USB issues with External Drive

I am running a 1 TB Fantom drive (MDC1000) (2 Partitions) on new OS 10.5.6 MacPro via one of the back USB ports. Been using the drive for over a year with no problems.
Now intermittent issue with mounting drive. After successfully mounting and letting the drive cycle down, the USB2 connection disconnects when the drive starts back up again. I receive the Device Removal Message, then the drive tries to remount. Then I receive the message again. What is strange is that the drive seems to work fine when data is being accessed consistently.
I clicked off the "put the hard disc to sleep" checkbox in the Energy Saver preference which seemed to stabilize the intermittent problem, but now there is an issue with the machine not coming out of sleep, and I get the startup clock icon when I try to restart. The machine does not shut down with the USB connected.
I'm still trying to determine if it's the drive or the machine. I ran the disc utility and repaired the disc as the intermittent disconnections seem to corrupt the trees and directories. I am able to fix them. Is there any utility for testing the USB ports? There should BE.
Could this be due to a recent update? Or lack of firmware update from the drive manufacturer? Seemed to come out of nowhere.
Thanks for any info.

Just to follow up with this for anyone has a similar problem.
Tried new cables and seemed better for a short time, but then still would not mount successfully.
I called Micronet after I didn't hear back via their email form. The tech there seemed to suspect it was the power connection on the network card in the drive which would make some sense. He confirmed there were no firmware upgrades for the Fantom drive.
Also tried to mount the drive unsuccessfully via Firewire and it did not work.
So my conclusion is that it's not the drive mechanism but the network card in the drive. I have a sinking suspicion that there is a power issue in my office space, which may have affected the drive. I've had other machines and devices which have had power issues in the past.
Does anyone know any simple and easy way to test electrical integrity in a work/office environment?
I bought another 2tb drive, transferred the data and reformatted the old drive to see if that does anything.

FireWire issues with external drive in Yosemite

I have just upgraded to OS X Yosemite, and I have an annoying problem with my 500GB FireWire external drive (which I use for Time Machine backups).
Basically, after updating the drive won't show up anymore, neither in the Finder nor in the Disk Utility. I also tried the "diskutil list" command in the Terminal, but it is nowhere to be found. Note that the drive does indeed receive power from the port - it spins - and when I look into System Report --> Hardware --> FireWire it does show up there (but I can't mount it). Furthermore, if I use a USB cable to connect the drive everything works fine, so the disk itself seems to be OK.
The funny thing is that if I boot with the drive plugged in the FireWire port the system mounts it normally. But as soon as I eject the drive, I am unable to mount it again (unless I switch to the USB cable, as mentioned above).
Prior to the update, everything worked flawlessly. For now, I backed up my Mac via USB 2.0, but it's very slow and I definitely don't want to resort to this workaround everytime. And it goes without saying that I don't like having issues with my primary backup device in general.
I already did all the usual troubleshooting (rebooting, resetting NVRAM and SMC, ...), but the problem still persists.
Any suggestion?

I had the same issue on a rMBP 13'', brand new 2015 March.
Two thunderbolt adapter connected: one for ethernet, one for firewire Lacie drive.
and...
even after taking the ext. Firewire on the Spotlight exclude list, and also after disabling sleeping hard drives, I always got the issue.
Until I realized that touching the laptop or moving the screen was immediately leading to disconnection.
Then I exchanged the thunderbolt connectors, and now it is stable and does not disconnect again.
??? Maybe one of the ports is more "delicate" than the other?
Big hardware weakness here...

Issues with external drive on Mac Mini / Lion

I'm using an external SATA drive in a Newer Technologies Voyager dock (which I like to call the "toaster") with a brand new Mac Mini i5 2.3G via FW800.
The drive was formatted using Disk Utility on a G4 running Tiger (10.4.11)
With the drive mounted, the Mini's performance seems to slow down, and it randomly dismounts the drive, with the usual warning, "you disconnected your drive without dismounting it first, bla bla...)
I think I remember when Leopard was new, there was a firmware issue that had to be dealt with, and when moving drives from OS 9 to X and back to 9, I lost access to the data on the drive.
I'm also aware of the partitioning scheme difference when formatting drives for use on the Intel machines.
Could either of the above have anything to do with the problem I'm having here?

