Hard Drive Compatibility Information

Question:

What SCSI hard drives are compatible for use with my K2?

Answer:

The K2 series were originally designed to support the use of SCSI-1 or SCSI-2 compatible devices (note the use of Ultra160 drives is also feasible with some modifcations, see here).

SCSI hard drive compatibility and capacity issues have been improved during the lifetimes of these products. To have the best possible compatibility, we strongly recommend downloading and installing the current version of the Operating system if you have a K2500, K2600 or K2661.

For K2000/K2vx owners, who must purchase the update and have it installed by a service center, we strongly recommend updating if you have a version prior to 3.52 (if you update to the current version 3.87, one advantage is that SCSI Load and Save times will be 2-3 times faster.)


OS Specific Compatibility:

K2500 (without KDFX) v2.98 or later
K2500 (with KDFX) 4.44 or later
K2600 v2.0 or later
K2661 any:

The K2500/K2600 can address up to 8 Gig of hard-disk space, in 2 Gig partitions. This is true for any hard disk formatted with the DOS-compatible FAT-16 format. Hard disks larger than 8 G can be formatted to make 8 G (in four partitions) accessible to the K2500/K2600. When properly partitioned, the K2500/K2600 files on your hard disk should be accessible to both the K2500/K2600 and your personal computer, if you're using one. We strongly recommend that you partition your hard disk from the K2500/K2600, although it's possible to partition it from a PC. We don't recommend formatting from a Mac, but a Mac will be able to recognize a Kurzweil formatted drive.

K2000/K2vx v3.52 or later
K2500 v2.13 through v2.96
K2500 (with KDFX) v4.0 through 4.32
K2600 v1:

These versions will work with a drive that is 2048Mb (2 Gig), or less. These figures apply to the available space AFTER the drive has been formatted. If a larger drive is formatted in DOS from a computer, and the first partition is kept within the above limits, that drive will function with the Kurzweil, since these versions do not support partitioning and therefore the Kurzweil only sees the first partition. If a larger drive is formatted from the Kurzweil, the drive will be formatted to 2048 Mb and the rest of the drive capacity ignored.

K2000/K2vx 3.18 or earlier
K2500 v2.08 or earlier:

These versions will work with a drive that is 1023Mb (1 Gig), or less These figures apply to the available space AFTER the drive has been formatted. If a larger drive is formatted in DOS from a computer, and the first partition is kept within the above limits, that drive will function with the Kurzweil, since the Kurzweil only sees the first partition. (K2000 requires v3 or later for DOS compatibility - if you have an older version, the drive must be formatted from the Kurzweil.)

For the K2000/K2vx with an OS of 3.18 or earlier, the following limitation applies to units without the PRAM option installed. For Backup and Copy functions, the combined size of the 2 drives must not exceed 1023 MB. This limit does not apply if PRAM is installed.


Internal Drive Installation Specifications:

Installation of an internal drive requires a hard drive installation kit.

  • The K2000, K2vx, K2000R and K2500R require the HDC-1 kit.
  • The K2500 keyboards require the HDC-25K kit.
  • The K2600 racks require the HDC-26R kit.
  • The K2600 keyboards require the HDC-26K kit.
  • The K2661 does not support an internal hard drive - only external.

These kits do not contain a SCSI hard drive.The internal hard drive must be installed by an authorized service center.The following specifications apply:

  • Operating Temp: 50 [C] 122 [F]; for K2000/K2vx Keyboards: 55 [C] 131 [F]
  • Height: 25.4mm [1"]
  • Width: 101.6mm [4"]
  • Length: 146mm [5.75"]
  • Mounting: Industry Standard 3.5" x 1" Drive

Power Consumption Specs:

The following charts show power consumption requirements for the various models. Regarding the K2000/K2vx Keyboard models, the low power consumption requirements mean that in practical terms, most drives above 800 Meg will draw too much power.

For the K2000, K2000VP, & K2vx Keyboards:

  +5VDC +12VDC
Start Up: <.625A <1.0A
Read/Write: <.625A <.75A
Seek: <.625A <.75A
Idle: <.625A <.75A

For the K2000 Rack:

  +5VDC +12VDC
Start Up: <1.0A <1.5A
Read/Write: <1.0A <1.0A
Seek: <1.0A <1.0A
Idle: <1.0A <1.0A

For the K2500 and K2600 Rack and Keyboards:

  +5VDC +12VDC
Start Up: <2.0A <3.0A
Read/Write: <1.0A <1.5A
Seek: <1.0A <1.5A
Idle: <1.0A <1.5A

Drive Vendors:

Finding suitable drives (especially those with low enough power consumption to be used as an internal drive for the K2000 keyboard and rack) can be very difficult these days.

Therefore we recommend the following web sites as possible sources for older, smaller drives. Of course, there is no telling how long these older drives will continue to be available.
