faint buzzing sound through my external speakers when a charger is plugged in to the laptop. Removing the charge kills the noise and makes the sound crystal clear again. Doesn't bother me to much, but as my uni-macbook pro is plugged in most of the time I can see this near constant buzz getting on my nerves a bit in the future. Any ideas, looking back I experienced the same thing with my macbook.

I have put contents of an external hard drive in the trash but not yet deleted them. How do I remove them from the trash (not delete them) as every time I plug the hard drive into the Macbook pro they show up in the trash again. I do not want them deleted.

MacBook Pro, Mac OS X (10.6.8)

I recently bought a new Mac mini and Seagate goflex 3TB external hard drive. The computer is awesome but if I have the external hard drive plugged in, it messes with the restart/shutdown. The mac will act like it's powering down and go to the blank white screen but will never turn off and shows the little gray lines that go in that circular motion at the bottom of the screen. If I disconnect the USB from the Mac then it completes its power down. I've tried the suggestions of repairing disks or disk permissions, as well as resetting the PRAM, which have worked sometimes but the the problem reoccurs. I've also tried ejecting the external hard drive before shutting down on the Mac but I'll either get an error message or nothing happens and then the above shutdown issue occurs.Â
Why does this happen and what can I do so that I can always have the external plugged in and not have to manually unplug it so the Mac can shutdown?Â

I have to have my hard drive replaced on my Macbook Pro. I bought an external hard drive (Buffalo) plugged it in and nothing no pop ups for instructions. Does a new hard drive (external) need something done to it on first time use?

I don't know if anyone knows what I'm talking about, but in OS X, there's this option that disables input from the trackpad when an external mouse is plugged in. I couldn't find something similar to that for Windows, and since I use Boot Camp to play a few games in Windows and my palms keep swiping the corners of the trackpad (thereby making my aim wonky) I wanted something that would have the same effect.
So I Googled. And searched. And searched.
Best solution was to go to Control Panel and disable the mouse. But I'm lazy, I want something to do it for me, automatically, if possible.
So, in the interest of pure laziness, I... wrote a utility to do pretty much exactly that. It supports manually enabling or disabling the trackpad, and also automatically enabling and disabling it when an external mouse is plugged in/removed.
URL
So, if any of you guys are using Windows to play games or do anything else, and you have the same issue with the trackpad that I do, hopefully this helps you guys out too.
If not, well, thanks for reading and I'm jealous of your smaller palms and/or dexterous avoidance of palm/trackpad slippage!
Note: Still might be bugs and things. Feedback appreciated, but constructively, of course.

We have an iMac G5 running 10.4.11 which developed some nasty colour banding down the screen and have now plugged in an external display. How can you turn off the iMac display so it only outputs through the external monitor?

I have a white plastic macbook which appears not to be able to connect to my wireless network. All the other PCs and a Mac Mini in the house connect fine, but the macbook does not.It has connected since i got it, both to the home network and a network in school, but today it promted me for the wireless password, connected a few times but did not give me a IP address, and now will not connect at all! The network appears in the list, i click on it, enter the wireless password, then it says connecting before connection failed.
The network setup is a Cisco router connected to the modem and then connected to the wireless too. There are no computers connected via cable to the network.

My boss just gave me a MBP Core I7 2,66Ghz / 4GB Ram, model mid-2010 for the business. It is equipped with Nvidia GeForce GT330M as PCIe video card. If I plug an external monitor, I have, after some time between minutes or hours of work, a weird video problem, which obliged me to power off/on the MBP. Sometimes I even can see my mouse moving, but I can't do anything with it. If I do not use the external monitor I do not have problem. This type of problem appears around 3-4 times a day and make the MBP unusable, as I'm loosing the recent work each time the problem occurred.
Here is the extract of the console at the time of the crash :13/03/12 16:45:51,203com.apple.kextcache/: no supported helper partitions to update.13/03/12 16:47:29,000kernelNVDA(CopyEngine): Channel exception! exception type = 0x27 = CE0:

The problem seems related to NVidia GPU. I've reinstalled everything from scratch without success.

