OS X :: External Hard Drive Error After Wake From Sleep
Sep 18, 2007
The 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.
I'm on an early 2008 mac pro - used to be on a Powerbook G4. I have a 300 GB LaCie d2 Extreme external HD connected via firewire 800. Both are in 10.5.2. While on my powerbook, the drive behaved normally - fell asleep after no use, then awakened when I needed to access something. On my new mac pro, the drive behaves strangely. I only use it for backup, so it's only accessed once a day. The rest of the time I do not use it. When it's not in use, the drive sporadically wakes and sleeps. I've tried to pinpoint the cause to no avail.
I've tried all the usual suspects: browsing the forums, checking the "hard disk sleep" preference in energy saver, switching the firewire 800 cable with usb and firewire 400, watching activity monitor to see if there's a program accessing the drive (haven't found anything, but that doesn't mean it's not there). None of it works.
Every hour or so, my computer freezes up and then restarts itself. Once restarted, it does an error report and tells me that "Sleep Wake" has experienced a problem. Is this a hardware problem? What I should do about it?
As I've read in many threads there's no way to turn off the blue light, even when my imac is off or sleep, and even thou the hdd is (or might) be asleep, the light always stays on... over all this is not a huge deal, but since the imac is in my room sometimes the light it's a little annoying. I was wondering if anyone here has an external hard drive that goes to sleep and even the lights turn off completely..
Specially if it's a famous brand.. like WD or anything along those lines.. since I'm looking to upgrade my external HDD i figured it's a good to know.. otherwise i'm going to just upgrade to the 1tb Lacie.. I'm considering the 1tb "My Book" because even thou I read that the 500gb had a lot of issues apparently the 1tb one is a lot better.. has anyone has had this drive? Any issues?
I'm running out of space on my Mac Mini's disk because of all my iTunes video files. I am thinking about buying an enclosure for my spare 1 TB hard drive, and using it as the location of my iTunes library, but I wondered how it works with the Mac Mini's energy-savings mode. My Mini is set to sleep after 15 minutes of inactivity, then wake when iTunes content is requested by my Apple TV or Airport Express. I like it, because it's very energy efficient that way! My question is, will the disks also sleep along with my computer, and will they wake properly when the computer wakes?
I 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 cannot see my external hard drive. I cannot see it in finder. When I started disk utility it says I need to repair but than it says it cannot be repaired. Is there a way I can reach the data? I don't know what happened to the disk.
This started recently and is quite annoying. Like the title says, if I put my computer to sleep via apple menu/sleep while it is attached to my external monitor the computer will not "wake up". When I try to wake up the computer the sleep indicator stops pulsing and I can hear the hard drive start spinning. As a result I must force shut down the computer by holding the power button. The computer is fully charged so it is not a low battery issue. The external monitor is an 20" Apple Cinema Display, it is attached via Apple's DVI connector.
Unplugging the monitor dongle and replugging it in do not work. Pressing any assortment of keys does not bring the display back up.
I've tried resetting PRAM, disk permissions, and verifying the disk.
I have an external 2TB Western Digital Caviar drive hooked up to my 2006 iMac through a docking bay and USB 2.0. I'm running 10.6.6 and the drive is formatted as Mac OS Extended. It's my media and backup drive and I'm always copying stuff to and from it. All was well and good with the setup and I had no problems for probably 5 or 6 months. Just around Christmas, though, I started getting alerts when trying to copy files over to the drive. Error Code: -50.
Basically, I can still view/read files on the drive and play songs in iTunes, but if I try to rip a CD, iTunes hangs and dies. If I try to copy any file over using the Finder or empty the trash with files from that drive, I get the -50 code and alert. A restart will fix the problem for a little while but then it's back after maybe 30 minutes or so that's obviously not a good long-term solution. This page claims it is an "Error in user parameter list" but I have no idea what that means. I've done a bunch of Googling, but people are saying it's anything from problems with networked NTFS drives (which it's not for me) or that it's a disk permissions issue (no bootable system on the drive).
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?
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 received an Acomdata 2Tb external hard drive today from Amazon and plugged it in. Time Machine popped up and I declined to link the hard drive to it. I went into Disk Utility and chose the new hard drive on the left column and went to erase. I chose Mac OS Extended. I named it and hit erase. It started going, and going..... and going... and a half an hour later I knew something was wrong.
Disk Utility was not responding and I eventually had to Force Quit. Now I cannot format the hard drive. I starts and then it stops with a disk error. I tried to run the First Aid verify and repair and both stopped after a few seconds with an error. What do I do?
I have latest iTunes 10.6.1 and its library located on external drive, connected by FW800.
System properties -> Energy saver -> Put the hard disk(s) to sleep when possible is On Everything works perfect in case of local access.
Also in case library's drive sleeps, it takes just several seconds more in order to wake drive. But remote access works only in case the drive is waked somehow. I.e. if Home Sharing is enabled and drive sleeps I cannot get access to the content from remote iTunes or Apple TV.
