Powered USB hard drives non-responsive awaking from sleep

I have an external powered USB drive connected to the 24" Cinema Display built-in hub on a 13" Macbook (early 2009). When the computer goes to sleep then wakes up, the external drive is unresponsive. This does not happen when the drive is directly connected to the laptop.
I do not have a disconnect error upon wakeup and the computer still sees the drives connected. It just won't spool them up and make them accessible.
Other non-powered items on the Cinema Display's hub wake up fine like card readers and USB Turbo 264 dongles.

This seems a pretty close match for the issue I've seen with my 2009 13" MacBook Pro and 24" Cinema display. I thought the Performance Update 1.0 might have been intended to address this (described as 'addresses intermittent hard drive related pauses') but I've applied the update and am still seeing this issue.
Obviously it can be worked around, but it would be great to be able to use the usb hub on the display for a backup drive.

Lose connection to external USB hard drive after waking up from sleep

My Mac lost connection to the external USB hard drive after waking up from sleep. I can still see the folders in the hard drive in Finders, but when I double clip a folder no file within the folder is displayed. I have to reconnect the hard drive with iMac to read its contents.
May I ask how this happens and is there a solution?
I'm using Paragon NTFS for Mac OS X to read from and write to NTFS format of USB external hard drive.
Thanks!

... I un-ticked the "put hard disks to sleep when possible" option in the Energy Saver panel in the System Preferences, and it seems the problem is solved. will have to sleep and wake up my iMac to further verify if this is the solution ...
Alternative advices are always greatly appreciated!

A305D-S6886 New Hard Drive - Can't Wake From Sleep, BIOS issue

Well I hope this is the right area and this gets listened to, I use sleep often... >.<
Laptop is a A305D-S6886 Satellite bought from ToshibaDirect.
So I dropped my laptop, and the HDD is busted. No biggy right? So I bought a new one. Spefically this one. It is a Western Digital, my Dell laptop friend used it, good reviews, exact equilivant to the one I use. Great!
So I add it right in, easy enough. Boot up the laptop, install Windows 7 x64 Ultimate. Install all of my software, Toshiba software, copy all files, all updates, etc. It is done!
Go to school next day, and while using laptop it feels funny, like it keeps hanging. Why? It hangs when I try to resume from sleep/standby OR hibernation! That won't do. I do a bit of Googling. Tried that hotfix for 1 TB or bigger SATA hard drives, didn't work. More Googling shows this is an issue with Win7 in the beta/release client, both 32 and 64 bits. Nothing on the RTM or build 7600 except for the 1 TB or bigger SATA hard drives. Hm, maybe the HDD is broken?
With into Ubuntu 9.10 x64 Desktop edition, opened up wonderful thing called "Disk Utility." It said the following: Disk was healthy, no bad sectors, and Self-test past. Well then let's run a through SMART test! I did, and it still passed. Hm, hard drive seems perfect, so what can I do? Fiddle with BIOS settings of course! (I have version 2.10)
So the only option I could find related to SATA or HDDs was SATA mode, which had the follow options: Compatibility or AHCI. It was on AHCI, so let's try Compatibility! That didn't work, still crashed. What is next? Let's install OEM Vista that came with my computer! (Vista SP1 x64 bit)
So yay, it is done! Let's put it to sleep! What's this a crash? Then it is OS independent! Now to decide which hardware it could be: BIOS, or hard drive. Next up: stick it in my desktop and install Windows 7!
So yay, w7 has installed! Put it to sleep, it works fine! Wow what could it be? I didn't have an OEM partition before, because of the new driver, could it have been an update, or maybe the BIOS? Clean install and back on laptop!
3rd W7 install later, it crashes on sleep! OEM and software/drivers is out, so that leaves BIOS! D: This took me 2 days, and I don't think I missed any possibilities. I am pretty technically able and confident, so if you have any idea what else it could be, please reply! I use sleep often! D:
P.S. I want more options in the BIOS! D:
EDIT: Maybe some specs may help:
One of the 1st A305-S6886 made I think:
AMD Turion x2 RM-72 at 2.1 GHz
4 GB DDR2 RAM at 800 mHz (Maybe 667 mHz)
ATI HD 3470 and HD 3200, in "CrossFire"
BIOS version is 2.10
Screen size is 15.4
Chicony WebCam is broken, due to cable tearing in the case (I voided my warrenty D
This exact hard drive
Windows 7 x64 Ultimate currently installed
EDIT 2: Also, it SOMETIMES seems to resume from sleep, specifically after long periods of times in sleep mode.
Solved!
Go to Solution.

