    Segate 13G ST313021A on Pentium 90 @ 125MHz:

    Average - 6.4MB/sec - now this is SPEEED! :p

    ...

    I wonder, if anyone have in operation slower HDD :D

    ...

    Therefore I wonder, if someone have a experience with replacing such SLOOOW HDDs with PATA to CF adapter and CF card(s)? The latest models promise very fast speeds - 160MB/sec is quite above PATA possibilities:

    ...and since the adapters are just wires, connecting the CF card to PATA interface (CF cards work on same PATA interface!) and only in best cases, you can choose the voltage (3.3V or 5V) and you get the power and activity lights:

    ...then there should not be any problem of using CF cards as old PATA HDD replacement(s). Only problem I hear, that there should be changed bit on the card somewhere, that change the device type from removable to fixed. Then it should act as normal HardDriveDevice.

    But maybe I missed something...? Do anyone have experience with this? Could someone share tips, software for the change (from removable to fixed) and experience in general?

    I've only connected an old system with a SATA PCI Card which basically i think did 166MB/s peak.... with that i connected a OCZ Vertex 3...... but for such an old system.. it was mostly wasted.

    What i did however use and continue to have opperating is i managed to snag one of the most powerful and still old enough to run windows 9x OS with intel's SATA controller running in IDE/Legacy mode with a 120GB Samsung 840 drive.... suffice it to say, formating the drive with a 32GB primary partition (os wouldn't read anything higher), windows ME booted in basically 0 seconds after being patched for running on 1GB of DDR ram and a ATI Radeon 8500 installed.

    That sounds rather cool. Did not the bios have troubles with the drive is big? Mine bios is limited to 32G, witch is a problem for finding a fast SSD and using PATA to SATA adapter...

    Well, since SanDisk is not going to reply, I tried with the default 5V setting the DeLock adapter I mentioned earlier with very old, 0.5G CF card SanDisk SDCFH. It does support PIO 4, but no DMA and the speed is very slow:

    Tested on ASRock 775Dual-VSTA (P4, 3.8GHz WinXP, alligned). Also works (or more precisely, get detected) on the target Asus TXP4-X, so so far, so good. Except the speed, lol.

    Now the question is - what voltage to use for the SanDisk Extreme PRO 32G CF card and how to change the removable bit to fixed, so there will be the caching in Windows possible.


    ...

    Well... first the good news: I tried 3.3V first and the good news are, that SanDisk Extreme PRO 32G CF card works well with 3.3V settings! There are the result, enabling Smart a 32bit mode transfer did nothing, PATA133 is supported, but it is not going to get higher. Sadly. Still, I think that this is a reasonable speed improvement:

    However, now to bad news. The CF card is completely useless, unless someone tell me how to change the removable bit to fixed. Period. You cannot use the CF card for anything w/o that. Two examples:

    I use Mini Tool Partition Wizard Pro to setup the drive on boot CD - it let me allign the partitions - when creating second partition (one 4G FAT32 for OS, rest for DATA and NTFS = usable settings for waza), it tells me, that I cannot use that partition under Win, as Win recognize only ONE partition on removable device. I was like... that it is, I'm screwed.

    So for lolz, I started the install. It want well even at 83MHz FSB with the ATI Rage XL card (IDE HDD refused to work under such conditions, it worked only when S3 Trio64 is used as graphic card at that clock), but then I get to the drive partitioning and problems arise. D partition is invisible (unpartioned space, lol) and there is no way to create a new partition there, because on removable drive, only one partition is supprted. So OK, I try installing and using only the 4G partition... but no! It cannot install, because this partition is NOT compatible with WinXP.
    (additionally the card then refuse to work in any PC... formating in my Nikon Coolpix 4300 camera was the only way to fix the caard :-O )

    So basicaly, w/o the change from removable to fixed, any usage of any CF card as HDD replacement is doomed.

    ...

    I'm quite mad at SanDisk - they should rename themselves as ScamDisk, because they are selling not CF cards, but CF compatible *) cards, with the *) exception for the possibility to change removable to fixed bit. I believe, that there is open possibility to lawsuit against SanDisk and any other CF card producing company, that produces products, that does not meet the CF card specifications. Because this is false advertising and misleading labeling of product. This is not a CF card, period.
