  1. Well did you have a backup? Fuck you! no ! lol
  2. I know this video is a bit older but I just had my first run in with data loss a few months ago. My MacBook Pro Retina had a bad SSD that I didn't know about because it hadn't lost anything. After upgrading to Yosemite and deciding it was stable, I wiped my only Time Machine volume because it was nearing full.

    A few days later, I moved an .MOV file into a folder on my Desktop and everything looked fine. Closed the file and went about my work. I reopened the file to grab a PDF and everything was GONE. The video I had just moved and existing files, gone. Ok fine, I had already started backing up to Time Machine and had about a weeks worth of backups on my drive. I went to restore the data and Time Machine mysteriously lost the directory to every documents and sub folder!

    I called AppleCare about ready to blow my f-ing top when they said to take it to the store. I backed up all my data onto another hard drive which I backed up to a volume on my Mac Pro which was then backed up onto the Mac Pro's Time Machine disk. Sure enough it was the SSD that had failed, so Apple replaced it and I got the machine back with a fresh copy of 10.10. I moved my data back manually and pledged to never delete my Time Machine volume again. Luckily, all the important data (priceless family photos I just moved to the computer) that was in that folder was still siting on the original media so I just have to move it back.
  3. A few weeks ago, I inserted an SD card into my pc before booting, which screwed it up, so just today I reinstalled ubuntu studio. Luckily I didn't lose important files!
  4. Did you have a back up? "NO! FUCK YOU! Why do you think I'm so pissed off?!" I laughed my ass off at that one. Classic!! Because you KNOW that's what you want to say to the guy who just asked you that question. Don't care who you are -- that's the FIRST thought that runs through your head. :-) Great vid.
  5. @dxproductions100 Corsair.
  6. @dxproductions100 The Raid Array's brand is "SohoRAID"
  7. @dxproductions100 Yes, but it was 1 month old.
  8. JUST USE CARBONITE WITH A TWIT PROMOCODE
  9. To prevent any more horror stories like my Garageband lost data, I did buy one FF-class 1To external drive. After checking it out with Time Machine, I eventually formatted the 500 GB to clone the whole freakin' system. So that's how I found my way to redundancy.
  10. @brutusunix Raid 0 is data striping with no redundancy and 2x failure rate possibility. Size is based on the smaller size of the two (or more) drives. Two 500 GB drives in a Raid 0 config will yield 1 TB of 'scary storage; - larger volume, no redundancy. Raid 1 is mirrored - what is written to drive 1 is also written to drive 2. A pair of 500 GB drives in a Raid 1 config yields 1 volume of 500 GB, with redundancy.
  11. About horror stories I've recently lost all my Garageband files except their AAC copy in ITunes. I don't know how it happened neither how can I bloody retrieve them ? I opened Time Machine to go back in time but it just failed. They're all lost. Well, there hadn't that many but it's at least annoying. All I can do about it is to start new projects.
  12. I don't trust seagate at all, the 250gb drive in my laptop died without warning after just a year and a half and the 500gb drive in my desktop PC has a small resistor hanging off the bottom of the circuit board! God knows how that thing still works... I'm gonna be buying another drive to backup my data redundantly from now on
  13. dd bs=512 if=/dev/rdisk# of=/some_path/to/new/image.dmg conv=noerror,sync This command will create a block level clone of a hard drive and skip any sector errors it encounters, and puke it out in the form of a DMG file. This will work if your drive will mount, but is inaccessible (physical failure) I used it on a bad drive once, but unfortunately the drive's motor was starting to die and i could only get 700MB out of 40GB =(
  14. My SSD died!
  15. I've been using computers for at least 7 years now, and i never had a hard drive failure. But, in my laptop i upgraded the hard drive, from 120GB to 500GB and when i tried to use the 120GB in another laptop, it said 54GB, it was partitioned correctly, tried everything. Still 54GB. But no real hard drive failures/loss of important data. :)
  16. *agreed I've also found the toshiba Latop drives to be pretty good :)
  17. @Mikej2156 Seagate HDD's (new) are horrible... WD HDD's ftw.
  18. I brought a 500gig Seashite ATA drive for my DVR, installed it and recorded loads of programs, movies and music vids. All was well and good for 2 weeks, I had masses of space (Since the DVR came with an 80gig), but i went to watch a movie one day on my box and it froze, then reset. After that it wouldnt detect the drive and the drive it's self was making those horrible sounds. I loast weeks worth of programs in 5 seconds flat :/. I never could recover any data dispite me trying.
  19. you have quite a collection of HD, im doing a research on computer forensics for my college, mostly i use opensource tools and work on Linux but the ones you mentioned cut my eye i'll give em a try too see whats better
  20. Why wouldn't you use testdisk/photorec ?
