Drives and Machines

This table contains a list of hard drives and how they were tested. Most drives, listed in black here, work perfectly in a variety of machines. Drives that don't perform as expected are listed in other colors. Overall, we think that about 95% of the drives out there work as expected.



Conner CFA850A 813MB zenith 8088/486 009 Master drive 80 pin Hargle MS DOS 6.22 Fdisk, format, boot, basic usage
Conner CFS210A 210MB Amstrad PC 2086, XT 8MHz 1.1.4 Master Drive 40 pin DavideG MS DOS 5.0 Formatted under Ms-Dos 5.00. It's recognized by bios and works, but I was not able to complete the startup sequence due to serious defects on last disk sectors. But I'm sure it's compatible since it's similar to the CP3201G.

Performance Testing

This table gives you an idea of what kind of performance to expect from a given machine (or class of machines).

Notes

It is expected that the drives we are using are faster than the target machines. So we don't list every drive tested on every machine - just the different machines.
Iotest - a very simple performance test. Iotest either reads or writes a large file (tmp.bin) and measures the elapsed time. If you do this on a new partition or a freshly defragmented partition it will effectively measure the data transfer performance of the controller and not the head seeking performance of the drive.
Usage Notes

DOS 5 and 6 Usage Notes

  • The largest drive size that DOS 5 and 6 can see is 8GB in size. Larger drives can be used but the additional storage will not be visible to DOS 5 or DOS 6.

  • The largest partition that DOS 5 and 6 can create is 2GB in size using FAT16.

  • If you can FDISK and FORMAT a drive but can't boot from it there might be drive overlay software installed in the Master Boot Record (MBR). There is an option on FDISK called /MBR that will write a new, standard MBR. It is non-destructive so you will not lose your drive partitioning. You should be able to boot from the drive after doing this.
