My boot up time, from the grub menu to login screen, is about 30 seconds. This is a lot faster than before, which was at least a minute and more if I remember.

I'm sure the 1.8 ssd from transcend has not been covered.
Maybe you can be the first one to try it, the connector looks good to me.

Creed,

Thanks for the heads up, though nowhere near as Slade's 1 second... Still wondering how it's achieved

Hey guys, an update...

I've now installed openSUSE 10.3 and I've used it for two days.

Two partitions (one on each of the cards) as raid0 /, 150mb /boot and the rest as dm_crypt/lvm /home.
No data corruption yet

It seems that openSUSE (2.6.22.13-0.3-default) doesn't have the same problem as ubuntu gutsy, but it has one caveat. One harddrive is running pio6....

So my raid0 is worthless when one cf is running pio. The whole system is lagging when I copy files, both to /home and /.

hdparm -I /dev/sdb

sdb:
DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 (?)
Cycle time: min=120ns recommended=120ns
PIO: pio0 pio1 pio2 pio3 pio4
Cycle time: no flow control=120ns IORDY flow control=120ns
Commands/features:
Enabled Supported:
Write cache
* CFA feature set
* CFA advanced modes: pio5 *pio6
sda:
DMA: mdma0 mdma1 mdma2 udma0 *udma1 udma2 udma3 udma4
Cycle time: min=120ns recommended=120ns
PIO: pio0 pio1 pio2 pio3 pio4
Cycle time: no flow control=120ns IORDY flow control=120ns
Commands/features:
Enabled Supported:
Write cache
* CFA feature set
* CFA advanced modes: pio5 *pio6

hdparm -t /dev/sda
/dev/sdb:
Timing buffered disk reads: 10 MB in 3.01 seconds = 3.32 MB/sec
seneca@odysseus:~> sudo /sbin/hdparm -t /dev/sda

/dev/sda:
Timing buffered disk reads: 62 MB in 3.02 seconds = 20.53 MB/sec

Having a drive running udma1 versus pio6 makes a whole lot of difference.

Please post your benchmarks to compare!

Could you please provide feedback? I really want to research more about it before purchasing.
Thanks,
That drive does not exceed mwDMA2 (16.6 MB/s). After reading that I decided not to buy one.

Random write is bound to be bad just like other Transcend products. If you are happy with mwDMA2 and only a single drive in X40 you can try TS8GIFD18. I would not.

With X41 another detail needs to be considered: Most SATA-PATA bridges support UDMA and PIO but not mwDMA. I do not know which bridge is built into X41. So I do not know if X41 supports mwDMA at all. If not the disk has to run in PIO mode.

yeah, I tried that drive as well. It was painfully slow. NOw, I do not know what running in PIO mode means, but when I replace the original HDD with that, it takes over 5 minutes to start up. However, once windows boot, the time it takes to open applications is significantly faster than before. Battery life is the same, but there is no noise. Overall, not worth the money and I returned it

Asked Delkin technical support four weeks ago if the card identifies as 'removeable drive' or 'fixed disk' in true IDE mode. Did not receive an answer.

Just like Microdia: Asking the same question regarding this 32 GB card. Two weeks passed. No answer.

Can this process be used to convert any removable drive to a fixed disk???

I wanna contribute my own experience with Super Talent's SSD.

I got a Super Talent FHD32GC18M and it doesn't work on my X41t. Not only my X41t cannot see this SSD, my T42p also doesn't see it, no matter where I put it (main HDD bay or ultrabay). I am almost sure that this SSD is not defect since somehow one can see this drive under T60 (but not before login into VISTA). So... no hope on a real SSD on X41/t.

Originally I think even my X41t might not work, it should work fine on my T42p which eats all the IDE HDD. However, it is not the case at all. So... the only possible SDD which might work on X41 will be the PQI one. However, I don't dare to try this again.

Hi, I am testing Delkin 16GB UDMA CF with Addonics CF-to-IDE converter on my Thinkpad X41 Tablet.

