Hardware :: Drive Disconnect Randomly - Can't Mount Unless Reboot Imac
Jan 29, 2009
I purchased a Q-Drive Q 1TB in Dec for my 24" iMac, purchased it at a Apple Store. I was connected with 800firewire cable, all seemed to be working ok, time machine etc. But in the past month the drive has become a nightmare, it will just disconnect at random. At that point i cannot get it to mount, unless I reboot my iMac. I have tried to connect with 400firewire and usb2, but the same problem persists. Needless to say I am somewhat annoyed, it was not cheap. Anyone have any advice on what I should do, I'm scared to go to G-Tech for support as what I could find appears to be a nightmare. Would I be able to return this to the Apple store that I bought it from?

im running OSX Leopard on my Macbook Pro and I have a mobile hard-drive attached. My bittorrent client, Azureus, is likely accessing one of the three partitions on the external drive when, for some reason, my system hangs. After a while i I just hold down the power button to force a restart.
After it starts up everything works fine, except that the partition that was in use wont mount, although the other two will without problem.
All the partitions show up in disk utility. If i try to mount the troublesome partition from within disk utility, I get a dialogue box saying the mount failed and I should try first aid. When I try to repair it with "Verify disk", it tells me that the volume "appears to be ok".

My Mac Pro ("Cyrus") has two 1 TB hard disks. When I reboot, only the first of those disks (also named "Cyrus"), the one with the system and home directories, mounts on the desktop. The second disk ("Virtual", need a better name, any ideas?) does not appear in /Volumes and doesn't work until I mount it manually in Disk Utility. This behaviour is seen consistently, i.e. after every reboot. How can I convince Cyrus to mount both disks?

Except for the drive with the system on it the drives (whether CDs, DVDs, Sata Drives, internal drives, Firewire, network,...) drives only mount randomly. And often after ejecting them they often don't disappear and stay on the desktop. I've got a couple of Raids (one internal and one external Sata II) and one of them is hardly ever recognized on startup and I have to get it in the disk utility. Most recently even toast has started to fail if asked to copy cds or dvds (I presume because they are not mounted proplery).

I have installed my hard drive from a previous but terminally I'll iMac that was running Snow Leopard into a Sata to USB enclosure. This is displaying on the desktop of my new iMac running Lion as an external Hard drive,also system preferences sees it as a start up source.My question is , is it safe to restart into Snow leopard without causing a kernel panic and if it does boot will it be fast enough to use as it as a USB drive.

I have had my new iMac 21.5" for about 2 weeks now. Yesterday I picked up a 500 GB LaCie USB Drive to be used for my Time Machine drive. I have the drive connected directly to a usb port on the iMac. Sometimes when the iMac goes to sleep, when I wake up the iMac I get the dreaded "This Drive Has Not Been Disconnected Properly" warning.
I have made sure that the "Put Hard Disk(s) to Sleep Whenever Possible" option is not selected under the Energy Preferences. I have tried multiple usb ports, same issue. This isn't a constant issue, it just happens sometimes. Is there anyway to tell Time Machine to mount and unmount my drive when needed?

Have had my imac for about a year and just recently my hard drive changed from "c:" to "+++++". I changed it to read "hard drive" and then a few days later it changed again to "5+". Why is it doing this?

There is something that has been bothering me something fierce since I made the switch to the Mac.
When I used Windows I could connect and disconnect USB drives whenever I wanted without fear of losing data. The way Windows works, it's designed for this so you don't have to "eject" the disk every time.
OS X however is different. I have a USB hub, which has at any given time at least 4 drives plugged into it. If I want to say, grab my laptop and head out the door, I have to wake it up, eject all the disks/media cards, and then go.
I find this to be extremely annoying, especially when I forget.
Is there a way to make OS X behave like Windows in this regard?

I've been longing for a bit longer battery life, and I was just wondering if removing/disconnecting the optical drive would make a difference. I don't need it, and common sense says I could just disconnect it.

