Possible NIC hardware problem?
Hi,
I have two sun servers, both solaris 9, that act as firewalls.
I have installed only OS Core. The firewall software is Checkpoint.
These two servers are in cluster (checkpoint xl).
I have many other sun servers configured in this way that work perfectly.
But with these two servers I have a lot of network problems.
For instance, if I issue a nestat -rn I see a lot of entries (about one hundred!!). Do you know what this happens?
My security admins think that there could be a nic hardware problem.
How can I be sure that the network cards are ok?
If I run, on both servers, from ok prompt:
test net
I get
rejecting alloc-mem?
What does this mean?
The servers are:
- SUNFIRE V120
- SUNFIRE V240
Can you help me?
Thanks,
Tarek
I would just like to make the point that even though you may have great stability with a number of systems without applying firmware and OS patches, it does not mean that the system you are currently experiencing these issues with will not benefit from firmware upgrade. Some of the systems may have different component revisions that require firmware upgrade. Some of the features that are included in firmware upgrades can improve asr ( automatic system recovery ), hardware diagnosability, hardware integrity and generally improves chances of discovering and isolating faults. So it would be a good idea to implement a plan to upgrade all your systems with the patest firmware.
I would put this system on alert and make a service call with Sun, asr ( automatic system recovery ) can detect early signs that a component is failing and just clearing the disk from asr should not be the only step taken here, the disk may need to be replaced.
I am currently looking through the internal hand book for some references for you, there should be some good spectrum stuff that I can point you to, I'll update shortly.
One more thing, when you were configuring Solaris for FW-1, there are a number fo kernel parameters to change, misconfiguration of any of these parameters could be a cause for FW-1 to report errors.
On the output from netstat -rn, I wouldn't worry about that too much, if the system is a gateway for a large number of hosts it will probably have an enrty for all networks being visted by hosts on the client side.

Looks serious. possible hardware problem. unable to install any OS.
Hi,
Powerbook was working absolutely fine. Stupidly, I attempted to watch a partially (97%) downloaded (with Bittorrent) movie (.wmv -- WM3) in Windows Media Player 9 in full screen mode. Half way through the movie freezes. I try and get out of full screen, nothing changes -- the whole machine is frozen. I restart. During boot there's a serious error -- kernel panic I think -- telling you to restart machine in various languages including Japanese. Restart. Freezes during start up window progress bar. Restart. Freeze.
I start up from the Jaguar disk 1 start up disk, go into Disk Utilties, repair disk -- errors found, and fixed apparently. Restart. Freeze.
I start up from DiskWarrior 4 start up disk and start it on the drive. Step 6: "Overlapped files detected" with a number after, and it starts taking ages. I left DW working for nearly two days until it seemed to have frozen (still on step 6).
I connect the sick PB to an iMac via firewire and start up the PB in disk target mode, the PB's drive appears on the desktop of the iMac and I'm able to easily with no problems copy off all my personal files. At that point I thought all was saved -- I was out of hot water, no further real problems. All I had to do is wipe the drive and reinstall etc.
I reformatted the drive from the iMac choosing to zero aswell. The PB's drive appears on the desktop empty and looking fine.
Start up the PB using Panther retail install disk one click install, it goes through checking the install disk then starts to check the target disk or actually install on the target disk -- at that point kernel panic -- 'restart machine' in various languages including Jap. Start up again using Panther disk, this time choose Disk Utilities to attempt to refromat the drive again, kernel panic before Disk Utilties even gets fully open.
I start up the PB using Jaguar retail install disk one, choose Disk Utilties -- fine. I reformat the drive, this time not bothering with zeroing. Fine. Go through to install Jaguar. Again it checks the install disk fine, then immediately after, kernel panic.
I tried partitioning the drive into two using Disk Utilties on Jaguar start up disk. My thinking was, maybe the start of the drive is damaged. Then tried to install onto partition two: panic. Just to check, tried to install to partition one: panic.
