Recently my computer has been slow, having freezes, endless colorwheel/beachball, etc. I've deleted the whole disc and rewrited 0s to it, which fixed a bad sector error and seemed to help but its still freezes oftenly. I have come to the point where I think the HDD needs to be replaced and theres nothing else I can do.

Ok so I have an 8800 GS imac, 3.06 intel core 2, 4 gigs ram. Running snow lepord. I need to resolve an issue where I can not get into OSX. At first I got error messeges saying my external HDD could not read, now it looks like its my primary drive because when I restarted I got the progress bar under the apple logo, indicating that something is wrong with the OS. The bar when to full 100% but then I got stuck at never ending spinning wheel. I restarted and no more progress bar but still the spining wheel of death. I really dont mind refomrating its just that I had some important text documents and other files that I cant get back without recoving them some how. How to proceed? I held down cmd v or s (i forgot) on startup and got a black screen with several problem statements. One reads the system boot strapper has crashed trace BPT trap.

I have all of a sudden started getting an error code -36 from an CF card copying to my mac?

I have a late 2006 iMac, which I know must be at the end of its life now, but at the weekend my main internal HD developed an error, and it wouldn't boot, even from the recovery partition.Â
I managed to find my old Snow Leapard disks and ran Disk Utility on my HD (when it actually saw it) and the error it came back with was "Invalid Node". After trying many things, I had to reformat and reinstall from my Time Machine back up, which went really well.Â
However, once all restored it tried to do a backup and it failed. I then went into Disk Utility again and it found the same error on the Time Machine drive.Â
Therefore, my question is, could the back up process have copied an 'error' to my back up? Or is this a fault somewhere else (Disk Management etc) that I need to watch in case it cases errors with my other drives that have important information on?Â

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?
View 4 Replies View RelatedMy Macbook Pro suddenly won't read my 750GB WD Elements Hard drive.It was working earlier today but when I went to press play on my TV show in VLC it said the files couldn't be read. So i reopended them all and they still didn't work. I closed down all programs running that could possibly be using my hard drive but it said it was being used so I force ejected it and when I plugged it back in it didn't work.
It comes up with an error message "this disk can't be read by this computer" but it still shows up in disk utility. In disk utility though it says it is a 2.2TB hard drive which confuses me. also I the buttons for "verify disk" and "repair disk" are greyed out.

For some reason my Lacie external drive that's hooked up to my imac is constantly being read for no reason. It's never idle and never rests until I eject it. I'm afraid the drive's gonna fail soon and all my work gone? Did a search but can't find anything online.

After repairing the processor and installing and updating os X 10.4 on a 20g drive I added and additional 100g drive for music and videos. The 20g drive read/write is fine and writing to the 100g works fine also. When attempting to view videos located on the 100g drive, the system hangs. when using itunes it must rebuffer every few seconds.
View 5 Replies View RelatedI 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 bought a Seagate Free Agent Go Flex External drive. I transferred all my files from my previous external HD.
When I went to access my folders on my external HD, the folders are all locked, with Sharing and Permission section in the Information "Everyone: Read" only! I can't change any of the information or move things! All of them are locked and "read only." I know how to change it, but only manually, individually. I have several hundreds of folders and I don't want to manually change all of them to "Read & Write." Is their a way to let me re-set the folders to "Read & Write" easily??
I'm both elated and pissy at the same time. Something happened to my mac when I was traveling, be it a latent hardware flaw, damage, or some other random act, and my mac OSX partition just, well, died. Unbootable, disk utility spends over a day trying to fix the boot record. The Bootcamp windows partition is fritzy, but it at least mounts and periodically can be booted from. I bought an external usb hard drive, loaded SL onto that, and have my mac back up and running again, but no data to speak of. So based on numerous recommendations, I paid good money to purchase Disk Warrior 4. Nothing, just told me the Macintosh HD partition on the hard drive was damaged, but that bootcamp could still be read.

But there is nothing there but a greyed out : You can only read
There are No boxes to check or uncheck, No options to change to read and write, No name of owner or ignore ownership box. NOTHING ELSE IS THERE

I have just installed a new hard drive in my imac intel 20" (2006) and upgraded the memory and now the hard drive does not show up in the 'select destinations' folder of the install program. I can see the hard drive in the disk utilities window however it wont let me do anything.It is a seagate 1TB SATA II drive however it is displaying it as a 7.3 TB.I have tried to erase and partition and get the same error message each time, 'Input/Output error'.
I have tried starting the thing with the install disk which is Mac OS X (Tiger?) which came with the computer

It reads commercial CD's fine but any CDR shows up as a blank CD. This happens with multiple brands and the CDR's play in a car stereo and are read by other computers. I can burn blank CDR's just fine. The problem is recognizing the content once they have been burned. I have seen this issue posted as far back as 2008 on some boards but no solutions other than replace the superdrive. I find it hard to believe that I would have a bad drive already given Apple's reputation for great products and the age of my computer especially since the warranty just expired in October.

