No. None being manufactured anymore. The last one was the Fuji Finepix S9000.
Believe me, I understand where you are coming from. Memory used to be a big investment, it was $1100 CDN for a 1 GB CF when I purchased one in 2002. Because of this, it was important when changing cameras that you could continue using the same cards.
This is no longer the case. ...

There are two utilities from CGSecurity that might help.
TestDisk - Allows direct access to disk data and file recovery from corrupt partition tables.
PhotoRec - Specifically targeted at recovering photos by identifying byte patterns in images (& video) files.
Depending on what has caused your card to fail will depend on which of these tools will ...

Can you distinguish if it's the card that is inaccessible, or just it's filesystem? I know in Linux, you can access the raw device and try to get you data out of that (which should be possible, since it's usually just sequentially stored JPEG files).
On Windows and Mac, you can try recovery software recommended by SanDisk, demo version which shows you what ...

I found myself in the same boat about a year ago, and I considered picking up an SD-to-CF adapter to use SD cards in my camera. All the research I did, however, showed really spotty results for these adapters, so I bagged that idea and bought a couple CF cards and a USB card reader for the CF cards.
The ultimate driver for me was reliability. At the end ...

I can't find any specifics for the 7D that are helpful. Normally I would look to the Rob Galbraith CF/SD Performance Database, though the newest cameras aren't listed there. According to the dpreview.com 7D review's performance section, the camera maxed out when shooting raw with a Sandisk Extreme Pro card. So, one conclusion could be that the camera is ...

File deletion essentially means removing file entry from file system (file system contains information about all location and size of all files on disc or memory card). If something goes wrong file system may become corrupted, rendering card inaccessible (all the data may be still there, but without filesystem you can't tell where one file begins and another ...

For video I believe the requirements would be a card that can write 10 MB/s (mega bytes per second). This equals to 66x speed for a Compact Flash card. For shooting stills it's possible to get a longer burst with a faster card. If you want maximum burst length, get the quickest CF card you can afford.
The math would be: 66 * 150kB/s = 9900kB/s ~ 10MB/s

The speed at which you can import the photos is governed by the card type and the cable you use to connect to your computer, so first make sure you have the fastest type of card available. Lexar make a Firewire 800 card reader which is stackable, so you can link two or more together as FW800 allows you to daisy chain devices in series.
If you use a Mac you ...

Your first question should be How do you prevent blown out skies without underexposing other parts of the image? because you can always expose for the sky.
It turns out the answer is the same for a compact or a DSLR because all cameras have a limited dynamic range. Yes, modern DSLRs have more dynamic range than your S90 but that only moves the point at ...

Your entire existing infrastructure is geared towards SD cards, so why change?
CF cards are generally more robust, which may or may not be a factor for you.
Personally I find a 1 year life for that adapter extremely short, for me it would be enough reason to not get another one (but maybe there are other makes and models out there that are higher quality).

If you are able to get to the card at all, you could try using Recuva from Piriform, Inc. It is a free download, and I have used it to get back files that were accidentally deleted.
One of the features listed is:
Recovery from damaged or formatted disks
Even if you've formatted a drive
so that it looks blank, Recuva can
still find your files ...

I'm not sure what an "Untouchables Firmware" is (my assumption is that it's some 3rd-party firmware) but it sounds as if the camera has somehow formatted the card into a format that only it can read. If it's happened with a second CF card, my suspicion is that there's a problem with the camera.
Can you install a default/Canon firmware on the camera and see ...

The file system for the camera (given the era, the cards available at the time and their price) is probably FAT (FAT16). There's no indication anywhere that the camera is capable of using FAT32. If that's the case, you won't be able to use cards bigger than 2GB, and may find that only 1GB is addressable.
While they're not nearly as commonly available as ...

Since neither Windows nor the camera can read the card, I think the most likely scenario is that the changes Windows were about to write to the card were interrupted halfway through.
Such interruptions will corrupt a file system for sure, and could happen if you just unplug the card instead of going through the Windows "safely remove hardware and eject ...

CF cards were used back then because they offered higher write speeds than smaller memory cards and some even offered then gigantic capacities by utilizing small hard drive inside.
However, these days SD cards rival CF in speed and capacities are already beyond practical. For example, 8GB Class 10 SDHC cards I use in my SDLR hold around 700 raw images per ...

Don't forget, that the USB channel has bandwidth limitations. USB 2.0 spec High Speed is 480 Mbps (megabits per second). This means that an 8GB card can theoretically transfer in 134 seconds. Firewire 800, can do this in 80 seconds (Firewire 400 in 160 sec).
Now, this is theoretical, because every USB or Firewire device connnected utilizes bandwidth. If ...

Opening files from a card on Windows should not corrupt it, since that action is only doing a read, and not altering the contents.
You should never format, or delete images on anything other than the camera, primarily because of the various disk formats and implementation of them on computers.
Most cameras use the Windows format known as FAT32. This ...

My question is, can a card get corrupted by using Windows to delete files from it and how can I try to recover the pictures on it?
Yes, a card can get corrupt just by inserting it into a card reader, not only by deleting files. I had a multi-card reader and only the xD slot would corrupt the card. I could view them but once it was taken out it was no ...

I don't know how you could tell the age of the card, but I think it is more important to know roughly how many shots it has recorded, to format it regularly, (the formatting will remove wilting parts of the card), and, depending how often you use it, throwing it away after an amount of time that suits you, ie. a year maybe. Then mark the new one with the ...

I have one of these and they are great; you can download 4 CF cards at a time:

Compact Flash theoretically has a limit of 128GB or greater. The S1 seems to be 6 megapixels, so on a 4GB card you could hold 600+ images
If this is the S1 Pro, then according to this link:
Compatible Media (As of July 2000 ): Microdrive: IBM: 340MB; Compact
Flash cards: Sandisk: SDCFB-16t32140/48/64/9a1128| | Lexer Media: 4x

I happened to notice this from the FAQ I referenced in the answer to your last question:
Question:
If I purchase a high performance CompactFlash card for my E-10/20N, will it reduce the time
writing to the media.
Answer:
No, the writing time is controlled by the camera, not by the Media.
In other words, it won't help.
(This mentions the "N" ...

The E20 FAQ from Olympus says that CompactFlash-interface microdrives up to "1gig" are supported. That doesn't necessarily mean that bigger cards won't work, though — unlike SmartMedia, CF doesn't require device support for larger capacities, since there's a standard interface with "smarts" in the card itself. ("Smartmedia" is an Orwellian misnomer; it's the ...

Based on your tests, it really sounds like a hardware problem with the camera. Given that you're seeing the same symptoms with several memory cards, it's likely the camera (not the cards) that is the culprit.
One option would be a repair on the camera, but as you note this is an older unit and you could probably pick up something like a T1i or for not much ...

Thus far, Eye-Fi does not support compact flash. They have a page on their website that lists known issues when using an adapter. These issues include a reduced wireless range of the Eye-Fi card as well as a potential for file corruption.
I'm not aware of any competitor's products which offer similar functionality in a CF card. I do note however that it ...

I'm currently in the process of using ddrescue to recover photos from a corrupt CF card (I believe hardware failure).
The problem I have is not only parts of the filesystem/files being unreadable, but when I attempt to read a specific part of the CF card, the disk stops responding entirely, which makes it quite difficult to import files off it.
I imagine ...

As Simon wrote, photorec is a good tool to recover lost data, not only image files. I the past I recover jpg files with success, but it used signatures to find the files, and I don't know if it has signatures for raw files.
Just a tip, first copy the content of the card with dd and the used photorec with the image created by dd. By making this one-time ...