It's a 60GB drive. I installed Jaguar onto it ages ago successfully. The only difference was when doing it ages ago is I used the PB's internal CD/DVD drive. That had since broken and I've been using an external firewire CD/DVD drive -- all the above various Jaguar / Panther attempts were from the external drive. I just received a 2nd hand internal CD/DVD drive I bought on eBay -- I was blindly/stupidly hoping that using an internal CD drive would solve my problem but it hasn't.
What's the problem? It seems as if the initial Windows Movie Player crash has caused this, but that can't be can it? That was a software crash and I've since reformated the drive. There shouldn't be any remnants of that in anyway. So it's a hardware problem? But it was working fine before the crash and nothing has happened to the PB between the crash and now. But there's no two ways about it -- right now the PB seems terminally broken.
Any suggestions how to get my PB working again?
TIA,
John.It's intalled. So it turns out I was lying when I said "The only difference was when doing it ages ago is I used the PB's internal CD/DVD drive." -- I forgot to mention there was no AirPort card in the PB when I installed Jag ages ago.
Also a small note: it seems an internal CD drive was necessary in the end. When the Panther install restarted and requested disk 2 I couldn't get it to recognize disk 2 from the external drive -- had to use the internal one to continue (although I didn't spend too much time/effort trying to get the external one to work but on the face of it it didn't seem to). (Although I can imagine there may be a way of installing stuff from disk 2 after having customized the install to not require anything from disk 2 for the first main automated install possibly? I may sell the internal CD/DVD drive if so as otherwise it was a waste of money).
Having installed Panther I put the AirPort card and the 2nd memory back in and started up -- all's apparently OK, but of course there's good reason not to be convinced of that. I didn't customize the Panther install as I wanted (because I didn't expect it to work). Not sure if I dare try wiping and reinstalling.
Obviously I'd feel happier knowing what the problem was/is. Looks like the AirPort card had something to do with it. But even when that was out the PB couldn't start from OS9. When formatting the drive (from OS X installer software) I'm sure I had the OS9 check box ticked. Even if I hadn't it wouldn't stop the OS9 CD working would it?; the hard drive just wouldn't appear once started up from the OS9 CD.
So I now have Panther up and running with both bits of memory in and the AirPort card in. I haven't messed around with/in Panther at all yet but on the face of it it seems fine.
Any ideas what the problem was/is? Any suggestions how to find out? Should I just ignore it and forget it ever happened (and cross my fingers and hope I never need to mess around with OS installs again)? Would be nice to know what's going on though. For a start it looks like if ever I want to install OS9 on it I won't be able to -- which actually may be something I want to do in the future possibly.
Thanks. -
When updating to Mountain Lion I get this measage
This disk has S.M.A.R.T. errors. This disk has hardware problem that can’t be repaired. Back up as much data as possible and replace the disk.
never had this before download of Mountain Lion.As others have stated, this is a potentially catastrophic event. Consider yourself lucky, as hard drives usually just fail wihtout warning. Your disk could die at any time. This is a mechanical / physical failure, not software related.
Going forward, I would suggest utilizing a utility that monitors SMART status, which you obviously don't have, such as SpeedTools. -
For the second time (I've been to the Genius Bar already once with this) my Wifi isn't working. They gave me a new iphone last time, but the new one has the same issue as the old one, I'm guessing. I've tried resetting the network but that doesn't work.
I see others have this issue too.
If this is a hardware problem why doesn't Apple fix it? Or do I just have to wait another year for another upgrade?
Currently it's not costing me anything - yet - because I've got the Apple Warranty but this is totally frustating!!! I bought the original phone (which has been replaced in July 2012. The new phone (without working Wifi) is a month old.
Will try Restore via ITunes before (I will invariably) have to return to the Genius Bar for another Iphone 4S unless someone has an ingenius solution here?..?sematson wrote:

For what reason, other than making yourself look foolish, would you ask questions that we users could not possibly answer as we're NOT Apple?
