ESATA HDD Random Disconnect SOLVED!!!

Fellow ThinkPad owners:
I've spent the greater part of the past two days trying to resolve the issue of my eSATA connected ThinkPad 500GB SHDD's tendency to randomly disconnect itself. I had just gotten my new W520 with Windows 7 64bit preinstalled, and was happily working away (I'm a banking applications developer) when out of the blue I would get a ThinkVantage message asking me to recover my current files to the C:\ drive. To my surprise and dismay, I noticed that this was occurring immediately after my HDD had "dropped" off MyComputer's list of available drives! I spent all day on the phone with Lenovo tech support to no avail. I did notice, however, that opening the ThinkVantage ToolBox (PC Doctor application) was a surefire way to cause the HDD to "drop" off immediately.
SOLUTION:
Uninstall ThinkVantage Toolbox!
The problem has now ceased, and I've also noticed that the fan in the W520 is not nearly as overactive as it had been while the ToolBox was running in the background.
Come on Lenovo, don't saddle us with additional bloat that actually impedes proper function of the **bleep** hardware!
And to PC Doctor, I suggest heeding the Hippocratic Oath: "FIRST, DO NO HARM"!!!!

Thanks for posting your fix...
I agree, ThinkVantage Toolbox has gotten pretty invasive as of late. It has also become less useful, although you can install custom add-on modules to make it better. Anyway, it is possible to keep the program installed w/o having all the background tasks. This leaves the Blue ThinkVantage button active.
Install TVT
Launch TVT, Settings, then untick "Enable Quick Hardware Check", Save
right click on task bar and uncheck TVT
run taskmgr.exe
Disable PCDEventLauncher, PCDoctorBackgroundMonitorTask, and SystemToolsDailyTest
PCDEventLauncher will most likely be recreated if/when you next run TVT- but it is of little conequence.
Also, are you are using AHCI? It is required for eSATA hot plug (+ some other features). We have had systems that refuse to keep a eSATA drive connected when running in compatible mode.

External HDD randomly dismounting

I have a WD HDD in a Macally enclosure. There have been no problems with the setup until recently, when the HDD randomly dismounts. I've read other posts that say it might be happening during a TM back up along with an error saying it was removed incorrectly. I haven't had any of those errors, nor anything funky in the TM widget log.

I'm trying Repair Disk right now. We'll see how that turns out. In the interim, any other suggestions?

Hi swobo04
I don't see how Time Machine would be causing your problem, the
+"Event store UUIDs don't match for volume: Macintosh HD+
+Node requires deep traversal:/ reason:must scan subdirs|new event db"+
message would be more the product of your improperly ejecting/dismounting drive.
Most likely you have a faulty connection with the cable, a problem with the enclosure or a failing hard drive that you need to solve.
Disk Utility may help if the HD's file structure is damaged or corrupt, but probably will not detect an intermittent hardware problem with the enclosure or drive.

The Wi-Fi randomly disconnects, and now it is not even available as an option in the "Network Preferences" area.

After having the MacBook Pro for about 1.5 years, the Wi-Fi randomly disconnected. Ethernet works fine, however, whenever I tried clicking "Turn Wi-Fi On", nothing happens. I have tried a SMC reset, resetting the PRAM (resetting the PRAM worked for a bit and then suddenly it didn't), and shutting down/restarting the laptop multiple times. Often times does the Wi-Fi turn back on, however it immediately disconnects after about a minute. Now I have come to a point where, in the Network Preferences area, the Wi-Fi option is not available on the list that is on the left side of the preferences. A PRAM reset solved this case, but for some reason it doesn't work anymore. I took it into a local Mac store, where they said that they would need to check if it was the Wi-Fi card that was causing the problem and would need to charge me $50 for the tech service to check it out (which is obviously what I would not do...at least if there is some way to go around this). Help.

I am also suspicious that your WiFi card may have a probelm.
Do an SMC Reset before you do anything else.

