Problem attaching USB drive to my TC

Hello all, I have tried searching all over the place and I can't seem to find anything that is helping me.
I have a 2TB USB drive that I recently attached to my MBP, formatted it Mac OS Extended (Journaled) and then proceeded to copy about 1TB of data to it. All is working great when it is attached to directly to my laptop but when I connect it to the USB port on my TC to try and use it as an additional network file system the TC flashes orange and tells me the "Disk needs repair". I put it back on my MBP and it still works fine.
Am I missing something here? I should be able to do this right?
Any help you could offer would be greatly appreciated.

thxceej, welcome to the discussion area!
Suggest that you connect the drive directly to your MBP, then open
Applications > Utilities > Disk Utility.
Click to select your drive on the left and then click Repair Disk at the lower right of the window and let the process run. It may take 30-60 minutes depending on how much data you have on the disk.
When the disk has been repaired, power down the complete network...all devices. Connect the drive back to the USB port on the Time Capsule. Then start the modem first, then your router,then devices one at a time until everything is powered back up.
See if that helps.

Disk Utility 13 problem with USB drives

There appears to be a problem with Disk Utility 13 (part of OS X 10.9). At least, so far as I can tell, everything traces back to this app, or possibly OS X 10.9 itself.
I recently upgraded my MacBook Air to OS X 10.9 (reformatted hard drive, installed system from scratch, updated with all the latest Apple updates). I pre-checked all my third party software to make sure it was 10.9 compatible before installing it after the system cleanup, so everything I’m running supposedly has been approved as safe for 10.9. But I’m seeing a problem formatting USB drives that I do not encounter when running under 10.8.
I have a Seagate STAA500101 (“FreeAgent GoFlex”) drive connected via Seagate’s USB3 adapter that I’ve used for some time as a Time Machine backup. Post-overhaul, I decided to erase the backup and start fresh. When I attempt to format it (single GUID partition) with Disk Utility, I see the following messages go by:
Formatting disk1s2 as Mac OS Extended (Journaled) with name Untitled 1
Could not mount disk1s2 with name (null) after erase
Then there’s a pause, and the format appears to conclude fine. But if I run a “Verify Disk” immediately, I get this:
Verifying partition map for “Seagate FreeAgent GoFlex Media”
Checking prerequisites
Checking the partition list
Checking for an EFI system partition
Checking the EFI system partition’s size
Checking the EFI system partition’s file system
Checking all HFS data partition loader spaces
Volume on disk1s2 has 0 bytes of trailing loader space and it needs 134217728 bytes
Problems were found with the partition map which might prevent booting
Error: Partition map needs repair because a data partition needs loader space.
As the drive has just been formatted, that seemed odd. I took it over to another Mac still running 10.8.5 and formatted it there — it worked just fine. Verified just fine. Took the drive back to my MacBook Air and tried to verify the disk — same failure.
I wanted to rule out bad media, so I took a Lexar 16GB USB flash drive and tried to format it with Disk Utility 13 — got the same problem.
The only success I’ve had formatting USB drives under 10.9 is to boot up into OS X Recovery. Disk Utility there formatted my Seagate drive without an error. But once I booted back into normal 10.9 operating mode, the drive once again fails to verify; it makes me leery about using it as a Time Machine backup.
I suppose it’s possible there could be some background component like Sophos causing problems when formatting drives, but if I format a drive via OS X Recovery or another Mac under 10.8, that wouldn’t explain why the drives fail to verify.
Anyone got any other observations on this issue?

Problem resolved. I'm posting this note for anyone else who might run into this situation and come across this discussion.
It actually did turn out to be Sophos -- Cloud, that is. I'd been using Sophos' free Mac antivirus software on a variety of systems but forgot that I was now testing out Sophos Cloud on my own MacBook, which is their new endpoint solution, and supposed to be compatible with OS X 10.9 (although the Mac version is listed as "beta") Sophos Cloud includes a new feature called Device Control which allows you to create a company-wide policy to control access to hardware such as USB drives, optical drives, etc. But apparently it's still pretty buggy. I had my Device Control configured with the default setting of "monitor but do not block" but it was most definitely gumming up the system. With Sophos Cloud installed, here's what happens if I try to run "Verify Disk" on any attached drive. Note on the left side how "disk2s2" shows as a sub-volume for each hard drive.
So if I uninstall Sophos Cloud, reboot and rescan, here's what I get:
Works fine. Note that the "disk2s2" subvolumes are also gone. This is the way Disk Utility also appears on a 10.8 or 10.9 system, even if you have the standard free Sophos for Mac software installed. It's only Sophos Cloud that's not playing nice. It also appears to have stopped me from being able to play DVDs from an attached Apple USB SuperDrive -- that problem was likewise solved by removing Sophos Cloud.