Basics from the manual are restart, reset, restore from backup, restore as NEW. Nothing more "ingenius" to suggest than these steps that Apple has outlined in the manual. If these steps don't work, then go back to the Apple store. -
I have a mid-2010 polycarbonate/white MacBook (model A1342) running OS X 10.6.8. My machine has been having issues with the internal Bluetooth and keyboard/trackpad randomly ceasing to function.
Bluetooth issue
As of recently (the past month or two), the Bluetooth adapter will completely disappear and eventually reappear on a random basis. It won't appear at all in System Profiler, and the BT menu says "not available". Also, I have had a few kernel panics recently, all of which were apparently thrown by a Bluetooth process/daemon/driver (unfortunately I forgot which one, and also lost the logs from the panics.)
My system has a Broadcom Bluetooth chip that's part of the AirPort card, but is basically just an internal USB device. The adapter has some sort of integrated USB hub ("BRCM2070 Hub"), which the "Bluetooth Module" device itself is connected to.
Nonetheless, this seems to be some sort of problem on the USB bus. Whenever there is a failure, I will almost always see output in Console showing USB errors (ie errors about "enumerating a USB device", "clearing port power", "setting port power", "getting port status", etc). It will either be on any of the ports of the hub at 0x6600000 (the "BRCM2070 Hub" that "Bluetooth Module" is connected to), or port 6 of the hub at 0x6000000 (BRCM2070's port on the internal bus, which the keyboard/trackpad is also connected to on port 3).
I can post more/longer ones, but here's a somewhat short example of the error messages I might receive:
11/18/12 3:18:36 PM kernel USBF: 7351.492 [0xcf9b300] The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. It will keep retrying. (Port 6 of Hub at 0x6000000)

11/18/12 3:20:20 PM kernel USBF: 7456.188 [0x11fb1300] The IOUSBFamily was not able to enumerate a device.
Keyboard/trackpad issue
There's also an issue where the internal keyboard/trackpad will randomly cease functioning (until I restart), often a couple of times a day as of recently. I've had this issue on rare occasion for a while now, but it's gotten more frequent. And more recently, the caps lock light on the keyboard occasionally turns itself on when I'm away.
Both the internal keyboard/trackpad as well as the Bluetooth "hub"/device are connected to the same USB bus/hub. When the keyboard/trackpad die, I've noticed that there will be very similar messages in Console to those above and usually a Bluetooth failure at the same time. (In some cases, it seems to notice that the keyboard/trackpad isn't responding, then attempts to reset/reinitialize it...ie log below.) What could the root cause be...could it be the USB "root" hub/bus causing one or both of these to fail, or possibly a problematic device causing the other to lose connection? I haven't had issues with USB devices on other buses failing, though (ie no problems with external devices.)
Maybe more out of curiosity than anything else, but I've been poking around for info on what might be going on with the USB (aside from the 0x66 hub repeatedly dropping/reconnecting and etc), but can't find much. There seems to be no documentation about the error codes (ie 0xe00002c7) that the hardware/OS are relaying. I even poked through the source for some of the relevant kexts and some reading on OS X driver/kernel programming too...might as well learn more about the inner workings of OS X
Here's an example of some of the messages that I get about the Keyboard/Trackpad:
11/21/12 2:57:22 AM kernel USBF: 1439.228 IOUSBHIDDriver(AppleUSBMultitouchDriver)[0xd1ff000]: Detected an kIONotResponding error but still connected. Resetting port

Attempted fixes
Unfortunately, my Macbook isn't under warranty so I'm mostly on my own. First I zapped PRAM, reset SMC, ensured OS updates are installed (still on 10.6.8), and threw out a few drivers/software that were possible troublemakers. Next, I tried running another OS/install to rule out software issues. Accordingly, I found that the BT adapter sometimes disappears on Windows 7 as well (just did a clean install). And finally, I bought a new AirPort/BT card and installed it the other day. That seemed better at first, but I still have the problem of intermittent Bluetooth and keyboard/trackpad.
