I have a 1 terabyte seagate external hard drive that I used to back up my PCs and tried to connect it to my Macbook Pro to transfer the files over from my old computers, but the Mac won't recognize the external hard drive at all. Any suggestions?
The drive also draws power from the wall. I don't have any other external drives to test it with but it does work for my printer when I connect via USB. Also, I'm relatively certain that my computer is up to date with all Apple updates.
I am having the same issue. Seagate replaced my 500gb drive and it is still not recognized by my Macbook Pro. Can you guys let us know if there is an issue with macbook's compatibility with the Seagate Hard drives.
Jumping into this thread to say I've run into the same problem--my WD Elements 1TB drive works fine on Windows computers (I've tried a few), but my Macbook Pro won't even pick it up at the I/O level. I'd reformat the drive if I could only get my Mac to recognize that the darn thing exists, heh. Any suggestions appreciated...
I have the same problem. I have been using an external hard drive for a few months now and all of a sudden my Macbook has stopped recognizing the drive when I plug it in as I always correctly had done. It says TimeMachine is Delayed. My last back up was Oct 2, 2010. I have tried restarting my computer with the drive attached and with it not attached. Still does not recognize it. When I say recognize I mean it does not show up on the desktop and the time machine application cannot see any attached drives.
Any help is appreciated.
Thank you
I have the same problem where the system has suddenly decided to stop recognising my USB drive. until recently all my backups were on this drive, now it cannot find it???
What is going on? was it the latest software update??
How do I get it back?
Please help
Just thought I let you know, i reformatted (deleted ) the drive sacrificing previous backups and immediately the drive was recognised by my system and the icon appeared on the desktop.
I believe that the last upgrade to the mac software is the culprit that made the drive disappear until reformatted.
It may be a price to pay to reformat but at least you get the drive back and can do a new backup.
Hope this helps

i too have a wd external hard drive.
i lucked out and my mac recognized it so i got my files off. but now the mac is not finding now.

"Just thought I let you know, i reformatted (deleted ) the drive sacrificing previous backups and immediately the drive was recognised by my system and the icon appeared on the desktop."
system being mac OS?
are you saying if you wipe the WD mac will recognize it?
I have had the same exact experience. Time Machine suddenly stopped working, only to give me the "delayed" error. And my machine no longer recognized the external hard drive.
Me too. I'm using an OWC 500gb FW800 drive. Won't recognize it. I have a couple of Mini G-Drives that are 400 and 800 which I can connect only using the 400 to 800 converter cable. 800 to 800 does not work.
I am having the same problem. My Macbook Pro is not recognizing my external Lacie HD, which connects via USB, or my Time Machine, which is wireless. My time machine still works as a router. I think this is a software issue that cropped up with one of the last updates. Any suggestions??
I am having this same problem. I have a USB external drive and a Firewire 800 drive that I was backing up to using Time Machine and suddenly Time Machine just froze up. Then when I restarted the machine just gave me a grey screen and wouldn't boot until I disconnected the drives.
Now the drives won't show up in the finder. I can see them attached using system profiler but I can't access them. This is really frustrating.
I'm going to add my experience to this thread: Been using a 500GB Seagate portable external harddrive with my MacBook Pro for about 6 months to back up my MacBook as well as my iMac Desktop. Have had close to a dozen backups successfully performed on each machine. Yesterday, my Seagate went to back up the MacBook, and time machine displayed a message that it could not read the previous backup and needed either to erase it or create a new one (something like that anyway). It backed everything up from scratch -- took about 25-30 mins. After that backup was completed, I took the drive to the imac and attempted to do a backup and the imac was unable to see the drive. I launched Disk Utility on the imac and it was able to see the drive, so I tried to verify the disk. Midway through, DU said "this disk needs to be repaired." So, I began the repair process. After about 10 mins, DU said this disk cannot be repaired. I brought the disk back to the MacBook and same result-- MacBook could not see the disk even though it had just back up the entire thing 30 minutes previously. Figuring the drive was busted, I went out and bought a 1 TB seagate drive. Upon connecting it to the MacBook, it launched an internal app which installed Memeo (apparently Seagates version of Time Machine). Once done, I launched Time Machine and it reformatted the entire drive. Then it backed up the entire disk-- again taking about 30+ minutes to do so. I walked over to the imac and presto-- exactly the same thing happened as before-- it could not recognize the drive. Again I launched DU and it said the disk needed repair, and again the repair process stopped after a few minutes saying it could not repair the disk. Bringing the EHD back to my MacBook, I plugged it in and nada. The macbook will not recognize the drive. It can see it within the Disk Utility program and from within system profiler, but it appears not to see it on the desktop.
Now that I have two apparently non functioning backup drives, I would greatly appreciate any insights you guys could offer. Thanks.
I've been scouring forums trying to find a solution to this problem:
I am trying to restore files to my girlfriend's MacBook from her external hard drive. She had previously backed up files so I know that her WD2500ME is compatible with her machine. This external hard drive does not use a separate power source, but draws only from the USB cable. The drive is fine. I've plugged it into my PC and have been able to view her files. The file system is FAT32 which should be fine with her mac. When plugged into her machine, the HD lights and spins up. It does not show on her desktop, in the Finder, or under Disk Utility. As far as her MacBook knows, nothing is connected. I have reset PRAM, but didn't change anything. I've encountered one more curious variable. I have two USB cables that I've tried connecting the HD with. The first allows the drive to light and spin up on both of our machines, but neither will recognize it. The second cable allows full functionality with my PC but when plugged into her MacBook the HD only lights (and blinks) but does not spin up. I'm thinking we're looking at some sort of cable issue here, but I'm baffled as to why these two cables are behaving in such different ways. Any new suggestions would be greatly appreciated.
I am having the SAME problem
Why is Apple not doing anything about this? I have a lovely LaCie, and I simply cannot get Timescape to recognize it. If someone calls Apple Care, can they please post the solution? (my applecare has expired)
