MacBook Pro :: Internal Hard Drive - Reading Ok But Cannot Write
Mar 12, 2012
I have a late 2009 MacBook pro, running the latest version of Lion. Last week, I experienced a Kernel panic at start up, and was unable to launch the OS, even with the recovery boot. Starting in verbose told me that there was a sata issue. I opened the computer, replaced the internal hard drive with lion set upon it, and tried to start again, without any success. I bought a SATA-USB cable to plug my old hard drive. My computer is now running normally, but with the former internal hard drive plugged in USB.
Disk manager sees the new one and I can read data written upon it, but I can't write anything nor erase or partition it. So both the hard drives are OK (I tested them in a friend's MacBook pro and it worked), the computer seems OK too, because I'm running it presently, but any internal hard drive won't work. The cable that links the hard drive to the motherboard does not seem to be damaged, however, the status indicator light is not working since that time.
How do I transfer all data from my old internal hard drive to a new internal hard drive? I have an iMac with a 320gb internal HD that is full and I am replacing it with a 2tb internal drive. I have several external drives; 1 tb, 2tb and 3 tb. The 2 tb is being used for Time Machine. Do I have to buy an enclosure? If so, where would I get an inexpensive one? I also want to partition the new internal drive for Windows, and I'm not sure how much space to use for that. I plan to use Windows to check my work in PowerPoint created on my Mac for clients on PCs.
How do I change permission for writing to my usb harddrive that was previously used on a windows pc. At present it will not let me write and in the top of the window there is a pen which is crossed out.
Basically, my friend got his new MacBook Alu for Christmas, but currently all the hard disk is doing is reading constantly, even when he has nothing running.
I bought a MacBook Pro 13"".I do have a seagate external hard drive. When i connect my External Harddrive to Mac the data can only be read mode.I am not able to Write data on to External Hard drive.
I recently borrowed my brother's laptop to use as a media station for listening to music from, and watching movies, in order to free up some space on my main macbook. In trying to migrate some files over, I discovered that my hard drive, a 320 GB WD Elements drive, is having some problems which I've never encountered before. It has always worked fine in the past, but now I can't transfer any files to or from it, from either computer. In all of my troubleshooting, I've gotten various errors, (-36, -50), and various messages saying how the device can't be read or written from, or how some files contian unreadable data, etc.Disk Utility found an unused node when verifying the disk, and notified me that the disk needed to be repaired.I then used Disk Utility, which said it was able to successfully repair it, but the same problem remains, and after verifying the disk, it still says it needs to be repaired.I've tried to find any files that may be causing the problem, and was finally able to delete a seemingly troublesome file that was stuck in my trash bin from the external drive after trying various apps, (ie Trash It, Cocktail, What's Keeping Me?).This didn't end up solving anything...I've used terminal to eliminate some other potentially problematic files, with no luck still, and I'm not too confident with Terminal so I don't want to be messing around too much without more guidance.
I've used Disk Warrior to try to solve the problem, but still with no success.When I use the app to Check All Files and Folders, it does so for only a few seconds, then reports that "An unexpected error ocurred while attempting to perform file operations" for several files, and that several files' "Property list is damaged and cannot be repaired". When using Disk Warrior to REBUILD the drive, the app pauses for about 15 seconds, then says that it can't be rebuilt because it is in use.Again, I've used the What's Keeping Me? app to kill any activity with the drive, and the same error occurs.I've spent a lot of time trying to sort this out.
I just removed my Windows 7 using Bootcamp, since it wouldn't start up properly anymore. The thing is, there was this error in Bootcamp while uninstalling Windows. I wasn't able to read all of what the error was, so I removed the Windows again, or at least that's what the Mac seemed to be doing, until it got stuck somewhere for a suspiciously long time. I forced quit it, which might've been a bad move. So anyway, when I checked Bootcamp again, the option for removing Windows wasn't there anymore, so I assumed all is well. Until I saw the storage and Diskutility."