Attaching USB drive causes EX4 to become unresponsive.

Hello, I have tried to setup a usb to nas backup a few times and keep having the same problem. Upon attaching the 4TB usb drive (usb 3.0) to the back of the EX4 the NAS becomes unresponsive. I can no longer access it from the dashboard or the my cloud app on a mobile device. The app says it is offline. The ex4 is on but no drives are spinning. The usb drive is spinning however.
Once, I was able to see the EX4 and the attached USB drive in my file explorer. It showed the USB drive as a share. It said something like "Share 2_1." However the internal folders were not visible. Then the EX4 froze and went unresponsive - which caused me to try and manually shut it down. It did not power down and after making sure no data was being transferred I had to pull the power (as recommended on this forum).
Once I was able to get as far as setup up a USB to NAS backup on the dashboard. I set up the source and destination folders, etc. upon saving the job the EX4 is inaccessible, while the USB drive spins.
What's going on? Is it taking a long time to index the attached drive? Is it not compatible with the USB drive (seagate 4tb external NTFS USB 3.0)?
Any insight or advice would be great. Thanks!

By default the EX4 will scan the attached USB share for media. This process takes all the CPU of the EX4 for long periods of time, and can also lead tot he creation of numerous metadata directories in your attached drive. You should turn this off. In addition, if you use the USB drive for backups, the DEFAULT option for the EX4 is to commence backups when the drive is connected. This setting can be turned off in the GUI setup for the backup jobs. In addiiton, in my experience, NTFS drives take more overhead than EXT formatted drives.

Can't access the Time Capsule Drive and attached USB drive

I bought the 3 TB Time capsule a couple of months ago. I am using it as my wireless router for a cable modem and have attached a USB drive (seagate) to the TC. I use the TC drive for time machine only. It worked well at first, for about the first month. Now I have trouble accessing the TC drive as well as the USB drive. The router function works perfectly fine. The drives show up in the Finder under Shared but cannot connect. Time machine does not back up because it says the back up drive is not available. In disc utility, the base station shows with the correct name, but I can't access it. It asks for a pasword but does not respond, so I cannot reboot it from my computer.
If I restart the TC (power off and on), it works fine, I can access both drives. However, this problem recurs, sometimes within a few days. I have also noticed, which may be related, that when I enter time machine (when everything is working fine), some of the back-ups are blank. There is a date and time but no actual back-up. Not sure if this is related.
I'm runing Mavericks 10.9.2 on an older MacBook, 15" late 2008 with 2.4 ghz dual core.

Hi Bob,
I updated Mavericks but still had the same problem, so I did a hard reset on TC, although I held the button for over 5 seconds and the amber light was flashing rapidly, it acted like a soft reset. Still no change so I rebooted my laptop. Still had an excellent internet connection but in AirPort utility, the TC is grayed out and says device not found. Light on TC was amber. So, I tried a hard reset again, but the light wouldn't flash at all. Unplugged it and after pluggin back in, acted like a hard reset. I restored previous settings and it is fine for the moment. Will keep you posted if it recurs. Hopefully it will not with updated Mavericks, but I get the feeling the problem may be the TC.

AEBS Erratic behavior when connecting to attached USB Drives in XP

I have the old 10 100 version of the AEBS. I have always had problems with connecting to the attached USB (3) drives on a powered USB adapter. I have spent hours on the phone with Apple Support and eventually Apple released new firmware for the AEBS. This seemed to correct the connection problem for my iMac under Leopard. The AEBS does show in the Finder and I can connect to it with no problems. When I use my XP pc, the story is entirely different.
There seems to be several problems and maybe someone can help me with this.
Every time I shut down the XP machine, I have to remap the drives to letters X. Y, and Z. At times I am simply asked for the password to the AEBS to connect. At other times I have to disconnect the mapped drives (they no longer work but still show in explorer) then remap them again. This will work some times but most of the time I will get a message saying the network connection is unplugged (this is the AEBS restarting as I no longer have access on my iMac) and the mapping process will fail. This should be a simple process and I should be able to access the 3 drives either by mapping them or going through the network connections in Explorer.
Does anyone know why this process of mapping drives on the XP machine would keep restarting the AEBS? Is there any way to permanently keep the connection to the AEBS 3 hard drives when I reboot the XP machine?

