Can scrambled video be related to bad sectors on hard drive?

I bought my iMac refurbed from Apple, and it had to have both its logic board and power supply replaced four months later. That was a year ago, and in December it started exhibiting problems that I thought were related to the logic board: scrambled video at startup (a kind of multi-colored plaid on the screen, or strange distorted blocks on the display); kernel panics; slowdowns, crashes, and freezes in all applications, including the Finder; and refusal to shutdown. Since this iMac is out of warranty, and I did not purchase AppleCare on it, I had resigned myself to buying a new Intel iMac when the G5 finally died. This although it passed the Apple Hardware Test.
Today my AppleCare kit arrived for my Powerbook G4, and just for a lark, I thought I'd run TechToolDeluxe 3.1.1 on the iMac, not expecting it to show anything. To my surprise, it reported 14 bad sectors on the surface scan of the hard drive. (It passed all the other tests.) This would actually be good news, because I could buy a new hard drive for $65 or so from OWC and install it myself.
But my question is, how could bad sectors relate to the video issues I've experienced intermittently? Is it simply possible that both the logic board and the hard drive are failing?
Thanks for any insight or advice,
Nancy

Miriam,
I was afraid that would be the verdict: the strong possibility that both my logic board and my hard drive are failing. Sigh! And unfortunately my rev B iMac (17-inch ALS) is not covered under Apple's Extended Repair program, which is just for 20-inch models. Another sigh. Although it would cost me only $75 to replace the hard drive on this iMac (these non-Intel ones are user-serviceable), I'm not sure that I wouldn't be sending that money down a black hole if it's just a matter of time until my logic board gives up the ghost.
So I'm trying to decide whether to it's time to buy a new iMac now.
Thank you so much for your input. I really appreciate it. And I hope you've dug yourself out of all that snow!

Remapping Bad Sectors on a Drive

Remapping bad sectors - back in the days of SCSI drives - you were able to do what was called a " low level format " which would in effect remap bad sectors on the drive.
I don't see a way to do this with newer software such as disk utility etc.
Example: a friend of mine accidentally tripped the cord to his hard drive in the middle of the drive writing to the disk. Of course this is bad. Remapping the bad sectors would insure that the drive was working properly and not use any potential bad sectors.
Q: How can we remap bad sectors on today's ata and sata drives?
Thanks in advance for your help - RevDave

I don't know if it's anywhere in Apple's documentation, but it's a standard technician practice for that purpose. Here's what Dr Smoke says about it in his X Lab site:
The process of erasing a disk, partition, or volume by writing zeros to every bit on such is called zeroing. Zeroing finds bad sectors and maps them out of service, also known as sparing. When an attempt to write zeros to bad sectors fails, the bad sectors are both marked as occupied in the directory and added to the bad blocks file of the file system. Once the bad sectors have been spared, no attempt will ever be made to read-from or write-to them again.

Would the ir censor go bad if the hard drive cable went bad sens they bout use the same cable?

what happend was that i have an intel ssd 80GB. i was installing a water colling system to my tower so i had to unplug my ssd. ones i had installed my water cooling sytem to my wotwer i pluged in my sdd but it didnt work like if it had died. so i swipet out my macbooks hard drive for the ssd to see if my macbook would reconise the hard drive in the utility but it didnt, and when i put my macbooks hard drive back in. the hard drive dosent get any power. you cant hear it turn on or anything. what i desisded to do is use the enclouser that you use for the optical drive and my mac boots up fine, could my hard drive cable gone bad? if so why does the IR cencor work if they bouth use the same cable and end up in the same conector. i have a macbook pro mid 2009 5,5

2009 MacBook Pros are notorious for having sub-standard SATA cables. I'm 99% certain that's your problem. Even though the IR sensor is on the cable, that doesn't mean that the cable is good - nor does it mean that it's not faulty if it will boot with a hard drive but not with a SSD - SSDs are simply more 'needy' when it comes to a good SATA cable.
Visit www.ifixit.com and find the Apple part number and search for the item on eBay - much cheaper than buying from ifixit; although ifixit will have the instructions for installing the cable.
Good luck,

Bad motherboard - Good Hard drive - data recovery

thinking I should ESATA cable to hard drive and USB -- to look inside hard drive. But I don't know the path to the photos folder. Like to maintain as much info about the pictures as possible - so I can import to new computer Aperature.
WIll that work? (SATA/USB)
WHat would the path be once I can view the hard drive?
Thanks.