I noticed that Time Machine backs up the system ever so often. What happens if I disconnect the external hard drive I'm using as the back up and Time Machine tries to initiate a back up? Will it corrupt anything?

I forgot my admin password on my iMac recently and so i used the reboot with OS X snow leopard install disc to reset the keychain, but now on my login screen, it used to be just my account name, there is one called "Other" so i went into accounts in system preferences and tried to delete it but it isnt there?is really annoying me p.s. the "other account" isnt actually an account it says "Other" and when you click on it asks for your username and password...so i type in the admin accounts name and password (admin account is the only one on this computer), and it just opens up my admin account.

I have a MacBook with Mac OS X and Windows Vista Pro installed. Having both of these OS installed as well as Xcode, this occupies a LOT of memory and there is very little else available. So, I have a 100 GB USB external drive. I am fairly new to the Mac and so need a little help. The USB port must be extremely sensitive. If anything barely touches the USB cord to the external drive, then Mac OS X cannot "see" the drive anymore and there is an error about properly ejecting a drive. The only way that I can get it to see the drive again is to boot into Windows Vista, restart and open Mac OS X again.

I recently performed an optical drive install. Had to remove the hard drive bays (I use three hard drives - Luckily, 2 run OSX). I carefully removed all three drive bays and the empty bay. When I inserted the drives into the computer I had changed the position, swapping one OSX drive with a different one and reversing the drive bays. On restart, the computer started on the drive I had not selected for startup and I received an error message stating the other drive could not mount and it gave three options (Initialize - Ignore and Eject).
I can see the drive in Disk Utility and repair the permissions (it's also located in the System Profile).
I tried a few things I read in the community using various Terminal commands but was unsuccessful.
(Let me point out that I recently switched from a PPC G5 to MacPro and swapped the drives from PPC into MacPro and all has been fine until I removed changed their positions in the bays)

I recently ordered a 27" iMac from Amazon and I am expecting it to arrive in the next day or two. I am considering using a desk mount arm as a mounting option. What brand desk mount arms are others using for their 27" iMacs?

I am trying to install Ubuntu on Mac and for that I've created a bootable USB drive with Ubuntu on it. Now when I'm restarting my Mac and pressing Option key on keyboard, it is not giving me any option to boot from USB. I don't think its getting detcted even. USB is currently formatted in FAT format. Just wondering if there is any other format required?

My imac is 10.4 tiger which over the years is now updated to version 10.5.8. It regularly crashes and is getting worse - at least twice a day then i have to turn it off with the power button. When i go to reboot a folder with a question mark appears on the screen. I usually then have to turn it back off and wait several hours for the mac to reboot again...

I have resolved my MacPro sleep issue by removing the Seagate 320GB stock drive. For whatever reason, if that drive is plugged in, it reboots my MacPro when waking from sleep. I had setup 2 WD 500GB drives in RAID 0 as my boot volume and this was configured with Windows XP Pro for other uses.

For about a week now, every time I boot my iMac mid-2007 20" running 10.6.3 I get the following problems
-Booting takes about 15 minutes of seeing the apple logo, and a bar that fills slowly under it...
-When it finally boots all the dock icons are reset to the ones you get with a brand new mac, spaces and expose is reset as well.
-Spotlight reindexes Macintosh HD.
-Adium loses all contact icons
-Mouse loses all it's custom settings.
-Login items are gone, I have tried not to re-enable those.
-Shut down takes about 10 minutes as well, while I see only the blue screen of shut down...
It seems that it is losing more and more settings every day. Today I had to turn on time machine again, although it was on before shut down...
Is this like losing an application support folder or something like that?
Applications do not seem intact as well.
Safari loses all web screenshots from cover flow iTunes reupdates the library etc....
What's up witn all these?