I would also like to do this, but in the meantime, here is my question for you: How did you connect multiple hard drives to the AEBS? Did you just use a USB hub, or did you successfully link the two drives? I have one enclosure that has a USB, and that one is connected and working with the AEBS, but i would like to connect another one also, but it only has FW ports. I tried to link the two together with FW, but the FW HDD isn't showing up. I would be willing to get a new enclosure for that drive, if I was sure it wold work through a hub...

Will Time Machine backup Time Capsule files to an attached usb drive?

Hi Everyone,
I want to put shared media files on my Time Capsule and then have Time Machine backup my imac and all the files on the TC to a usb drive attached to the Capsule. Possible? That way I have a shared media server that is being backup up regularly.
Thanks for the help!

No. Time Machine cannot backup any network attached storage device such as TC. TM can only backup a Mac's internal HDD plus and ATTACHED/LOCAL HDD to the external HDD connect to the TC USB port.

Problem with USB drive not writing/freezing on unmount.

I have a sandisk cruzer blade USB drive, which I have used for the past hours extensively. At one point, I couldn't manage to write data to it. It acted like it had, but it didn't, as it silently remounted as readonly. I solved this by remounting as rw and retried.
Now, when using the same drive, after writing around 2 GiB worth of data to it (creating files), and attempting to unmount, the unmount command freezes for a long period of time. I check dmesg and it says its frozen. So I open up another tab to try and rescue the writes I made by typing sync. This also freezes and generates dmesg messages.
As I'm typing this the commands seemed to have succeeded, but I'm wondering, what causes these problems? Is the problem known?

Limited how? Like all storage devices have (in other words, after a while they break)?
The drive is completely new, like 3 weeks or something.

Problems mounting USB drives

I am having some problems getting USB flash drives to (auto) mount on my system.
In the past, when I plugged in the device (a simple USB flash drive), it showed up in Thunar and I could click on it to mount it. Now nothing shows up in thunar when I plug in the device. dmesg shows the following, so I know the device is being recognized:
usb 2-2: new high speed USB device using ehci_hcd and address 14
but it isn't being assigned to /dev/sd*. fdisk -l also doesn't show the device. lsusb shows the following for the device:
Bus 002 Device 014: ID 0781:b6b7 SanDisk Corp.
I added a udev rule to automount in /media, as per the udev wiki instructions, but that didn't do anything. Installing udisks and udiskie was similarly unhelpful. I tried this with multiple USB drives (which I both confirmed were working on other machines) so it doesn't seem to be a HW problem.
Thanks in advance.

You might try reformatting the usb drive using Disk Utility. Use MacOS Extended(Journaled). That might help.

Attaching USB Drive - Can't read AP configuration file, kills internet

Current network:
Airport Extreme (Sim Dual-Band)
Mac Pro (wired Ethernet)
MacBook Pro (wired or WiFi N)
MacBook (WiFi N)
2 x iPhones (WiFi G)
Airport Extreme in use for several months with no problems. All Macs can read/write it's configuration.
I hooked up a 1TB My Book USB HD to the Airport Extreme via USB. All three Macs (Mac Pro, MacBook Pro, MacBook) could see and read/write to the new drive. The Airport Extreme appeared in Airport Utility on all three Macs. Wired, WiFi N + G internet continued to work great... however none of the Macs could read the configuration file of the Airport Extreme. If I unplugged the USB drive all the Macs could read and write to the configuration file.
I plugged the USB drive back in and left it overnight. This morning, everything continued to work, with the exception that none of the computers could read the configuration of the AP.
Around 10am today the Macs/iPhones could no longer connect to the internet. I disconnected the USB drive and now the internet works again.

How to set an attached USB drive to automatic sleep using Airdisk?

Greetings all!
I am looking for a way to set my two USB drives to sleep when they are not being used. I only use them a few minutes a day, and don't want to run them down or use the electricity to keep them spinning.
It seems there has been some discussion about this but I haven't been able parse all the conversations. Some people seem to have gotten it to work, while others are relying on a drives "internal" mechanisms. It would be great if someone (perhaps at Apple?) could chime in with an overview of the problem.
Perhaps it is linked to the method of authentication - ie., (using Airport Utility 5.1), whether the Disks > File Sharing > "Secure Shared Disks" > is with "disk password" or another method?
Some have suggested a radio button for a future firmware/other update such as:
"Set drives to sleep when not in use" (Let's hope for this!), but I am hoping for a simple solution in the near future.
Any thoughts out there?
best to all.
*NB: I first posted this on Posted: Apr 4, 2007 12:23 AM and got NO response at all - hopefully I'll have more luck this time !