I'm not an expert in this, but as far as I know, GUID only comes into play if you want to boot from it, but...... you never know, it could - here is an excerpt from Disk Utility:
If you’ll be using the disk only with Mac computers, choose GUID Partition Table.
Another thought is: how old is that drive? All hard drives fail sooner or later - have you tried to check it with Disk Utility or something like Disk Warrior?

USB Issue with Flash Drives

I am running XP Pro with SP3 and all updates as well as all Bios updates with Lenovo.
I have an issue with my USB ports. Everytime I put a USB flash card in any slot I do get installation and driver installed correctly. But when I go to the Explorer I get "is not accessible" Then it says under that "The process cannot access the file because it is being used by another process" But when I leave the USB flash drive in the drive and reboot I am able to to access the drive. Any suggestions on this issue I am not sure if it was the Bios update or one of the XP udpates. Anyone else come accross this issue?
Thanks,
Scott

Would you try this:
Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
I don't know what you are looking at to determine space available. You need to do that by selecting the device's Desktop icon then press COMMAND-I to open the Get Info window. The capacity and available space will be displayed in the Get Info window. A portion of the device will be allocated for the RDB and directory, so some space will be shown as in use.

ITunes library issues with external drive - HELP!

Hey guys,
I just got the Time Capsule and am using it to store my iTunes library. I went to preferences>Advanced and changed the location of the iTunes Library to my time capsule HD.
The problem I am having is that every time I disconnect from the network iTunes defaults back to user/me/music/itunes and I have to redirect it and then click yes for "organize my library" and then it updates the library, blah blah...
This is very annoying, does anyone have any suggestions?

Try this post;
http://support.apple.com/kb/HT1449
Maybe the most useful hint for you is the last paragraph "If you move your library to an external drive, you'll need to power up and connect the drive before starting iTunes. If you don't, iTunes will prompt you to either locate the library or to create a new library (which will result in an empty library)."

FSCK and reboot issues with external USB drive

I'm having an issue with an external USB hard drive I'm using. I've always had issues with this drive cause my reboot to "freeze" when it's mounted. Basically the system message with be sent out, but it doesn't actually proceed with the reboot. No switch to init 6 or anything, but the shutdown process is still active. I can continue to use the computer as usual, but I can't cancel the existing shutdown or try to enter init level 6 by hand. So I just got around this by unmounting the drive before I shutdown. However, lately when I try to unmount the drive I get an error saying that the drive is in use and I should check to see what processes are using it by runing lsof or fuser.
Yesterday I tried copying dsome files from the drive but there wasn't and activity on the drive. cp didn't report any errors though, it just sat there and did nothing. I tried running fsck on the drive, but didn't get much farther. I'll see some activity on the drive for about a second, then all activity stops and fsck just sits there. When I try to kill fsck, it won't. Even with a kill -9.
I'm really confused as to what is going on. Has anyone else had this problem? Anyone have any ideas what could be causing all this or what I can do to stop this? Thanks in advance!

Press the reset button on the device. It is located between the USB and power ports. Make sure to take-out the external USB drive before you reset the device. Or you can also restore the defaults by accessing the Administration tab > Factory Defaults sub-tab in the router’s web-based setup page. Check out this link for the set up; http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=32cffead811249aea7e9fc6730bf59ad_KB25681_EN_v1.xml...

