I have an hp pd1000a. my computer will detect it but when i try to view my files, the hdd disconnects. It connects and disconnects randomly. the hd spins and the light goes on. sometimes it will disconnect, and my computer will say it has incorrect perameters. can someone help?

First of all, was your HDD connected internally or externally. And Did you ever used any folder lock software on the HDD or Bit locker. If not, then Find a software package called File Scavenger and install its full version on your computer. Run it and make sure it can recognize your locked HDD, then select Long Recovery. Your files will be recovered slowly until the progress goes to 100%. Then Click on TREE VIEW to be able to view the contents of your HDD the way they were., Then select recover and select a recovery destination. Probably not to the same locked HDD

Thank you, I hope my post will help you somehow

Hi,
HDD not Detecting only Some region, if you HDD data cable damage, HDD power Cable damage, HDD port damage, or HDD bad sector. But normally you change HDD data or power cable or mother board port. And i suggest mother board all connection disconnect and only HDD connect and open bios and search your HDD detected.

First reset the CMOS. Check your motherboard specs for how to do this or remove the small round silver battery from the motherboard; wait 30 seconds and reinstall it. (It is a good idea to replace with a new battery.) This will reset the CMOS. Then reboot to see if HDD is detected. If not, go into the BIOS setup (repeatedly hit F10 at HP logo screen) and check to see if your hard drive is listed. You may have to set it to "on". If it is listed in BIOS, but not detected another drive (a bad one) could prevent it from being detected. If you have any removable or external drives attached to your computer, disconnect them. Reboot your computer to see if your HDD is detected. If not, open your case and disconnect the data cable from all drives except your primary hard drive. This includes the floppy, optical, zip, backup, or secondary hard drive(s). If your HDD is detected, reconnect each drives data cable one at a time rebooting between each. If after reconnecting a drive and rebooting, your HDD is not detected the last drive is a bad drive and preventing your HDD detection. I have found that sometimes a bad drive that is connected will let the HDD be detected then on later boots the HDD will not be detected. Also it is possible that your BIOS is corrupted. Let's hope not. Another possibility is a bad motherboard. I hope this helps you.

Is this an external 1TB Hard Drive? Maybe it's to big for your computer. If it's an external drive try it on another computer and see if it works. There is also the possibility that the external 1TB drive is bad.

If it's not an external hard drive then try the steps below.

Click Start/My Computer and see if your hard drive is listed as a device. If not, turn the computer off, remove the battery, remove the cover that houses the hard drive on the bottom of the laptop then remove the hard drive from the bay. Wait 30 seconds and put the hard drive back into the bay and reboot. Now see if the hard drive is shown under My Computer. If not, the drive might be bad.

Shut down the computer.Disconnect the ide cable from hdd .Just connect using primary hdd and boot the computer. Shut down the computer. Connect the secondary hdd both IDE and power cable.

If still not detected try connecting secondard hdd on different computer and check.

hi ,

looks like u primary hard drive is inside the laptop and so should be displayed as c : drive ,

and the reason , the external hard drive is not displayed seperately is csue ., the external HD  may be added as slave to the internal HD .,

can u tell me ,make a right click on c:/ drive and choose properties : and tell the totalsize dispalyed 

if it cant detect ur HDD ... then check for jumper settings. ...

try to fixed HDD inside the system some wiring maybe lessen.

If not solve, change the cable connecting the HDD.

if not solve; Try boot the system with windows installation disk.

if still see the problems.

HDD maybe damage

If the the disk is detected;
You should back up your files and install new windows if it is necessary.