Hello Andy,
Thanks for your reply.
1. For using Microsoft Outlook rules, we need to keep the computer on, even after work or the colleague is on leave. That is not allowed in my company.
2. For sending an auto-reply email based on subject, that is impossible because the emails from customers are different and we don't have a basic standard.
3. Could you please elaborate how to set a transport rule in Exchange server to achieve the goal?
Thanks a lot in advance.
Steven
1. Only client rules require that the Outlook client remain open. An auto-reply rule should be server-side, so no need to leave Outlook open.
2. Yep!
3. Walk through the hub transport rules and you see one that replies with a rejection code. Thats the best you can get with a hub transport rule and not something I would recommend in your scenario. You could also search around for 3rd party solutions.

Sharing an Attached USB drive on Network

I have an intel Mac Mini on a network. I would like other machines in the same subnet to see the Mini Pal USB drive I have attached to it. All I have managed to access from the other PCs is the main drive via the home folder.
This is trivially easy to do this on my XP machine. Am I just dense or is it not possible on the Mac?
Thanks for any guidance you can lend.
- Dave -

I hate mysteries, so sooner or later I'd like to find out how to set those attributes "manually".
Sharepoints is a GUI and you can see how it manipulates the netinfo database when adding new sharepoints.
You can also see what it writes to the windows sharing config file /etc/smb.conf
This will give you an understanding of how to this manually. However it is by far easier just to use sharepoints. Or if you invest in professional server software you can use the workgroup manager.
BTW could you mark this thread as solved as it helps other users who search the forum find specific answers. Thanks.

Help Problem with USB Drives

I connected two USB drives to my MBP yesterday and all I was doing was transferring files from one USB drive to the other. One of the USB drives in the middle of the transfer would disconnect for no reason and the transfer would freeze. I tried to do the same thing on my 12 inch PB G4 running 10.4.11 and I had no problems transferring files with no freezing. Does anyone know what might be happening. Thanks for your help.

Weird... It happened to my old MBP. I brought it to the Apple Store (I had some other issues too), and they replaced the logic board and it was fine afterwards.

Attach usb drive to time capsule

I have been attempting to SEE the HD attached to the USB port on the TC. It DID work previously until I had to factory reset the TC. Now, it doesn't show. Any suggestions?
I've been to the Disks tab and the File Sharing box is checked.
Stumped.

Plug the usb drive into the mac.. can you read it??
Plug it back into the TC.. if it disaapears it can be due to USB drawing too much power.. TC is severely underpowered.. and even a powered disk can have issues.
It can be firmware update that happened. If the TC is now on 7.6.3, go back to 7.6.1 or even better 7.5.2
It can be format of the drive.. if it won't show in the airport utility it won't show in the computer.
Retry with a USB hub.. make sure the disk is formatted HFS+ and partitioned using GUID type.

Can I attach USB drive to Airport Express USB port

I would like to attach a USB drive to my Apple airport Express USB port so that I can back up my data on my MBP and have my music stored on it for playing back over Apple TV.
Is there any issues to doing this? As an example, how would I see the drive?
thanks in advance.

Well, you can certainly attach a USB drive to the port on the AirPort Express.....but nothing will happen if you do this....since the USB port on the Express will only support a compatible printer and Keyspan remote control.
You will need an AirPort Extreme if you want to attach a shared hard drive to the USB port.

Permissions / Sharing - Problem with USB Drives

Hi,
I suspect it's possible to do what I want, but not via the "easy" route. I'm very new to OS X, so hoping there's some more advanced functionality I haven't found yet.
This is what I want to do:
I have a USB drive connected to a Mac Mini running Snow Leopard. I have two users setup - one admin, one normal. I want only the local admin account to be able to access the files on the USB drive. I want the admin account to share the contents via the local network with my (Vista) laptop (which is setup with the same username / password as the admin account).
Problem I have is that whenever I try to apply any permissions to the USB drive, they are ignored. From what I've found on the internet, that is "by design" behaviour.
Are there any ways around this that people can suggest? Scripts? Other utilities? Other settings hidden away somewhere?
Beyond that, ideally I'd like to encrypt the whole drive as a TrueCrypt partition, mount the drive automatically when the laptop is detected (using a keyfile stored on the laptop), and then only let the laptop access the drive. But I'll accept a simple solution for now!
Thanks,
David

select the external drive in finder and enter command+i. in the resulting popup unlock the lock and uncheck the box to ignore ownership on this drive. permissions won't be ignored now. give your admin user read+write permissions to the drive and remove them from everybody else. that should do it.
I don't use TrueCrypt and can't comment on that.