Problems/solutions?
What might the issue be, or is there anything that may be worth trying? As I mentioned, I've reset PRAM and SMC, made sure it's not an OS/driver issue (it happens on Win7 too), and replaced the Airport card. The machine does have aftermarket RAM (from OWC, ~2 years old) and SSD (Crucial M4, installed September)...but it seems unlikely that either of these would cause the problem. There haven't been any accidents that would have caused physical or (to my knowledge) electrical damage to it.
I also searched for any occurrences of similar problems, but could not find any that were applicable to the Macbook revision in question. There was a similar keyboard/trackpad issue on older Macbook Pros that was caused by stress on a ribbon cable...but that seems unlikely given the concurrent issues with Bluetooth as well as the different design.
The only thing I can think of next is to possibly replace the cable connecting the Airport card to the logic board, and possibly look at replacing the keyboard/trackpad (topcase). Anyway, I'm worried that it might be a hardware issue with the internal USB controller/hub, which would probably mean that it's unfixable unless I replace the logic board.
Any advice as to which of these might be a potential solution or cause of the problem? Or might I just as well sell it off in its current condition and replace it?
Thanks all!Has anyone find a fix for this? I've been using my Dragon Dictate headset on my MacBook Pro for about a year, and then today, when I plugged it in, I got this:
4/16/14 10:01:04.000 AM kernel[0]: USBF: 47.766 The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. It will keep retrying. (Port 1 of Hub at 0x4000000)

4/16/14 10:01:07.000 AM kernel[0]: USBF: 50.269 The IOUSBFamily was not able to enumerate a device.
Here is what I have tried so far:
Reset the PRAM
Reset SMC
Verify disk (there were no problems)
Repair permissions
Boot with an external USB hard drive (which works fine on the "problem" computer) that contained an old SuperDuper clone of my hard drive from several months ago. I received the same "The IOUSBFamily was not able to enumerate a device" error when I plug in the headset.
Tried to headset on another computer, and it worked fine.
Plug in an external USB keyboard into the problem computer, and it works fine.
All of this would lead me to conclude that it is a hardware problem. But it seems that if it were a hardware problem, the external USB keyboard and external USB hard drive would not work (which they do). If the problem were with the headset, it wouldn't work on another computer, but it does. So I'm wondering if it's some sort of firmware issue…??????? URG!!!!!! -
"DPC_watchdog_violation" happens almost everyday, tried re-installing, is this a hardware problem?
Hello, I'm from Hong Kong. You guys must be wondering why I'd post in a foreign forum instead of local one - I cant find any support from my local forum. I cant even find this model form my local Website.
First of all, I brought this laptop (Envy 14) in 2013 from my so called "University Notebook Scheme". But once I got my first Envy, problem arised - my screen keeps flashing. I went back to the store and replaced it with a new one. Yet, this "new one" keeps having "DPC_watchdog_violation" almost everyday, no matter what Im doing - browsing the Net, using iTunes, even when Im using Microsoft Office for my assignments.
I've tried many solutions suggested: updating software & drivers, and reinstalling the windows; nothing works. Instead, more problem arised throughout these 2 years: my screen starts to flash, sometimes I cant even turn my computer on (power button on with a black, turned on, screen). I cant update my windows - "Failure configuring Windows updates, Reverting changes" and got stuck in the update loop.
I'm scared to do anything with this laptop now, even typing this "problem discription". I stored every files into the Dropbox for safety purposes. I save my Word documents every minutes, try to run as less programme as I could.
I've been wondering if this is a hardware problem, a serious one. Some of my classmates also got this Laptop from the University Scheme as well, most of them reported with the same issue (especially for the screen/display issue). With the notorious HP's repair and warranty service, I'm discouraged to sent my Laptop to them. I've even heard that I'll be charged even I'm still under warranty.