My Macbook runs with Mavericks and I can't access to a folder which is shared on a external HD plugged to a PC with windows XP. That was possible with my old Macbook with 10.5.
For the shared folders which are in the internal HD of the PC, no problem.Â
I precise that I would like accessing with the "Shared" menu in Finder sidebar. If I use "Connect to Server", I'm able to see in the folder, but not to open the "children folders", excepted if I reuse "Connect to Server", by complementing the path, etc

I have an external Transcend HD, which has been working perfectly fine for around 5 months now. It is NTFS, and I use NTFS-3g and Macfuse. Been running fine. Was able to read and write. Suddenly I am only able to read though. I go into the "Get Info" pane and the option to choose whether I want to read and write, or read only is gone, and all that it says is "You can read only". getting this back to read and write is really appreciated. I really need this disk.

I upgraded the ram to 4gb crucial on my 24" intel imac (early 2008). Now it freezes at apple screen, but only if my external WD My Book hard drive is plugged in via firewire. If I unplug it from the firewire port.

I use my MBP 15" (the new one), as my primary machine in my office. I sit by my best usually 10-12hrs a day working on it.
I am trying to figure out what is best to do, keep the AC plugged in or have it un-plugged and only plug it in when the battery is drained (or less then 50%)? I have tried different experiments, plugged in, not-plugged and time is about the same for life of the battery. The true question is, how is is best to do it for the health of the battery.

So my entire iTunes library (about 200 GB) is on an external HD.
After I installed Leopard it's showing as Read Only. There is not option for permissions and in Disk Utility all I can do is verify the disk.
Obviously I can't delete or add files or do anything but read them.

I got a macbook pro and a My Book 1tb. Want to finally put away my old PC (which is running only on UBUNTU) away but I need to get the files off my PC onto the My Book. Well after setting up the time machine and what not I move the HD & connect it to my PC & attempt to drag files onto it. Says it's read only. Tried changing the sharing options to read and write for everyone on my mac. Still the same. Used disk utility to wipe clean the entire HD. Still read only. Posting this on Ubuntu forums but I'm positive the problem is on the Mac.

i have a sony vaio external hard drive, and i formatted it using my PC, and it worked perfectly fine - i can read / write files to the HD.
however, it was shown as a 'read only' HD once i plugged it to my Mac.. i even tried it with my friend's Mac and the same thing showed.
i tried to repeat the formatting and plugging with both my PC and Mac over 10x time and it's only giving me the same result.
does that mean my mac is not compatible with the HD?

I recently purchased this external hard drive. I transferred several GB of movies/TV shows/music onto it from a Windows 7 PC. Now that I've hooked it up to my Macbook (10.6.2), it shows up as read only.

I am sure this is a simple question, but I am having a problem going from windows to mac with an external hard drive. I can read and write to the drive on any windows PC. On my macbook pro laptop, I can only read. It will not let me write or erase anything to the drive. Does this have to do with the drives formatting? If so which format will let me both read and write on mac and pc?

Before you peek into this topic to say "OS X can only read NTFS, not write to it", save the effort; I already know that. I have a 1TB WD MyBook Studio. I partitioned this drive into 2 parts, an Mac OS Extended partition and, using Win 7, an NTFS partition. Now my MBP can mount and see its partition just fine, but it refuses to mount the other NTFS partition, seeing it in Disk Utility as MS-DOS (Fat) format with a weird name. How do I get the MBP to mount the NTFS partition?

Every time I reboot my computer my external drives are all set to "read only". I have to eject them, and remount them and things are then fine again, but this is an annoying step and the fact that a reboot is causing them to switch to read-only is having me worried.
Anyone else have this problem/know of a solution?
I've been trying to figure it out over at the official apple forums but we're not getting anywhere... the thread is here:

I bought an Iomega Prestige 1TB external harddrive a couple months ago with it running off my Macbook Pro.
I just flew down home for spring break, leaving my Macbook Pro charger at school. However, I do have the harddrive with all my backed up files. The problem is, my PC laptop (Dell, Windows XP) does not recognizes it. When I plug in the harddrive and turn it on, the computer recognizes that there is something plugged in (it gives me the option to safely remove hardware), but there is no sign of the drive anywhere.
Is there anyway my PC can read/recognize it?
