heres my problem.. i have a 3 gig P4 with windows 2000 server.. 2
physical hard drives both on the primary ide.. a maxtor 80 GB with my
OS on it and a western digital 200 GB with all my important files
stored on it.. well a few days ago i started getting errors that said
my files r unreadable and corrupt.. this continued happening till i
got so many i had to restart the computer.. after starting back up i
went to that drive in explorer and i noticed the volume label was now
gone.. and when i clicked on it i got this error g:\ is not
accessible the parameter is incorrect.. i tried chkdsk and it did not
work.. i noticed that it says there is no file system anymore.. i
took the drive out and put it in my other computer and it asked me if
i wanted to format it.. i put it back in the old computer and it
still didnt work.. then i tried about 6 different data recovery
programs and recovered about 20 files out of hundreds of thousands..
i have another WD 200 GB with an exact copy of everything that was on
that drive i keep as a backup.. i hooked that one up to the secondary
ide and started burning all of it onto dvds.. when i almost had
everything copied.. my windows explorer froze up for some reason and
i had to restart.. when i went to the backup drive in explorer i
noticed that one also had no volume label anymore.. when i clicked on
it i got the same error.. i tried to recover that drive but i got
nothing at all this time.. thank god i copied most all of my files to
dvd.. i thaught i could never lose my files since i have so much
backup but this is insane... i reformatted one of the drives and i
started getting the same errors again and some files and folders even
dissapeared completely.. so i ran chkdsk before rebooting this time..
it didnt work.. but before it started up chkdsk started running
afterall and found tons of errors and i guess it fixed them.. it was
working fine again and i took the drive out and put it in my other
computer again and tried to access it and again it didnt work.. this
time it said it couldnt access it cause it was corrupt or something
like that.. it had all the same problems again.. i think it has
something to do with the master file table.. but the biggest problem
now is that i dont know whats causing this.. is it my OS or is it bad
hard drives?? i have absolutly no problem with the other 2 drives
(maxtor 80 GB) that i use for my OS.. once this happens do i still
use the hard drives?? ive done quite a few virus scans with 3
antivirus programs.. norton.. bit defender.. and an online virus
scan.. and everything came up clean.. i also ran a few hard drive
tests and they all said my drives were working ok... what is the
deal? can somebody please help me ive tried everything and searched
everywhere online.. i dont know what to do anymore!!
