External Hard drive problems

Quick note: The background on this involves a raspberry pi. However I am now working from my main rig, so the drive is now connected to my regular old x86 computer, which is why I'm not asking on the ARM bbs.
I've been using a raspberry pi as a headless NAS/torrent-box/media server/samba share for a long time now, and it's been great. However, I've recently had a bunch of power fluxuations. Most of my computer hardware is on a big fat surge protector, and the energy is further protected by a robust power supply. However my Pi NAS was not (my external drive was plugged into a surge protector though). It started going wonky, and I started finding some corruption in my data. Then it stopped working all together.
To make a long story short, there was corruption on both the SD card (/root) and the external (my samba share). I tested the SD card on my main rig, and although it was corrupted, the SD card was salvageable (I tested it by writing to every bite, then reading the data back and seeing if there were any changes with a program called f3).
Then I started working on the external drive. Plugging it into my main rig, dmesg gives:

(Let me know if you want me to filter that or give you guys more of it. It actually keeps spitting stuff out)
fsck just hangs when I attempt to run it on one of the partitions.
gparted hangs on startup if the device is plugged in.
I've read elsewhere that it could be related to the cable. Unfortunately I only have one USB3.0 cable, but if you guys think that it might help, I can pick one up at Radio Shack. What do you guys think?
By the way it was ext4

I haven't had a chance to crack it open yet, but:

Lastest Update 10.4.3 & External Hard Drive Problems?

My problems started 2 days ago when I could not copy new music to my ipod shuffle. I kept getting error "...could not be read from or written to..." I had run the new ipod update 1.1.3 so I restored to factory settings and used previous updater 1.1.2. Seemed to be fine for the time being. Later I tried to import music from a CD, wouldn't import, same message. Tried to download a song from the Music Store, same thing.
(For some additional info, I have 2 external hard drives. On hard drive One I keep my iTunes media, iPhoto media and a mirror backup of my Documents folder from my internal drive, and miscellaneous other big files I don't want to bog down my internal drive. My second external hard drive is just for digital media when running final cut pro. I dont' use this drive much. The first hard drive is not partitioned but the second one is and I noticed yesterday that only one partition was coming up.
I began to realize that my problem with iTunes was not with iTunes itself but a drive issue. I did a quick test and set the internal drive as the main drive to store iTunes music to and did a test download from the Music Store and it worked just fine. So now my problem is something related to perhaps the latest update to 10.4.3 and my external drives.
Just a couple things I tried this morning before I had to leave for work.
1)Tried to copy a file to the external drive one and it wouldn't copy. Got a message saying the file name was too long, which no matter how short I make the name, nothing will copy to the drive.
2) Tried to open a photo from the external drive in Photoshop and it wouldn't open.
3) Strangley, I can still just play music in iTunes even though coming off the same drive as the above issue #2.
4) General question. When I do updates is it wise to not have external drives turned on when updating. I remembered that I did have them turned on when I did lastest update.
Perhaps this is my error.
Anyone else having external hard drive issues, please send your ideas my way...
thanks

I did install the combo update 10.4.3 again and it helped one of my drives. Luckily it's the one I use everyday with my iTunes, and iPhoto libraries and all my other important stuff. The second drive that's partitioned into 3 parts still had problems. One more partition came back bur the third part I just couldn't retrieve and had to blank it. I also had an issue with a corrupt iphoto library and had to rebuild my library.
So I'm almost back up to having my problems resolved. I have also noticed speed issues. Things seem a bit slower since the update. I'll keep workin on it.

