Will files be damaged when I accidentally disconnect an external Thunderbolt HD? With early Firewire this could fatally corrupt a HD.

Back in the day I had a few instances where a Firewire 400 cable was disconnected by accident. Even though no files were transferred at the time (exept perhaps as part of invisible background operations) this corrupted files, entire folders or even made the drive itself unreadable.
With Thunderbolt, do I have to fear similar disasters? I use two external Thunderbolt drives because I'm down to a single Macbook Pro and need the external space.
Or are there new protocols in place that prevent such calamity with Thunderbolt? (An aside: Thunderbolt doesn't even show up in the tagging categories (unlike bluetooth or Firewire). It's been around years and despite superior specs has few products and little market penetration.)

NOTE: for anyone who may come across this thread and has had the same problem, Apple fixed the problem today with their release of OS 10.8.2, so Apple was at fault after all.
But if you are interested in the Seagate Thunderbolt 3TB drive, I would highly recommend it to anyone, as it is awesomely fast and after almost four months of use, seems to be very reliable so far.

Will Exception be thrown when Socket is disconnected?

Hi
I would like to know will Exception be guaranteedly thrown if the other side(client or server) disconnect.
If not, how do I test the other side socket has been gone?
Thanks a lot
Matt

When the remote end of a TCP/IP connection calls close() on its socket, the remote operating system sends a FIN packet to your operating system. After this, if you try to read or write to the socket, you get an end-of-file indication. The indication depends on the API you use; it can be an IOException, -1, null, etc; read the API doc for the method you use for reading and writing.
A somewhat related question is: what if the peer computer crashes, or its Ethernet connector is unplugged. Then it can't send you a FIN or anything else. When you write to the peer, your operating system will send the data, and wait for a reply (ACK packet) for a while. The ACK doesn't arrive, so your OS will re-send, wait, re-send, and finally give up, after a minute or so. After that you'll get IOExceptions when you read or write to the socket.
If the remote end crashes or is unplugged, and you read() from a socket, nothing happens. Your read() will patiently wait forever for data that will never arrive. For this reason, it is sometimes advisable to have a "heartbeat" in your protocol: send some dummy "are you there" message occasionally. That will trigger the send/wait-for-ACK/re-send/wait-for-ACK process, and after a minute your read()s and write()s will IOExcept to tell you the other end is gone.

How can i start the Admin server? may be this will be like clue: "When i try to start the iplanet suite with the start-admin script, i receive the following error:

so i can not login to console (./startconsole) because the "admin-serv" is not up: "Can not connect to the Admin Server "http://myserver.com:myportnumber/" The URL is not correct or the server is not running." any ideas..."
---------------------Seumas Froemke on 1/15/2002 said: ----------------
"I'm not familiar with the error, but I'll throw in my two cents and hope it leads you somewhere.
First, be sure you start things in the correct order. LDAP->Admin->Console.
Be sure you've set nsadminservaccessaddresses and nsadminaccesshosts.
Do you have problems starting everything up when you aren't using SSL mode?
You can put startconsole into debug mode with startconsole -D 9 but I don't think there is a start-admin debug mode. You'd have to settle for a truss.
All in all, you should ask this in the LDAP (User Management & Policy) forum."

The FIle Size increase when I transfered to another external...why?

I just bought a new external hard drive to replace my old external. After copying all my folders and what not to the new hard drive, i noticed that some of the file sizes weren't the same as before. Yet everything looks like it copied correctly.
Example:
Video folder on old HD = 5.6 GB
Video folder on new HD = 10 GB
Is there a logical reason for this and should I be concerned?

I believe that your issue is because the block (cluster) size on the disks is vastly different. Blocks are essentially the smallest amount of disk space that can be allocated to hold a file and a file takes up a least one block. If the file is bigger than the block size by even a single byte, it spills over and occupies a second block, even if it doesn't use the full second block. Thus, you get wasted space when the file size isn't exactly the same as a multiple of the block size.
For a FAT32 formatted disc, your default block/cluster size is either 16KB or 32KB, but for Mac OS Extended, it's 4KB. So, you're going to waste quite a bit more space on the FAT32 drive because its default cluster size is quite a bit larger than the equivalent on Mac OS Extended.

How do I move my default final cut file location from the hard disk to an external thunderbolt drive?

