Accessing FAT32 external USB Drive via web server for streaming of content

Hi all
I've read a post about streaming music from my mac via wifi to my iPhone 3g.
It involves enabling the webserver, adding a symbolic link to my music directory and then browsing to the webserver using safari on my iphone.
I've enabled the webserver, added the symbolic link however when I try and follow the instructions to add permissions to the music folder I get no error however browsing to the folder I receive a "Forbidden" message saying I don't have access.
A friend of mine who knows more about Mac's than myself (macmini is my first mac) has suggested it's because my external drive isn't part of the core system???
Has anyone else seen/tried this with an external drive setup?
Regards
Wayne

here is the link to the post/instructions I'm using...

I ran the chmod command successfully (no error's in Terminal) but still cannot view the contents of the directory via a browser
Cheers

Single-user mode: How to mount and access an external USB drive?

My MacBook Pro HD is acting up. Cannot boot normally or into "safe mode". Cannot reinstall OS without wiping out the HD. Need to recover some critical files but DiskUtil First Aid and Restore options cannot successfully complete. Problem traced down to "invalid node structure" which means I either have a hardware problem or my filesystem partition directory structure is corrupted. I need to recover some files that are not backed up (timin issue with my regular backup process).
I can boot into single-user mode, mount the root file system (/sbin/mount -uw /) and can see/navigate the rot filesystem structure via good UNIX command line. Here's what I would like to do (in single-user mode):
1. Mount an external USB drive (250 GB already formatted as Mac OS X Extended)
2. Copy various files and/or directories from my HD to the external USB drive (UNIX cp command)
I realize I could go spend $$ for the Disk Warrior or Data Rescue products (or something similar) that SHOULD help me recover my HD or files, but it seems silly to do this when I can see, touch and taste them from within single-user mode....
Comments? Suggestions?
TIA --
Trent
P.S. Once I've recovered my files, I'll try to reformat the HD and then reinstall the OS. And THEN go have Apple look at my machine (thank goodness for AppleCare coverage)!

Resolution:
1) Boot system in single-user mode (SUM) with external HD attached.
2) Execute the following UNIX CLI commands once SUM boot process is completed:
# fsck -fy
# mount -uw /
# mkdir /Volumes/target_directory
# mount -t hfs -w /dev/diskXXX /Volumes/target_directory
# cp -RXv /source_directory /Volumes/target_directory
Where XXX is the device-level name for your external HD's data partition. In my case this was /dev/disk1s2. It may take some experimentation to identify this device name if your system has multiple HD's.
3) Verify contents were successfully copied onto the /Volumes/target_directory.
Comments and observations:
- Do NOT use "/" as your source directory - cp will make a second (redundant) copy of /volumes/target_directory
- I was able to successfully copy ALL files off my HD despite the fsck command's "invalid node structure" error message with this simple procedure. YMMV, depending on the state of your HD.
- The repeated disk0s2: I/O error warnings displayed during the SUM boot process did not seem to have a negative effect on this procedure. I also received this same error warning intermittently as I navigated the mounted filesystem did not seem to be a problem, either. Again, YMMV.
Commercial software:
I downloaded ProSoft Engineering's Data Rescue 3 product (trial version) before spending $99 to attempt to recover my "bad" HD's data via mounting to a good system with FW target mode. It could not successfully complete its "QuickScan" process and immediately hung on block 0 of 390M during its "Deep Scan" process. The product did seem to function properly on an operational system. ProSoft's technical support was responsive and helpful but had no answer for my "Deep Scan" error.
I did not attempt to use Alsoft's Disk Warrior 4 product. I could not find any trial software available and was reluctant to spend $100 based upon the mixed reviews and comments on this discussion forum as well as other reviews. Alsoft does claim to address the "invalid node structure" error in their marketing materials. Hindsight being 20/20 - I saved $100 by using this simple procedure.
Final note:
Neither Leopard nor Snow Leopard's installation DVD could recognize the bad internal HD when trying to do a reinstall. While DiskUtil was able to "see" the bad internal drive it immediately failed when I tried to do an "erase and format". Took the system to my local Apple store and the Genius ran a tool called "SMART Utility" from Volitans Software (www.volitans-software.com). SMART utility confirmed that my HD was bad so it was replaced. AppleCare pays for itself (once again!).

