Mac Pro :: External Formatted Drive Goes Blank When Internal
Sep 2, 2014
Okay so, I have an External drive that sat in a USB enclosure until the USB connection snapped off on the inside. I figured I'd remove the (SATA) drive and re-purpose it as an internal drive. When I did this, it shows up as unreadable. The drive itself shows up in disk utility apps, but the two partitions (one was a Time Machine backup, the other a regular Mac-formatted (Extended) partition, do not. I get the ol' "This drive cannot be read. Initialize?" message when the machine boots up. how I can get back to the data I know is on there? Am I gonna have to do a RESTORE to another drive?

Mac Pro, Mac OS X (10.7.5)

My bootable drive is a JBOD (concatenated array) of two internal disks. Therefore I cannot use Bootcamp. I have placed a third blank drive in the third hard drive bay. I have my download of the Windows 7 beta, which I burned to a bootable disk using Disk Utility (.cdr file). Now, might any of you in the audience be able to inform me of what I should do to get the Windows OS from the bootable disk onto the completely blank internal drive?

I just got hit with a double whammy. :Imac running Panther did something odd to the it's external drive. That was formatted fat 32. I plan to see if anyone in the nearby computer repair class can recover those files, but in the meantime (days!) the gremlin also hit the macbook, putting it in range of a spill. So now the only backups I have are on the second external drive formatted with a mac format on the macbook. This one was done with 2 partitions, one for Time Machine, one for the stuff I was yanking over from the other hard drive.
So now I find that Imac can't even SEE the second drive. (Not that I expected it to see or recognize Time Machine, just the other part.) My macbook is on downtime until it gets checkup/cleaning (with all mac places nearby apparently closed thru New Years and classes I need it for starting right after) Does anyone know a way to get "Ye Old Imac" to see the other drive? Is there a driver or something? I know it's very hard to find older software (most online sites don't go back past Tiger), but it is a mac format for goodness sake! I can't even be 100% sure if it's something to do with a newer mac format for the external drive or "Ye Old Imac" is just being grumpy. It seems to see the other USB stuff but it has been known to lose touch with them.

I try erasing it again and making sure it is formatted for MSDOS and still no luck. So I try partitioning and that is also no luck. 1 part for mac, other free space because no windows option was present

I'm running Lion on a Macbook Pro. It doesn't recognize one of my external drives that was used on my windows based laptop when connected via the USB cable. Is there a way to mount this external drive on a mac?Â

I've had a 1TB external hard drive for the last year and never had a problem with it until now. Suddenly, it is showing as read-only, however, it's formatted for Mac. Do I have to re-format it?

when I insert my 'FAT' formatted external hard drive (Samsung M3) into my mac book pro it comes up with the error message that says "the inserted disk is not readable by this computer" and I therefore cannot access the files. The story (potential further details):Â
1. I had a problem with my mac where it took hours to load each time I turned it on, would only work when power was plugged in etc. so I had to reformat my mac hard drive (when I tried to veriify it said repair, that wouldn't work). So i'm starting with a recently reformatted, clean mac.Â
2. Before doing this I reformatted my external hard drive (whilst on windows machine) to FAT32 (so I can use on both windows and mac) so that I could back up my files.Â
3. I then transferred files from mac onto external hard drive and then also put them on a windows machine.Â
4. After reformatting mac hard drive when I then tried to transfer files back onto the mac I get the 'not readable' error.Â

I just bought my first mac (yay!) and am trying to transfer my files off of my old pc. The problem is that I stored all my personal files on an external hard drive, which is of course formatted for windows. My mac will open it, but it is "read only." I tried plugging it back into my pc and using the Migration Assistant to transfer my files over, but it was not detected (rest of the pc was).
However, the second time I tried plugging it in to my pc, it told me it would need to be formatted first. Obviously my mac has changed something on it, and now all my personal files are on a hard drive that is unusable by either my old pc or my new mac!

My Seagate hard rive is saying that it is formatted NTFS when I plug it into my new mac. I have only ever used it on a mac and it didn't ever say this when i used it on my old computer.. Im not quite sure what to do because I have no where to put all my stuff to reformat it?
Also I made sure when I bought the hard drive that it was both windows and mac compatible...

I accidentally formatted my external hard drive when I was creating a Windows USB install disk with Boot Camp It was a HFS+ formatted drive with a GUID partition table and 2 partitions: one clone of my Macbook OS, and one with personal data. I'm not worried about the OS clone, I'm more concerned about getting my personal data back on the second partition.So far I've used Stellar Phoenix and Data Rescue 3. I reformatted the hard drive from FAT to HFS+ before I did these scans. Not sure if it was a good idea, but the programs wouldn't scan properly otherwise.Stellar finds my files with the original folder structure, but I can't open any of the files, even though the file sizes seem to be correct. Data Rescue partially finds the original folder structure, and also has a "Reconstructed files" section which has all my files sorted by file type and without the original file name. I really want to avoid going through all my photos, videos, etc. one by one to sort them out.
Can I still recover my files in the original folder structure? Why can Stellar find all my files basically intact, but I can't open anything? In the meantime, I'm going to try scanning with Disk Drill and FileSalvage with fingers crossed...

I recently bought a macbook pro and am making the transition from a pc to mac. It's all gone well so far, but I'm not sure what to do with my music. I currently have about 200 gb of music on my external hard drive (connected to my pc.) The internal hard drive on my pc does not have space to accomodate the files on my external.
I do not have the "Copy files to iTunes music folder" currently enabled because my internal doesn't have space. (And I like having the original music files in a separate location as I have over 30,000 songs). I don't know how to transfer my external and music to my macbook, since I will have to reformat the drive (which would erase everything on it, therefore I somehow have to make a backup either on my mac or on my pc. but what to do about the iTunes .xml file and iTunes folder on the internal pc drive??).