Time machine, finder save to external hard drive problems

I have a new 2.26 GHz mini and I wanted to get bootcamp going and install windows xp. The instructions suggested to backup the hard drive and I thought this is a great time to try the time machine. I plugged in a external hard drive, opened time machine (Time machine said it needed 29 GB for full backup and the drive had 32 GB free), selected the drive, and let the "backup count down(I think it was a minute and a half)" run down to zero. Time machine started backing up the my main drive to the external drive no problem. It was running good (100MB in 5-10 seconds) for a little while when I noticed that it had reached 2.3 GB and was not going any higher. I let it stay like that for about 5 minutes thinking that maybe it would start going again. No luck. I shut down time machine and saw a finder window with the progress bar behind it saying 2.3 GB. I push the stop button and it said stopping, but it would not stop and disappear like it should. I relaunch the finder and the icons on the desktop disappeared and would not come back. I relaunched repeatedly but they would not come back. Since the bar at the top of the screen would not come back I had to hold in the power button to shut down the computer.
Upon restart everything seemed to work fine until I tried time machine again and it would not work. So I tried to manually backup the files to the external drive. When I copied some files the little finder window popped up and said, zero KB of 290 MB, and would not change. I left it running while opened a browser and did a search for an answer to my problems. After about a half an hour I went back and saw that some files had been transferred. When I looked in the Activity monitor, I saw it was saving the files very slowly. I went to the finder progress bar and when I hit the stop button, it would say stopping but it wouldn't. I would have to relaunch the finder to make it stop. Then I tried to copy the files to a shared drive on my network and the same thing happens.
Before using the time machine both these drives worked no problems. I went to the shared drive computer and used that machine to copy the files from the mini. All files transferred no problems. So now I'm trying to find out what is wrong with my mini. It seems that it has to do with the finder since it effects both the usb and ethernet hard drives. All other functions work as they should. I don't know if anyone has had this problem after using time machine but any help would be appreciated.
Also I tried deleting my com.apple.finder.plist and relaunch the finder. No change.

That's much too small for your backups. Time Machine usually needs 2-3 times the space of the data it's backing-up (see #1 in the Frequently Asked Questions *User Tip,* also at the top of this forum).

That sounds like the drive is not formatted properly. See #C1 in the Start with the Time Machine - Troubleshooting *User Tip,* also at the top of this forum.
The other problems may have the same cause.
Most likely, it's set up for Windoze and not suitable for Time Machine. With only 32 GB free, you must have other data on the drive, so you probably can't erase it and reformat it for Time Machine.
Report back with your findings for the *Partition Map Scheme* and Format of the drive (per #C1), and we can figure out what to do next.

IMovie HD projects on an external hard drive problems?

I've recently been making a highlight tape for my football team. Since i dont want to take up that much space on my computer, I've decided to use an external hard drive. Making this project means taking DVD's that arent in the correct format and ripping them into the right format. I then save this onto the external hard drive. Then i import them into IMovie, cut the clips i want, and save it. I save it to the external hard drive. A couple days later I'll open the project back up, to continue work on it, and it wont work. I can see the thumbnails of all the different clips, and when i click on them, the monitor goes black and nothing plays. But, the weird thing is that some of the clips worked. 4 out of about 30 of the 5 to 10 second clips worked. Im wondering if any one has had problems with this and any suggestions they might have to fix it. Thanks!

Hi jwgoldsmith - welcome to the forum!
Are you sure that the external drive is formatted for Mac computers? It must be MAC OS EXTENDED, not FAT 32 or such. If you need to re-format, make sure you have saved important files to some other drive as re-formatting erases everything.

MacBook hard drive transform into an external hard drive problem

My macbook pro early 2008 just died. The mother circuit fried and well its not usuable anymore and the repair for it are like 900$. Having alot of data in my macbook hard drive , i ask the guy that work at the genius bar to take out of macbook hard drive.
then i install the hard drive in a enclosure kit to transform it into a portable external hard drive. My problem is:
It only read the Window partition info and doesnt even give the choice to view my Mac partition.
i divided my Macbook HD with bootcamp and i divided the window partition to only have 30 G and the rest (280g) to leave it for my Mac exploitation.
The HD cant seen to find my Mac partition and only shows the data i got on my Window partition, i was wondering wat can i do to get my HD to see the data of my MAC partition
Thx in advance for the answers

There are third party programs for Windows to read HFS+, and I won't promise anything, but a Linux LiveCD may work as well. I don't have any names off the top of my head for those third party programs, but google something like "Windows HFS+" and you should be able to come up with a few leads.
But in general, yes, you'll need a Mac to read a Mac partition.