Issues with External Hard Drives

I hope this is the right forum for this one - please give me a steer if not! I've also posted it in 'Dock and Finder', but this forum seems equally appropriate, if not more so.
I'm getting repeated issues with External Hard Drives, including ones that I have been using successfully for months/years, suddenly failing to mount and then becoming 'unknown device' through the firewire branch of 'About This Mac'.
I've just bought a new hard drive on the grounds that the others had somehow failed, and the same problems are emerging. I decided to Repair Permissions on my iMac's internal drive, and am copying the results below, from repair runs conducted yesterday and today:

My concerns are:
* Some of the permissions repaired yesterday appear to have needed to be repaired again today
* There are several files which carry a warning that they won't be repaired as they have been 'modified', and some of these clearly relate to disk management.
Does anyone have any ideas what is going on???
Thanks!!

Many problems with the 10.5.7 update have been fixed by a Restart.
If that doesn't help, something may have gone wrong with the update. Download and install the "combo" update, from: http://support.apple.com/downloads/MacOS_X_10_5_7_ComboUpdate
If that doesn't help, try running the Apple Hardware Test, on the disc that came with your computer.
1. Disconnect all external devices (including the Ethernet cable) except the keyboard and mouse.
2. Insert the "Additional Software & Apple Hardware Test" disc that came with your computer.
3. Restart while holding down the "C" key. When the list of available startup volumes appears, click Apple Hardware Test and the right arrow.
4. When the Apple Hardware Test main screen comes up (after a moment), follow the on screen instructions.
5. If it detects a problem, an error code will be displayed. Make a note of it.

OSX can no longer find USB 3.0 external drive

My macbook air was able to read from my USB 3.0 external drive a couple weeks back when I last plugged it in prior to yesterday. Yesterday, when I plugged the drive back into the computer though, my machine was unable to detect the drive at all. It was not in finder, the desktop, or disk utility. Nor was it visible with the "diskutil list" command. I plugged the drive into a separate windows PC, which was able to access it fine. I scoured online for some tips, and ended up trying to use the usb prober tool, which didn't work. The drive has its own power adapter, and is not bus-powered. It turns on whenever I plug it in, but my machine is not able to detect it. I do not have another USB 3.0 device to test the macbook air with, but I have used other USB 2.0 external drives, which are detected by my macbook air fine. I updated to 10.8.3 before I plugged the USB 3.0 drive in, but I am not sure if that would be the cause of this issue. Are there any other tips that I could try that may remedy this issue? Any advise would be much appreciated with this predicament.

Try restarting your Macbook then plug the USB External Drive again and see if that works.
if all else fails - try doing a SMC RESET and see if that sorts it out for you.
Good luck

Mavericks 10.9-10.9.1 bug/issue/problem: external drives connected through thunderbolt or firewire are not put to sleep when iMac goes to sleep

Previous to Mavericks (10.9 - 10.9.1) I've had no issues with external firewire or thunderbolt connected drives to be put to sleep. However, since Mavericks all of my external drives are not put to sleep when my iMac, or Mac Pro go to sleep.
How can a company such as Apple, pushing people to have external devices like hard drives, is not on top of fixing this issue? Apple pushed for firewire and thunderbolt, thus All external drives I've owned are firewire. Because of speed. I bought thunderbolt adapters for firewire, and before Mavericks all worked great. Now that we have 10.9.1 update, this is still an issue!
I'm aware of the temporary solution of connecting the drive through USB to make it work, this is not a solution, but a hack.
Please let Apple know that this is a known issue, and there should be a fix for it. Everyone's data depends on it! Not only current external backups, but also external sensitive hard drives we rely on. Currently, the following makes are experiencing this issue: Lacie, OWC (Elite Pro), WD, Promise, Seagate, Toshiba, G-Drive.

Same 2 issues with 10.9.3:
External FireWire drive WILL NOT spin down when Mac goes to sleep.
also
External FireWire drive WILL NOT spin down for inactivity despite “Put hard disks to sleep when possible” is checked in energy saver.
This has been going on since the launch of Mavericks and no solution found yet.
USB ports work normally.

Why does my Thermaltake Silver River 5G USB 3.0 External Drive keep disappearing?