I just bought a 640gig Samsung 2.5 inch / 5400rpm drive and threw it in a FW800 case from Other world computing. Running some test using the QuickBench 4 and AJA system test shows me that this little bugger is almost as quick as my internal drive on my MacBook Pro (Model number: WDC WD6400BEVT-00A0RT0). How can this be???? I did a varity of test with different file sizes and the Samsung get 70 MB/s vs about 84 MB/s for the internal drive.
My internal drive is pretty full vs this external drive that is currently empty. I do a lot of video work / large gigabyte files on the drive so perhaps I have a defrag problem? I really expected my internal drive to blow the FW800 connected Samsung out the water?

I am considering buying an external Dvd Drive they all seem to have a max speed of 8x, as does my macbook pro drive.
I am currently in the process of ripping my dvd collection would I benefit from this? I assume I would save the internal drive a lot of wear and tear this way, but my need is for the increase in speed.

I had a Windows based PC a couple of years ago that had crashed. So recently i tried to put the files from my old hard drive from my Windows computer to my Mac. In order to keep track of what i have copied and what I haven't i thought it would be good to delete the stuff of my windows hard drive once it was copied. However, it doesn't let me delete anything of the Windows drive since it is set to read only. Is there a way around this? i've tried everything i can think of, but haven't found a soluti

New iMac (3.06Ghz Nvidia card, 4Gb RAM).I also got 2 Western Digital My Book Studio Edition external HD (1TB & 500GB).Now here's what happened.I installed my new Mac with the software I wanted and partitioned my internal HD to use SuperDuper Sandbox feature for the first time. After all that setup my system was running fine.Now I plug in my external HD's (via FIrewire 800, side Chained together), Leopard asks me if I want to use my 1TB for Time Machine (I say Yes), no to 500GB). My system backed up everything just fine, and I even tested Time Machine for the first time wich was kinda Fun.

I have a quick question that maybe you guys can help me with. I used to store all my music on an external drive, but now that I got a Mac I decided to just save them on the internal drive. When I select the External drive and Copy the files to transfer somewhere along the lines it gives me an error and pretty much the transfer Stalls(the transfer window stays open but nothing is being moved) and it wont close or nothing unless I restart. I really don't know what file is corrupt or anything, Is there a software I can get to make this process easier? I am trying to transfer over 100gb of music Via USB.

I think it will work, but if it won't, it would be superb if someone more knowledgeable than I could tell me so
Step 1:
Buy 2.5" external Firewire 800 hard drive enclosure
Buy 2.5" SATA drive (probably 500gb WD Black or something)
Step 2:
Whack new drive into new enclosure and fire it up
Step 3:
Clone my existing 250GB internal MBP hard drive to the new one in the enclosure using Carbon Copy Cloner etc
Step 4:
Remove new hard drive from enclosure and use it to replace the internal hard drive in my Mac
Step 5:
All being well stick the old hard drive in the enclosure and use it as an external

I have owned a Mac Mini for three years now (my friends convinced me to try the Apple way and this is my first Mac). The CD/DVD died just three weeks after warranty expired and Apple said (in essence) 'tough crap...you didn't buy AppleCare'.I have functioned without a CD/DVD drive since then, and everything was fine... until a week or two ago. We installed an update in iTunes, and everything started running S...L...O...W... So, we rebooted the computer! Instead of rebooting, it made the "bong!" sound and then a screen with an apple and a spinning wheel runs indefinitely. We let it run all night the first time and it stays on that screen for as long as you let it.

I started this situation with a bootable hard drive that I removed from a 4,1 (mid 2008) and a brand new unibody MacBook Pro. What I wanted to do was use Carbon Copy Cloner to clone the old drive to the new MBP. I used CCC to clone the drive to the new one and repaired permissions on the internal drive and tried booting from it. No Luck. I figured this was stupid to do and I could just use migration assistant so I decided to reinstall Leopard on the unibody. Unfortunately when I attempt to boot from the DVD it doesn't go past a blank grey screen. I also tried holding down option to open the boot manager and select the DVD, when hit enter over the DVD it freezes. The interesting thing is that when I connect the old drive to the unibody using an enclosure I can boot from the external drive no problem. I tried using another computer to install leopard on the unibody over firewire and the installation went fine but when I start the unibody it doesn't go past a blank grey screen. I am also positive the hard drive isn't damaged or anything because when I go to the boot manager after leopard is installed the internal drive shows up but when I select it, it freezes. I have tried resetting the PRAM, NVRAM, repairing the disk (which is successful). When I try to boot into single user mode the computer freezes when loading the text. Another interesting thing is that when do boot from the external drive it goes through verbose mode every time and I never choose to do that. Right now I am attempting to clone drive using Super Duper to new drive and see what happens.

Awhile back, I'd run out of space on my internal HD and transferred all of my content to a larger external HD. I don't remember "repointing" my iTunes Library (as you can do in iPhoto) but somehow, iTunes recognized this and has since been backing up and restoring my iPhone to/from it. Â
This however, has created quite a few problems (too numerous to mention) and so, having recently installed a larger HD in my internal, I now want to re-point iTunes back to it. Â
How is this achieved?

iMac, Mac OS X (10.6)
