Operation system not found

I ran across your blog you wrote to something I was looking up and you said:
Your hard drive is most likely bad or the ribbon cable is not connected.

My computer gets a black screen that says Operation system not found and then I also notice media test failure; check cables. You mention about ribbon cable is that the same thing. Do you have any suggestion. I tried booting the cd OS and change the bios to boot to cd first and it doesn't work. I'm thinking it's the hard drive or MBR is shot.

Operation systems not found

One of two things could have happened, either something got severely corrupted in windows and it doesn't see the boot portion of it anymore, or the hard drive may be experiencing a hardware failure. You can check the hardware with a few tools that are out there (I like SeaTools, myself, or SpinRite), to see if the hard drive is failing (or even recognized by the system). If it is, then unfortunately, your data on the drive stands a good chance of being lost for good. You can always try using an external USB enclosure to see if the drive will mount on another computer (or this one of you get the hard drive replaced), and try to retrieve your data that way. If not, then see if there is some kind of data recovery service in your area that you can take the drive to, but be forewarned that they can get quite expensive.

As for another option, if the hard drive is okay, again, the same deal applies to your data, but once you're able to retrieve data (if you're able to), you can try using Acer's built in recovery (by pressing Alt-F10 at the Acer splash screen) to restore your system back to factory specifications. If not, then you might have ot use a set of recovery disks, ones that either came with the system when you purchased it, or ones that you would have had to create using Acer's eRecovery Management software. Just remember that restoring the computer using either of these options, will erase any remaining data off of the hard drive, so be sure that you have data backups if you were able to do so, before you go through the restore process. If you don't have disks and the built-in recovery doesn't work, then you may need to either use a vanilla copy of Windows for your system (check the bottom of the computer and look for a product key so you can tell which version of Windows you have), or contact Acer to order a set of product recovery disks specifically for your model of computer.

Hope this helps you out!

Hard Drive Read Failure

No--I would say that the hard drive has gone bad on you.
The BIOS can see a hard drive, but it can't tell if it's any good.
If it's defective, well--you see what happens!

Hi,? my machine has an error of loding operating system it's hp 530,it brings this informationn (no hard drive were found ,so it is not detectiting any hard dirve installed.

The most likely explanation is that your hard drive has failed. You can try removing and reseating it. Failing that, borrow one for testing or buy a new one. As a last resort, try putting the hard drive ( or even the whole laptop ) in the refrigerator overnight. Really! :) If this restores operation even temporarily you definitely have a bad hard drive.

My IBM Think Pad T30 showin working on AC with out powering..

If it's not finding the operating system, and you'va ran the recovery cd, then the problem is going to be that the hard drive has failed and will need replaced. In order to double check and make sure it's the hard drive, run the recovery or operating system disc, and reformat the hard drive. If the hard drive will not format, then it's bad.