I have a problem with creating disk partition via Bootcamp Assistant. when i try to run it i get an error message saying "some files could not be moved" and the process of creation is aborted. I have sufficient free space of 50GB, trying to create 32GB win XP partition. Some freeware utils confirmed that my th data writtne on my HDD are very fragemented (and so is the freespace). I'd like to create a compact data area (wich would result in creatin a compact free space area).
so far i've found 2 ways:
1) Backup my HDD, reinstal OS , crate a fresh partition and than copy the backuped fiels back - unfortunalty i don't have a backup drive
2) use iDefrag (a payed 3rd party utility) - unfortunalty this one has very limited usage on mounted disk, and so it has a little/no efect on my hard drive fom which i boot the system, and i don't have a second drive to boot from
So my mac's hard drive went out. So I bought a new one that is 160GB. I'm trying to partition it in Disk Utility, but there are a couple of problems I've run into. First, It's saying there is 1.2TB of space. I guess it's possible Western Digital put a wrong label on their drive, but that seems a bit unlikely, doesn't it? The second issue is that when I go to actually partition it, I get an error that says, "Partition failed with the error: input/output error". I have no idea what's going on, or what I should do
I'm using a Macbook w/ 10.4.11 (although strangely, that disk that came with my computer says 10.4.9, not sure how much of a difference that will make...). It is a 2.16GHz, Intel Core 2 Duo, w/ 1GB of ram, if it helps.
Also, when I'm trying to partition, the settings I'm using are:
1 Partition, Formatted w/ Mac OS Extended (Journaled), & GUID Partition Table

View 1 Replies View RelatedThe last couple of times I have woken my MBP up a box has popped up with a big red sign in the middle saying my external hard drive was removed unexpectedly and could have caused loss of data. I know this is not healthy and I would like to stop it doing this as soon as possible. It is connected via firewire 800 and is a western digital 250 gig my book pro if that makes any difference. I close the lid of my laptop with it still on and connected and everything is supposed to sleep. It used to work fine, I would open the lid and everything would wake up and I could do what I was doing before with no error messages and the hard drive would still be mounted on the desktop.
View 7 Replies View RelatedI have a USB 2.0 hard drive that I have been using to back up movie files. It has let me transfer files from my Macbook Pro HD to it hundreds of times without any problems.
I have this .mkv file that keeps giving me an error when I try to transfer it to my external. I get "Sorry, the operation could not be completed because an unexpected error occurred. (Error code 0)".
I have transferred plenty of .mkv files to my external with no problems. All other files work fine when I transfer them. It will let me move my .mkv file around my Macbook Pro's internal hard drive but it won't let me transfer it to the external.
I am trying to do an archive and Install of OS X Leopard on a MBP but the installer won't allow me to do this.
I have tried the install by holding down the Option Key at bootup with the Leopard DVD in the drive. I follow all the options and then try to do an Archive and Install but when it gets to the screen with the Hard Drive icon it shows the Hard Drive icon with the Exclamation point in the yellow color. If I select options it tells me I have to erase the hard drive and do a fresh install of OS X.
I have also tried the install by booting into OS X and then selecting the OS X DVD icon and going through the same steps.
I have used Disk Utility and done both a verify and verify permissions but no errors at all are found. One odd issue is when I hold down the Option key at bootup it actually lists my internal hard drive twice. It appears everything is fine. Disk Utility finds now errors, shows it has the GUID partition table, and is formatted with OS X Journaled.
What started all of this is a couple weeks ago I started having Wi-Fi issues. Anywhere I connect to Wi-Fi it connects with the signal but I don't have internet. I'm not able to use Firefox, Safari, or Apple Mail. I posted earlier about this but was unable to fix this problem so eventually went to the Apple Genius Bar. They thought it was a simple issue and tried a couple procedures to renew IP or something like that and restoring some files. After none of that worked the guy then said it's something deeper in the OS and a Archive & Install is the best way to solve it.
When he tried this though it didn't work. He did a Verify in Disk Utility and found some hard drive errors so corrected them. Once this was done he did another Archive & Install and ran into the same problems I encountered.
Of course I'm still having this issue. His suggestion was to do the erase and said to first plug in my Time Machine Hard Drive, Do a Backup now, do the erase on the Hard Drive and reinstall Leopard, then he said Time Machine should prompt me to restore or something like that and will copy over all my stuff, documents, itunes music, dock settings, desktop, etc. Basically everything to put my computer back to where it was before. Now I do have a SuperDuper backup but since this is a mirror of the internal hard drive he said it would likely copy the problem back to my internal hard drive.
Is there a way to possibly do an archive & install? I prefer to go this route but don't know why it won't let me do it. If not, would the above suggested option with Time Machine solve this problem and would I lose any settings or data?
Another option I may try is I have Leopard on the Machine but have bought Snow Leopard. I haven't done the upgrade because one program I have, PGP, is not Snow Loepard compatible until the next version comes out. Since I haven't used PGP yet if necessary I am willing to uninstall it and install Snow Leopard but i'm not sure if the Snow Leopard upgrade will work and solve the Wi-Fi issue.
I have a 150gb Raptor running Windows XP on my MacPro and unfortunately it'll no longer mount on the desktop. When tested with TechTool Pro and Drive Genius, the drive is recognised but in both instances the volume didn't show. Exactly the same happened with Disk Utility and the System Profiler. I've spoken with Apple and their recomendation is to re-initialise the drive which I really don't want to do as stupidly I dont have a back-up
