Is there a way to check my hard disk for bad sectors? I dropped my MacBook off a 2nd floor balcony onto grass and I don't want to get a nasty surprise sometime in the future when it tries to write to a bad sector.
Please don't say fsck because there's nothing wrong with the file system because I dropped it when it was off.
MBP 2012 running on OSX10.9.3 crashes frequently. Disk Verification gives an error during "Checking extended attributes file." and asks for reboot and repair. No error could be detected and no repair would be done when DU is run during restart.

I just put in a 320gb 7.2K HD to replace my MacBook's 120GB. I'm wondering how to check the load and unload cycles of the new hard drive?
Also, I've got all my stuff on my 120GB drive while the new 320 is in my MacBook with a fresh install of Snow Leopard. I've got a hard drive dock that connects via USB. Can I somehow get all my files off of the 120gb drive without switching the drives out?
im running 10.6.2 and was wondering if and how is it possible to remove bad pending sectors.

I'm just wondering if this solves the performance degradation issue of SSD's over time. Has anyone tried it and benchmarked the results before/after?
In theory it seems like it would work (albeit at the penalty of losing all data on the SSD).
I use Paragon NTFS to access a firewire/USB2 1TB drive. I recently noticed that some files on it, videos', won't copy to another drive. Using ViSTA and Firewire(Boot Camped) the Vista OS says the disk is unreadable, but the Mac OSX(10.5) just hangs after so many seconds. I've identified 9 large video files I really want back, what do you guys suggest for file recovery? I have Vista Ultimate 64bit and OSX 10.5

does fsck or fsck_hfs scan a hard drive for physical errors also or is it only for the file system layer?
View 2 Replies View RelatedI want to upgrade one of the two 500GB HDD I currently have in my MBP 5,3 with a 1TB one. Given that I had good experience with WD, I am looking at their offerings. While their standard WD10TEVT is hardly available around here and if it's much more expensive (for what ever reason), I am interested in the WD10TPVT. Now that HDD has the new Advanced Formatting with 4k sectors which seems to be only a problem for WinXP. But could any Mac user share its experience with that HDD? Is it gonna work the same with Time Machine, backups, file transfer between disks or can issues occur when files are exchanged/transferred between disks with different sector sizes? Only want to upgrade one of my HDDs for now, so is there any preferable setup (in terms of which HDD to have the OS and which the files)?
View 1 Replies View RelatedI upgraded my MBP internal hard drive to a Samsung 1TB and it crashed for the 2nd time (will never buy another Samsung). So this time, I purchased a WD and migrated my system to the new drive sucessfully. I just wanted to see if anyone knew if the migrate function simply copies files or if it copys sectors of the hard drive. Basically I just want to know if Mac Migrate will copy the crap from the Samsung drive that might cause my new WD to act up - or if that's possible?

I am considering purchasing diskwarrior but want to make sure it can help my situation before I purchase it. My imac will not boot from the internal hard drive (Intel processor) When I use disk utility to try and repair the disk, I get error messages and it won't repair. I can see the HD but cannot repair it. When I connect using target mode with my mac book pro, the hard drive does not appear on my host (macbook pro) computer. I have reloaded OS X (Leopard) onto a firewire external drive and can boot my imac that way but I can not find my original internal Macintosh HD. Will disk warrior be able to help with this scenario. I would really like to access that internal Macintosh HD and retrieve my files.
View 3 Replies View RelatedI have a 2TB Western Digital My Book Studio FW800 external that has 5 partitions, connected to my 2011 iMac. I had help doing the partitions and don't really remember the reasoning, but one is just for my SuperDuper! backup, one is Miscellaneous, one for movie clips off my camcorder, one for misc scanned photo's and one for my genealogy research. I back up using Time Machine to a Time Capsule and also to this WD hard drive with SuperDuper!
Recently I'm getting a pop up message that "Mac OS X can't repair the disk "Genealogy"'. And it needs to be reformatted. It's become a read only disk. When I look in Disk Utility it shows all the partitions as "Mac OS Extended (Journaled)" EXCEPT for the one in question. I also noticed that there are a lot of files with "date created" being the same date in 1969! These files may be letters I've written or photo's I added to that partition within the last few years.
I think I have to completely reformat the entire external hard drive to repair this, but I want to make sure. Because it's going to be a major hassle backing it all up to another external (having to get one first) and then figuring out how to make the files that have turned "read only" in that one partition, back to their original state! Does this sound right, that I have to reformat the entire external hard drive? And how do I get the read-only files back to their original state.

