USB Hard Drive corrupted - twice!

ever since my recent (and otherwise very happy) transition to macs i've had trouble with an external USB hard drive which i use to store my music collection and back up. first there were issues with not recognising the drive for ages but these were fixed by a new case and then, more recently my drive has been corrupted - twice.
first time i immediately assumed it was because the drive was two years old and had travelled quite a bit with me so i replaced it with a brand new spanking one. however, two weeks later the exact same problem occurred. all data lost. osx recognises that the drive is there, and it's name but the folder structure is gone and replaced by some garbled charachters that start 'USB£@$@%£$%' or similar.
first time this occurred i was in the middle of some file transfers and the drive itself started making a few strange noises. second time was during the nightly back up i have running with superduper! at the same time as downloading stuff. i have the drive partitioned - 100GB osx extended format for the back up and 200GB fat32 for my music colleection. in the recent manifestation it doesn't mount the back up partition, but mounts the music one. i can see the back up partition in disk utility greyed out and it agrees that there is a fault, but it can't find any problems with my music partition - which now has no data on it.
i am completely at a loss here and my last few hour's research on the net have yeilded no results so if anyone can help i'd be very very grateful. i connect the drive through usb hub and to the left usb port if that makes a difference. i had absolutely no problems with a similar set up on my windows laptop for years. is it something to do with how os x handles external drives? or should i get a new case/usb 2.0 hub? all tips appreciated

i do use unmount - but what if finder crashes in the middle of an operation, which may have been what happened first time, and even the second time (but i wasn't around to see what happened), would that garble the folder structure entirely?
i live in the heart of a big city in the UK in a (relatively) modern building and haven't seen any power failures at all (resent alarm clocks etc) or are you talking about some level of super-quick fluctuation i've never noticed before? or did you mean something internal to the drive casing or something?
no error messages related to the usb hub so far. all other devices connected though it work just fine - ipod, printer etc.
the first drive was a hitachi, the second a western digital. the casing was bought from maplin and seems pretty generic - though both problems have occurred since i got the new casing which was about a month before i got my MBP.
it's a serial drive and i have no idea about the jumpers. first time i put everything together, but the second time the drive failed, i bought the replacement drive from the IT guys who were doing the data recovery (which didn't work) and they put it all together for me.
this doesn't have a fan, which the old one did, though it does have a metal casing - do you think heat build up after prolonged heavy use could cause problems?