You negelected to mention the minor fact of ditching the computer
If you connect the drive as an external drive, depress teh option key and launch iphoto and use the select library command to select your library
As to what to look for - it is the iPhoto library - you can not mess with it it in pieces - it is a database and is a single entity and must be treated as one
For Aperture questions the Aperture forum is a much better place to ask

Bad sound from hard-drive music?

The music stored in iTunes on my mac mini does not reproduce with good fidelity. E.g., If I import a commercial CD to iTunes, using wav, output is substantially inferior to the source CD -- to the point that it's unlistenable on a decent stereo system.

Does it sound like any of these?

You could also try running SMART Utility:
http://www.apple.com/downloads/macosx/system_disk_utilities/smartutility.html
It seems to be a little more critical than Disk Utility, and may detect impending hard drive failure sooner. You can download the demo and run it several times for free.
Good luck!

Bad sectors in hd drive

Hi, All,
my X240 with windows 8.1 recently becomes unstable (error message, pause , and can not shut down properly), so I did a check disk (" chkdsk/f ") on my old X240 today , and it found 96kb bad sector. see the reprot below, I am thinking to replace the current harddrive with a new one , but I wonder if the installation of the operating system would be difficult becuase the laptop comes with no windows OS CD.
regards,
tao

Is it bad for a hard drive to click? because when ever i pick up my mac is mac a click noise near the hard drive and people are saying it is sms or something?

??

SMS means "Sudden Motion Sensor." Its purpose is to immediatly park the hard drive head to protect the drive platters from damage, whenever sudden motion is detected (like the laptop falling quickly toward the ground).
Read this for more info:
http://support.apple.com/kb/HT1935
I don't normally hear the click on mine, though I guess some people say it can be audible. Maybe it depends, like the way some hard drives are louder than others.

Is it bad for the hard drive or the processor to carry my macbook pro while it is asleep?

I know for a fact that old notebooks used IDE hard drives and thus if they are carried while in sleep mode, it might damage the hard drive. For a Macbook Pro, is it dangerous at all to carry it while in sleep mode? Does it affect the processor or the hard drive or any other hardware at all?
Thanks,
j

Welcome to Apple Support Communities
In general, it is dangerous to carry any laptop with a physical hard drive while it is turned on, as the hard drive might get damaged. However, the MacBook Pro with Retina display (the same applies to the new MacBook and all MacBooks Air) uses flash storage, so you can just put the computer to sleep and carry it (you can do it even if it is turned on): no parts will be damaged.

HT4906 My macbook pro is making horrible buzzing and vibrating really bad. is my hard drive crashing?

My macbook pro is vibrating and making a horrible noise.
Is my hard drive about to crash?

Back up quickly.
Better make two backups - one bootable clone.
And I'll ask for your question to be relocated to the MacBook Pro forum.

Wipe out hard drive and clean install

I may have a bad sector on hard drive with Mac pro laptop; OS snow leopard would "hang" & apple logo would appear but laptop would not boot to finder. Genius bar technician instructed me to backup files, clean hard drive to zeros, and reinstall OS software. Could not locate the steps to accomplish this in my manual or apple support site. Could someone point me to the guidance for this?

Launch Disk Utility and read its Help files.

When the Apple Store tests a zeroed out hard drive, is their test as intensive as wd lifesaver etc. software's in napping out bad sectors etc.

When the Apple Store tests a zeroed out hard drive, is their test as intensive as wd lifesaver etc. software's in napping out bad sectors etc.
I do know one test at the Apple store is a three or four hour test that is very thorough for the whole Mac Pro computer, system by system test, I'm curious what kind of test they perform if you're testing the hard drive for bad sectors or whatever I'm a novice
I mean is it as effective or more effective than the software called wd lifesaver?
Does anyone have any idea what software they use or is their test only testing the systems of the computer and not just the hard drive?
I am moving from PC to Mac right now I have not even use my 2009 Mac Pro yet I was told to have the hard drives zeroed out and tested to start with a clean slate this is what I'm trying to do.
Thank you

The chip on the hard drive itself basically takes care of bad sectors. If an operation tries to write to such a sector, the drive will mark it bad and move onto the next one. That's why zeroing the drive effectively does the operation of mapping bad sectors - the whole drive is checked.
Their general hardware test does not do a full drive check, as far as I remember - the memory check can take a long time, though, since they're looking for random errors.
So for your Mac Pro, you should feel confident that doing a one-pass zero (don't do more than one pass, it's a waste of it me), will be enough initialization for the drive. And many drive experts don't even bother with that, relying on modern drive chips/firmware to do the job of checking for bad sectors on the fly.