I think it is a bug, remote access shall be not broken in case the drive is sleeping. Also it is known, some forums explain that you shall never put external drives in sleep mode in case this drive used for iTunes Home Sharing [URL]
I was trying to set up my Time Machine to an external hard drive. I didn't continue because it asked to "initialize" the hard drive which I had a lot of important things on.
I have another external hard drive I'd like to use but, my Time Machine has this error code of -43. What is this and how can I use my Time Machine on another external hard drive?
with cloning/copying the content one an external hard drive onto a new external hard drive. Basically, I have a 500GB FW400 drive which I use to store my media files. It's full, so I purchased a 1TB FW800 drive to replace it. Obviously, I thought I could simply copy and paste the media files from the old drive to the new one.I cannot copy the media files to my internal drive first as my internal drive is only 250GB and nearly full itself.I have used Disk Utility to attempt to close the old drive to the new drive, but keep getting "insufficient space" errors.
Recently I bought 2 identical WD Scorpio Blue 1TB hard drives for my macbook pro 13 inch 2010. My aim is to replace the internal hard drive with one of the two I just purchased and use it as my system drive with Lion, Windows and Data partitions. And for the other hard drive I want to use it as a full disk back up for the internal drive (now 1TB hard drive).After I was done with setting up both windows and mac and data transfer, when I booedt into the recovery partition from the internal drive to clone the drive to the external drive, the disk utility gave me this error (Could not validate source - error 254). I also tried using Carbon Copy Cloner but it only could clone partitions, not the entire drive. Yesterday I downloaded a copy of Clonezilla. It worked fine until it had to clone an exFAT partition (my data partition). The exFAT partition appeared as 'RAW' partition in clonezilla. As a result, the whole partition appeared to be full and clonezilla had to copy every single blocks of data in that partition and the estimated time remaining was about 30 hours. So clonezilla is out too. Just want to ask if there is any program/application (bootable or not) which allows can do a full disk clone to an external hard drive.
Is it possible to have an external HDD connected to an iMac or Mac Mini on a regular basis? I have a Power Mac G4, and it's always had issues with going into sleep mode when there is any external storage connected via the USB 2.0 ports (and I've put in replacement ports to try and remedy this, to no avail). The main problem is that once the system wakes up, it thinks you've improperly removed the device. Apple told me, way back, that this was normal and to just eject all external storage before going into sleep mode. Which is a pain, but looking at a new desktop Mac I would like to just get the tiny, base HDD and use a beefy external for all my media - unless this is still an acceptable norm with new macs.
Is it possible to manually put an external hard disk to sleep? Right now, I've already got "Put the hard disks to sleep when possible" checkmarked in the Energy Saver preference pane, and so they should sleep after 10 minutes of inactivity, but I'm wondering if it's also possible to do this manually whenever I want.
I just bought an external hard drive and it's already spinning constantly, compared to my current external which is completely quiet, so I'm wondering if I can put it to sleep when I need to to stop it from spinning all the time.
Info: iMac, Mac OS X (10.7.4), 3.2 GHz Intel Core i3, 16 GB RAM
I've had a lot of problems with my iMac G5 power supply and since I have newer computers I've decided to get rid of this computer.
I want to save the hard drive and put it in a case, then use it as an external drive on my other Macs.
What sort of case do I need to shop for? Should I look for SATA or what exactly is the proper nomenclature.
Is USB 2 the preferred choice, or Firewire, or what? Is there a USB 3? I use a mid-2010 27 inch iMac with the intel processor, and I needed to buy an adapter to use my older Firewire external drive. Is Firewire a dodo?
i have a power mac g-5 quad with an external dvd drive and a external hard drive and 2gb of ram. on my ext. hard drive i downloaded mac the ripper and that is where i put all my dvds, now today on my pmac i was using mac the ripper, popcorn, itunes, safari all at once and it froze up on me?why? could the ram be an issue? how may programs can i use at once with my pmac?
For the last few days, since carrying out a software update (dont know what update!) when I select "sleep" from the main apple menu my screen goes to sleep but my hard drive keeps running, how do I correct this so the whole thing goes to sleep?
a couple of days before my wireless track pad and keyboard would have trouble connecting when computer is waken after sleep mode. Then one day my mac mini just suddenly stopped going in a physical sleep state. When I go to the apple sign and put the mac mini to sleep the screen turns black like usual but once its put to "sleep" the light indicator on the mac mini will not blink neither will I hear the hardrive slow down. whats going on. This is the standard $700 model mac mini mid 2011.
I have a new 17" MBP and recently it stopped going to sleep on its own. I can force it to sleep my apple menu or shutting the lid. I have tried everything I can think of... all programs closed, nothing running (to my knowledge) and in activity monitor it shows the disk activity writting every 20 seconds or so... my only conclusion is that it's not letting the HD become inactive long enough to send to sleep... can someone please help me with this?