I have FCPX and just bought a MUCH faster TB external drive and don't want to work off the internal hard drive anymore due to speed and space. When I first open FC it shows my external (Lacie) drive but then goes away and only shows the internal Mac drive. I cannot figure out why it would find the Final Cut Projects and Events files on the external hard drive and then make them go away. Please help if you know the answer. Thanks.

I've experienced that behavior if the external drive has a file named something like AVCHD, DCIM, movies or similar at the root level of the drive.

Hi, I have a mac mini..all of a sudden when I wake it up in the morning it says I didn't disconnect y external properly and it will try to retrieve the information..it finally appearsbut it never used to say I should disconnect the external before...help

Hello, my mac mini has suddenly started displaying a warning sign when I wake it up..saying I didn't properly "eject" a device... It is referring to my external/backup hd {on which I store music files, photos, back up files, etc}. It has never happened until yesterday... and I have had the hd hooked up for over a year. Each night I just put my mini to sleep and when it wakes in the morning everything is fine... the only time I ever disconnect the external hd is when I completely shut down or unplug...the procedure then has been to turn off the mini...then disconnect the external hd and unplug it. This has always worked fine, then suddenly it says I haven't properly disconnected the external hd... I don't know what to do... am I supposed to use the eject button now before I shut down...and how can I do that... it will state that it is not able to be ejected because it is in use {the rotating photos in my monitor background are stored on the external hd}. I am puzzled... don't want to lose the info on my external hd...but I need to be able to put my mini to sleep. Help, please.

Have the pics allways been used off the external drive?
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
Is Spotlight indexing that drive, or is it used by Time Machine?

Oops, I disconnected an external drive and now I can't backup.

I am backing up to an external firewire disk. I accidentally disconnected the external drive. I re-connected it and only two of my three partitions are visible now. I ran disk utility and repaired the disk with no errors. When I go to the finder only two of the three partitions can be seen.
When I backed up with time machine it said that it needs 13.97 GB but only 4.43 GB are available. I cleaned up the external drive but I get the same error. I went to /Volumes/Time Machine (my backup partition) and the files I had deleted were no longer there.
Any body have an idea of what is going on here?

Hi, and welcome to the forums.
How did you do that? Did you delete TM backup files via the Finder? That's likely to be a large problem. Unfortunately Apple doesn't do a very good job of warning folks not to do that, other than using special "deny everybody everything" permissions. Do a +*Repair Disk+* (not permissions) on it again. That may not gain any space, but if DU can repair them successfully, you may be able to continue using them.
If Disk Utility sees it, but the Finder doesn't, it may just be that you need to reset your Finder preferences. From a Finder window's menubar, select Preferences then either General or Sidebar as appropriate, un-check the box for +External Disks,+ then check it again.
If you get the TM drive repaired, and still have the problem, post back. Include the size of the data on your internal HD, the capacity of your TM drive, and whether there's anything else on it besides TM backups. Also Click here to download the +Time Machine Buddy+ widget. It shows the messages from your logs for one TM backup run at a time, in a small window. Copy and post them here.

WRT610N disconnects and does not work with Vista or media center extenders like the DMA2200