USB Hard Drives Keep Disconnecting or Not Responding

Hi,
This is a long post - but one that I hope someone can offer advice on.
The Hardware
Mac Pro running OSX 10.8 (but this has happened on all versions of the OS i.e. 10.6/.7 etc)
3 x Internal SATA Hard Drives - All working perfectly.
External Drives:
2 x Western Digital My Book 1TB USB Hard Drives
1 x Seagate 750GB Hard Drive with USB2 connectivity
2 x IcyBox Dual Bay USB2 hard Drive enclosures using JMicron Chipsets - these enclosures have 2 x 1TB Western Digital Green in each (totaling 4 TB across the 2 enclosures).
D-Link 7 Port USB2 Hub
The Problem
- USB Hard Drives connected to the Mac are ejected from the system without notice and at random times AND/OR
- The external hard drive remains mounted, but when trying to write to the drive/partitions, Finder throws an error message up saying the operation cannot be completed - error code -50.
- Time Machine: TM will back up successfully several times, before eventually throwing an error up that it cannot create the folders required on the drive.
- The only way to be able to use the drives again is either remount the drive, or in some case, it is required to completely power the drive down and then reconnect.
Re-creating the problem
I have honestly not found a sure-fire way of replicating the problem. It seems completely random. It happens when I am actually sat at the computer, but it also happens when I am away from the computer.
In the past - my Time Machine hard drive has been one of the Western Digital MyBook drives. I also used the second MyBook for SuperDuper backups (extra redundancy). The 4TB drives in the IcyBox enclosures have been used to backup my ripped movie collection.
Recently however - I decided to have 2 of the 1TB drives in the IcyBox enclosures to be TM and SuperDuper backups. I have however reverted TM back to one of the Western Digital drives, purely for testing purposes. SuperDuper is backing up to one of the 1TB drives in the IcyBox.
I am trying various things to see if I can find the issue, but it is such a random event that it is taking ages to even come close to find a problem. Sometimes the drives will stay active for a few days, sometimes only a few hours, even minutes.
Theories
I have several theories as to why my USB drives continually disconnect.
1. The D-Link USB Hub.
Could connecting the drives through the hub be causing the problem? I don't really see how, unless it is a documented case that D-Link USB hubs do not play nice with OSX? To try and rule this out I have connected the current Time Machine back up drive (Western Digital MyBook) directly to the USB port on the back of the computer. The SuperDuper (IcyBox enclosure) drive is currently connected through the D-Link hub. I have removed all the other drives from the enclosures - so at present I have only 2 external drives connected (1 x 1TB Western Digital MyBook, 1 x 1TB Western Digital Green inside one of the IcyBox dual-bay enclosures - connected through D-Link Hub).
2. JMicron Chipset
I have done a bit of research on the internet and there are a few indications that perhaps JMicron SATA-to-USB controller chipsets found in a lot of external hard drive enclosures (including the dual bay IcyBox external enclosures that I have) do not play nice with OSX. If the JMicron chipsets in the 2 IcyBox enclosures is a problem - would that cause issues with other USB devices on the USB bus off the Mac? (i.e. can the JMicron chipset in the enclosures cause devices such as the WD MyBook drives which I assume use a non-JMicron chipset, to experience similar failures?)
3. Green Hard Drives
As I have said, I have 4 Western Digital Green 1TB hard drives inside the IcyBox Dual Bay Enclosures. Could the fact that these drives are 'Green' be causing a problem? They do go to sleep after x number of minutes, but they do wake up when required. But could on the occasion when I have problems, could this be caused by the 'Green' feature interrupting OSX in waking the drives? Coupled with JMicron chipset, could this be compounding the issue?
Possible Solutions
I am prepared to spend money on replacement drives and/or enclosures etc - but I would hate to spend x amount of money and have the same problem. So I am hoping to get some advice on what drives/enclosures are more than likely to work flawlessly with OSX.
Thanks for reading!

FYI - re: the SuperDuper drive that is in one of the IcyBox enclosures.
I just opened this drive up in Finder. I heard the drive wake up, but when I came to copy a file over (tried various file sizes) - I got the error -50 message.
Here is the info from Console.

TM on 2 differnt usb hard drives

I thought I had come up with a great back up plan:
1) I have one usb hard drive at work where I run TM every hour.
2) Once a week take my computer home, connect it to another usb hard drive and change TM preferences to run on that disk.
3) When I get back to work, I change my TM preferences back to the original usb hard drive.
4) Expected result: I then have to separate usb hard drives with back ups of my computer, one which have been run every hour and one at home which have been run every week.
Now I realized that every time I change the TM preferences to run on another usb disk TM will start from scratch and do a completely new TM back up. This means that I can not restore any old files with TM.
Have I misunderstood something? What should I change to get the expected result as described above?
thanks!

First, it should do a new, full backup only if you've gone several days (at least 10) without a backup to that disk (apparently, you can go longer if there weren't a lot of changes); done a full restore (maybe); or renamed your internal HD.
Second, TM will not delete the last backup to make room for a new one. It will fail for lack of space, instead. So you should be able to restore old files as long as those backups remain. That's why your TM disk should be at least twice the size of the data it's backing-up (and preferably 3 times).
But remember, if you created a file after the last backup to one disk, and deleted it before switching back, your only backups of that file are on the other disk.

Setup of USB Hard Drive on Airport Extreme for Time Machine

Hi all,
I upgraded to Mountain Lion a while back and am running the latest Airport Utility. Here's the problem: I can't get Time Machine to work anymore with my USB Hard Drive attached to my Airport Extreme. Is this setup no longer possible under Mountain Lion? Do I have to buy a Time Capsule? For the last couple of years I've had two MacBooks backing up with no problem to the USB drive connected to the Airport Extreme. Any advice would be appreciated!
Thanks,
Chris

While you can do this as Kappy points out, there a few details that you might want to consider before you make the move.
1) Time Machine backups to a drive at the USB port of the AirPort Extreme are not supported by Apple. While this does seem to work for some users, others (like me) have difficulty with corruption issues. The bottom line is that this is not a reliable method to back up your important data....and, no support or help from Apple if you do have difficulties.
Reference this Apple Support Document to confirm:
"Time Machine can’t back up to an external disk connected to an AirPort Extreme......"
http://docs.info.apple.com/article.html?path=Mac/10.6/en/15139.html
2) If you move the iPhoto library to the hard drive attached to the AirPort Extreme....your original or master library now resides on that disk.....and you have no backup for the library.....when, not if.....the drive has a problem.
3) You might want to post in the iPhoto forum to ask if it is still an iPhoto requirement that only one user at a time can have iPhoto open with the shared library arrangement.