Hi All,
Having major problems with a Thermaltake Silver River 5G USB 3.0 External Drive (http://www.newegg.com/Product/Product.aspx?Item=N82E16817153160). External drive contains Western Digital 2TB drive (http://www.newegg.com/Product/Product.aspx?Item=N82E16822136891). I'm running Mac OS X 10.8.3 on a 2012 Mac Mini.
Basically, I can plug-in or turn the drive on, it mounts fine. Can run a Time Machine Backup. At some point (and I think it's when the computer goes to sleep), the drive hangs and I can no longer access it. Time Machine will hang on "Looking for backup disk". Drive will still appear in Finder, but I cannot "Eject" it. I've also tried to do a "umount -f" on it from the Terminal. Disk Utility still "sees" the device and the disk (partition?), but can't run a repair.
The only way I've found to fix this problem is to reboot the machine. I've crawled through the System log, but I don't see anything that points to a problem.
What else can I check? I'm have no idea if it's the hard drive, the external USB enclousure, Mac OS X, or the Mac Mini that's the problem. Please let me know if there is more information I could provide to help solve this problem. It's really frustrating!!!
Thanks!

I received an answer from Thermaltake technical support. I asked if perhaps there was a firmware upgrade to prevent their drive from disappearing. They wrote on 22/04/2013:
Thank you for contacting Thermaltake Customer Service.
No firmware to do it. Just set system to never sleep. System will cut/disconnect the USB when it into sleep mode.
I wrote back saying I have never had to do that with other USB devices. And I routinely allow my system to Sleep. Is that an issue with their drive housings? They replied on 23/04/2013:
that is issue with sleep mode.
I don't know if this occurs with other USB 3.0 drives and Time Machine. Somehow, I doubt it. Anyway, it sounds as though my Thermaltake is destined for eBay...

USB 3.0 external drive extremely slow on Macbook Air 2014

Dear Apple Support Team & Folks in Apple Community,
Seriously, I have a problem with my new Macbook Air 2014 which has equipped with USB 3.0 port. I read through the forum and hardly find a solution for this.
Recently, I plugged in my USB 3.0 external drive and expect that it would reach the same file transfer speed as that on my PC. Instead of 625 MB/s (5 Gbit/s), it was hardly reaching 60 MB/s (480 Mbit/s) to my surprise! Sounds like Macbook Air doesn't recognize USB 3.0 device properly. I have tried Western Digital and Seagate devices but failed to get reasonable transfer speed on my Macbook Air.
I tried it again with my USB 2.0 external drive on Macbook Air and only got the transfer speed around 15 - 20 MB/s which is disappointing.
Any patches or Firmware updates would be appreciate!
I have OS X 10.9.3 already with EFI and SMC update patched by App Store.

I would be interested to know which consumer grade non-raid external harddisk that could reach 6xx mb/sec.
The speed you mentioned should be normal, since most of these are 5400rpm drives (asumming it is 2.5 inch).

Finder crashes with External Drive on Sleep Mode

I purchased my new iMac 21,5" less than a week ago, and I haven't had a problem with it except for one that it's been bugging me a lot.
I have a LaCie 1TB Quadra d2 external drive that I use to store footage (since it's HD, the filesize won't fit in my 500TB internal hard drive), but I noticed that sometimes when LaCie external drive enters in Sleep Mode, the Finder freezes and the only two ways around this, is to force reboot, because the Finder won't answer and won't open again, or unplugging the external drive without ejecting him first, which it's not safe for me to do, because I'm afraid of hurting the device, and the files in it are pretty important.
This happens almost everytime, especially after a long time on sleep mode. I usually leave Final Cut Pro transferring files all night (since it takes a long time) so I kinda need the sleep mode, but when I wake up, Finder and Final Cut Pro won't answer.
I updated to Snow Leopard 10.6.8 on day one. Is there a way to fix this? Is it normal? I read somewhere that some users were having trouble with external drives on Sleep Mode, but I can't seem to find any further information about this problem.
Thanks!