Mac Pro randomly disconnecting USB devices

Hello All,
Am hoping someone out there will be able to advise me. I have a 1TB external SATA drive connected directly to one of my Mac Pro USB ports, (that is, not via a USB hub). The Mac Pro has a habit of randomly disconnecting the drive during file transfers. It seems to particularly do it when the screen saver initiates itself. I've disabled the screen saver but unfortunately that hasn't resolved the problem. The problem itself doesn't seem to be isolated to the external USB hard drive either. The Mac has on occasions disconnected other USB devices too.
Any suggestions or ideas on what the cause of it is and how I resolve it?
Many thanks
GPJ007

Yes Grant, I've exchanged the power suppply, cables, the HUB and also the HDD and checked them on my MBP - they work fine. The only USB slot that's working fine is the one on the PCI-E Card. All internal Ports do eject the USB HDD's and also have problem with Printercommunication. I can mount the USB HDD without Problem, until I want to access a larger File or transfer data from or to it, then it ejects itself - well after freezing the Computer for 5min first, until the unmount message appear.
By the way: Sorry, was a bit frustrated. I'm working as an Freelance Editor and really need to have a working USB. But the only thing I found were a huge amount of questions to the same problem, but no solution. And from apple side the only advice was to not use third party device or use only powered HDD's and HUB's. That's not really helpful...
GPJ007: Ok, I hoped to not have to make a new Setup of the OS and all the program. Well in a few weeks there is a gap in the order chain, I'm going to reinstall the OS then and let you know about sucess or not.
Thanks in advance

Sporadic random disconnects this week, very bad to...

I've never had any problems with BT Home 2.0 until this week, I have moved nothing about in my room nor adjusted any settings on the hub and my PC. I have changed the filter and still the same problems occur. I've noticed a lot CRC /HEC errors on the up stream... I live in Bristol if that might help to solve the problem. Maybe something next door could be affecting the line or a BT engineer has messed around with something on the exchange? (I am using a wired connection BTW). Any help and suggestions appreciated, thanks, Rob.

Sorry I can't offer any magic suggestions.   I had been getting regular disconnects for some months and even though I was keeping the router continuoulsy powered to avoid loss of line synchronisation it still was occurring.   See my comments in the thread "Re: Disconnects on Accessing HH and Random Disconnects at Night" for 10 Feb.
The Forum Moderators were very helpful and responded to my queries and arranged four visits from OpenReach to try and sort out the problem.    Eventually they decided that there was a fault in the exchange boards and made some change. Subsequently I kept the router powered up until the 13 May to make sure there was no synchronisation interrupts.   The line eventually stabilised at 14,336 kbps.   It has remained at that even with my logical disconnects at night from the HH Home Page.
I found from a search back in Jan as reported in the thread "Re: HH Type B Energy Consumption & Switching Off the Router" , that the Type A software version was 8.1.H.J. I don't know if it has been upgraded since.   I have found for my Type B that when received it back in Oct 2010 the ver was 4.7.5.1.83.3.5. and it is now ....83.3.18.   - when it was changed/upgraded I don't know.
As I say, although I still get random disconnects, it doesn't seem to affect my line rate.   Not sure if it is noise on the line (i have made a quiet line check and that is OK) as the Noise Margin is ca 7.6-9.1dB. I get disconnects sometimes when I try to look at the ADSL Settings, etc., having typed in the password for access. I have just looked at my Events Log and there have been a number of disconnects today since the router was logically connected at 14:04 this afternoon; 5 in total I think!   And the rate is still shown as 14,336 kbps.

Having said that your rate is quite reasonable and unless you are playing games or watching videos perhaps the interrupts will not be serious.   We only use it for email, family history, ebay and browsing so it is not really noticeable.

Please help! iMac randomly disconnects from internet. Wi-fi via BT hub. I am baffled by all of the suggestions when I google this problem! Any simple solution? Thanks!

Please Help! My brand new imac randomly disconnects from the internet. We have a BT hub - wi-fi. I have googled this issue and see that it is relatively common and it is incredibly frustrating. sadly, I have been unable to wade through the suggestions others have had as to how to solve the problem as i have no technical knowledge and am basically baffled by the list of suggestions. Please can anyone explain why this happens and what to do? It is fairly simple to reconnect each time but it is driving me mad having to. It generally happens when the computer is asleep but sometimes in the middle of doing something. Thanks!!!!!!

What frequency, security are you running? It would have been helpful if you specified in the first post.
Did you create a new Location in System Preferences->Network pane, Location pull-down. Create a new custom named Location. Then after you create that new Location click on the 'Apply' button to save that new custom named Location. See if that helps.
Lastly a lot of people have reported that WEP in lion is problmatic and it would be better to use WPA2 if you can.

My phone will randomly disconnect from the wifi and when I retype the password it says it is wrong. It will eventually work but I have to wait for a message to pop up on my screen to allow me to retype the wifi password.