Sounds like something else besides the hard drive was "busted" when you dropped it. Does it do this when you use hybernation as well as when you use sleep?
If you don't post your COMPLETE model number it's very difficult to assist you. Please try to post in complete sentences with punctuation, capitals, and correct spelling. Toshiba does NOT provide any direct support in these forums. All support is User to User in their spare time.

External Hard Drive Fail After Waking from Sleep

Hi,
I've been having this issue for over a year (since upgrading to Lion, and now still persists after upgrading to Mountain Lion), and I haven't been able to find the exact answer I need after searching through the posts here, and on the internet.
I have a 2011 MBP, and after upgrading to Lion last year, I've noticed that my WD external hard drive for the Mac has issues to be recognized after the laptop wakes from sleep. The drive icons are still there on the desktop, and all the files are listed. However, I cannot open any of the files, and Time Machine backup automatically fails.I am able to eject the drives by dragging the icons into the trash can. However, nothing happens if I simply unplug the fire wire 800 cable and re-plug it into the computer after ejecting the drives. I need to reset the external drive by unplugging both the fire wire cable and the power supply, and replug everything.
Aside from being a hampering process after waking from sleep, this is also very stressful on the drive itself, so I would like to fix this. Does anyone know the issue behind this or have a solution? Thanks in advance!

Thanks for this, and apologies for delay in replying...in between seeing your post I backed up the ext hdd to another mac and used the disc utility to erase and repair and then re mounted the ext hdd. OK. I have then tested the ext hdd being recognised when waking from sleep mode a few times and everything appears to be fine. If this doesn't work (long term) I will follow the instructions as you have suggested....
I now have a new problem with my HP printer (Photosmart Plus) which is not being recognised by a new wireless router..Ok whilst the router is switch on and I have reconfigured the printer..but when the router is switched off overnight and then switched back on...I get a 'printer is not connected' message and have to go through the re configure routine all over. I am minded to think this is a router problem as the same issue is happening to my wifes Mac Book Pro (which is only a few weeks old)...any suggestions..

Since updating to Lion the iMac won't recognise the external hard drive (maxtor) when waking from sleep mode,

Hi All, Since updating to Lion, my imac won't recognise the ext HDD (Maxtor) when waking from sleep mode, I have tried another port, diisc utility (Ext HDD not listed in here) but nothing works. I now find that I have to restart the imac to get the drive recognised..which is fine until the imac goes into sleep mode then I lose the drive and have to restart etc etc.....anyone suffering same issue. The Ext Drive worked perfectly until the upgrade..

USB Hard Drive not showing up in AirPort Utility

I have been using this AirPort Extreme for over two years now and it's been working fine. I finally decided to buy a self-powered USB hard drive so I can share it over the network. However, after I unpacked the hard drive, connected it to my Mac and reformatted it to HFS+ Journaled and GUID. I plugged the hard drive into my AirPort Extreme's USB port and waited. I looked in my AirPort Utility and saw nothing in the disk list.
I spent hours searching online and discovered that I am not alone in this problem, although solutions are rare. I did try one solution where I hooked up the USB hard drive to a powered USB hub and the hub into AirPort Extreme. It actually worked once and after I rebooted everything, even though the hard drive still showed up in the disk list, no computers can connect to it. Although if I connect the hard drive directly to a Mac, it would still work perfectly.
Having a USB hub is not a long term solution not that it's working anymore anyway. I would appreciate any suggestions you may have, thanks!

Thanks for the response. However, I'm not sure what you mean.
So far my experience is far from "Just connect the external hard drive to the USB port on the back of your AirPort Extreme and — voilà".
did you read the support article Daddy linked ? it clearly says

How many bus-powered usb external drives per hub?

