Ok first off I want to say I've searched and searched and searched to no avail in trying to find a solution to this I've come to the conclusion it's software and not hardware based. Let me start from the top.
I've had an older computer (HP Pavilion a408x) out of commission for a while due to a 'sploded psu. I finally get around to ordering one, install it and everything is good. I bring it back to my office and hook it up to the internet and as expected there's updates. So I up date it and after the updates are installed the computer restarts automatically (weird yes) and as it's coming back on it detects errors and runs CHKDSK. So I let it run and it gets to part 2 of 3. At this point in time my partner is really needing to print sometime and all computers print through this computer. So after about 45 minutes CHKDSK is still on part 2 at only 15%. So I'm like "screw it" and manually shut down and restart. It's at this point I get a "primary master hard disk failure" at the boot screen. Letting start up continue I get a "Stop : c000021 unknown hard error \systemroot \system 32 \ntdll.dll" At this point I realize something is delectably wrong.
Found this thread
, which didn't help much. At some point the c000021 error stops and I start getting "disk boot failure insert system disk and press enter" and I found this thread
, which didn't help much either. I have also been searching other sites as well.
Here's what I found out that's important.
- HDD shows up in BIOS
- HDD shows up at the boot screen.
- Recovery console does not find the HDD
- Repair does not work becuase HDD is not detected
- HDD does not show up in other computers (shows failure at boot screen)
- Removed CMOS battery and replaced, didn't help
- FDISK did not detect the HDD
- Drive is currently in the freezer
- Changed jumper to Cable Select no help
- Tried unsuccessfully to create a boot disk.*
This drive is only 20gb, I'm trying to retrieve files that are valuable to me. If I can get these and the drive dies I'd be happen. 20gb drives are laughable these days. Any help would be GREATLY appreciated. This is the first problem I haven't been able to solve with information that's already been posted. Thanks in advance!