P.S. sorry if I have made any grammatical mistakes.Additional Information for my Laptop (from WhoCrased):

3g is not working but 2g is fine - could this be a hardware problem?
Just recently updated to IOS6 and now can't get 3g, but I also dropped my phone at the same time.
I've tried all the resets and changed SIM and the issue is definitely with the handset either hardware or software installed on it.
Is it possible that I've dammaged the 3g antenna? I get 2g fine, and wifi fine, so I guess my question is does the iPhone have seperate antennas for 3g?
Thanks
DaveIt very likely could be a hardware problem.
Are you certain that you did not simply disable 3G? Check Settings > General > Network > Enable 3G to ensure it is ON. -
I was trying to install OS X Mountain Lion 10.8... and I got an error saying, "This disk has S.M.A.R.T. errors. This disk has a hardware problem that can't be repaired. I saw several other questions below of people having the same or similar problems. Does this mean that my hard drive is about to crash? I plan to head to the place I purchased and have it checked out. I backed up my data a couple of days ago. Any comments?
Yes, S.M.A.R.T. is a built-in diagnostic on the hard drive, and it is reporting a problem that may cause it to fail.
You can see the same status in Disk Utility, and possibly get more info. Run Disk Utility and select the DRIVE in the sidebar. Be sure to select the DRIVE and not the volume indented below it. At the bottom of the window, there is a field for S.M.A.R.T. Status. If there is no problem, it should say Verified.
You can also do a Get Info on the drive (File -> Get Info) in Disk Utility, and the Info window provides more detailed information (toward the bottom) about what is being checked. -
I have had my Iphone 4 for a couple months now. When I updated it to ios 5.0 I didn't have any problems with it. At first, then after awhile I noticed that it started doing this really weird thing. Sometimes, I could be either using an app, or not doing anything at all and it just be on the home screen, and suddenly the screen would sort of pause and the blinking circle would show up, and maybe last 30 seconds - 1 minute, and then my lock screen asking for my passcode would pop up. I didn't think anything of it, because like I said, it was sort of random and I figure it was just something that happened sometimes, like with computers. Then recently, as in this past weekend, I noticed it was doing it more often (I was out of town and using the phone a lot more than I have in the past) and realized it was doing it more often. I had asked the guy at my AT&T store if he knew what was wrong with it, said he never heard of a phone doing that and to update to 5.0.1 and if it still did to call Apple support. So yeterday, i called Apple support and told him what was going on, he also seemed ot have no idea of this problem, told me to update to 5.0.1 and if it still did it, to call back. So I updated, it seemed to work at first but then it's been doing it again, and even more. Such as its noon as I'm writing this and I swear its done it already six times since I woke up 6-7 hours ago. That's just when I notice it. if it's plugged in, either to the computer or the wall, the way I realize its done that is because it'll beep, like when you connect it. My main question is, has anyone ever heard of, or expereinced this problem? Is it a hardware problem? Software? Update? Something I did? The phone works wll enough for what I need it for, and I'll be happy with that, as long as it keeps working (again, I've only had it two months, so I can't upgrade for a little over a year).
Is it possible that this could be a water damage result, as I may have gotten some water on the phone by accident? (Another eason I'm asking about other issues). There are no signs of corrosion or anything anywhere on the phone. So I'm just curious about any help any one could provide. thanks!Just to update, I took my phone to AT&T (since my nearest Apple store is two hours away and before making a drive wanted to see if they could help). Two different guys looked at the phone and tried different things and both said they thought it was something in the software and it turned out the problem was something in the settings. We reset ALL settings and so far it's gone nearly 36 hours without doing it ONCE (and it was doing it like, every 10-15 minutes). so I hoping that that means its totally fixed the problem. So I'm still not sure exactly what it was, but I'm glad to know that all I had to do was push one button that saved me a two hour drive as well as $149 (if not possibly more).