ITunes on External Hard Drive Problem

I have moved my iTunes onto an external hard drive. Problem is I have to find original file every time I want to hear a track. Please help!!!!

Quit iTunes.
Move everything back where it was.
Open iTunes.
iTunes prefs -> Advanced. Make sure the iTunes musci folder location is set to where you want the music to be.
iTunes menu File -> Library -> Consolidate.
This will copy everything to the location you set in prefs and use that location for everything from now on.
The external must be on & connected before launching iTunes.

External Hard Drive problems with iTunes and iPod

I recently purchased a 320 gig external hard drive for my computer, hoping in part to load my iTunes library onto it. Obviously I'd have much more room on disc than my actual iPod, so I was going to manually manage my music (an option I didn't have selected on my iPod before).
I followed all the online help topics which have all been helpful so far. I organized my music files, changed my directory, consolidated my library, and now everything is on the external hard drive and is working just fine.
The problem comes when I connect my iPod. iTunes barely even seems to recognize my iPod all of a sudden, saying that it has been corrupted and needs to be restored. When I try restoring it, nothing happens, and I can't seem to do a thing about it through iTunes. Of course, there's actually nothing wrong with the iPod at all, since it still works fine and plays music exactly the same as before. It simply won't update or do anything at all when hooked up to my computer.
I know this has something to do with the new hard drive, since everything was just fine a few hours ago, I just can't figure out why I can't get my iPod to sync all of a sudden. Like I said, my iPod is working fine otherwise, iTunes is playing music through the external hard drive without any issues, and I haven't touched any files other than music files (I haven't even deleted them off my original hard drive yet, so all the original fines remain unchanged, even though I switched the directory).
To the best of my knowledge, all my software is up to date, and the iPod is a 30 gig photo. Any ideas?
pc Windows XP

Yeah, I gave the new drive the letter Z, so there shouldn't have been any conflicts there. I also tried your other suggestion, and while the computer recognized my external hard drive, it didn't seem to make any difference once I plugged in the iPod again.
I've been wrestling with this for days now. I've tried changing the drive letters for both the external hard drive and my iPod several times (but no matter what, the iPod always seems to take F when it's unplugged and then plugged back in). I've tried restoring the iPod on multiple occasions. I've tried reinstalling all my USB drivers. I've consolidated my music library on several occasions (I now have two identical libraries on my external hard drive), yet annoyingly, iTunes seems to keep switching file paths away from the external hard drive and back to their original locations on the C drive. I'm trying to free up internal hard drive space, not house 30 gigs of media on it. That's what this new external hard drive is for.
Somehow, I was able to get them both to be recognized at the same time, but it never lasts long. I'll start iTunes with the external hard drive disconnected, plug in my iPod, wait for the iPod screen to come up in iTunes, then plug my external hard drive back in. Then, I can miraculously start to transfer music back onto my iPod, but iTunes doesn't seem to want this to happen for some reason, and will usually cut off the transfer. So far I've managed to put three whole songs on my iPod.
So now I'm trying to do two things. One, the same as before, get my computer and iTunes to recognize both my iPod and my external hard dive at the same time. And two, get iTunes to stop changing the file paths back to the C drive. These files are already on my external hard drive and don't need to change.
(As a side note, I should comment on how helpful people are on this discussion board. The Apple representitives I called on several occasions seemed totally unwilling to help, acting more like pushy salesmen than anything, while people here seem to be much more friendly and knowledgeable. Just thought it needed to be said.)

