Hi

First of all i know this is wrong forum, but by experience i know here is the only place to get an answer so:

My computer had loads of virus that couldnt be removed by norton so i thought i format it, but i get errors all the time and windows install loops and when format in dos it takes 3 sec. I tried everything but no luck, could this be coz there still is virus in hdd bootsector and if so how can i remove it ???

Remove the prior master boot record using a Win98 floppy even if your install is XP, use the FDISK to remove the partition be it XP or 98 then reboot and back at the A:\ prompt run FDISK /MBR 2 times that should clear the master boot record EEPROM on the hard disc of the boot virus.

Check your BIOS it could have a master boot record virus detector built into it most of the new MoB do.
By default most of them are also not enabled!!

Enable yours if it's got it.

DO a new DOS format then later if you are installing XP remove the DOS format then do it in NTFS if you wish.

FDISK then Format alone does not clear the EEPROM on the hard drive that can also get infected and you simply as you have done re-install your Operating system and bring back the same problems.

FDISK /MBR

Okay, you'll need a two ton industrial electromagnet, a taser, a sledge hammer, some duct tape, four D sized model rocket engines with fuses, a model rocket ignition kit, and a small can of lighter fluid...

Or, if you don't mind waiting, you could put the drive in a lightly padded envelope and send it to yourself through the mail, making extra special care to have the package marked "<font color=red>fragile</font color=red>".

Of course using the drive after you've <i>cleared</i> it might be tricky. :evil:

Download the disk diagnotic utility software from your disk manufacturer's website. Preferably do it on a virus free computer and write protect the disk. Boot with a clean floppy, run the program and choose to do what is often referred to as a Low Level Format. This rewrites every bit on the drive as 0 thereby erasing any possibility of a virus on your drive. Reinstall the OS using clean disks only. Enable boot-sector protection in the BIOS if you have it.

did what u said but after convert to ntfs and format it said couldnt format. I´m using 2 sata in raid 0 so i thought maybe i have to to it on each one but with only 1 sata drive fdisk says cant find any drives! this suxx :C

Ok sorry yet again I get sucked into the SATA drive problem.

I guess I am an old computer geek and keep forgetting that yes even myself now use SATA.



Intro

SATA (Serial ATA) is the new standard in which to connect Hard Drives and soon, Optical drives (DVDRWs, DVDROMS, CDRWS etc) to motherboards. SATA improves on the old IDE interface by offering faster transfer rates, neater cabling, and future-proofing (IDE will begin to be phased out in a few years). Although most SATA drives at the moment aren't any faster than standard IDE drives, new drives are emerging that offer faster transfer rates than IDE limits us to.

As SATA is a new standard there is some confusion over compatibility. Some PSUs (Power Supply Units) need adaptors to connect to SATA drives and older Motherboards don't have SATA support at all. To add to the confusion, when Windows XP was developed SATA wasn't yet a recognised standard so XP doesn't detect SATA drives when you are installing for the first time.

Here is a guide on how to get started with SATA and how to install XP on your new SATA drive:


Before you buy

If you are planning on getting a SATA drive first make sure your Motherboard supports SATA. If your Motherboard doesn't support SATA you can always get an SATA controller card but my advice is to avoid these.


What you need

SATA data cables

SATA drives use the new SATA interface and so don't connect to the Motherboard using normal IDE cables used by IDE HDs and optical drives. However, most Motherboard's come with 1 or 2 SATA data cables in the box and if they are not included you can purchase them separately.

SATA power cables

SATA drives also use a new type of power connecter rather than the standard 4-pin Molex connectors used by IDE HDs and optical drives. Most newly developed PSUs include the SATA power cables but if your PSU does not you will need an SATA power adaptor which can be found cheaply and easily.


Installing Windows

Once you have the drive(s) connected you are ready to start installing XP.

Master and Slave

Remeber since it's serial you can only have one device per SATA port/cable so SATA drives don't have jumpers. On the Motherboard SATA1 Port is for the primary device, SATA2 port is for the secondary device etc.

SATA controller driver

Your Motherboard or SATA controller card requires a driver to work properly. If you did not get a Floppy Disk with the SATA driver included with your Motherboard you will have to make one. The SATA drivers can be located on the installation CD that came with your Motherboard or preferably, download the latest SATA controller drivers from the manufacturers site. Once you have located the drivers copy them to a formatted floppy disk. Make sure they are in the root directory i.e. not contained within any folders.

BIOS settings

When you turn on the PC hit the Delete key when prompted and you will enter the BIOS (Basic Input Output System). Here you set the first boot device to be the CDROM drive, the option is usually found under the Advanced Options section but this depends on your BIOS and you may have to look around for it. Once you have done this save and exit.

Installing the SATA controller driver

Once you have set the PC to boot from the CD make sure the XP CD is in the CD drive and start the installation as per usual. Within the first minute or so of the installation Windows will prompt you to press F6 to install RAID or SCSI drivers, do this. Windows will continue to install then ask you to locate the driver. now with the floppy disk created earlier in drive A: select the driver and hit Enter.

With the SATA drivers installed you can now continue the Windows installation as usual.

BIOS settings revisited

Once Windows has finished installing you will need to make sure the PC is set to boot from the SATA drive. To do this make the first boot device SATA if the option is available. If not you have two options: HD0 - If there are no IDE HDs present, or SCSI if you do plan on running an IDE HD as a secondary device.

To do one drive only, you need to shut off raid in bios.
Are you sure your problem isn't from your memory? You may have problems due to the OC.

I tried to write zero to both drives and i dont have the loop problem any longer. I can succesfully install windows on 1 drive but not at both in raid, i think the problem is when to chose where to install windows i see both the partition i made 72gb fat32 and 1 non partition 36gb and when i try to format and konvert to ntfs i get error. i remember i had this problem before but then somehow i managed to see only 1 partition atlast, cant remember what i did though. I think that i see 2 partitions in windows install is the reason to my problem, but what can i do?? tried everything!

Having 2 or more partitions should not effect your install at all, I currently have 4 NTFS partitions on my SATA RAID0 array.
Use FDISK to delete all of your partitions, then run the windows install (remembering to press F6 to install your RAID drivers)the windows install should be able to partition the drive for you and then let you format the partitions with NTFS or FAT32.

What RAID controller are you using?
March 16, 2005 5:07:12 PM

the problem is i have only 1 partition but i also see a non partition 36gb who shouldnt be there!

Ummmm are you sure you have set up your drives in a RAID0 array? You see a single 72GB partition and one 36GB one right?
March 16, 2005 11:09:54 PM

i see the 72gb fat32 partition i made in fdisk and a 36gb area that doesnt have a partition and shouldnt even be there!

guess i´m doomed to use only 1 drive then, how the heck did i get it to work in the first place! maybe i try at the hdd forum and i might get an answer from a hdd gosu within this year maybe

Turns out i had to connect the drives to sata 1 and sata 2 i order to install OS on them. Btw ppl say u must have ur drives at 3 and 4 in order to OC and when i try moving them back to 3/4 after install i only get black screen when windows is about to boot, what can i do ? ? ?

If your rig runs fine with the drives on SATA 1 and SATA 2, why the hell wouldn't they work with your CPU overclocked? What possible difference would that make to a SATA port?

Some SATA ports on boards aren't locked, and so overclocking pulls the SATA bus out of spec.

exactly! apparently sata 3 and 4 is locked but not 1 and 2 on my board.

coz windows wont even boot if u oc the sata ports to much. btw im so sick and tired of nforce/gt6800 combo anyway, so i will order a Via mobo on monday anyway.