I did Verify Disk and Repair Disk before the last image. As you can see, the disk appears to be OK. But obviously it's not. The Windows 7 I had seems to have been uninstalled, since I can't find it in the selection part when pressing "alt" while turning it on.
I have a Late 09 15" MBP and a WD 1TB external HD. I've never had a problem until now. I start up the hard drive, then it loads up fine and the Mac recognizes it just fine. As soon as I try to copy something - doesn't matter how big it is - I get an error and at the end it says "(Error code - 36)". It just says the file cannot be read or written. Weird thing is I can access everything on the hard drive. Anyone have any tips before I try reformatting the HD?
My external hard drive was accidentally unplugged without ejecting. Now when I plug it in, it read only. I can copy files from it but not to it. Is there a way to reinstate write access without losing my data?
I have an early 2009 macbook, with 320 GB hard drive and running OS Lion, after i upgraded my os to lion, the computer ran perfectly normal, although a little bit slower than running snow Leopard. However, recently I notice my mac become very slow, got rainbow wheel even when i open the safari. then I use the black magic to test the hard disk speed, it appears the read and write speed is only a little over 30mb/s.
i have recently change my keyboard at apple store, I notice my mac slow down after that, do you think it would related?
I have an external hard drive(seagate 250 NTFS format) which i have used on my windows 7 computer now that i'm trying to load the information onto my macbook pro (10.7.4) it will not let me change the permissions nor duplicate the files. How can I be able to edit and save the information to my mac from the external drive??
Starting today, when I try and write anything to my non-OS harddrive (with my music library and data on it), OSX gives me the error: "The data can't be read or written" The permissions seem to be fine. I can open files on the HD fine, but they open a little slow. So basically I only can't write to the drive. What's going on? Is my HD dying?
Furthermore, I cannot do anything write-related anymore, no deletion of files in the Finder, no opening of webpages. Eventually, I have to force shut it down by holding the power button.
I already wiped the HDD and reinstalled Mavericks from USB -- only to have this exact problem one day after setting everything up again. I even bought a new HDD, which worked quite well for a couple of days, only to result in the same error again.

Can I add a second hard drive to my MacBook Pro 4.1, 17 " dual core? I have a 250 g. hard drive installed and it's filling up. I also have various EXTERNAL drives that I use but am interested in the possibility of a second INTERNAL one.
sorry if this is a noob question, but when I try to save things to my new external hard drive a box comes up telling me that the disk is write-protected. Is there a way I can write-enable it? I have tried a bit of searching on Google, but to no avail.
I recently bought an external hard drive (like 2 weeks ago)- I put two partitions on it, one set as a Time Machine backup (HFS+) and one as file storage (FAT32 to make compatible with Windows XP boot on my Macbook Pro). When I first got it, I remember being surprised by how quiet it was. I filled it up and now, whenever I plug the drive in, it makes a sound like it's constantly reading (reminds me of the sound old, old computers used to make when thinking a lot, i.e. with the blinking orange light).
As soon as I start 'using' it (for instance, turning Time Machine backup on, etc.) it suddenly starts running quiet again. I made sure to make it 'invisible' to Spotlight so it doesn't index the drive... what else could be accessing the drive and making it work so hard? The constant 'grinding' of the drive is really bothersome!
i had a External Harddrive.Currently i can Read//Write on it in Windows PC(Windows7)But when i use the same drive in Mac i can only read...but can't able to write. How to resolve this issue
I got a new 1tb WD internal hard drive and I took it out of the box and popped it right into my macbook pro 15". It fits and i am able to easily close the back on the computer. My only problem is that when i start up the computer, it loads for a few minutes, but 100% of the time after about 3-4 minutes i get a notice saying I did not eject the drive safely and all that. After that the internal hard drive is no longer there. I cant see it in my finder, or disk utility. BTW I am booting from my old hard drive externally. What would cause the new internal hard drive to eject itself?