Fortunately, I was able to install Windows XP Tablet 2005 without any problem.

(I just formatted the disk NTFS, and installed Windows XP. I was worried about the "removable/fixed" problem - Even though it was shown as a "removable" device, after formatting the disk NTFS, I was able to boot from the CF card.)

The problem I'm having is after the booting, the HDD Read/Write light doesn't go off. I don't know what process is continuously writing (or reading) the disk, but it doesn't stop!

(I waited for more than 20 mins...) and obviously, because of the HDD is continously being accessed, the system performance is terrible!

[I'm not saying Delkin CF is really slow. I'm just saying something is wrong and keep trying to access the HDD.]

I installed Windows XP Tablet edition (Clean install). And turned off the page file (or virtual memory) option, indexing service. I have 1.5GB RAM.

After killing a svchost.exe process (and its child processes), it stopped accessing the HDD. But, it started again as I started the Windows Update process (since I just did the clean install). [After killing the process, the performance was increadible

... but I cannot say it for sure since no programs nor drivers has been set.]

Do you have any ideas what the process is and suggestions on how I should fix it? (Otherwise, I'll just have to try another clean install - which by the way takes few hours - to see what happens with the default option.)

PS. I believe someone questioned what will happen if he/she uses two CF cards to Addonics CF-to-IDE converter on X41 (and X41 Tablet) model. And someone answered it'll only detect the primary CF card.

- Yes, it is true. I tried it, and the secondary CF card is NOT detected.

qviri · #222 Post by **qviri** » Sun Dec 23, 2007 2:13 am

svchost is an executable used by the operating system to run its "services" (mostly servers, drivers, system functionality, and the like). You can't tell what's causing the hard drive accesses just by seeing svchost.

One thing I would suspect off the top of my head is a Windows back-up process running to provide recovery service. If you installed XP off the IBM restore disks, you could also be seeing the Rescue and Recovery functionality (but I am not sure if that would run under svchost).

If you could follow the information and procedure in this Microsoft KB article and post the results of Tasklist /SVC and Tasklist /FI that involve the instances of svchost it may be easier to tell what's causing the disk accesses.

That is interesting. In your current setup, does Windows declare the system drive removeable or fixed?

xosh wrote:And turned off the page file (or virtual memory) option, indexing service.

You could turn off the "write last acsess time" NTFS-feature as well. Disabling "most recently used" writes is a good idea, too. I am not saying either of that is your problem.

Write cache for the drive is switched on?

I'm happy that you're as far as you got! How did you do the clean Windows XP Tablet install? I am about to start with an install. I have the X41 Tablet Rescue and Recovery disks, but I don't have a working hard drive to pull any files off of. My drive died for the second time and being fed up with the spinning platters, I'm opting for the CF route.

Thanks much!

First of all, thank you for you comments. After some investigations, I realized that the problem was in "wuauclt.exe" which is a part of Windows Update. Since I had a clean install (Windows XP Tablet SP2), I had to update the windows. So, I only installed the ethernet / wireless driver and then performed a windows update.

I'm not sure whether this caused a problem or not, but I chose to run the "Microsoft Update" instead of "Windows Update". After the first update (which includes Windows Installer 3.1, and some malicious software removing tools, and genuine advantage something, etc.) and a reboot, this problem started.

I was able to stop the hard read/writing problem by turning off the "Automatic Update" from the service. However, because of that now I cannot get the windows updated. I don't know why these Microsoft update causes so much pain .

Since I didn't any updates other than the first few, I'm thinking about manual update. I'll update it if I found a better way....

Did anyone have similar problem by performing a clean install? Or is it just happening to me? [I've re-installed Windows XP more than 100 times, but this was the first time I had problem with Windows Update... ]

I ran "diskpart" to check it.

Initially, I put the disk to a USB 2.5" HDD case with FAT32 format. At that time, the system recognized it as "removable device". However, after formatting the disk NTFS, (and installing it as the primary IDE disk of my X41t,) it is now recognized as "partition" - think it means "fixed device". [Please tell me it's wrong if I'm wrong.]

