Improved Hard Drive Capabilities TASCAM 788 v2.0 Addendum • 7/2002 Edition6Section IIImproved Hard Drive CapabilitiesOVERVIEW RE-FORMAT (PARTITION)Before v2.0, the 788 could identify and use up to 16GBfrom a single hard drive. v2.0 increases the usable areato 64GB of space. Be aware that this does not magicallyincrease the size of your hard drive, it merely increasesthe amount of space that the 788 can recognize. You’llhave to obtain a larger drive (either internal or external)to take advantage of this.Keep in mind that the maximum capacity of a song is7GB. This provides almost 1 hour and 45 minutes of all8 tracks at 24 bit. If you need more time, you mayneed to break the recording into a few song files.About PartitionsWhenever a system is writing to a hard drive, the dataon the hard drive has to be stored at an “address”. Ashard drives get bigger and bigger, more and moreaddresses are needed. Eventually, you’ll end up in asituation where the system cannot provide any moreaddresses, and the extra space cannot be used.The computer industry ran into this problem in the mid-90’s. To get around it, they allowed the drive to havemultiple “partitions”. Essentially, they broke the harddrive capacity into smaller, manageable pieces. To thesystem, each partition appears to be a different harddrive. In reality, they can all be from the same drive.Before v2.0, the 788 could use up to 4GB in a partition,and allowed up to 4 partitions per drive. This allowedfor a total of 16GB of space on the drive. With v2.0, thepartition size is stepped up to 16GB. Since you can stillhave 4 partitions, that offers a total of 64GB of space.A Note About Hard Drive Sizes:If you replace your internal hard drive with a largerdrive, or connect an external drive, you may notice thata drive will not yield all of the space that a drive quotes.For instance, a 60GB drive may only give you 56GB ofspace once mounted on the system.There are two main reasons for this:1 - Drive manufacturers will typically advertise“unformatted” capacity. Some space is used just informatting the disk.2 – Most drive sizes are quoted with rounded figures. Inthe chart at right, you can see that each step up inmeasurement actually occurs in steps of 1024.However, the quoted size will round to eventhousands. This minor difference adds up to about a7% variance between the drive's quoted size and itsactual capacity.Occasional formatting of the hard drive is generallyconsidered to be “good housekeeping” on any system.Since the 788 can now hold such huge amounts of data,our engineers felt it may be cumbersome to back upeverything, then format the whole drive, then restore allthe data again.To make this easier, they decided to offer the ability toformat just one partition. It's kind of like giving you theability to clean one room of a house at a time, ratherthan cleaning the whole house at once.So, if you want to reformat partition 2, you can justcopy the data you want to partition 1, then format onlypartition 2. Very simple!Please keep in mind the difference between the FORMATand RE-FORMAT commands. FORMAT clears out thewhole drive. This is still needed if you choose to changethe partition size, or if you want to wipe the entire driveclean. RE-FORMAT only formats one partition.Step By Step Partition Formatting1) Press MENU.2) Select , and press ENTER.3) Select and pressENTER. The 788 will displayeach of the partitions thatare currently available.4) Highlight the partition youwish to format, and pressENTER.5) The 788 will verify that you want to reformat thepartition. Press ENTER again to confirm.Real Hard Drive Size(Actual Storage Capacity)1 GB = 1,073,741,824 Bytes1024 bytes1024 KB1024 MB1 KB (kilobyte)1 MB (megabyte)1 GB (gigabyte)===Rounded Hard Drive Size(Quoted Drive Sizes)1000 bytes1000 KB1000 MB1 KB (kilobyte)1 MB (megabyte)1 GB (gigabyte)===1 GB = 1,000,000,000 Bytes≈ 7%Difference