Utility in Snow Leopard to check sectors of external hard drive

I have valuable data on two external hard drives. Is there a utility in Snow Leopard that can be used to check that all the data on the drives is in good condition (that there are no bad sectors on the drive)? If so, please point me to an article, instructions, etc. on how to use it and if not, does a third party vendor make such a utility and if so who and what is it called?
Thanks for the help. I am grateful.

Running Disk Utility as KT helpfully suggested will run basic repairs.
But to find bad sectors, also called bad blocks, TechToolPro will find them. I rarely use TTP though.... to the point where I think I wasted my money. It helped one time, so I guess that paid off considering what Tech's charge.
The only way to fix bad blocks is to back up to another drive and reformat. Clone it over using the free demo of SuperDuper.
Boot up on your install disk; put disk in and restart while holding down the C key till you get the Install screen.
Don't click on install, go to the Installer menu in the upper lefthand corner of the screen, go to Disk Utilities, choose the drive you want to be free of bad blocks, click on the Erase button, click on Security Options And click the Erase button next to it. Don't choose 7 or 9 way zero........(if it asks for it )....it takes forever and you don't need it !
This will map out any bad blocks on your drive. Then clone your backed up data back to the fresh zeroed out drive.

Question concerning data removal from external hard drive

I have been backing up via Time Machine to a 500 Gig external hard drive. I will be adding a 1 TB external hard drive and switch the Time Machine backups to that unit. I want to then use the 500 Gig unit to store photos, music and video, to free up space on the iMac. I have found the tutorials/threads that explain how to move the photos and music. I have two questions.
First, will moving video from iMovie work basically the same as moving the photos and/or music?
Secondly, what is the proper way to remove the existing Time Machine data from the 500 gig unit, once I have the 1TB unit up and running and know that Time Machine is backing up to it?

I can help with number two. There are two things you can do, one quickly, the second more securely.
Both can be done with Disk Utility in the Apps/Utilities folder. Open DU with the HDD attached to your Mac and highlight the HDD in the left hand pane and choose Erase for the right hand pane. Press the Erase button. It should happen pretty fast, but because it is a big drive it may take a couple of minutes. But this does not really erase the data, and some recovery software could do a good job of getting a lot of you data back.
Since you want to store media libraries on this drive perhaps a better way to condition the drive is to select a Security Option and write zeros to the drive. After this any bad sectors on the drive will be locked out and not used in the future. Because this is a big drive this could take a few hours.

Possible Failing Hard Drive...advice for moving forward

I've been having lengthy delays caused by spinning beach ball of death and decided to get serious about my back-ups while I figured out what was wrong. In addition to Time Machine, have purchased a drive just to have a clone copy of hard drive and a bootable startup drive. While using Carbon Copy Cloner to do this, it reported bad sectors on my drive. Suggested deleting those files which I proceeded to do (deleting those took forever as it initiated the sbbod for each one). But the SBBOD keeps occuring.
I need help and advice to think this through...(actual questions in bold)
5 bad sectors aren't a lot but even 1 that causes the wretched SBBOD is too much. Is there a way to avoid that sector or is it just a precurser of future bad things to come? (let me say here that my drive is not a Seagate).
Do those bad sectors corrupt my clone?
I don't want to weigh this discussion down with too many questions...but these are my thoughts about moving forward
If I decide that, indeed, my hard drive is failing I see the following options:
Replace hard drive (have received local quote of $100 for labor + cost of drive approx $100) - this is certainly the cheapest, easiest and most logical solution.
Take this opportunity to replace the laptop I gave to my daughter when hers was stolen. I would only do this if I could use the iMac's screen as a 2nd monitor. However, the early 2009 iMacs don't support being used as 2nd monitor. I would have to use ScreenRecycler & a VNC. How do those affect performance? If there is no adverse affect, I like this solution.
Any and all advice appreciated. iMac specs in signature.

Thanks for your reply Linc

Rule out other hardware failures such as a damaged SATA cable or a bad logic board.
Do you mean in addition to the hard drive, as that failure seems pretty evident at this point? I guess the cable would be a visual inspection. How would I know about the logic board?
I'm pretty well convinced to replace the Hard Drive. Now the fun question is do I want to go with an SSD drive? I'm reading up now - obviously we're talking expensive for the size I would need. Not sure about these hybrid drives? Small amount of SSD combined with large amount of hard disk? Also reading about using the optical drive slot with something like OWC's Data Doubler. So many options. Any thoughts are welcome