Linksys and all other router manufacturers advertise the greatness of the wireless 5ghz band (especially with 802.11n), but I’m beginning to have my doubts. It is true that the 5Ghz band is hardly being used so you'll have virtually no one to compete with. However, the 5Ghz distance in no way compares to 2.4Ghz, and as a matter of fact, I find it to be quite terrible. At approximately 20 feet away, both my Linksys DMA2200 and HP notebook barely get 1 bar using the 5Ghz N band with my WRT610N router. In comparison, while using my 2.4Ghz WRT54g router, I get 5 full bars at that range, and at least 2 bars from anywhere else in my house.
I have all Linksys equipment in my house as I have been impressed with all of their 2.4Ghz in the past. However, I’ve recently upgraded everything to dual-band N equipment and found numerous flaws in each of the new devices, plus none of them really even play well together. My setup is: Linksys 610n router, DMA2200 media center extender, and a WUSB600N Dual-Band Wireless-N USB Network Adapter for my laptop – all of which are currently using the most up-to-date firmware. Other devices include a WRE54G extender and Nintendo Wii.
Problem #1) The LELA software with the new N devices doesn't even recognize that my DMA2200 is a media center extender. Using LELA, I should be able to select my media extender and allocate more bandwidth for streaming media. However, since my extender only shows up as an “unknown network device” those options are greyed out. I tried to manually change the device to a media center, but still no go. I suppose you can manually allocate bandwidth in the router setup somewhere, but considering these are all Linksys products, it’s absolutely ridiculous that an option specifically incorporated in the LELA software for a Linksys Media Extender does not work!!!
Problem #2) If you are only using one system with the router, the router might actually work as intended. For most of us though there are going to be at least 2 or more systems connected to the router (wired, wireless, or a combination of the two) such as a PS3, Wii, laptop, PC, media extender, Xbox, etc. If that’s the case, you’re probably screwed because you WILL experience frequent dropouts… ESPECIALLY if just one those clients is a VISTA machine. Check the Linksys forums and you will find that this seems to be a problem with all of the new Linksys routers (610N, 310N, and 110).
Here is a Microsoft article that explains the issue
http://support.microsoft.com/kb/928233/en-us
Problem #3) Because of problem #2 I will never be able to get rid of the dropouts since my network is using one of Linksys’s media center extenders. The DMA2200 is essentially a VISTA PC to some extent and accepts DHCP requests the same as a VISTA PC. Since it is not really a PC though, there is no registry modification that can be done to alleviate the VISTA problem (not that the registry mod really works anyways). So as long as I try to use my DMA2200 wirelessly with my WRT610N router, the frequent dropouts will occur and there’s nothing I can do about it. This is REALLY TERRIBLE since the DMA2200 is specifically designed to be used with the WRT610N router in order to take advantage of the 5Ghz band and wireless N transfer rates. You absolutely need 5Ghz wireless N to efficiently stream HDTV WIRELESSLY, but if you lose your connection every 10 minutes, it is impossible to watch any type of streaming media.
Problem #4) As mentioned already, when the “N” 5Ghz range is working on the WRT510N router, the distance sucks compared to standard 2.4Ghz G, N or mixed mode networks. You can try to make it better by strictly using N products, disabling the 2.4ghz band all-to-gether, and using the wider 40mhz frequency, but it doesn’t really help. The higher 5Ghz band is a more concentrated signal and therefore simply does not reach as far as the lower 2.4ghz band. I wonder why all of these new products state that the 5Ghz range will increase your distance, when in fact it actually makes it worse?
So… basically, this router does nothing that it claims too and is basically rendered useless on any network with a VISTA machine. This has not been addressed by any Linksys firmware updates or VISTA software updates so there is no reason to even consider using this router if you you’re using VISTA or some type of VISTA Media Center Extender such as the Linksys DMA2200.
Although, I’ve always sworn by Linksys in the past, the amount of wasted time, frustration, and horrible support has really changed my view about them. I’ve reverted back to my old trustworthy WRT54g router and had to run cable through my house so that I wouldn’t have to box my DMA2200 extender up and let it collect dust in the attic. It’s really disappointing that I spent all this money to buy this equipment specifically because they’re supposed to work together, but in fact they don’t. Plus what’s the point of having top notch wireless equipment if you have to run cables in order for them to work?

I have fixed all the IP adresses to avoid the DHCP problem but I still have problems.
I have sereval scenarioes:
1. MC < 1Gb wire > WRT610N < 5.0n WIFI > MX
I can see HDTV on this one but it disconnects
2. MC < 1Gb wire > WRT610N < 2.4b/g WIFI > MX
No HDTV and disconnections
3. MC < 2.4b/g WIFI > WRT610N < 2.4b/g WIFI > MX
No HDTV but no disconnections - but very slow and streaming like youtube
4. MC < 100Mb wire > WRT610N < 2.4b/g WIFI > MX
No HDTV but nice picture - testing for disconnections right now - 30+ min.
Result:
This test was very good. Stabil streaming, no disconnects for an hour. Won't support HDTV but the rest seem to work fine.
5. MC < 100Mb wire > WRT610N < 5.0n WIFI > MX
Not tested yet - looking forward to this - might bring me HDTV.
Result:
This gives HDTV but there is a problem with stability on the streaming but very difficult to see on the picture. Testing for disconnects - now tested for 30 min. - no disconnects.
This looks really promissing.
I am pretty sure that the WRT610N have a problem in the switching part of the router specially when it has to switch from 1G to WIFI. I bought the WRT610N to get HDTV on WIFI and Cisco markets the DMA and WRT610N as a perfect match. But it definately have problems - i still do not understand their silence about this.
I will come back with the last results when I have them
