Hard Drive Partition inaccessible

September 25, 2008 at 06:34:58
Specs: Win xp sp2, P4 3.0 Ghz 512 MB ram
i have 2 hard drives 80GB & 160 GB respectively with a total of 8 partitions.
now from a while i feel my hard drive acting funny, windows going corrupt now and then. scanning my hard drive on every bootup even when i properly shut it down.
Now the most strangest thing has happened. My J Drive wont open up..when i try it open it it says "the file or directory is corrupted or unreadable.

now what do i do guys? any help? any free software out there i can use to scan and repair my hard disk partition?

What program have you used to create the 8 partitions on the two hard drives? Partition Magic?


Check out the following thread and try what worked for someone else with the same problem. Good luck.

Watch the start up screens to see if both hard drives are properly identified by model and capacity.

Which hard drive is not seen correctly?

What is the answer to XPUser's question?

"and yea both hard disks are identifying"

What I was looking for is if the 160GB is shown as a 160 in the POST screens.

Why do you keep on re-installing Windows?

Chkdsk /r will do a pretty good check of all the sectors on a disk. It will assign alternate sectors for any defective ones.

But I would start to worry about the reliability of the drive if bad sectors start showing up.

If you re-installed WinXP with a full installation CD that does NOT contain at least SP1 the drive may not be accessable if over 127GB. Solution is to install a service pack.

I hate it when people ignore my posts.

If you don't want to run chkdsk, you can find all the hard drive manufacturer's diagnostics at:

If you want help read the responses of others and then respond back with all the answers.

I asked multiple questions and you don't answer them. Aegis suggested something to try that may fix the problem.

Dear Aegis :

Thanks a lot for ur posts my friend..chkdsk doesnt helps me as everytime i boot my pc it runs chkdsk by itself and gets stuck on verifyng folders n files. i tried running chkdsk /r. i can access the partition now.
However i was thinking of something else that might be causing the problem... actually i have 2 hard drives (160GB sata with NTFS + 80 GB with FAT 32 file system) so 4 of my partitions are on FAT and 4 of them on NTFS. i was thinking maybe that might be causing problems when i copy files from a fat32 partition to an ntfs, causing to run chkdsk on every bootup. although i dont know why the chkdsk thingi freezes.
ill check the link u gave me and let you know.

OTEHILL : thanks for your reply friend but i have windows XP SP2. and it was running quite nicely until things start messing up.

the Current situation: ok now i can access all the data however, my pc constantly runs chkdsk on every startup (particularly scanning J: and H: drives) and if i dont cancel it, it gets stuck on step 3 of chkdsk.

any clues?

You don't get it. You think all was good but it may not have been.

I don't even know if the issues you have are related to 48 bit LBA compliance because you refuse to answer simple questions.

If you know more about your problems than the folks here then why are you posting here?

Look at the links below.

Dear Otehill,

You sound merely pissed and are being sarcastic instead of helping. Apologies if i offend you in someway, but iam just keeping you guys updated on things iam trying to do. you only asked me about the SP thing which i told you that i have been using win XP with SP2 since always. i.e 2 years back. I reinstall windows one in every 4 months or so because of such heavy usage, it builds up a lot of crap files and slows down so i refresh it for the sake of it.

i am fully 48bitLBA enabled with XP SP2 and a latest version of bios. anyway ill try to answer your questions now. thanks for your help.

and by the way i tried doing chkdsk with r switch on my drive J. its been 7 hours and its still running and it has done like 45% of my 40 gb partition. why is it taking so long?

oh by the way. the chkdsk -r thing is taking this long on step 4 "verifying file data" (stage 4 of 5)....

does this mean my data is corrupt or something?

I can't help if you won't answer questions.

If you have no idea what 48 bit LBA is why haven't you looked at the links I provided? Both deal with it.

You were not clear on whether or not your 160GB disk shows up as a 160GB, and not something smaller, during the start up screens.

This would determine if 48 bit LBA compliance is the source of your data corruption.

Why don't you just assume that questions are asked for a reason and answer them. I am not the only one in this thread that feels that way.

Are you running chkdsk from within Windows?

I looked at the links. I have no LBA issues because

1) in startup it shows my drive as Master Disk : LBA, 160GB

2) I have SP2.

Yes i was running CHKDSK from within windows. It took about 10 hours to complete with the following results:
