Wrt600n Deleting files or corrupting partion info on external hard drive

I have experienced this ordeal two different occasions and 2 different external hard drives. While in the web based utility setting up ftp access and networks shares and such the router has deleted or corrupted the partition table. My 1Tb WD external was nearly 75% full and after clicking save settings the files were gone. So I borrowed my buddies external to try to duplicate and I did however I'm not sure what exactly caused it to erase the drives. All i know is i plugged each drive in reset the router set up network shares the set up and turned on the ftp server and set ftp acces to couple accounts and wham info was lost.

It might be a firmware issue. Try reflashing its firmware. You can get it from www.linksys.com/download

File transfer from MacBook Pro into external hard drive

I can't copy files from the MacBook into an external hard drive.
In the 'Get Info' section, it says read-only. However, the hard drive have just been recently bought.
I had the same problem with our previous hard drive. Although the previous hard drive was 'read-only' I was able to copy and paste files in our old HP laptop.
What can I do in order to copy and paste files from the MacBook into the hard drive?
Hard drive = Toshiba
Capacity = 1TB

In my last paragraph, I said
"Note that Windows PCs cannot write natively to an HFS drive, so if you need to exchange files between Mac and PC, we need to talk about different options."
Windows cannot read Mac Extended (HFS) formatted drives; the Mac cannot write to Windows (NTFS) formatted drives.
The only formats fully compatible between Mac and PC are FAT32 (largely deprecated) and exFAT. If you need full read-write compatibility between Windows and Mac, and you can erase the drive (ie, it's a new drive or you have confirmed backups), reformat to exFAT using Disk Utility.
If you have a drive with files on it and you cannot erase them at the moment:
- if the drive is formatted for the Mac, you can purchase MacDrive for the PC
- if the drive is formatted for Windows (NTFS), you can purchase Paragon NTFS for the Mac.

I'm having some difficulty with Time Machine. It appears to be deleting backups from random dates on my external hard drive. I am not deleting them. Are they hidden and how do I prevent this from happening? Can I retrieve them?

I'm having some difficulty with Time Machine. It appears to be deleting backups from random dates on my external hard drive. I am not deleting them. Are they hidden and how do I prevent this from happening? Can I retrieve them?

... I didn't know that Time Machine was more a last resort back up instead of main back up.
Don't rely upon Time Machine to the exclusion of all else. I compliment Time Machine with a periodic "clone". TM is much better than nothing, but it's a safety net, not a hammock
Here is my understanding of Time Machine's file deletion algorithm, distilled from Pondini's FAQ, Apple's KB articles, and my own observations.
Time Machine deletes ("thins") files from the backup disk as follows:
Hourly backups over 24 hours old, except the first backup of the day
Daily backups over 30 days old, except the first backup of the week
Older backups get deleted when Time Machine requires space and you deleted them from the source disk.
Therefore, assuming TM has been performing at least one backup per day, backup files will remain available:
at least thirty days, if they existed on your Mac for at least a day
until you run out of space, if they existed on your Mac for at least a week
In addition to the above, Time Machine always keeps one complete copy of your source disk so that the entire volume could be restored if necessary. Any files that remain on your source volume will be present on the TM backup, no matter how old they are.
If you are using 250 GB of space on your source disk, its Time Machine backups are likely to require at least twice that much. A good estimate of the minimum required backup volume size would be about three times the size of your source disk - 1.5 TB in your case.
A more thorough explanation would require Pondini since he has plumbed Time Machine's mysteries far more than I have.

Downloading files from PC to Mac via external hard drive

I have already downloaded the files from my PC to an external hard drive. I have connected that external hard drive to my iMac and am attempting to bring those files onto my iMac, but don't know how. Can anyone help? I have it connected, but it seems to be showing up at my Time Machine Backup and I can locate any of the files from my PC.

Hi and welcome to Discussions,
here are several ways to migrate your PC files http://support.apple.com/kb/HT2518
but it seems to be showing up at my Time Machine Backup and I can locate any of the files from my PC
I am not sure if I understand that one correctly.
Does your external harddisk comes up as a Time Machine backup in OSX ?
Or is Time Machine asking if you want to use that external harddisk for backup ?
Regards
Stefan

More information would help. How is the external connected? Does the external appear on your Desktop? Has the external been formatted for a Mac? What method do you use to transfer files? When you try to move a file to the external, what does happen?

I cannot get files from my desktop to my external hard drive

Does anyone have any information on why my external hard drive would not be allowing me to move files from my computer to my external hard drive? I have a Seagate Free Agent external hard drive. It has 1TB of space that is no where near being used. It will show up on the desktop when I plug it in, but i cannot move anything to it. Also, I have a few movies on the external hard drive that I cannot view for some reason. Does anyone have any input on why that could be? It gives me the pop up window that says "a required codec isn't available." Any onformation will be very helpful. Thank you in advance for your help.

How do I export video files from iPhoto to a backup external hard drive for safekeeping?

How do I export video files from iPhoto to a backup external hard drive for safekeeping? Each time I try, the video will not play from the external hard drive.

Use the File ➙ Export ➙ File Export menu option with Kind = Original. That should get the original video file exported. Try to export one to the Desktop first and open it with Quicktime Player. If all goes well export the rest to a folder on the EHD. How is the EHD formatted? It should be OS X Extended (journaled).

How can I change the source file so it is direct from external hard drive?

I am trying to make a movie on imovie of a snowboarding trip that I went on, there is around 80 to 100 gig of mp4 movies that will not fit on my computer that I have stored on my external harddrive. I had the movie half finished then found I could do no more as I had no space left in my mac. I had to delete everything and start again but I'm not doing this until I can find a way of changing the source file so I can take them direct from my external hard drive as to not use up all my computers available space. I have moved imovie to my external hard drive but it still tries to read from a movie file on my mac, how can I change that so it will read from a source file on my external hard drive, is it possible?? Can someone help me??

Hi Bengt, Thanks for your input, much appreciated.
I have a WD 1TIG hard drive and are using usb connection, is it possible to use fire wire with these? I have had trouble with a lot of the videos I Imported, once they downloaded the file in the viewer window showed up blank and when I mouse over them it places a picture of another file in the window and wont drag and drop into the movie window, like their corrupted or something? Had to delete just about all of them and start again. Also is it possible to select a bunch of videos in the viewer window as to change the dates to the correct dates? All I have been able to do is "select all" which is no help.

Files copied (backed up) on an external hard drive can NOT be opened

MacBook Pro (2.5GHz, intel Core i5)
OS X Yosemite, 10.10.2
I was running low on storage space on my Mac Pro. I copied all items on Desktop to my external hard drive. After all files were copied from MacBook Pro to the external hard drive, "get info" suggested that the amount of space taken entirely was the same between when all items were on the Desktop and when they were on the external hard drive. The number of items copied over were also identical. I should have been more careful, but I then deleted all items from the Desktop. It was until a few days later (today) that I noticed majority of the files copied over onto the external disk can NOT be opened now. The error message was "The alias “<filename>” can’t be opened because the original item can’t be found.".
I really don't want to lose these files, but where are they? They got their file sizes correct but just can not be opened. I tried copying these files back to Desktop on my MacBook Pro, that's not helpful. I tried accessing the files on a PC, still can't open the files. I tried repairing disk of the external hard drive (under Disk Utility), still can't open the files. I tried repairing disk permissions of my MacBook Pro hard drive, still can't open the files.
One last thing I tried in terminal (I am not terminal savvy at all, just googled the "The alias..." error message and copied the instruction): /usr/bin/SetFile -a a /Volumes/MAC This did not solve the problem, either.
Thank you for your help in advance!

Hi, eddie from pataskala ohio.
We love pro-active thinking here at the Apple Discussions and you're off to a great start.
Even though upgrading iTunes shouldn't affect your Library, one of the funny things about computers is that sometime, somehow, somewhere when you least expect it , they can do some not so funny things, like losing data that they're not supposed to. Which is why it's a good idea to have a back up copy of any data (such as your music) that you value in reserve ... just in case.
The most straightforward way, is to go to the iTunes Edit menu > Preferences > Advanced tab > General sub-tab and make sure your iTunes Music folder is assigned to its default location: C:\Documents and Settings\User Name\My Documents\My Music\iTunes .
Next make sure all your music is stored in that folder by using the iTunes Advanced menu > Consolidate Library option.
Now you can copy the entire iTunes folder - the iTunes Music folder and the iTunes library files in particular - to your external drive.
If anything does go wrong with the upgrade, you'll be all set to recreate your Library.

I moved files off my computer to an external hard drive now time machine won't back up like it used to. It says there is not enough room.

