Now that you have the A411 connected you can try changing compression settings in Injoy, mine failed. The 0s at the end of the CID string switch off compression. One or both can be set to 1 to switch on, mine failed.

No change in version, I just copied a working Thunderbird 2.0.0.14 from my old computer to my new computer. (That suggests that the bug is something to do with the profiles, rather than with the code.) The "Download Actions" listbox is empty, and there is no way to add new actions.

Cheers/2 Ed. ---------------------------------------------------------------------------------- **= Email 7 ==========================** Date: Mon, 03 Nov 2008 19:51:15 +1100 From: Dennis Nolan Subject: Re: Compact Flash as internal disk - corrected Hi The promos for the latest CF cards boast a lifetime warranty, however CFA Information about CompactFlash ------------------------------------------------------------------------ CompactFlash® is a very small removable mass storage device. First introduced in 1994 by SanDisk Corporation, CF^(TM) cards weigh a half ounce and are the size of a matchbook. They provide complete PCMCIA-ATA functionality and compatibility plus TrueIDE functionality compatible with ATA/ATAPI-4. At 43mm (1.7") x 36mm (1.4") x 3.3mm (0.13"), the device's thickness is less than one-half of a current PCMCIA Type II card. It is actually one-fourth the volume of a PCMCIA card. Compared to a 68-pin PCMCIA card, a CF card has 50 pins but still conforms to PCMCIA ATA specs. It can be easily slipped into a passive 68-pin Type II adapter card that fully meets PCMCIA electrical and mechanical interface specifications. CompactFlash cards are designed with flash technology, a non-volatile storage solution that does not require a battery to retain data indefinitely. CompactFlash storage products are solid state, meaning they contain no moving parts, and provide users with much greater protection of their data than conventional magnetic disk drives. They are five to ten times more rugged and reliable than disk drives including those found in PC Card Type III products. CF cards consume only five percent of the power required by small disk drives. CF cards are also available for data storage using the Microdrive. CF I/O cards are available as modems, Ethernet, serial, digital phone cards, laser scanners, BlueTooth wireless, 802.11b WiFi LAN, etc. *Dual 3.3V & 5V Operation* -- CF and CompactFlash cards support both 3.3V and 5V operation and can be interchanged between 3.3V and 5V systems. This means that any CF card can operate at either voltage. Other small form factor flash cards may be available to operate at 3.3V or 5V, but any single card can operate at only one of the voltages *Connector* -- The connector used with CompactFlash is similar to the PCMCIA Card connector, but with 50 pins. Years of field experience in portable devices have proven the reliability and durability of this connector in applications where frequent insertions and ejections of the card are required. Other small form factor flash cards use connector technology that is not reliable or durable in these applications . *Shock* -- CF cards have an operating shock rating of 2,000 Gs, which is equivalent to a 10-foot drop. With typical usage, a CF card can be used for more than 100 years with no loss or deterioration of data. *Power* -- Typically consuming less than five percent of the power than that required to operate 1.8" and 2.5" disk drives, CF cards run at 3.3V or 5V with a single power supply. This makes them ideal for a range of current and next-generation, small-form factor consumer applications. *Operating System Support* -- Numerous platforms and operation systems support the PCMCIA-ATA standard, including Windows®, Windows XP, OS/2, Apple System 7, most types of UNIX, and many others. These all also support CompactFlash, CF disk drives and CF I/O cards.. *Data Reliability* -- CompactFlash data is protected by built-in dynamic defect management and error correction technologies. *Cost* -- CompactFlash provides the lowest cost flash storage solution for all capacities. With the built-in controller, a wide variety of low cost flash technologies can be used. The built-in controller lowers costs further by reducing costs in the host device and allowing defective flash chip cells to be mapped out, thus increasing flash chip yields. Sort of speaks for itself, don't it. Regards Dennis.

The larger the flash chip, the more the wear leveling built in to them can spread the writes around... so once you get into the gigabyte sizes, it takes some serious data writing to run into trouble. I have read an article which goes into the gory detail, but didn't bookmark the link. That said, there are two types of flash memory: single level cell (SLC) and multi-level cell (MLC). SLC is faster and more inherently resilient to the write exhaustion issue (at least an order of magnitude), but much more expensive. The very best SSDs (eg MTron) are SLC; most are MLC. I've also read that choice of file system has an impact on writes, and FAT (& FAT32) have advantages particularly with MLC flash as they are simpler and don't support niceties like access times. With Unix-like OSes, one can mount the file system without the access time updates. I'm not sure whether this is possible with HPFS, NTFS or the OS/2 JFS. I've also seen references to FAT32 being preferable over NTFS for performance reasons when using Windows XP on some of the netbooks with very slow SSDs (ISTR the Acer Aspire One drawing particular mention for this), but the exact reason wasn't clear to me. Because of the write issue, and the fact that there's effectively negligible seek time, you don't worry about trying to optimise SSD file systems (especially FAT/FAT32).