I have a 64gb ssd drive that I use to boot up my macbook pro 15(classic) and a 320 gb on my optibay. I would like to know if there is such a program like smc fan control but for internal hard drives in order to turn off or "PARK" the 320gb hd, This would help increase my battery live as well as making it more quiet.
I recently put a new internal hard drive in my macbook, but i need the bolts that help stable it. do you know what these screws/bolts are called and where i can purchase them? also, i tried using a t6 screwdriver to remove the same things off the hard drive that was originally in my computer, but they wouldn't budge. it was as if they were already stripped before i tried taking them off. is there a "safe" way to remove these with something else, because it doesn't fit in the enclosure i bought with those dumb bolts on it.
My internal hard drive is running out of space, and I want to buy a new one. But to do that, I'll have to buy a external hard drive to back up everything and then copy it back onto the new internal hard drive , right? I don't have that much budget. So can I use the old internal hard drive that I took out of my Macbook and copy everthing back into the new internal hard drive after the repalecment? so I don't need to buy a external hard drive to back up everything
What is the standard tool to test your hard drives read/write speeds? I'd like to test my new SSD to see how fast it really is. I've heard you cant trust XBench for that which is the only thing I have to use.
I have a Toshiba 250GB external hard drive to back up pictures. I can write to it just fine. I also have a Fantom Drive 1TB external. I could write to it last week, but I turned it on this week and I can't write to it. I can still pull stuff off of it, but I can't write to it. What can be causing this? I have already installed MacFuse and NTFS-3G. It doesn't make sense to me that I can't write to it all of the sudden.
After a lifetime of owning PC's I finally purchased a MacBook Pro running OS X. I installed Parallels Desktop 5, Windows XP, and several Windows apps to have dual functionality. Now I need to write to my NTFS ext. hard drive where I backup everything. It has 800gb of space left, so it would be a shame to get a new one just b/c I have a Mac now. I first installed MacFuse and then NTFS-3G. Now when I reboot, the ext. HD won't mount at all. What have I done wrong?
The one response I had was: 'alex try putting your mac os cd in and restart the system holding down the letter d key and let me know what happens.' unfortunately I can't find my system disc... will I need to buy a new one? here's a the problem: I have a PPC G5 iMac 2.1GHz, 1.5GB. The Internal Hard drive is 250GB in total and partitioned into 4 sections. After working fine for ages I suddenly found I can't copy files into one of the partitions. Initially I got an error message saying: "DS_store could not be tead or written. (Error code 36)" I used Disk Utility to clean up the hard drive. Which didn't help. Got a copy of Disk Warrior(4.1) to try a more effective clean up. There were a few errors that found and fixed, but i still got the same error message. Then found a utility called DS_Store Cleaner to try and force it to remake the DS_Store files. This got rd of the DS_Store message but I'm still left with another error 36 message and still unable to properly copy. The message then said: "The Finder cannot complete the operation because some data in "example file.doc" could not be read or written. (Error code -36).
I have also got hold of a copy of techtool pro (4.6.1) and run everything - basic, intermediate and advance scans. Everything (aside from a few minor errors on other partitions - which it cleared up easily) was fine, that partition showed no errors at all. I didn't do the full tests on the system partition though as I haven't used the e-drive function yet. The problem has been ongoing since late March.Just today I found the same problem in another of my partitions: "The Finder cannot complete the operation because some data in "example file.doc" could not be read or written. (Error code -36).This happens when trying to copy to either of those partitions or trying to save anything to either of them.What might be causing this and what should I do next? with the first partition to have problems I am unable to copy/write any file size (eg KB size files) with the most recent partition I found I could copy a 2.3MB Jpeg. The problem occured when I tried to copy a 680MB .mov file (there was enough space - about 1.8GB)
I just had the hard drive replaced in my IMac and it only at 1 to 1 or maybe 2 to 1 speed. my old one did over 10 to 1. car it be speeded up? Any way to get hard drive to read/ write faster?
