MacBook :: External Drive (RAID) Crashes Computer
Dec 31, 2009
I recently installed os 10.6 on my MacBook, upgraded to 10.6.2 and everything was still working fine. Then, without thinking, I ripped out my shuffle and plugged in my mirrored (software) raid array of 2 drives. I immediately got the dimmed screen / you must restart your computer in all languages-screen. Now, whenever I plug in the raid into the usb the computer's screen goes dim and I get the same error message in all languages. I've tried booting with the install disk, still crashes. I have all my most important files on that drive.

Unlocking my external hard drive crashes my computer. It was encrypted by Time Machine (and I think that means it used FileVault because the unlock window has the FileVault icon).
There's a prompt to unlock the hard drive as soon as I plug it in but when I press the Unlock button my computer crashes.
I've tried different user accounts, safe mode, disk utility, recovery mode, different USB cables and different USB ports all with the same problem. As soon as I press enter on the password prompt the system crashes. If I type the wrong password it denies me so I know the password is correct.
The drive is in a SATA to USB dock but unfortunately I don't have another one to test with. Other drives work just fine in this dock.
The data recovery software I tried is useless because all the data is encrypted .

I just had the original 300 GB hard drive fail in my aluminum 24" inch iMac running the latest update of Leopard. I wasn't able to save it using diskwarrior (diskwarrior said it was some sort of mechanical failure) but I was able to recover most of the data from it by booting from an external hard-drive.
So I went out and purchased a brand new Western Digital Caviar Black 1TB drive. The install went fine, it found the drive partitioned it and installed Leopard successful. Then is crashed and disappeared when I left it alone to run all the software updates. I came back and the computer was stuck on "Restart Required" after downloading all the updates. I went to hit restart now, and the system just hanged, wouldn't do anything. So I hard powered down the system and restarted it. It came up with nothing, just stuck on the White Screen of Death. So I plugged the external drive back in and booted from it. Mac OSX couldn't find the drive and diskwarrior would crash if I tried to run it. I tried to boot up from the OSX start-up disk and it couldn't find the drive either.
So I took the case apart and made sure all the connections were solid and the drive was mounted correctly. Everything looked fine so I plugged it in and it started up fine. Finished the updates and the iMac ran great.
So I thought maybe it was overheating, so I've installed smcfancontrol and started to monitor the temp of the drive. I also took the mac apart again and sucked out any dust in the fans or vents. The drive never goes over a 105 F, so it doesn't seem to be overheating.
However, this is where the problem is consistent: everytime the iMac goes into sleep mode, it crashes and the iMac is unable to find the hard-drive again. Unless I unplug it completely for 5 minutes or so. Once I unplug it, it finds the drive and operates like a champ.
I think maybe there's an issue powering the drive back on? Anyone have any ideas?
And my follow up posting later that day:
Quote:
So I ran some tests just to see if was an overheat issue, hard drive malfunction, or sleep issue. I decided to start encoding a video, pulled up Word, Power Point, Excel, started downloading all 6000 mail messages off my server (I never delete my e-mail :-/), also started installing iLife 09, and pulled up a bunch of webpages in Firefox with multiple tabs.
However, I shut off all sleep mode options on the hard drive. I let it run for an hour and came back. Everything is fine, hard drive isn't locked up and smcfancontrol shows the hard drive running pretty hot (115 degrees) but not so hot I'm worried. So it's definitely something to do the hard drives going into sleep mode and not powering back on. It's also weird that I have to leave the computer completely unplugged for 10-15 minutes before the drive is recognized again.
So turning off sleep seems to be my work-around, however, this shouldn't be a long term solution. I'm worried that there is a bigger issue with the iMac, but I'm not sure what would cause this. I've been a PC guy for years, this was my first Mac, and honestly I don't know enough about the inner workings to narrow this down. I would assume this would have to do with the motherboard in some way? But I'm not sure how you would even test it.

I have a PowerMac G5 and need to purchase an internal RAID card to create a RAID 1 mirror of the system drive... one that will allow me create a Hardware RAID 1 mirror, not software RAID through OS X.

wouldn't even load. It would just show the little blue "light" flashing on and off, as if Finder were launching, crashing, launching, crashing.After some deduction, I found the problem to be my USB WD hard drive. It used to previously work fine. It has only one partition on it, which is HFS+ formatted. Disk utility verify/repair reports that the drive is fine.

1. I plug in my 2.5" external hard drive. It appears in Finder. I can see the contents of the main directory. 2. The moment I CLICK on any folder/file, I get the beach ball and Finder crashes. This is the only time Finder crashes.I've searched the forums but all the results are old and no solutions have been found.

