Frequently asked questions:

Can I update the firmware on my hard drive if it is installed in a Mac?

Set drive size with SeaTools for DOS

March 17th, 2015 40 views No comments

Some motherboard BIOSes limit your internal drive’s capacity. SeaTools for DOS can reset the capacity.

The ability to "Set Capacity" is a feature in SeaTools for DOS that will instruct the selected hard drive to report a size smaller than its true capacity during boot. The feature allows older systems with a BIOS limitation to boot with the drive in the system instead of locking up or freezing during the boot process.  Please be aware that the "Set Hard Drive Size" feature is no longer available in the current versions of MaxBlast and DiscWizard, so you will have to use SeaTools for DOS instead to set the hard drive’s capacity.  

Following this procedure will allow you to access your hard

Large Cluster Sizes Waste Disk Space

Cluster, cluster size, and slack

Large Cluster Sizes Waste Disk SpaceThe filesystem does not keep track of the disk space allocation (what space is used for which file and what is free) down to the byte level. That would require too much maintenance. Instead, the disk space divided into equal blocks called clusters. The filesystem then allocates disk space cluster-by-cluster.

This reduces the amount of overhead involved in tracking what is where, but also creates a side effect. If the file size is less than a cluster size, the filesystem still allocates a full cluster to store the file. The unused space in the cluster is thus wasted. For any file which size is not an integral multiple of a cluster size, there will be

Hello, So I want to erase the data off my hard drive from an HP pavilion so I can use it in my upcoming computer build to save money and I was wondering what are ways or programs and erase a drive. Thanks.

Erase_Hard_DriveYou may already know that "deleting" a file does nothing of the sort. But did you know that your disk drive has a built-in system for the secure erasure of data?

Before you sell away or throw your old Hard Disk Drive you need to make sure that you have completely erased it and this is important because you could have copies of your Important data stored in it and this can go to the wrong hands.
