Since upgrading to Mavericks, almost every time my Mac awakens from sleep mode, it says my Lacie drive was not ejected properly. I have to unplug it each time & reconnect it, plus I have to close down I-Photo & reload it.
Has anyone had a similar problem and if so how did you solve this?
Many thanks
Stephen
iMac, OS X Mavericks (10.9.1), Lacie 2GB hard drive
Same problem here. iMac and Sierra. LaCie 12TB 2big Thunderbolt 2. Also brand new. Volume disconnects itself without any apparent reason and I get a message saying I shouldn't have disconnected it without ejecting first.
But also, I am having major difficulties writing to it. It isn't possible to copy whole folders over to it. The LaCie baulks both at folder and individual files, usually claiming an error -50 but sometimes other 2 digit error numbers. Other times it says there is an error in a particular file such as the format of its title
I think this is a MacBook Pro related problem. It happens to me with two different LaCie drives (1TB and 2TB) and with a new powered G-Technology 4TB drive bought at an Apple store. It seems I just can't connect any external USB-C hard drive. 😠
Is your Seagate (ie Lacie, Seagate drives inside Lacie) drive a thunderbolt or USB?
does it ever unmount in any situation OTHER than sleep mode?
If thunderbolt, this is known in some instances to occur and *is being looked into.
until resolution, dont sleep your thunderbolt ext. HD.
I use a Thunderbold cable and it only happens when I wake the computer from sleep. I have tried unplugging the thunderbolt cable and I have tried unplugging the power cable but it still repeats the problem. I never had an issue with this before I upgraded to Mavericks but now it happens all of the time.
When you say don't sleep your Thunderbolt, how can I do this?
Hi PlotinusVeritas
I too have this problem with the LaCie 2Big 8TB drive arrays, of which I have two. They are connected via thunderbolt to a Mac Pro running Mavericks.
I opened a case with Apple and they called me to advise that the problem was that the drives were not spinning up fast enough.
LaCie, on the other hand, say that "despite thousands of sleep/wake cycles" they were unable to reproduce the problem - though it is clearly illustrated in the logs and they do not dispute that it occurs.
So when you say "it is being looked into" can you advise by whom and for how long?
I would appreciate some information - I have asked LaCie for a return authorisation and am awaiting their response.

You have to do this in settings - turn off the "allow disks to sleep where possible".
I Have same issue but with LaCie D2 Quadra connected via FireWire 800 so this isn't just a Thunderbolt issue
I should add that I am running Yosemite on an iMac
Is anyone having trouble with the Lacie 2Big 6TB thunderbolt drive disconnecting? It is a TB2 drive and I have it connected directly to my MBP via thunderbolt. I had not expected this type of trouble with such an expensive drive. Even my WD TB drive stays connected! oh yes, I am running ElCapitan OS
I had this issue in 2014 - see my earlier post. I spent a lot of time troubleshooting this issue with LaCie in Sydney and then with LaCie Head Office and with Apple.
I have to say that the support from LaCie was absolutely woeful. The emphasis was on denial that the problem existed, despite many similar problems on various chat sites.
I never got LaCie to admit that this was their problem - even after taking the drives to an Apple Store and reproducing the problem on one of their Macs.
I returned them as "not fit for purpose" to the distributor.
I purchased the Pegasus2 R4 drive array and installed 6TB drives and have had no problem since.
A couple of useful points:
The problem usually occurred if the drives or the Mac went to sleep. But there were also random disconnects at other times. Once one drive disconnected, all disconnected. Apple were adamant that this was a LaCie issue. The lack of problems since installing the Pegasus array seems to confirm that. Also the post below suggests that the LaCie issue is in the driver.
LaCie Head Office told me (eventually) that they were unable to reproduce the problem over hundreds of sleep cycles. However it turned out that they had no thunderbolt 2 devices to test this with (I have a Mac Pro) so were using older Macs with TB1.
I am not surprised that the problem still occurs. It is not MAC OS related - I was running OSX 10.8 originally and upgraded to 10.9 during this time but it made no difference.
The problem does not occur when the drives are connected via USB3 (but this is a much slower connection).

In this post the users are having exactly the same issue with Drobo drives. The solution, in this case, was a firmware update from Drobo.
Which settings are you going to? Couldn't find in System preferences and tried searching in finder. FYI I'm running Sierra and having same issue with Lacie 2big 6TB thunderbolt 2.
Same problem. MacPro and Sierra. Disk (Lacie 2big 6TB thunderbolt 2) brand new.Shutting disk off/on won´t work. Must restart Mac Pro.
Pretty strange, but mine started to behave after a complete time machine backup. Weird ?!! Some of the issues you describe call for a backup and erase...
Erase of the LaCie disk you mean? If so, using the Empty Trash function in the Finder or using a proprietary app like Cocktail?
Lacie drive keeps disconnecting