Aperture Export to External Hard Drive - Problem

I have a problem I'm hoping you can help me with. Bear with me here...I decided to backup my aperture library to an external hard drive, but I wanted to do so by exporting about 6 GIGS of RAW photos instead of using the vault.
So, I selected all the photos, clicked file/export masters and selected the external hard drive and the folder within that drive. An error occurred about 3/4 of the way thought the export, and aperture crashed. Now here's the problem: For some reason, my computer is telling me all the files that succeeded in exporting are taking up my HD memory, not the external drive's. When I look for the photos, they don't exist anywhere. They're not on the external drive nor are they on my hard drive. When I go back into Aperture and try to export a photo, it shows me the last export was to the external drive. It's baffling. It says the export was to:
mac/volume/externaldrive
Strangely, there is no such folder as "volume" on my mac.
So, now I've lost about 5 GB of space on my HD and I have no idea how to reclaim that memory. Does anyone know what could have happened? This is critical for me because I only have about 1 GB of space on my HD left.
Thanks for your help!

Oops...I meant to write that it's 60 GIGS.

Partitioning external hard drive problem?

I bought a new Seagate 120GB ATA/100 internal hard drive which I put into an Apricorn Firewire enclosure to create an External Hard Drive. The Mac initialized the drive and I used Disk Utility to partition the disk into 2 partitions, one for 70GB and the second for 50GB. When I clicked on "Partition", the Mac changed the size from 70GB to 55.9GB, essetially dividing the partitions equally, which is not what I wanted.
How do I correct this to get a 70GB and a 50GB external hard drive?
Thanks
Herschel

Rod,
Finally solved the mystery. Obviously, it would not be in the Help section, even though I had followed the directions exactly. Once I typed in the Size: 70GB, I then had to click on the left hand grey, partition box. At that moment, the box enlarged and the 70GB did not change in the Size window. How is one supposed to know to do all of that????
Anyway, it worked.
By the way, the Apricon Enclosures came and the setup was extremely easy. Took about 5 minutes and it was a Firewire External Drive. I got very good support, getting answers by email and phone in hours, not days. They are even sending me a cable that was missing. No Problem.
Now, I will work through the SuperDuper program. In corresponding with them, they suggested strongly that I Clone, and not Image the drive.
Thanks
Herschel

Another external hard drive problem

I'm sorry if this topic has been brought up before, but I did a search and could not find anything that could relate to my problem.
I recently purchased an external 2.0 usb hard drive for my Windows XP Pro computer. iTunes was located under My Documents/My Music. In order to start making room for my internal hard drive, I moved all of the music under My Music to my external hard drive but was too afraid to move the iTunes folder. The folder is currently located under My Documents.
When I click on iTunes, iTunes does not start up. I re-installed iTunes's latest version to no avail. Is there any way to fix this problem?

Sounds to me like it's failed. You may be able to pull the drive from the enclosure and connect it using a SATA-USB adapter. If the drive itself has failed, it may be possible to recover the data, but data recovery services are not cheap.

La cie external hard drive problem

just bought a new G5 mac pro after my old G5 gave up on me.
installed all the software and attached the external hard drive ( la Cie,I reformatted it for Time Machine ), scanner and printer.
In the first week had a few freezes and twice, after a long start-up, found corrupt files. The files that were corrupt were files that I worked on that day, not older files, of course also the files on my back-up Hd were corrupt.
After reading some threads I found that maybe the scanner or external drive could be the problem.
So detached those and so far no problem. My guess is that it has to do with the La Cie external hard drive. I don't have a serial# for that drive, but it is a design by F.A.porsche. I read that the drive has to be a FAT32 formatting??
Is there something I should do with that drive so it would work in a normal order?

Just to clear things up, the G5 was PowerPC and had "PowerMac" name. The Mac Pro is Intel only and only an outside resemblance.
You never want to migrate applications from G5 PPC to Intel, causes problems. Install fresh and avoid the pitfalls.
LaCie is really the most common culprit. Their power adapters, but also their poor cables - both USB and FireWire.
You don't mention, but just in case, don't daily chain; or mix hard drives and other types - get a separate PCI controller even.
TimeMachine must be GPT and HFS+ and there is no such thing as a case that must have Master Boot Record and FAT formatting.
Invest in Disk Warrior to handle disk maintenance - preventative.