I received an iMac G5 from this old couple, they were going to throw it out, but all it needed was a power supply which I bought and replaced. It's been about 9 months and everything worked great, no problems whatsoever.
Three days ago, I shutdown the computer and when I booted the next day, it would only reach the Apple logo and the spining wheel, the fans would blast loud and then it would shut down and restart again, repeating the same thing over and over. I cannot start it under Safe Mode nor it recognizes the CD when booting.

I tried searching for a solution for this and can't find any. I've seen one other threat in here about similar problems but the variables in my case are different. Here's the thing, a friend of mine lent me her usb pen-drive. She uses it on a pc mostly at work. When she gave it to me she forgot to copy some files i needed so she plugged it into her macbook pro (one of the new ones from this year, intel, snow leopard and stuff), copied the files i needed on it and i took it home. I have an intel imac, bought on april 2009. I plugged the usb pen-drive on my keyboard usb port and nothing happened. So i took it out, plugged it in again and nada. I did it a 3rd time and this time it showed me a message saying that this pen-drive needed more power and i had to try plugging it into a different usb port. So i plugged it in the back of my imac and nothing happened, not even the "insufficient power" message. It doesn't mount, won't show up in the desktop nor in the sidebar of a finder window.
I checked the disk utility and the pen-drive shows up there. I see the "main" pen-drive and it's "partition" (i dunno how to call it... mmm... you know, like you're seeing the "parent" drive and its "son" drive but they're "one and the same") and i can see its tech info and i noticed it's formatted NTFS. Since it worked just fine on my friend's macbook pro, i can't figure out why isn't it working in my imac. I know macs can't write NTFS, only read (mine doesn't at least) but hers wrote info in the pen-drive no prob. Another thing i noticed is that the "son" drive is grayed out. I can see its tech info but it's grayed out. Verifying the drive simply shows a message saying "Verify volume failed: Invalid request.".
So, i have no clue as to what's going on. I could give it back and ask my friend to format it as journal or whatever it's called to be mac os compatible and copy the info back again, but i don't know if that'd be a solution until i'm able to try it in a few days. Can't ask her to format it fat32 since the file i need is larger than 4gb, so yeah. Any clues as to what could be the problem? I even tried unplugging any usb peripherals and no dice.

I understand macs can mount .iso with a simple double click, but I want my macbook to treat an iso file as if it were a CD in the cd drive. This is easily done on a C with PowerISO or Alcohol120% I should be able to do it on a mac too, shouldn't I? But I can't seem to figure out how to. When I double click the iso to just mount it, it mounts fine, i can access files and everything, but if I run a program that reads of the CD i of course get the "Please insert CD". Now, I have the CD right here, that's no big problem, but the using drive kills the battery life like nothing else.

Macbook 2.4Ghz with Leopard 10.5.8, 320Gb drive (2 partitions)
Doing the standard upgrade install so I shove the SL disc in and run the installer, after an age it eventually reboots.
Then after another long wait the installer finally appears but when it asks to choose the drive to install to, my drive doesn't appear.
From the utilities menu, I can access disk utility and it only shows the DVD drive.
If I access system profiler my hard disk is still there in the SATA section.
Seems like I'm going to have format and do a clean install unless anyone has any ideas?

I have an annoying problem when I start up my external hdd in OS X. Let's say the location for the disk is: /Volumes/disk A. Sometimes (often) after a reboot or just a restart of the external hdd in OSX the location becomes: /Volumes/disk A 1. The system adds a 1 to the location of the disk!?!? Torrents cannot found the location of existing downloads and it's the same with my usenet client. The only way I've managed to solve the problem is to try to restart osx + external hdd until the location becomes /Volumes/disk A again (or recheck ALL torrents to the new location). I haven't found any logic when it goes back to the original place yet so often it takes a while to get it right.

I have a drive connected via USB 2.0 It's newly formatted with 2 partitions. Running 10.5.6 on a macbook.
The drive seems to work fine, the problem is whenever I reboot the two drives don't mount in finder.
When I look in disk utility. I can see the drive listed but the partitions are not.
I have to manually unplug and re insert the drive for it to function correctly.
