computer does not recognise hard drive

March 22, 2011 at 06:15:58
Specs: Windows 7
suddenly computer started lagging and after a few restarts it didn't want to go to windows anymore and ignores the system recovery settimg...it just started to go into startup loops with no end...
i discovered it doesent recognise the hard drive with windows installed on it anymore and any other newer hard drives either. the only hard drive it's able to recognise is an old hitachi deskstar 128,5GB (model:HDS722512VLAT80) that connects with different cables. even though this hard drive is older than the computer, computer doesen't recognise it's original hard disk with newer cable connection...like it doesen't exist (but it works normally on other computer)

Boot with a HDD test utility floppy or CD (available from the particular HDD manufacturers websites), and test the HDDs surface & electronics. Depending on the utility, it may give you an error code you can look up to diagnose a failing HDD.

I'll take a stab in the dark and say you have a WD (Western Digital) HDD with failing electronics.

It also could be a hard drive controller (on the motherboard) issue, or a power supply issue, or a motherboard issue. If you have desktop PC, open the case & check the MOBO for bad capacitors.:

thanx for replying:)
nothing's wrong with the hard drives couse they work on another computer just fine.

problem is: the old disc that is conected on SATA works (i can run linux on it), but two others that i connected on PATA don't work (one of those 2 had windows installed on them and i guess that's why i can't get into windows anymore)- but both discs work fine on other computer (i copied the contents before doing anything extreme)...last thing i'm thinking of trying is installing windows on the old disk, then try if there's anything softwearish that could be fixed...:/

I too would take a close look at the caps.
Are they an X or a K...bulging or leaking.

A few bad caps errors.
Keyboard not found
Usb devise not found
Hd not found
computer stalls at bootup.

The WD is a Western Digital, you can D/L the DataLifeGuard HDD utility from WD's site; the other Barracuda is a Seagate HDD, and you can D/L SeaTool Disk utility to test that one.

MOOOOooove! OH and you're welcome!

there-s definitely no leaking capacitors...there-s one that-s maybe slightly bulging (normal colour and everything, but maybe just a little more non-straight at the top(really just a little))...is there anyway to test the mother board? why SATA connected disc is working and why PATA isn-t (i-m running ubuntu through an usb and is recognises the SATA disc but no PATA) is there a way to check the discs on this comp with ubuntu (it-s my firs time using linux...)....oh and the WD definitelz works, becouse it was working fine on my dad-s computer, before i tried replacing it with the baracuda one in my comp. and vice versa the baracuda works just fine on my dad-s comp, so i don-t think it-s the HDD. and also baracuda had windows on it when my computer stopped working and didn-t want to enter windows anymore, that-s why i thought it was HDD problem...if any of this makes any sense....

It'd make sense if you wrote it more clearly (haha), you have PATA, SATA, Windows & Linux? Ahh, OK, now I'm confused. I'm not fluent in Linux.

Just because a drive works or boots up in a system, doesn't mean that is completely healthy. I would try to run the thorough tests on all your HDDs if you can.

I haven't run across a really good, comprehensive, easy to use motherboard "diagnostics" utility, that points to an issue and tells you hey this is broken. There are MOBO test/diagnostics utilties (I haven't used all of them), that can test areas of the system and point you in the right direction of potential issues:

I have used TuffTest (not impressed), The Dell Diagnostics, PC Doctor (IBM, Gateway/Acer uses this one still I believe), EuroSoft Trial version (full version is expensive), they can point to motherboard component issues, but they don't always test EVERYTHING on a motherboard (like bad capacitors, or small component level diodes and sensors etc).

MOOOOooove! OH and you're welcome!

sorry for not being clear:P

let me start from the begining...at first my dad used the hp i have problems with and when he got a new one he gave me his old one, but took out the original HDD (the WD500gb). so i put in an old hdd that connects withSATA (same thing cd player uses), and another one (baracuda) that conects with PATA...everything was working just fine for about a year or two.

now, two weeks ago, computer suddenly started lagging...for one day everything went slow and i could hardly use anything but interent....than it went kaput(couldn't acces the windows anymore, not even through safe mode, and the startup went into loops:whatever i tried it went into loops...)

than somwhere in between it said on screen :imminent hard drive failure, do a backup and such...so logically i thought: hey there went my hard drive!..so i took the original WD drive from my dad's new comp and connected it...i can hear the power and something happening inside the hdd, but bios doesen't show any but the one connected on SATA...

now i installed windows 7 on the old drive that works and than connected the WD drive and checked the dics managment, but alas there's no trace of the PATA connected drive...

what i'm trying now is formatting the two drives that don't work on my computer and trying again...than i'mtrully out of ideas...yeah and i'll try the drive checkup tool...though nothing should be wrong with the WD drive since up until now it was in my dad's comp and he had no problems with itat all...

OH yeah and thanks for all the help and answers up to nowXD