Can't access folder on a TC drive via web server

Here's the setup:
I got a MBA (10.6) as a simple web server sharing files to a remote computer via VPN. For this, I created a symbolic link to the folders I want to share and dropped it into the root user's library/webserver/documents.
The remote client accesses the folders via web browser with the internal IP (192.168.xxx.xxx/"folder") of the host (I know, there are fancier ways to do this, but that's how I've been doing it so far).
Now, I wanted to relocate some of the folders to my TC drive. I did so, however I got an error message saying 'Forbidden, You don't have permission to access xxx on this server'. I tried to change the access permissions of the folders in question on the TC, but no avail.
I couldn't reach them from the local net either.
Anyone here, who knows how to solve this problem? Put it another way, is it even possible to access the TC that way?
Any help is appreciated.
Thanks!

Thanks for the answer, but it was not the solution I have been looking for.
I found a provisional workaround installing MAMP. Dropping the symlink folder in htdocs did the job. However, I'd be glad, if someone out there knew how to do this on the native OS X Apache, since running an additional server is pretty bothersome.

Backing up to encrypted disk image on an external usb drive

I'd like to use an encrypted disk image on an external USB drive as the target for my Time Machine backups, but it seems that Time Machine will only recognize physical external drives, and not mounted disk images in the "Change Disk..." window.
Is it possible to make Time Machine use disk images mounted from an external USB drive?
Thanks.

..."Is it possible to make Time Machine use disk images mounted from an external USB drive?"...
Actually, with a few caveats, it is possible.
Just follow one of the many tutorials on the web for creating an encrypted sparse bundle for use with "TimeMachine" on a network volume (i.e. MACaddress.sparsebundle naming convention, password stored to the system keychain, etc.), and then attach the drive locally and select the drive (not the mounted disk image) as the backup drive. As "Glen Carter" reported in another thread on this site, "TimeMachine" is smart enough to know to mount the disk image for backups when the drive is connected locally.
There are caveats for example, - while backups remain automatic, it appears that actually browsing the backups requires that the disk image be mounted manually first, then accessed via the "Browse Other Time Machine Disks…" option.
One caveat to pay particular attention to is what happens when the drive starts to fill up and space becomes limiting - the processes of deleting expired backups and sparse image compaction may not be well integrated, as discussed here:
http://www.flokru.org/2008/03/15/time-machine-backups-on-network-shares-2-possib le-problems/
The article implies that the end result could be deletion of all backups! The article is dated March 2008 but I have no idea whether the issue has been resolved.
Just be advised that it is an unsupported configuration so the extra security will come at the cost of some convenience and potential increase in the chance of data loss. Most users recommend using supplemental backup strategies since the intended purpose of TimeMachine is actually very limited and often misunderstood. Apart from that, it is a rule written in stone that whenever encryption is used, the encrypted items themselves must be backed up.

Time Capsule external USB drive won't reconnect remotely over Back To My Mac

I'm running a Mac Mini at work, connected via ethernet to an enterprise network (I have no idea what routers they are using, or how they are set up).
At home, I have a MBP laptop and a Time Capsule (hardwired to cable modem) with an external USB drive attached.
All 3 machines (Mac Mini, MBP, TC via Airport Utility) have Back To My Mac switched on.
I can access the external USB drive on my home TC from my work Mac Mini....until the Mini falls asleep. When I wake it back up, the connection back to the TC fails. However....after restarting the Mini, the connection works again.
My first thought was that the corporate network / firewall / etc was causing the problem - not leaving correct ports open, or someting to that effect. However, I realised that if that were the case, restarting the Mini shouldn't help, but it does.
Does anyone have any idea how sleeping breaks being able to access a TC's external drive remotely over BTMM?
The Mac Mini is a 2.3GHz Core i5 with 8GB RAM and plenty of HD space.
The MBP is a 15" late 2013 retina, 2.6 GHz Core i7, 16 GB RAM, also plenty of HD space.
The TC is a 2 TB 4th generation model.
Thanks!

Sorry that did not work. This works well for me using Lacie drives, but I haven't tried Iomega.
Have you checked Iomega's site to see if any software/firmware updates available?
Also noticed during a quick search that a number of users are reporting mounting problems with Iomega. Not sure if this applies to you or not.

Make Time Machine use a specific amount of space on an external usb drive

I have 1tb external usb drive which i use for backup with TM. I want to set TM to use only 200GB space so I can always have 800GB available on the drive. This way I can prevent TM to keep backups that are too old and exanding backup data to all of the disk because when there is only 200GB available old backups are removed automatically. How can I do that?

Find good info here.

