There should be a bucket filled with drives to be tossed and a tub filled with drives to be kept. These need to be checked for mistakes. (If the tub or bucket is not there, use your best judgement to figure out which is which and go from there.)

Hard drive sorting is done in System Evaluation.

This is a graph with borders and nodes. Maybe there is an Imagemap used so the nodes may be linking to some Pages.

List of drives to recycle
  • 3 1/2 inch IDE hard drives marked less than 40 GB
  • 2 1/2 inch IDE hard drives marked less than 6 GB
  • 5 1/4 inch IDE hard drives, regardless of capacity (these are known as "Bigfoot" drives)
  • SCSI drives marked less than 72 GB
  • 50 pin SCSI drives
  • MFM hard drives (very old, see example)
List of drives to keep
  • 3 1/2 inch IDE hard drives marked 40 GB or bigger
  • SCSI drives marked 140 GB or bigger
  • 2 1/2 inch IDE hard drives marked 6 GB or bigger
When in doubt keep the drive.
Steps when Sorting
  1. First, check the recycle crate for drives that should be kept:
  2. Then check the incoming crate for drives that should be kept or recycled:
  3. Put any keepers in the TARDIS in the incoming drive area (near the door).
  4. Destroy any recyclers using the hard drive crank.
    • Ask someone in charge to check them before destroying the "recyclers" (even if you think you know how), and ask about the ones you think you want to keep.
  5. Stack recyclers in the crates. When crates are 75% full, put them on the cart to go to the warehouse.

How to tell a hard drive's capacity

Many hard drives are marked with their capacity. The words might be very small, but they're usually there. Look carefully for them. If that doesn't work:

Look for double labeled drives
Some drives have two labels. One generic label lists several different capacities and/or disk geometry. The other label is model specific and lists the model number. For instance one label might say:
MPC3032AT (3.24GB)
MPC3043AT (4.32GB)
MPC3064AT (6.48GB)
MPC3084AT (8.45GB)
MPC3096AT (9.74GB)
The other label says:
Model MPC3032AT
The drive is a 3.24 GB drive
Look for model number schemes
Some model numbers contain a hint as to the capacity of the drive. For instance, the western digital drives can usually be deduced by dropping the first digit in the model number. In the example above MPC3032AT is approximately a 3.2 GB drive and MPC3043AT is approximately a 4.3. Thus we can determine that the third and fourth digit in the four digit number is the drive size. By comparing similar models, you might be able to determine the probable sizes.
Google is your friend.
Try googling the model number and see if anything turns up.

Where to put them

  • Hard drives in the Recycle bucket go straight to Recycling after they are signed off by the Eval instructor and suitably whacked, drilled or squished.
  • Good Hard Drives go into the TARDIS
