I purchased a 60GB (80GB/100GB/120GB/160GB) Drive, but when I connect it to my computer, it only shows as 55.8GB. Is something wrong?
The 60GB (80GB/100GB/120GB/160GB) refers to the unformatted capacity of the hard disk drive. This is the size of the drive before it is formatted. Formatting a hard drive, is the process of preparing it for use. The drive is divided into blocks and tables are created to manage the blocks. This process consumes some of the drive's initial capacity.
Therefore, 60GB is the unformatted capacity of the hard disk drive and 55.8GB is the formatted and ready for use capacity. This is not specific to the Store-It Drive; in fact this is common to all hard drives. The unformatted capacity of any hard drive will always be greater than the formatted capacity. Depending on the size of the disk, more or less space will be consumed. Formatting will consume less space on a smaller disk than it will on a larger disk. For example, a 60GB unformatted hard drive may show up as 55.8 after formatting.
A 250GB hard drive might show up as 228GB.