Troubleshooting Airport-Hardware Problems
Hello - I am wondering if anyone knows of a way to test if the airport card itself is malfunctioning or if there is possibly a different hardware problem.
Several months ago I believe my ethernet port got fried in a lightning storm (because my router, modem and ethernet port in my PC all got fried). I've been solely using my airport card since.
A couple days ago that didn't work either. I am able to connect wirelessly with my new iMac, so it doesn't seem that the problem is with my router. I cannot connect at any of my other wireless spots either.
Before I try to buy a new airport card, I'd like to find out if there's a way to test the hardware.
I have tried reinstalling the OS by doing a Archive and install, but that didn't seem to do any good.
Thanks.Hi, Steve. Does System Profiler "see" your Airport card? If not, the first thing to make sure of is that your Airport card cage is securely connected to your logic board. That connection tends to work loose over time, especially in Tibooks that are picked up and transported frequently.
Go to this page for easy instructions on removing the Airport card from a Tibook. As soon as you get the bottom cover off the machine, the card is right in front of you. First remove it gently from its slot or cage, then reseat it firmly. Finally, press down hard on the rectangular tab at the end of the ribbon cable that's attached to it — that's its connector to the logic board, and that's what most often works loose. If yours is loose at all, you'll feel it click softly into place as you press on it. Then put the bottom cover back on and test again to see whether System Profiler sees the card. Post back with results. -
New Drive has a Hardware Problem?
Hi,
The old hard drive in my iMac finally failed (it was a Seagate with a known issue, but I never got it replaced). Today I put in a brand new drive, exactly same model as the old, but I still get the S.M.A.R.T. error "This Drive has a Hardware Problem that can't be Repaired".
Any clue what could possibly be wrong? I may have misplaced the EMI foam slightly (after some time, the fan spins up), but could that really be the cause? There were no fan problem with the old drive installed.
I follewed this iFixIt guide:
http://www.ifixit.com/Guide/iMac+Intel+27-Inch+EMC+2309+and+2374+Hard+Drive+Repl acement/1634/1
Thanks!
Michael KnudsenI don't understand the SMART report, but unless you got a replacment directly from Apple, it wouldn't have been an exact replacment. That drive, even if it's the same model, has to have a special firmware for the internal temperature sensor and that's only available from Apple. If you've read the OWC blog for the late 2009s that says that you ony need to replace the drive with one from the same manufacturer in order to use the same sensor cable, I believe that's not correct.
The spinning up can be cured by using the free SSD FAN Control. But no idea if that's related to the SMART error. I only know about the temp sensor issue related to this. If this doesn't fix it, maybe you got a bad drive or the problem is located elsewhere, maybe on the SATA controller on the logic board. No idea.

I have used my Treo 650 for years in the US. I've also taken it to other countries (Africa, Europe) and used SIMS purchased there for service while in those locations. Upon returning to the US after each trip, I've always been able to use my US SIM to get my US service back.
However, I went to Thailand in November and used a SMILE SIM and another Thailand SIM, both of which worked in Thailand. Unfortunately, upon returning to the US, my US SIM won't work for getting service any more. (I am using my US SIM in a Nokia phone in the meantime, and it is working. When I put the SIM into my Treo, it will transfer the text messges, but will not connect to my service provider, AT&T.)
I called AT&T and they said it was a hardware problem. I suspect it might be a "lock" problem with one of the Thailand companies. Is it possible that the Thai company locked my cell phone?
So my question is, how can I fix this? Whatever the problem is, I'd sure like my service back! Please help!!
Post relates to: Treo 650 (Unlocked GSM)I don't think a SIM card can lock your phone. Did you let them do anything with the keyboard?
Can you try with a friend's AT&T or T-Mobile SIM card and see whether either will work?
Edit: You can ask about Thai mobile phone company issues on this board: Internet & Technology @ Paknam Web Thailand Forums

Potential keyboard hardware problem T410
Dear all,
since yesterday I have been experiencing a problem with my T410, which is potentially due to
a hardware issue with the keyboard.