Unable to access external USB drive on my windows machine

I have an XP SP2 box with several partitions. I Just purchased a MacMini (fisrt time apple user). I have joined the maac to the same workgroup as the XP box and can access all the partitions on the XP box with no problem. With the exception of the C: drive and the External USB drive.
I have the drive at Fat32 and can connect directly to the mac with no problems. Read, write all works fine. connect back to the XP box and I get an error -43. It ask for a user name and password and knows if I use the wrong password. I can even see a list of shares on the sub folders of the external drive but get the error when I try to access.
Thanks in advance
Mac mini Mac OS X (10.4.4)

This could be a smart design inside XP. FAT32 can't store file ownership so maybe it refuses to share a FAT format drve? From a security point of view this would be the right thing to do. On the other hand it could be a bug in XP that just by dumb lock looks like it is doing the right thing.
Either way it sounds like you have a good workaround: put the drive on the Mac and let the Mac share the drive. It's best if the drive is reformatted for the Mac so that user ownership and permissons can be used.
Don't worry one computer can't know how another's dive is formatted. The network hides this. All my shared files are on EXT3 formatted drives on a Linux server. All the clients see is "SBM".

Trouble accessing files on external USB drive after 10.6.8 update

Upgraded to Mac 10.6.8 on my MacBook Pro (I'm not a techie, but the "About This Mac" thingy says 2.53 GHz Intel Core 2 Duo, 4 GB 1067 MHz DDR3 - I assume that means something to somebody). Since the upgrade, I've been having problems accessing data on an external HD connected via USB - there were no issues before the upgrade, but now it's impossible to even navigate to a particular file or subfolder half the time, as the process freezes 95% of the time (every so often I am able to get through, for no obvious reason) - usually I just get what looks like an empty folder and a little spinning thing in the bottom right-hand corner. Sometimes when I do get to a file - say it's a ZIP file - I'll try to unZIP it and the process will hang; if I try to drag it to the desktop and unZIP it there, I can't get it to copy to the desktop, I just get the "copying files" box and a bar that never shows any progress, it just hangs at zero bytes out of whatever it might be.
Also having intermittent issues with another external USB drive, which is the one I use for Time Machine - about one in every five backup attempts is successful, the rest of the time I get a message saying the backup couldn't be performed.
I have two external FireWire drives as well, and I'm having no trouble with either of those - so I'm assuming the problem is USB-related (and 10.6.8 related, since none of this was happening before the upgrade).
So - I'm wondering if anybody else is having the same issues, and f there's a solution that a non-techie like me could handle that won't make blood come out of my ears.
Cheers!

Thanks baltwo - the PRAM tip was helpful. For some reason I still have trouble accessing a few files, I'm putting that down to them being somehow corrupted. Eric, thanks, but I tried using Disk Utility and the communication problems I was having with the drive meant that the repair couldn't be performed. I may try again now that that side of things seems to be running a little more smoothly. Anyway, thank you both!

IMac using an external hard drive via usb 2.0

I am currently using a brand new 20" iMac with 4GB of ram and since this computer only has one firewire 400 port I'm using that for the deck and plugging in the external hard drive via usb 2.0, but I do have the option of plugging in firewire 400 to the hard drive. I've recently been having trouble capturing footage. Anyone have any suggestions? Thanks.

You're experiencing the number one reason why not to use an iMac for video work: complete lack of expansion beyond a couple of firewire devises.
Yet, many folks will disagree with this assessment and their decisions are made solely on cost over functionality and reliability.
Go iMacs!

Can't access external USB Drive

I have a Seagate external USB drive that I'm trying to access. This drive has not been used in awhile, but as far as I know it ok.
When I plug it into my G4, and power it up, it never comes up on the desktop. Instead, I get a message saying "the disk you have inserted is not readable by this computer", and gives me the choice of "initialize", "ignore", or "eject".
This drive has worked in the near past. Why do I now not seem to be able to access the data on it?
I tried a "restart" with the external drive hooked up, but get the same message. I really don't think the drive is bad.
Is there any way I can force the computer to recognize an external drive?
Note: System Profiler sees the drive, but it just never mounts.

Hi Japamac, good to speak with you again. You have helped me in the past.
Sorry for the repeated posts in multiple forums. I've been desperately trying to figure this out, and was looking for maximum views of my problem.
A couple of days ago, I was able to get this drive to mount making me believe that is (was?) formatted for Mac. Nothing that I know of has changed since then except that now the drive will not mount.
Disk Utility sees the drive, but verify disk and all other choices are greyed out. Clicking on "mount disk" also has no affect.
Under disk utility, I clicked on the "info" tab for the external drive, and under "Partition type" it says "WindowsFat32" but I don't know what might account for that if the drive is Mac formatted.
My primary concern is if the data on this disk is still ok. If it can still be accessed on a PC, I can get together with a PC owner this weekend.