LaCie d2 195 GB USB hard drive and new iMac

Has anybody had a problem with a LaCie d2 drive that is connected via USB instead of FireWire? I have both types of external hard drives; the FireWire connected LaCie has worked flawlessly, as has a Seagate 300GB FireWire drive. But my poor little LaCie 195 GB USB hard drive bit the dust when I tried to copy my iPhoto library from it to the hard drive of my new iMac Intel Core. The entire Mac froze up, even though there was disk activity on the LaCie. After waiting for 25 minutes for the Mac to unfreeze, I finally manually powered down the system. Unfortunately this corrupted my LaCie disk, and it could not be repaired using Disk Utility. Even when I tried to repartition the drive, Disk Utility simply hung to the point where I had to do a Force Quit to get out of it.
I forgot to mention that I was connecting the LaCie through a powered USB 2.0 hub - that could be a source of the problem, but it worked flawlessly in my iMac G5. I did reconnect it directly to a USB port on the iMac, but still could not get Disk Utility to repartition the drive.
Luckily I had a secondary backup of my photo and music files, or I'd really be crying right now.
Any thoughts?
Thanks,
JD

When I try to direct my iTunes library to my USB hard drive, it stays in 'connecting' status. Why?

I have an airport extreme that has a USB hard drive. I had my iTunes on my MacBook pro directed to the hard drive. It stopped using the hard drive and now I can't direct it to the hard drive. The Airport utility can see the hard drive and I didn't change any set ups. I have tried powering down and powering up the Airprot extreme. I have tried disconnecting and reconnecting the hard drive.
My husband was able to see the hard drive on his PC lap top and now he can't either. When he tries to connect the hard drive directly to his PC, it asks him to reformat the drive, which we don't want to do (won't that erase everything on the drive?)
What should I check?
Thanks...

Thank you for your response. I have done this...when I open the iTunes folder copied from my old computer, each song appears only once. When I open iTunes each song appears twice. Should I uninstall the iTunes folder from my old computer and reinstall it? It make no sense that I have 2 of everything in iTunes. Thank you for responding - I really appreciate it, as I don't want to have to delete each duplicate song

Application to scan and repair hard drive corruption?

Hi, my 2nd internal drive ran out of space and I'm afraid that there was hard drive corruption. Some of the video icon's weren't showing up and when I click on the video to play I kept getting beach balls. it seems to be better now but is there an application that can detect if there's any hard drive corruption? thanks

The hard drive seems to be ok now. I have 90gb's of free space on it. What do you think happened to it?
I couldn't say. But 90GBs should be plenty of free space to work with.
You might launch Disk Utility and check something though:
You will notice that the drive appears twice int he sidebar of Disk Utility.
The upper listing is the physical drive itself and it's controller. Highlight it and note what is reported at the bottom of the window beside "Partition Map Scheme". If this drive is only going to be used on your Mac, then it should read "GUID Partition Table"
Now highlight the lower listing in the sidebar. This is the portion of the disk platter devoted to storing your data. What is reported at the bottom of the window beside "Format"? It should read "Mac OS Extended (Journaled)".

Try using this article to help with your iPad not showing up in iTunes---
http://support.apple.com/kb/TS1538 -This deals with the device not being recognized in iTunes for Windows
The following steps work well with iPod but i would try them for help with your iPad issue:
Try connecting your iPad to another USB port directly on the computer. Verify that you're connecting it to a high-powered USB 2.0 port on your computer to be sure iPad is getting power. If you're connecting to a Windows laptop computer through USB, connect the laptop to a power outlet before connecting your iPad. Also, see iPod not recognized when connected to Windows laptop over USB to be sure that your USB ports are supplying enough power.
Avoid connecting to an external USB hub. If a hub must be used, make sure the hub is USB 2.0, and that it has its own power supply. Also, make sure the hub is connected to a high-power USB 2.0 port on your computer.
If the issue persists, try disconnecting other USB devices from the computer such as printers, cameras, scanners, external hard drives, and USB hubs to determine if there is a conflict in the USB chain.