Two computers to one external hard drive problem, pram reset...

I have a Powerbook 15" 1.0 Ghz and recently I made the mistake of connecting one external hard drive to two computers. My OWC External hard drive was connected to my powerbook via firewire 800 and my PC via firewire 400 with both on. There is a tiny little blurb on the external hard drive's instructions that says do not connect to more than one computer at a time but of course I didn't see that until after the fact. My powerbook was painfully slow so I restarted but it wouldn't come back on. I was instructed to reset the pram, which I succesfully did but now the powerbook is so slow it is unuseable. The pc works fine. Did I do any permanent damage? Do I need to reinstall OSX or what? I will kill myself if I fried something on my powerbook. Please help!!

Disconnect all devices from your PowerBook as well as power and the battery for about 30 seconds. Put the battery and power back in/on and then reset both PRAM (3 consecutive times) and the PMU. Hopefull this'll bring it back to life.
Otherwise, create a new user account and see if things are better there. It is possible that you have damaged software rather than hardware so a clean instal may do the trick.

External hard drive problem

I was trying to copy an imovie project (about 23 GB) to my external hard drive, but it stopped when it said that "The finder cannot complete the operation because some data in 'Clip 04.dv" could not be read or written. (Error code -36)."
Does anyone know how I can fix this? It stopped the entire copying, not just that one file.

Are the media files bad on the "original" drive? Is the external drive plugged into one of the rear ports? I know on PM G5's the front ports are fussy. Don't know about a G4 tower.

External hard drive problem, please help!

I have a SEAGATE external hard drive which I had associated with Time machine so its file system was HFS+ journaled.
when i turn the hdd on a window pop up comes on the screen telling me to either initialize, ignore or eject.
if i go to disk utility the hard disk shows as disk1s2 and that its format is FAT32.
trying to repairing it/fixing through Disk utility gives me the following error
Verifying volume “disk1s2”
** /dev/disk1s2
Invalid BS_jmpBoot in boot block: 000000
Error: Filesystem verify or repair failed.
however if i go to terminal and type fsck -f -y /dev/disk1s2
after a few fixes the following output was given
Andrew:~ Andrew$ fsck_hfs -f -d -y /dev/disk1s2
** /dev/rdisk1s2
Using cacheBlockSize=32K cacheTotalBlock=1024 cacheSize=32768K.

so here it recognises its name and everything.
what's wrong?
Thanks!

If you don't have any data on the drive, you may want to initialize the disk. Otherwise I would check out DiskWarrior.

Moved itunes to external hard drive problems

Hi
I am trying to clean up room on my laptop and followed directions on how to move my iTunes music to an external hard drive.....I did that and they are on that hard drive, but when I open up iTunes on my laptop, nothing is there and none of my lists, favorites, etc. are listed, just blank. I need to find out how to change it back, and start over I suppose.....if anyone can help and explain it in a really basic way, I would really appreciate it.....
thanks kindly

Time Machine & External Hard drive Problem

Alright so i recently had an issue with my Macbook. But i resolved that issue. Now when i plugged my usb back into my macbook it asked if i wanted to use it as a backup, and i said yes. But then it deleted over 50Gb of Photos/Work/Applications and all sorts of stuff.
This have basically driven me over the edge. Im here trying to troubleshoot it and cant seem to get it back to normal. I was hoping if anyone knew any way to fix this and find all my files that were on my external hard drive. Is there anyway to fix this? or any terminal codes that can help bring back my files?!
Please help!

Eject and dismount the disk immediately.
Your only hope to recover the data is via specialized Data Recovery software (or a service that does this). It's not cheap.
Search Google, VersionTracker.com and/or MacUpdate.com for software and/or services.