My hard drive was completely full (mostly with pictures) so I moved several years worth of photos from the hard drive to an external hard drive I regularly use with the laptop. (Basically my master copies of all my photos back to 1997) I have always had Time Machine set up to back up both the laptop AND that external drive. It's always worked seamlessly until I moved those files. Time Machine has been full for a while now and regularly gives me a message that the oldest files will be deleted. That's fine.
I don't understand why moving files from the laptop to the external hd would now cause the following message (not an exact quote): Time Capsule cannot complete backup. You need 233 gb to backup and time capsule only has 107 gb available. If time capsule was already set to backup up both the laptop and the external hd, why would moving those photos from one hd to the other cause a space issue? It should equal out. And now when I look at the files on the time capsule, it only shows me a recent backup and a partial incomplete backup. None of the older backups are visible anymore. I have not deleted anything directly from the time capsule so I'm thinking somehow the index got damaged. How can I fix this? The error message says to change the settings but I really don't know what settings to change. Help!!

It does not immediately delete the files that are missing.. it merely tries to backup the new files it has discovered on the external drive. Since you moved the files there, the backup at least for a while will contain both copies.. and that is why it doesn't have enough space to backup.
Fixing the problem.. hmm pondini is the expert.. you should be able to delete the backup of the photos in existing backup.. there are instructions to do it.. but it is a very poor way to do things.
Much better. .archive off the existing backup.. this is long and slow but worth it. you need a usb drive of the same size as the TC drive. Then erase the TC and start a fresh set of backups.
The alternative is to use the USB drive as a new target.. but it is much slower than the TC internal drive.

How do i move a file from my mac to an external hard drive?, how do i move a file from my mac to an external hard drive?

how do i move a file or folder from my mac book pro to an external hard drive? the hard drive is formatted just for the mac.
i backpacking and taking loads of RAW pics so i need to get them off my mac onto the hard drive. it seems i have to copy them, only some times then some pics dont work!!!!!!!! pain in the arse!!! im quite new to the mac and loving it, but on the old p.c it was easy as!!!!!!!!!!!! help please

You just drag them and drop them where you want them to go. If you don't want to keep the original on the source drive, you'll want to delete it afterwards.
What do you mean "some pics don't work?" Don't work how?

Hi, Question about secure empty trash. I moved some Time Machine backup files to the trash from an external hard drive. Now I can't secure empty trash. It starts, finds 74,003 files, and does nothing. The external hard drive shows it's empty, but it isn't

I moved some time machine backup files from an external USB hard drive to the trash. Tried secure empty trash. It counts 74,003 items, then just sits there. The external hard drive window shows it's empty, but the info pane says it only has 50G of memory left. I left the secure empty trash on over night. It did nothing. Ideas?
Thanks,
Ron

Relaunch the Finder, then from the Finder menu bar, select
Finder ▹ Preferences ▹ Advanced
and uncheck the box marked Empty Trash securely. Try again to empty the Trash.

How to share files between pc and mac via external hard drive

how can i share my files(mp3,mp4,documents) from my harddisk with mac. i am a new mac user and i have a harddisk of NTFS format(as i was a pc user).I learned that mac supports FAT32 format and therefore i can't write data on my external hard drive.
but, reading a section of OSX yosemite(under compatibility) it is said that now we can easily share files between pc and mac.
So please suggest me easier way that how can i share files between macs and pc as my friends uses pc and in future i really want to share my data with them without any hustle and i dont wanna loose my data in future

You can format the HDD to a common one like ExFAT or Fat32 but a reformat will delete all data off of the HDD.
Your other option is to use a third party software such as Paragon or Tuxera that will allow you to write to a NFTS formatted HDD.
Ciao.

I'm attempting to transfer files, address book, etc from an external hard drive to my new Mac-mini using migration assistant. The external drive is showing up on my desktop but Migration Assistant is not seeing the drive when searching for devices

I'm attempting to migrate files, address book, maile, etc to my new Mac Mini using an external hard drive and Migration assistant. I followed the instructions on using Migration Assistant to do this but Migration Assistant is not seeing the external drive, which is displayed on my desktop

I've been chasing this problem all afternoon. I had to reformat my internal drive on my MBP and reinstall Mountain Lion Start up assistant wouldn't see my extrnal drive with the Time Machine files on it. After many tries, I skipped the restore there and let the system boot. I could see my external drive from Finder and the files looked OK. I was told to use Migration Assistant and it had the same problem.
I saw a hint on one of these posts that the icon that you see and is label Macintosh HD is actually your backup disk and it is telling you that it has a copy of your internal Macintosh HD. I went ahead and told it to continue and it started to restore my apps, settings, and documents. It's been going for a couple of hours, and is close to being done. I expect to see my old system restored when it is finished.
Wish that Apple would put some type of note that it is seeing the backup. That is most confusing and seems to be a problem for lots of users.
It's been a month or so since your post Did your get it to work?