I have a RAID 0 set up with two 1.5TB HDs. I am doing some reorganizing and want to take all the data on the RAID 0 and move it to one of the hard drives in the RAID 0 and create to single drives. Is there any way of moving all the data from a RAID 0 onto one of the HDs?

when I insert my 'FAT' formatted external hard drive (Samsung M3) into my mac book pro it comes up with the error message that says "the inserted disk is not readable by this computer" and I therefore cannot access the files. The story (potential further details):
1. I had a problem with my mac where it took hours to load each time I turned it on, would only work when power was plugged in etc. so I had to reformat my mac hard drive (when I tried to veriify it said repair, that wouldn't work). So i'm starting with a recently reformatted, clean mac.
2. Before doing this I reformatted my external hard drive (whilst on windows machine) to FAT32 (so I can use on both windows and mac) so that I could back up my files.
3. I then transferred files from mac onto external hard drive and then also put them on a windows machine.
4. After reformatting mac hard drive when I then tried to transfer files back onto the mac I get the 'not readable' error.

My external hard drive has been repeatedly ejected improperly and now it is not displaying on my computer, not even in disk utility. How do I re-mount this external hard drive? In the past when this has happened, all I had to do was go to Disk Utility or use DiskWarrior to fix the issue but now it won't even show up in either of these apps.

I just bought a new 1 TB external hard drive for back up purposes. When i connect it via USB to my Snow Leopard macbook pro, it gives me a "this disk not readable by this computer message". I click ignore, and it lets me do whatever i want to the disk - read, write, etc. I have tried repair disk - tells me it's good to go, and tried reformatting several times - thought not zero disk data or the 7 pass bs.

I am thinking about buying a HD for a full system backup and all files. I am worried about getting such a big HD and having it fail, thus loosing years of data. Is there any redundancy in a 1TB drive does partitioning help? What if the entire drive fails or are there multiple drives in those external hd? I need a reliable backup system for music, photos of child, that will last years. I want to be able to use the HD with both formats, pc and mac...what should I format with or is that a good idea?

I have a macbook pro MAC OS x and have started having issues with my computer's screen going black while working in iphoto. The only thing I can do is to press the power button to power down and then reboot. My memory is fine on the computer. All updates have been completed. Best I can tell, this only occurs while using iphoto.

how to tell my macbook pro (tiger os x 10.4) to read my new Lacie external dvd/cd-burning drive in order to burn a dvd, rather than the current internal apple one (which came with the mac upon purchasing and recently went kaput)? btw, I CAN see this Lacie's name-path when I go into the apple-icon's "about this mac/more info". Then, I can see the lacie drive's name-path either by accessing the Hardware's option of "FireWire" or "Disc Burning".

I have an external hard drive that I have been using for back ups for several months, but now I get an error message that says, "The disk you inserted was not readable by this computer". I looked up other peoples issues with this, and they have used things like disk warrior to fix it, but I am not very interested in saving what's on the hard drive anyways. I just want to clear out the hard drive and start fresh.

I have a hard drive that I connect to my computer via an IDE to USB adapter. It works quite well, most of the time. A couple days ago I tried copying a large file to the drive (which is in FAT-16 I think) and the copy froze after 28 MB. The hard drive failed to eject, so I just disconnected it without ejecting. After I dismissed the device removal warning, I immediately plugged the HD back in and opened disk utility. I tried to reformat it, but the computer froze and my screen dimmed and the warning came up telling me to reboot in several different languages.
Now, whenever I plug in the hard drive, it is not acknowledged by the computer at all. I always end up unplugging it after a couple minutes. After I unplug it, a folder with the name of the drive (which happens to be "untitled") appears on the desktop, but I can't do anything with it. This folder is classified as a disk and it is acknowledged by Disk Utility. A couple minutes after I disconnect the HD, Mac OS X always quits and I have to reboot. How can I repair this hard drive? How can I get Disk Utility to acknowledge it?

I am looking to buy an external hard drive for my intel Mac and MacBook Pro to download and save some 8,000 plus photos. My computers only have USB 2 connections. I am finding that most new external hard drives have USB 3 connections. Can I use an external hard drive with a USB 3 connection on my older Mac computers? If so do I need an adapter to connect USB 3 to USB 2?

Everytime I start skype while in windows, the computer crashes and I get the blue screen... I think it has to do with the sound drivers, because when I'm using msn messenger also in windows suddenly the microphone mutes itself.
I tryed updating the realtek drivers with no help, updated skype, no help, I uninstalled the realtek drivers and the laptop did not crash anymore but I had no sound, any advice like for example how to get the microsoft drivers to work on the laptop without using realtek??
For whatever reason with the microsoft drivers,I think the sound is trying to come out of the digital outlet, I can see the ligth inside the jack, but nothing comes out of the laptop's speakers...
By the way, the vista version is Home basic.