A few specific keys are not working anymore. These seem to be the Power On key, the Fn key,
the Alt Gr key, and the ThinkVantage key.
I am assuming it is a keyboard hardware problem, since I cannot use the Power On button to
start the laptop. Fortunately, this is possible using the fingerprint reader start-up.
When the laptop is running (using Windows 7) everything is working fine, except the mentioned
buttons. I cannot access any Fn button functions (e.g. the reading lamp) or Alt Gr symbols (e.g.
the @ symbol which is on my keyboard on the 2 button) or power down with the Power button.
I tried various easy fixes:
* Making sure all drivers are up to date
* Remove and reattach the keyboard
* Static discharge procedure (unplug all power, 10 presses and 30 sec holding of power button)
* Checking Bios settings
* Replace battery
Unfortunately, these did not change the situation.
I am wondering if the simultaneous malfunctioning of these specific buttons points to a certain
hardware problem. I hope a replacement of the keyboard might solve this, but it could be an
issue with the motherboard.
Any hints would be welcome.
Thank you,
MH
Solved!
Go to Solution.Dear all,
thank you for your suggestions. Unfortunately, it was not the keyboard. It appears to
be a more serious problem. In fact, since yesterday the laptop does not boot correctly
anymore. The boot process is started, but I only end up with a black screen, and some
randomly colored first few lines at the top of the display.
It all points to a major malfunction. Unfortunately, the warranty expired 3 months ago...
Regards,

IMac Hard drive hardware problem
I have been having problems with my iMac. Running the disc utility is shows a problem with the hard drive which it can't repair so advises reformatting the drive. Though I can erase the volume I cannot run erase on the disc itself it comes back with the following message.
'This drive has a hardware problem that can't be repaired
Back up as much of the data as possible and replace the disk. See an authorised Apple dealer for more information,
The machine was tuning Lion OS but was shipped with Snow-Leopard, luckily I have a recent time machine backup on my time capsule. So restore should be straightforward, install from snow-leopard OSX disc and then run restore from time machine.
Question is, is it possible to reformat drive, if so how do i do that as disc utility isn't able to access drive or do I need to replace. How easy is it to replace a hard drive on a iMac.
Thanks in advance for any help.
Michael,Disk Utility can only perform 'Erase' on a drive on which it is NOT installed. It can't erase its own drive.
You need to perform the operation from another instance of Disk utility such as booting from the original 10.6 DVD and using its disk utility on the DVD to erase the HD drive in the computer. -
[ Helix ] Rear camera picture malformed, but video is fine. Software or hardware problem?
Hi, it's is my first post here, so welcome everyone
I've just purchased Helix 3702-3LO (i7, 8GB, 128GB, Win8Pro 64bits upgraded to 8.1) and today found some problem. Pictures taken by rear camera are malformed. The picture looks like:
https://drive.google.com/file/d/0B5MpmFU1Jqq8Ym5ucGt6WDhUQXM/edit?usp=sharing
But at the same time video taken by the camera is perfect. So how do you think, is it software or hardware problem?
I've already tried refresh drivers, update what was possible to update, but still no imrovement, I still want avoid sending the computer to the service. It looks like some part of the image (bottom) is paste in the middle. Looks like codecs problem???
But now I'm not sure if it is only software problem or may be some how hardware (video is recorded is fine).
Thank you.

Solved!
Go to Solution.Thank you kroe, you were absolutely right!
I rolled back the driver and it's fixed now, I should think about this in first place! :-)
"Device manager" > "Imaging devices" > "AIT Webcam" > Right Mouse Button Menu > "Properties" > Tab "Driver" > "Roll back driver" > OK
and now I have, like you wrote, "Integrated Rear Camera" instead of "AIT Webcam"
And the photos are perfect now :-) Thx again.
So.. problem SOLVED! Thx