When I first got my phone it worked perfectly fine with the wifi. Although later on I began to have problems connecting it. It will randomly disconnect from the wifi and when I try to retype the password it tells me it is wrong, although it is right. It will eventually work but in its own time, a message will pop up and allow me to type in the password and it will work. But sometimes it takes an hour or more and sometime it takes 10 minutes. I've seen where other people have had this problem but I don't know how to fix it. I'm not sure if it's an issue with my phone or if it's with my wifi. Does anyone know how to fix this?

Does this happen with all Wi-Fi hotspots? A specific one?
Have you tried forgetting the Wi-Fi connection and then reconnecting to it?
What about power cycling the Wi-Fi router?

This is all the information from when I fist see an wireless interface.
All, I can tell is that my wlp5s0u1 doesn't go down, but a few seconds before I plug in my wireless bridge, or enp4s0, my 'Internet stops...' Or I can't search google, and my youtube stops streaming, conky says that about 30bytes get transfered from that point on, and there is no errors?!
I'm not on a laptop, and my device's power saver is set to off. And as I'm not getting the second error I don't know how to fix this.
$ iw dev wlp5s0u1 get power_save
Power save: off
(Sorry if this is blatantly obvious, I've only had arch for under a month, with no prior Linux experience, and my dad can't help me with it too!)
EDIT:
Please can someone please tell me something that I can try or look into to resolve this, I have a useless dongle now, and an Internet connection that drops at least 50% of the packets.

Random Disconnection From My Wireless Access Point

I got my MacBook a few weeks ago, wand I'm loving it... for the most part.
Info: I've been using my Linksys WRT54G router for years. I've never had a problem. I currently have a desktop Mac connected to it along with my MacBook, and the connection on the Mac is fine.
*The problem:* My MacBook doesn't hold a steady connection to my router, even when I'm just mere feet away.
*What happens:* I have a very strong connection on my WiFi with the built-in AirPort. Then, a few seconds later, all of the 4 bars drop to 0 for a few seconds, jump back to 4, go back down to 0... you get the picture. I find this frustrating, as the internet may shut down for a minute at a time, regain connection for a few seconds, and then lose connection after about 10 seconds. I am unable to use iChat (it shuts down whenever I lose connection), or easily browse the internet.
*I know it's not the router. My desktop Mac connects with ease. Should I take my MacBook to a Genius Bar?*

IPod Classic Randomly Disconnects from Car Stereo

I have a 160GB iPod Classic that is hooked up to my car stereo. Previously it was connected to a 2012 Kia Sorento SX and it would just randomly disconnect from the stereo and freeze. The only way to get it back was to do a hard reset (menu/select button held down), then start playing a song, and then connecting to the stereo. It didn't happen frequently, but maybe once or twice a month. Annoying. But I thought it had to do with the way Kia implemented the connection to the iPpd.
I just recently acquired a 2014 Acura MDX and I've already had that same annoying problem twice in 2 days. So now I'm starting to think maybe it's the iPod.
In the past, I've done a full restore, repaired the drive, etc. Nothing seemed to help.
Any ideas? Thanks!!

Sometimes this works. Otherwise you will have to wait for an updte to the car system or the iOS on the iPod
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset the car system
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.

Network drives randomly disconnecting, unable to reconnect

I have been having an issue with network drives randomly disconnecting. When I try and reconnect using the Connect to Server dialog, the share is greyed out. My current workaround has been to open up terminal and run umount /Volume/Share_Name, and I am able to connect again afterwards. This is happening multiple times a day, and across multiple servers. I have poked around the forums and seen some people with similar issues, but the solution of connecting with cifs:// instead of smb:// has not made any difference.

which ultimately means apple didn't do enough testing before releasing the last patch
This is not always, and may not be, the case. What many don't realise is that many 3rd party developers stray from the 802.11 series specifications in an attampt to boost speed and get one up on their competitors. For instance D-Link, amongst others, use a short preamble setting by default in some of their routers to improve performance. However, this is non-standard and when it comes across wireless network adapters that don't support this then you have problems. They assume that their network adapters are being used for "maximum speed and compatibility". Whether Apple should or should not support a short preamble is another subject altogether.
However, I do agree with you in that Apple should put more work into their Airport software.

HP Pavilion dv5-1108ax, Windows Vista 32-bit: BIOS Boot Order does not see external eSATA HDD

I am trying to run some Linux OS (Debian, Ubuntu, Fedora) from my external USB 2.0/eSATA HDD on my laptop. I can boot from a USB connection but not from an eSATA connection. Is there any chance of updating the BIOS to support booting from eSATA? Is there something I am missing in the BIOS setup menu?