I'd like to have two bus-powered USB hard drives (to be used as backups with Time Machine) connected to one powered USB hub. Would that work, or would a powered hub be likely to support only one bus-powered external hard disk? (In that case I could get a self-powered hard drive for my second backup drive.)
Thank you.

Likewise it your needing another External Hard Drive, I would recommend spending a little more for a more rugged Desktop drive to use for storage or backup.
Go with an OWC Mercury Elite Pro or a LaCie Little Big Disk and stay away from those cheap-o WD MyBooks.

Imaging from external DVD player or an external usb hard drive

Hey,
At the High School i work at we are running Netware 6.0 SP5 and Zenworks
4.01 ir6. We have Zen Partitions installed on most computers to store a
local image in case the the computer needs to be re-imaged.
However, we have a dilemma. Every now and then a hard drive will go in a
computer.
When we replace the hard drive with a new one, we install the Zen
Partition, do the config and then our last step is to bring down an image.
Unfortunately our only means of dropping down an image is from the network
either through normal imaging or through multicast sessions.
When we drop an image down from the network which takes up network
bandwidth, it causes slow downs on the users computers and they start
complaining. Our network is running at 100mb.
Is there any way possible to image from an external DVD player or an
external usb hard drive when dropping down an image to a new hard drive in
the computer? Currently I have all my Zen Images on the external USB
Maxtor 160gb hard drive and I also have Zen Images burnt to DVD's.
If so, how do I go about doing this and is there documents on doing this?
Thanks!!!

I have a time machine backup file on a USB hard drive. I bought a time capsule / airport extreme, flat 3TB. I wish to transfer the backup file from the usb hard drive to the time capsule hard drive. 10.6.8

I have a time machine backup file on a USB hard drive. I bought a time capsule / airport extreme, flat 3TB. I wish to transfer the backup file from the usb hard drive to the time capsule hard drive. 10.6.8

Unfortunately, Time Machine backups that are stored on a drive that has been connected directly to a Mac are completely different than Time Machine backups that are stored on a Time Capsule.
Frankly, it is not worth the effort and trouble to try to transfer the old backups to the new Time Capsule.....my opinion....having done this in the past.
It is possible though, but I would not recommend it due to the complexity and downsides involved with this. To give you an idea of how to do this, check out this support article.
http://pondini.org/TM/18.html
Even if you transfer the "old" backups over to the Time Capsule successfully, Time Machine will not simply "add on" to the old backups.
Time Machine will make a new complete backup of your Mac and then add incremental backups from that point.
My advice.....start a new backup on the Time Capsule and move forward. Keep the USB hard drive around for a month, maybe 2 or 3 in case you need to go back to an old backup for some reason. At that time, you will not likely need the old backups at all since you will have a current 2-3 month history of new backups. At that point, you can erase the USB drive and use it for another purpose.

How to restore machine using a TM backup on a usb hard drive from older imac to a brand new iMac?

My imac (the one that had a superdrive in it), had a broken superdrive and was sent for repair. Whilst being "repaired" the screen was broken. I now have a brand new imac albeit without a dvd drive. My question is how to I restore my the old TM back up which had been made to an external usb hard drive to the new imac. Help files say that I should not restore from a TM file to a different machine and that I should use migration assistant. Whilst I can see the external usb drive in TM it is not being recognised in Migration assistant when I click on back up from a TM backup on another machine or disk.
Any ideas?
Just noticed that this new machine is running OSX 10.8.4 the broken imac was on mavericks

This is very simple first run Software Update on the new machine and get your machine upgraded to the most recent version of Mountain Lion 10.8.5. Install all other software updates Apple recommends in Software Update. Then care fully read Pondini's guide on using Migration Assistant located at:
http://pondini.org/OSX/MigrateLion.html
Your migrated data will be in a new account, to access it log into the new account.
Also DO NOT repeat DO NOTuse Wi-Fi to migrate data, if your TM backup drive uses USB, then connect it via USB and follow the on-screen instructions as described in Pondini's guide.

