I got another computer with an IDE port, and used that to copy the data from the hdd to the card in a number of different ways, including: I partitioned the card with fdisk and made it active, then formatted the C drive with format. I attempted to follow the advice of Gober and I made a boot disk, copied and fdisk.exe, then booted the disk. I guess it would fall into the "PC compatible" category. The C/H/S values are different, and the CF card is about 4 times larger than the hdd. I don't know much about disk geometries, but I am pretty sure they are different. The original hard drive works fine, so I don't think there are any problems with corrupt data. The computer only has one IDE connector, and I couldn't get it to detect the card as either master or slave when the hdd was connected. That is why I tried using the original hdd in addition to the card, but then the card wasn't recognized. I don't have a boot floppy that I can use to see if the card is recognized. I am trying to boot DOS 6.22/Windows 3.1. If the card is the problem, how do I know which card to buy so that it is compatible? I have read online that some cards are more compatible than others, but no one seemed to have a problem with Lexar cards. What I would like to know is what would cause the computer to fail to boot from the card?Ĭould it be that that CF card isn't compatible? However, the card does work using a CF to USB adapter. In that case, the OS detects the drive, but fails to read from or write to it. I do not have any other systems with IDE connectors available at the moment, but I have tried connecting to the CF card with the adapter to an IDE to USB adapter on a modern computer. I checked the hex dump of the image and confirmed that it does have the magic number for a bootable drive. I tried connecting the old hard drive and the CF card, but in that case only the hard drive was detected. The status LEDs on the adapter indicate that there is power, but the data light only ever flashes once, very briefly, before the error is reported. The BIOS detects the drive properly and fills out the Cylinders/Heads/Sectors information, but when it tries to boot from it, it fails and says "Missing operating system". I used this adapter to connect the CF card to the computer. I bought a couple of 512MB Lexar CF cards, and I imaged one with the hard disk image using a CF to USB adapter. I used my Linux machine to take an image of the original hard disk, which is 160MB. I have seen many videos and articles describing using Compact Flash cards with IDE adapters instead of traditional hard drives, so I decided to try that. I am trying to fix up an old work computer I have from the early to mid 90's.Įverything works fine, but the hard drive makes a horrible clicking noise when it loads anything, so I decided to replace it.
