Re: Compact Flash Cards

Tech-Archive recommends: Fix windows errors by optimizing your registry


XP and XPe can only see one partition on a removable disk. The problem used
to be when trying to implement EWF to protect the flash life.



Most CF cards don't have wear-leveling technology. XP likes to perform lots
of reads and writes to the drive (erase cycles), which can affect the life
of the flash. To protect the life of the flash you can use EWF or FBWF. Back
when we only had EWF, EWF want to create a second partition for the EWF
volume. Since most CF cards are ID'd as removable, one had to trick EWF into
RAM-REG overlay mode so a second partition is not create. This has been a
known and well discussed problem for a long time.



Now with FP2007 - there is a setting for RAM-REG in EWF and there is FBWF.



Removable is still problematic with preparation since DOS is needed to prep
the disk.

Un bel giorno Ralph A. Schmid, dk5ras digitò:

We switched from Sandisk Ultra II to Lexar Platinum II's - 80x. The
Lexars
were substantially faster, and the price was about the same. We haven't
had
stability issues with either brand.

Is there a tool available switching them into fixed disks? And do they
support DMA?

Can someone explain to me what is this thing of removable/fixed disks?
I've
used a lot of different CF with XPE, not doing anything particular to
switch them as fixed disk, and I've never had a problem.