External hard drive via usb. Can I use one?

I"m running out of memory. Can I use an external hard drive via a usb port?

You say "ripped" music. That is not stored on iCloud unless you subscribe to Match. As for iTunes Store purchases:
Downloading (using iOS or computer) past purchases from the App Store, iBookstore, and iTunes Store - http://support.apple.com/kb/ht2519 - enabled with iTunes 10.3 and newer; not all media formats are available in all countries (see: iTunes in the Cloud and iTunes Match Availability by Country - http://support.apple.com/kb/HT5085); apps, books (not audiobooks), music, t.v. shows, and movies (some - not all studios have permitted this). Downloading previously purchased movies and TV shows requires iTunes 10.6 or later. Discontinued items not available. For items not included in the iCloud list (e.g., ringtones, audiobooks), or locations or computer systems where iCloud is not (yet?) available, you only get one download per fee paid. Apple notes it is your responsibility to back up your purchases.
Select the iTunes Store on the left side of iTunes.
Click on Purchased on the right side under Quick Links.
You can re-download your available previous purchases.
Of course if you had a backup of your files you would have been back up adn running iTunes by the time you read all this.

External USB drive goes to sleep, iPhoto complains when it try's to access it and exits

I moved my iPhoto to an external USB Harddrive and everything at first worked fine. Now I get these errors sometimes "Your iPhoto Library is missing". iPhoto will exit and when you start it again everything is fine. What I think is happening is the external USB drive has gone to sleep due to inactivity. Is there a setting in OS X that I can control this with ? I ugly hack would be to set up a cron job to do a ls of the root external USB drive every 15min. Is there a special feature that you should look for when buying an external USB drive ? It is very iratating to get these messages from iPhoto and iTunes.
Thanks

Cannot access shared external hard drive with other mac accounts

I cannot access a shared external hard drive with other mac accounts (all accounts are on the same macbook Pro). The shared external drive is shared via time capsule and is connected (of course) in USB. I see well this external hard drive as a shared disk with my main account. Yes shared option has been activated with the Airport Utility .. but when I open other account these othe accounts can see the external drive but cannot access to its content that is flagged with a no way sign. Strangely enough when I close my main account and start opening a new session with one of the other account then fine I can access the external hard drive and its content .. BUT then it is from my main account than I cannot access its content the no way sign showing ..
Looks like only one account at a time can access the content of this SHARED external hard drive .. any one as an idea on how to really make it a shared hard drive so that all accounts on the same mac can also access it ? I am at my wit ends on this case. THANKS ..

Results of my enquiries at Apple Genius Bar .. the guys found the problem interesting. They've been unable to provide a fix neither to give any explanation as to the reason why. To be fair I was not much impressed by the technical level demonstrated ..
In the mean time I have found that if account no.1 can see the shared external drive content and in such case account no.2 (same Mac computer) cannot see its content (only the external HD with a no way sign) this account no.2 can UNMOUNT (by ejecting) this external HD from account 1 and then remount it (just clicking on the TC shared part in a finder window) and .. see and access its content ; whilst account no.1 cannot see its content anylonger. Unless it unmounts the shared external HD and remount it .. then account no.2 can see its content anylonger. This can goes on an on.
So eventually YES the TC can allow to share a USB external drive between several accounts and a same Mac .. BUT this require to unmount and remount EACH time the external drive is accessed from a "no.2 account". So OK to share files with seldom access but not practical in case of frequent access needed.
I just I have now to figure how iTunes can automatically unmount and remount a shared external HD when it needs to access one of this shared HD content from on time account no.1 and then next time from account no.2. May be I am asking too much ..

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...

Problems with a shared external USB drive

I have setup an external USB drive on my iMac 10.6 and use it for Time Machine backup. When I try to access this drive over my wireless network from my PowerBook 10.5.8 for TM backup, I can only see the drive under Shared as a Folder, not a drive icon. It is not available for the PB's TM app. This is a HP 1 TB drive formatted in 1 partition MacOS Extended journaled GUID .... and it works as a backup drive for the desktop 10.6 TM.
The very same thing happens if I connect this USB drive to my Airport Extreme only both the PB and the iMac see the drive as a folder and neither can use the drive for a TM backup.
So, how can I see the drive as a drive icon from the PB and have it available for TM backup over the network?

Do not attempt to back up that way -- it's "iffy" and +*not supported by Apple.+*
It sounds like you've missed a step in the setup. See #22 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).
Be sure to note the advice there to partition the drive, so each Mac has it's own, exclusive space.
