Conventional hard drives are magnetic media, so why is it if you disassemble one and stick a magnet to a platter, you don't feel any magnetic attraction at all? I can understand feeling a very weak level of attraction, but it feels like sticking a magnet to a piece of plastic or wood.
My Mom has an old iMac that's always seemed a bit sluggish. I recently installed El Capitan and it's now painfully slow, so I tried the noatime trick and it makes a big difference. Problem is I can enable it using the terminal but I can't get it to persist across reboots. Does this have something to do with Apple's System Integrity Protection?
My girlfriend has a herniated disk in her neck, for which disk replacement seems to be the best option. Her medical insurance isn't cooperating, and so we're starting to look into private options and medical tourism. Any advice on going down that route, particularly the medical tourism route, since it seems important to find a good surgeon (and we're not quite sure how to do that abroad).
What I really want is an 8TB hard drive with an ethernet port on the back side. The Intel NUC is almost right but it only supports a 2.5" drive at best. Is there a product that does what I want? It must run Linux but doesn't need to be particularly fast.
and that worked just great...only it did something to the other partition which has caused it not to mount, to refer to itself as disk3s5. It refuses to mount and if I click "verify disk" it says the disk needs to be repaired and to click repair disk. When I do so I get "disk utility can't repair the disk". So what on Earth did disk utility do to the other partition which I did not ask it to touch? The original job was completed because the file system of the other partition was NTFS and it's now MacOS Extended. Any ideas?
I want to clone the boot disk of my OpenBSD install, with the destination drive being larger than the source. What's the easiest way to do this? Just use dd and resize partitions after? rsync? Something else? [more inside]
What is the best open-source method for imaging an entire external hard drive, and then mounting the resulting image as a read-only drive under Windows? The drive in question is an external USB FAT32 hard drive with two partitions. Is there a robust Win32

I have a windows laptop with only 128G SSD hard drive, which is not partitioned, only with one partition C: . I want to install Linux aside from the original windows 7 so I can have double OS. There are about 15G empty space I gues it's enough. I think I need at least two partitions in order to do this. So I went to Computer Manage storage trying to shrink the C:, however, it shows 0 shrinkable space. Why is this? Should I run Disk Defragment? Anyone can help me out? And it's appreciated if you can give me some detailed step by step instructions, ie, how to mount partitions. I'm a newbie to linux and what I'm trying to install is elementary OS Luna. if you can share with me some introductory articles on the basics of the system adminiatraion, OS install stuff it will be greatly appreciated. Thank you very much!
Based on your answers to my prior question, I keep sensitive files on my Mac in an encrypted disk image. I back up my Mac to Time Machine, plus a local external Superduper! clone, and to Crashplan. How do I ensure those backups accurately record the disk image--do I have to eject the disk image or will the backups copy the open (mounted) disk? [more inside]
According to Disk Utility, I have only 36 GB / 500 GB free, and it's been pretty full for a while. For the last year I've taken this at face value, but today I looked into it closer, and found that according to other applications (Disk Inventory X and JDiskReport), I apparently should have more like 200 GB free. How can I figure out what is using this extra space? [more inside]
So I've been at least preliminarily diagnosed with a herniated disk at the L5-S1 level. This is after a couple months of back and leg pain and an attempt to treat it with oral Prednisone. The Prednisone worked for a few days while I was on it but the pain came back after the course was over. Yesterday, I went back to my GP and he gave me the diagnosis and referred me to a neurologist and is arranging for an MRI. My question is: have you been through this, what was your treatment and how did it go? [more inside]
I need a 3.5 inch disk drive to read some old documents on my Mac.

When a friend's grandfather died, the family found a drawer full of mysterious brass disks. The grandfather had a lot of random scrap metal and other odd items around the house and grounds.

Let's say I want to buy a new external hard drive. I can pick a case with a particular interface (USB2/USB3/FW400/FW800/eSATA) and a mechanism with certain performance characteristics (RPM, latency, transfer rate, etc).

I've got some cardboard tubes from plastic sheeting - in all different lengths and widths. I want to be able to put shelving on them - so I'll be needing a round disk that'll fit in about 1/2 an inch snugly and have a screw protruding so I can then bolt the wood to the screw and tube. What is this disk called and where can I get them online?
I have an old windows 2000 box. I recently used Acronis to clone the primary master drive. I have done this a number of times before with other boxes and even with this box. When i swapped the disks and tried to reboot, BIOS detects the disk ok, but then i get a Primary master disk failure message. So i put back the old drive and I get the same messge! I would be surprised if Acronis did something to both old and new disks during the cloning process. I can access the disk contents fine on other boxes using USB setup. So can the IDE cable have gone bad suddenly. Is it possible the bios detects the disks but cannot find boot information because of faulty IDE cable ?? [more inside]

I plan to return to playing World of Warcraft. However, I need to keep the game on an external hard disk, or at least temporarily transfer it from the computer's drive to that disk frequently. When I played before, the files (install files or the installed game) would not copy to the external drive, although I have never had any such problems with a non-WoW file. I am thinking of getting an install CD for the game, so that instead of transferring from the computer to the external drive, I can just erase and reinstall. Problem is, I would need to reinstall all patches each time I did that. Does anyone have any ideas about why the external disk doesn't like WoW or how I can get around this?

My Maxtor Basics 1 terabyte external USB 2.0 drive no longer mounts. I have been through all the usual stuff with tech support (including disk management and device management) and I've tried it on multiple computers. Although the green light comes on when it's plugged into USB, apart from that it's not talking to the computer. There has been no strange noise, clicking, smoke or smell. Maxtor tech support say it's a failed drive. A data recovery company I phoned said it's probably damaged firmware but the data on the disk is probably safe. I'm nervous about sending it to a data recovery company because I seem to be looking at about GBP £179 minimum or maybe many, many hundreds more. Is it likely to be a matter of simply soldering something here or replacing something there, ie a job that I could take to a local geek? Or should I be looking to take this to a major data recovery centre? I'm in London, UK.
I just pulled an older computer out of the closet to donate, and yesterday it booted up fine. Today, I get an error stating "A disk read error occured, press CTL ALT DEL to reboot." I used UBCD for Windows and I cannot see the hard drive when I boot from there either. What other avenues should I explore to try and fix the disk, or is it toast and the files unrecoverable? I am willing to open it up. Thanks in advance. [more inside]