USB Hard drive problems after sleep/computer inactivity

Hi
I am the proud owner of a 2009 iMac after making the plunge and switching from my PC.
I am using my old Freecom 3.5" Classic 1TB external USB hard drive for extra storage and have reformatted one of the partitions to Mac OS extended (journaled) for use with time machine. i have left the other partitions in NTFS mode because I occasionally dual boot into windows. I have noticed that when I put the iMac to sleep and reactivate it or leave it unattended for a while the external drive powers down and cannot be recognised without switching it on off & on again. Sometimes the drive icons disappear from my desktop and other times they remain but without any icons inside the finder window when I open them. I also get the warning messages about not ejecting the drives properly and am worried I corrupt the data on them.
I have done a quick bit of research and have found that other people have described this problem with various brands of USB drives, however I can't find a definitive answer!
Does anyone have one? Your help would be much appreciated!
Thanks in advance!

I have the same exact problem... I know other people have the same issue; I've done research on the internet and we're not alone. Just no response from Apple or suggestions from anyone else. I find myself just mounting the disk as needed to eliminate the possibility of losing any data. I then use disk utility to remount when needed as opposed to shutting the drive down.

Can't see contents of USB hard drive connected to Time Capsule

Hi. I have a USB hard drive connected to my Time Capsule (which I just got today). I just want to use it as a shared drive, so that the users in my home can use it to access common files (media files, stuff like that).
The TC's set up is to enable file sharing with accounts. AirPort Disk Guest Access is not allowed.
When I authenticate as a user via Finder I can see the disk, see that disk space has been used, but can't see the contents. I'm guessing this is because the files that are actually on there belong to some other user.
Is my guess right? Any suggestions as to how we can all use it as a transfer drive?
Col

Fixed it. I connected the USB drive directly to my computer, and dragged the folder into the 'Shared' folder, which Time Capsule had created. The original folder is now visible, which is what I wanted!

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 use iPad (4th gen) to edit with iMovie - but using an external source such as a USB stick or external USB hard drive

Want to use my iPad (4th gen) to edit a movie using iMovie - easy enough if the movie file is on the iPad - but what if it's too large - can I keep the source file on a USB stick or external USB hard drive and edit from there? How can you do this?

You can't export any type of file using the camera connection kit, so a USB flash drive or SD card won't work.
There are some wireless external hard drives that can be used with the iPad.
The Kingston Wi-Drive, which costs $50 for the 16 Gigabyte, and then $30 more for every 16 gigs more. It works by you turning it on and then accessing the files on it from an app that you download on your iDevice. You can access music, movies, and other stuff. No connections or anything, it works like a WiFi connection, you connect to it from the setting on the iPad under wireless networks.
Then there is the Seagate GoFlex, which some would recommend over the Wi-Drive. But this one costs $199 and had 500 Gigabytes of storage. It works the sameway as the Kingston: no wires, runs over its wireless connection. You can actually fit up to 300 HD movies on it.

Trying to use usb hard drive off extreme via ipad and iphone as a media server to go on my boat. My aim is to have the express with hard drive to have all my movies and music on it and use ipad, powerbook and iphone to control this through apple tv to my 42 inch LCD tv.
I am pulling my hair out here. Have purchase new Xtreme and plugged in a usb hard drive and think I have set it up properly as I can see and mount the hard drive on my powerbook and play videos etc via wifi (also conected to the internet) . Also when I have the xtreme and drive mounted on my mac I can access and play the media on the xrpess server on ipad via app called quick explorer.
Problem is that it seems to be picking up the xpress usb drive via the powerbook as when I shut down my powerbook I can see the usb drive but it keeps on deniying me the permission even though the passwords are correct.
Does anyone know if there is a correct way of setting this up to work or if there is an app or does apple have a way for their standard players to pickup the usb drive and control the media via iphone or ipad.
VERY FRUSTRATING

Can I set up multiple usb hard drives- one for time machine and a second for media? Can one also print wirelessly with an old HP C6280 printer?

Yes.

Possibly by using an Airport Express, but depends on what type of port connection the printer requires.

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.