Recently I purchased an external hard disk, to put all of my pictures of my baby due to space limitations on my internal laptop drive. Since my Canon camera 10 megapixel pictures take up a ton of space this was occurring at an alarming rate. My intention was also to back up to DVD but never got to it. This is both a comment and a question.
Now said baby, is getting really good at pulling cords etc. He managed to do this on the external drive firewire cable. As far as i know the drive was not in the process of actually writing. However, after a few minutes and trying to re-plug the drive the OS crashed with a Grey Screen of Death hardware error that tells you that you need to push the power button..
This apparently corrupted the drive's directory. Upon reboot the drive would not mount. Since there were time machine backups on the drive too Diskwarrior was not able to reconstruct the drive in the built in memory available on the computer. Time machine stores millions of files and Diskwarrior apparently wants to keep it all in memory at once. Since my computer has 2GB you would hope that would be enough but apparently not. So that failed. Other utilities seemed to be able to find the files but not restore the directory. I also took it to the apple store they were not able to recover it.
I have to say this is extremely distressing, and hard to believe that a simple accident like this could cost the loss of thousands of pictures. I did send it to a rescue company but that was expensive but I think apple needs to do something about this situation.
On Windows there is a way to disable the write cache for external drives. This is not available for Mac OS X. This would prevent this rather common occurrence of a plug accidentally becoming disengaged when the drive is not in the process of writing. This reduces the odds but I still think apple, in order to become clearly superior, needs a better solution.
I know Apple has experimented with ZFS would this not eliminate this possibility of this kind of disaster? Is this in Snow Leopard desktop? I know they are thinking this is a business customer focused technology but clearly if it can eliminate this kind of thing then I think it is extremely useful to their non server customers. Perhaps there are other ways of dealing with this issue but ZFS is designed to deal with these issues. HFS+ is extremely fragile to disk corruption.
I know my situation is not that uncommon and this is not the first time this has happened to me with an external drive. You would think I had learned. I hate to think of how many other people have had the same thing happen to them.

I have a Seagate 1 TB Backup Plus Drive which was working perfectly fine until I plugged it into a USB hub. It detected it while in the hub and I was able to get files off of it, but when I ejected it from the hub and put it back into the USB slot on the computer it was not detected by finder. It shows up in the disk utility and I clicked verify and repair and it says:
Verify and Repair volume “Seagate Backup Plus Drive”
Checking file system
Volume repair complete.
Updating boot support partitions for the volume as required.
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
Is there any way to get this to work properly again? Or if not is there a way for me to recover my files on the external hard drive?

Next year when snow leopard will be released I was thinking to upgrade my poor 60gb hard disk to something more probably to a 320 one, but I got one problem I lost my recovery disk and actually I don't really need it as you know Tiger is very stable.
When my old macbook will have inside the new hard disk do I need to reinstall tiger then upgrade it to snow leopard or I can directly install snow leopard?
I have an external 500GB Freecom USB HDD with two Data partitions on it (FAT32 and NTFS). With a Windows tool, I made the two partitions smaller in order to free up some space (ca. 200GB) for an additional Mac OS Extended (Journaled) partition. This partition I wanted to create with the Mac OSX 10.6.4 Disk Utility. When I pluged in my USB HDD in my new iMac it mounted the two partitions, NTFS and EXT32 and the Disk Utility tool also showed the free (unpartitioned, almost 200GB) space on the HDD. Then, I chose to create a new Mac OS Extended (Journaled) partition and let the tool do it. ...which I probably shouldn't have done. Disk utility stopped and showed an error message saying that it cannot read the partitions anymore and that it needs to be closed. No partitions can be mounted anymore since then on this HDD. Here is the logfile entry of Disk Utility (unfortunately, it's in German):............

whenever I run Time Machine on my PowerBook G4 (1.5 Ghz / 1Gb RAM / OSX 10.5.8) it will eat up GB's of hard disk space while 'preparing the backup'. After that it finishes the backup, but I don't get the space back. I'm talking about the internal HD, not the external target disk of course. Does Time Machine use the space to generate some temporary files? Any ideas how I can get my disk space back
This doesn't have to do with OS X as much as it does my ISP (Comcast 15Mbps/3Mbps Down/Up). Comcast states you get speeds "Up to" those advertised which basically means you will never get those speeds but once in a blue moon it could happen.
I've been watching my Router activity for a few minutes (see Top graph of the attached image) and I never get near either of those advertised speeds as expected. I am downloading Xcode DMG from Apple and a few torrents are running with no bandwidth restrictions.
My question is currently I'm getting about 50% of my advertised bandwidth, if I reduced down to the 1.5 Mbps Comcast package would I probably still only get 50% of that bandwidth? I think I already know the answer but was curious what you guys thought.

A bunch of the Files and Folders have a Date Created of Dec 31, 1903 8:00PM.
The Date Modified is correct.
It's not every file/folder either. Mostly contained in one directory I have with client files in it.
I have:
- Reset PRAM
- Reset SMC
- Verified Permissions, Disks
- Deleted Finder's plist
So far, still happening.
Anyone have a clue as to what to check next?
I'm trying to figure out when this happened.....only noticed it today.
Could it have anything to do with sharing files from an XP machine.