I've got a MacBook Pro 13.3" that's a little over a month old, with a LaCie 1TB LaCie d2 Quadra with USB 3.0, #301542U and I'm suffering the same problems and a few others with it. I've got a partition on it set up as my Time Machine backup drive. I've turned off the Put the hard disk(s) to sleep when possible in the Energy Saver preferences but I'm still having the sleep problem with it. According to the LaCie Manual:
By default, your drive will enter Eco Mode after 30 minutes of inactivity in order to conserve energy. To exit Eco Mode, simply access data on the drive and the disk will automatically restart. You can manage this feature using LaCie Desktop Manager. Click the Eco tab.
The LaCie Desktop Manager (in my case) only takes me to the Energy Saver Preferences in OS X to adjust the time there. Turning off Put the hard disk(s) to sleep when possible doesn't seem to make any difference, the drive still goes to sleep after 30 minutes. However, after 15 minutes the drive seems to wake back up, but then during the next 15 minutes goes comatose (no power light). Sometimes it will go through multiples of these sleep wake cycles without going into a coma, but eventually it does go into a coma. This happens in between hourly Time Machine backups.
After locking up Finder, Disk Utility and Time Machine multiple times trying to access the drive in this state I figured out that I could cycle the power switch to regain use of it (with a Finder warning of course) but this will only lead to file corruption eventually and I shouldn't have to resort to this. I've also dismounted it, expecting it to turn off and instead it goes into an extended spin down cycle (rapidly flashing light) and never turns off (or goes to sleep or what ever it's supposed to do) and once again requires turning the power switch off.
This is just too unpredictible and unrelable for me and as soon as I get the opportunity to do a 7 pass erase I'll be returning to the place of purchase. Based on the reviews of other external hard drives a drive from another company doesn't look to be much better of a prospect so I'm not sure what I'm going to do.

Serious problems after Mavericks installation with External Drive Lacie P9220.

Experiencing serious problems after Mavericks installation with External Drive Lacie P9220 1TB. Mac Finder totally locked!
I had to format the External hard drive with a Windows PC (fat32), then format again with my IMac (mac Journal.) and hopefully restored data from time machine backup.
So far so good but system looks unstable. Some software were not able to write on the hard drive.Some strange things happens. With Mountain Lion never had an even minor issue.
I read many discussion regarding problems with WD, just wondering if anyone had the same problems with Lacie and if there is any tip to solve the
problem.
Many thanks.
Marco

Thanks very much for your reply.
Unfortunately I couldn't find a solution because the article refers to whom have configured the drive with included software and drivers that came with the drive.
This is not my case, I never used any third party soft ...only OS X disk utility ...

IMac won't boot with external drives attached

I am using iMac 27" Late 2013 model upgraded to mavericks 10.9.4. Two external drives are always attached with it, one is segate 3.5" 2TB USB 3.0 drive and another one is 2.5" usb 2.0 drive.
when i start my imac with external drives attached it won't boot up. Stuck at plain white screen after a startup chime, not even any apple logo or any progress circle appears. And i have to detach all of my drives to make it boot.
This problem arises after upgrading to mavericks. Already tried resetting PRAM, SMC and checked Startup disk and verify disk with disk utility.

Raja,
Do a SMC reset perhaps even a couple of times and see if that helps. Also in System Preferences + Startup Disk make sure the internal HD is selected.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

945GT Speedster-A4R - and USB 3.0 external drive

Hello
I just got a USB 3.0 external drive, which I wish to connect to the 945GT Speedster-A4R board. However when the external drive is connected, the board will not boot, but hang in the post screen right when initialising memory.
If I connect the external drive after windows log-on, it works fine.
Anything I can do to be able to boot the board with the external USB 3.0 drive already connected ?
Br.

Thanks for the fast reply !
However I don't see that option in the BIOS.
I see the following options:
USB Controller [Enable/Disable]
USB 2.0 Controller [Enable/Disable]
USB Keyboard Support [Enable/Disable]
USB Mouse Support [Enable/Disable]
