Convert lba to cyl, head, sector

The problem with CYL/HEAD/SECTORS is that disk-drives have gotten *MUCH* too large -- the limited size of each field mean that a new scheme, namely LBA (Logical Block Addressing) had to be created to deal with disk-drives that are 1000 times too large (4 Terabytes versus old 4 Gigabytes).

So, if you have 312,500,000 sectors,
and each sector is 0.5 Kilobytes,
you have 156,250,000 Kbytes,
or 156,250 Mbytes,
or 156 Gigabytes.

External drive - red light stays on and computer frozen

If the computer is going ballistic when you plug in your external drive that is an indicator that something is fubar with your Seagate drive. And a data retrieval asap is in order.

Remove the drive from your external case and hook it up directly to your regular computer as a slave drive and see if you can get your data off of it. Hopefully its condition will allow your main drive to bootup , then you can go into windows explorer, and transfer all of your needed files to a usb stick or perhaps your main drive if you have the room. It is not uncommon for a drive to be so bad that even its mere presence will not allow your main drive to boot up!!!!!! Not good. In a case like that you might try to install the drive in a docking station and then hook it up to an up and running computer - you might get lucky and get access to its innards. But do not be surprised if you cannot. Hard drives are like humans - they are all destined to die - you just do not know when.

If you have bad sectors on the drive that are responsible for its condition, you might try to run check disk on it to repair the bad sectors but knowing that if it locates and repairs bad sectors the data in the bad sector may not be saved. But anything you save is better than nothing so it is worth the risk. Then after the retrieval you can run a low level format on the drive - this procedure will erase everything on the drive in addition to permanently blocking out any and all bad sectors on the drive. If it works it will be like a brand new drive.

When drives are manufactured nada is perfect and they always have more capacity that the stated amount. When the low level format is run on new drive, the bad sectors are blocked out and replaced by "surplus" sectors so that stated capacity is met.

Ready for some "fun"?

What numbers off the HD do I use to set up the CMOS on the mother board under "User" hard drive?

Use automatic detection if it is available; if not use the following:

Size: Usually set automatically depending on the settings for heads, sectors, and cylinders.

Cylinders: The number of cylinders on hard disk. Should be written on drive.

Heads: Number of heads. Should be written on drive.

Write precompensation: Not much used on modern drives. It was used to accomodate drives that had the same number of sectors per track, including both the inner and outer tracks. On SCSI drives

, set this to -1. On IDE drives, it is not necessary to worry about it as it will be determined automatically.

Landing zone: Used for drives that don’t have auto-parking. All modern drives do, so just set to 0.

Sector: Number of sectors per track. It’s often 17 for MFM drives, and 26 for RLL drives.

Wrong Hard Drive capacity

first you change ribbon data cable which connect hard disk

it may not be supporting more than 32 gb capacity.
first you only connect the only hard disk test for detection

Quantium 10.2 gb fireball CX10A011 specs. ie sectors, mode, etc.

The specifications to enter the information manually, are on top of the harddrive. Kind of hard to discern, huh? That's because harddrive sizes from 6.4GB through 20.4GB are listed on top.
C/H/S = Cylinders/Heads/Sectors
The Quantum Fireball CX10A011 hardrive is a 10.2GB harddrive.
You will see -> C/H/S....10.2 - 16383/16/63 on top.

That is ,
16,383 Cylinders
16 Heads
63 Sectors

As for the 40GB model, it should be similar. If not, come back and post.