Lion won't run from usb hard drive

I downloaded Lion yesterday. Took 7 hours, from 5:30pm to 12:30am. I bought a new 500GB USB hard drive to load it on. I had previously upgraded the SL OSX per instructions. The Lion install went fine. It told me to reformat the drive, which I did (to get rid of MS-DOS formatting). The Lion installer recognized the drive and went through a 20 minute install.
Upon restart, it defaulted to SL on my internal drive. I went to Preferences/Startup Disk and clicked on the "Mac OSX 10.7 on 500G HD" and clicked Restart. Again, it defaulted to my internal SL drive.
I restarted the computer and held down the Option key to pick a boot drive. When the window appeared, the external drive was not in the list, only the internal SL drive and the Windows partition for Parallels.
Repeating the above gets the same results.
I understand that the Lion installer is now gone and I can't install it again.
What do I do now?

The new hard drive is a Hitachi Lifestudio and it has one of those annoying "disks" that pop up on the screen wanting you to install some "Lifestudio" app. Erasing the disk and reformatting does not stop that message, so it must be in hardware.
It is. Return it for a refund and get the below.
I ALWAYS build my own drive (takes 5 mins). More storage and less money.
Use FireWire not USB.
USB is packet oriented and data transfer is managed by the CPU, Firewire is a streaming protocol and data transfer is managed by the CPU only to initiate transfer, after that, Firewire handles the rest dropping CPU load to nearly 0%.
Put the drive below, in the enclosure at the bottom. Note how the enclosure has a cooling fan, and that the drive is mounted on vibration mounts. I know of no other hard drive enclosure with those features.
A hard drive has three enemies 1) Heat, 2) Vibration, 3) A Windows 7 installation.

Accessing a USB hard drive connected to a AEBS from Windows XP SP2

Hi everybody my problem is this, I am using the AEBS. I have an iMac G5 and a Sony vaio laptop running Windows XP SP2. After some initial problems both connect to the Internet and if I attach a USB printer to the AEBS both allow you to print remotely however if I attach an external hard drive only the iMac can access it. The airport disk agent for Windows pops up that a disk has become available but when you try to access it you get an alert message that says, “unknown user, incorrect password, or login is disabled. Please retype login information or contact the disk’s administrator.” If you click on the preferences in Airport Disk, in Windows, no disk is visible although the disk is visible in the Airport Utility! I have tried different hard drives and all the different settings in the Airport Utility for accessing a USB hard drive connected to the AEBS and get the same message regardless. HELP1

Hi John,
My hard drive is already formatted to fat 32. If I "check disks" in AirPort Utillity in windows it see's the disk and knows how much free and used space there is on it. It also knows when I'm accessing the disk from my iMac but when I try to connect to the hard drive from windows I just get the error message in my first post. When I click on AirPort Disk in windows my base station name doesn't appear, it does on my mac. I tried you suggestion but it hasn't helped. Thanks anyway. If you've got any other suggestion i'll gladly give them a try.
Thanks again.

Note that you cannot just reformat the drive. You must re-partition the drive. Open Disk Utility and select the drive entry (the one with the mfgr.'s ID) from the leftside list, then click on the Partition tab in the DU main window. Select one partition from the dropdown menu. If you want to use the drive to boot the MacBook, then click on the Option button and select the GUID partition scheme from the dropdown menu. Click OK, then click on the Partition button. Wait for the volume to mount on the Desktop, then quit DU.

C30: Booting from external USB hard drive

I carry my OS on an external portable USB drive, and then make use of whatever hardware is available where I visit.
I recently attempted to boot a Lenovo C30 Thinkstation with this external drive, and was unable to do so. In looking at the BIOS settings, there is no option to boot from USB (other than floppy(?!?) or memory stick).
Is it possible to boot from an external USB hard drive, and if not, why?
jerry

The boot sequence section of our setup menus has been troublesome to say the least (at least through the development phase). There are various reasons why it is the way it is now....from spec requirements to customer requirements. So long story short it really needs to be this way, even though situations like the one you encoutered is inconvenient.
The USB issue is actually done for security reasons. For example, many large customers don't want users to have the ability to just walk up and plug in a USB device and allow the system to detect that and attempt to boot to it right away as it is a risk to their image/security. For this reason, USB devices don't automatically get added to the boot order, and must be added throught he setup menu if needed.