No the eSata port is not bootable.

Hi, I have a HP Elitebook 8740w from which I have removed the internal HDD and connected an eSATA HDD which is powered from the USB bus (I've done this for security purposes). I'm having a problem whereby when booting at initial power-on, a Non-System disk or disk error is encountered after the HP screen. I can then boot into Windows by pressing CTRL+ALT+DEL however having to do this each time I start up is not ideal. Also this error is not seen when rebooting, only at power on. I have tried powering the HDD from the supplied AC power pack and the problem disappears which make me think it is an issue with the USB power (either insufficient current supplied or full power is not available at start up). I have tried all combinations of USB2.0 and SuperSpeed USB ports with the supplied USB Y cable without success in removing this error. Any ideas? I would prefer to run the HDD from the USB ports to save carrying the AC power pack and because often only one power point is available. Thanks

I think I've worked it out... I was running the laptop on mains power only with battery removed. Tried it with the battery installed and problem disappears, it must provide extra power at startup to spin up the HD. Laptop AC adaptor is 200W though, would have thought this would be enough...

Wifi randomly disconnects from my macbook pro running 10.9.2.

Wifi randomly disconnects from my macbook pro running 10.9.2. Rebooting is necessary to regain the wifi connection. The wifi power indicator indicates a full connection, but the card sees no wifi networks. I have renamed the location, deleted and reinstalled the wifi interface, moved the wifi inerface to the top, and reset the DNS. This problem is continual and occurs with all wifi spots. Please help.

It seems that the wifi on the computer shuts off and will not turn on until the computer has been rebooted. Can someone poease help?

CUCM Random disconnect errors

I have a client who is getting random disconnect errors from his cucm servers. They seem to encompass other network errors at times as well, but not always. I'm having a hard time telling if its cucm or if it is a network issue in general.
I pulled his core logs and at the time of disconnect messages from RTMT I'm seeing this:

and lots of them, for a few minutes and then it stops. When I search around for solutions for this I see "contact TAC" repeatedly. Can anyone help me determine if I have a cm problem or a network problem. He did reboot the cluster 12 days ago and it didn't stop the problems. The disconnect errors related to all components of the phone system (cucm, cuc, uccx, cups) and have been anything from "SDL link to remote application is out of service", "OUT-OF-SERVICE AppID : Cisco UP Presence Engine ClusterID", "
The Cisco UP Presence Engine service on the peer node of a subcluster has failed AppID : Cisco Syslog Agent ClusterID", "user 2 ntpRunningStatus.sh: Primary node NTP server, SVUCCX01, is currently inaccessible or down"
So its just like all communication breaks and then comes back again. I'd like to do as much leanring as possilble with this and not just run to TAC. Any suggestions?

Hi Dustin,
Please see the explaination for the error you are getting:-
CCM_CALLMANAGER-CALLMANAGER-1-SDLLinkOOS : SDL link to remote application is out of service Remote Application IP Address [String] Unique Link ID [String] Local Node ID [UInt] Local Application ID [Enum]Remote Node ID [UInt] Remote Application ID [Enum]
Explanation   This alarm indicates that the local Unified CM has lost communication with the remote Unified CM. This alarm usually indicates that a node has gone out of service (whether intentionally for maintenance or to install a new load for example; or unintentionally due to a service failure or connectivity failure).
Recommended Action   In the Cisco Unified Reporting tool, run a CM Cluster Overview report and check to see if all servers can communicate with the Publisher. Also check for any alarms that might have indicated a CallManager failure and take appropriate action for the indicated failure. If the node was taken out of service intentionally, bring the node back into service.
Reason Code - Enum Definitions

CallManager
The most common Lost communication for CallManagers could be Callmanager server hang, network problems or high CPU
You can use RTMT to monitor this.
CM servers keep a TCP connection to other servers in the cluster. When that TCP connection is broken due to network connectivity or lack of server resources, the above error is generated.
Also the sdi traces you have provided won't be useful to analyze the problem but rather please take detailed sdl traces.
If possible then take SDL detailed traces with sniffer filtering TCP port 8002 in order to find out if this is a Network problem or not.
Sometimes due to highly fragmented disk can cause heavy disk I/O utilizing all the CPU.
Was there any upgradation or migration activity was carried out in network?
Please check the server NIC and switch NIC or other NIC have the same speed/duplex settings.