Then, I'm able to boot from the CF. However, I have to see "2010 Error" whenever I restart the machine. Does anyone know how to make the "2010 Error" go away from X41t? [I have the latest BIOS updates.]

And yes, thanks for your comments, I checked the "write cache" option. But it didn't help that much.

Are you seeing network activity while the hard drive is busy, or alternatively, does the problem not occur when you're not connected to a network? I think one of the settings for automatic updates are to download the updates in the background and then notify the user when they are done. I cannot remember if this is the default setting, though. On a clean install you'd have a lot of updates to download (and store on the hard drive). I don't know if this is the cause, but I can see it being one.

Running Windows/Microsoft Update (*) manually is not a bad solution for now. Maybe try getting your computer up to date with all the updates (heh), then re-enabling the service and see if it still messes with your drive?

(*) Microsoft Update is essentially the same as Windows Update except it also provides updates for some other Microsoft software if you have it installed. Office and Visual Studio are two programs I've seen updated.

That's normal for USB devices. It has nothing to do with the CF card.

So the Delkin cards are fixed disk. Good to know.

I don't think the problem is related to network since I cannot see any traffic during the HDD Read/Write. If it had some network traffic, I'd believe that it's downloading updates from the Windows Update server. But, since it was not... I'm not sure.

I mentioned Microsoft Update since I read an article from Microsoft forum. Someone was having a problem because wuauclt.exe was taking all the system memory resources (up to 40+MB!). People answered that it happened because of some "error" on the wuauclt.exe and can fix it by using "Windows Update" instead. Even though I cannot see any difference at my system, I think it's still worth mentioning it.

Well, it's Christmas... Merry Christmas to you all~

I believe there are lots of articles on extracting files from your HDD (which has Windows XP Tablet installed) to create a Windows XP Tablet install CD for clean install.

In your case, I think you would have to install the rescue & recover to any HDD, and then create the XP Tablet CD from that HDD. (Hope you have other machine to work on... ) I'm not sure whether you can rescue & recover the system on non-thinkpad machines, but I hope it'll work out for you.

Otherwise, you might be able to download the CD images somewhere in the internet or ask your friend how have X41t to create the CD for you. (I think the first will be illigal,

but that's another option.) This case you don't have to mess around with your rescue & recover.

Anyways, hope you solve your problem!

Actually, while the legality of downloading a copy of WinXP may be dubious, nobody will come after you if you've got a valid SKU, which should be on the bottom of your PC. If the SKU checks out, your copy of Windows should register with Microsoft as "genuine."

This is akin to the debate about downloading music albums you already bought in a store. If you've already bought the physical media, do you not have the rights to the digital forms as well? Supposing you have no viable means of getting that media on your computer..how is it sensible to punish a listener for downloading to his hard drive an album he already owns when he would not be punished for ripping it from a CD?

I won't claim to be a lawyer, and I doubt if my arguments would hold water in a court of law, but there are too many Windows pirates who never paid for a license in the first place whom nobody goes after, so it's not like you'd get nabbed for it. I'm just trying to make you feel better about software piracy.

xosh, i think it's important we get some data on the running flash card first. please check if the card is running in udma, and which mode. Also, check transfer speeds with a tool like hdtach. Make sure the blocksize is set to 1024K in hdtach. Also, make sure no other programs are running during the tests.

Once we establish which cards work well with our x4x series we can leave the experimental stage and make this a proven solution. This makes it easier for alle X4x users to determine if going solid state is worthwhile.

So, know I'm running Thinkpad System Update to install the important driver and utilities. I'll post the benchmark result once everything is settled.

Ripping a CD on a computer is an "unauthorized copy"!
Came on the news last week. This is an official statement from the general lawyer of SONY BMG in the latest RIAA case.
According to the RIAA you should buy another electronic copy.

These are official statements, when you google after it.

Hi all, I finally am going to post my HD Tune result on 16GB Delkin UDMA CF card (with Addonics CF-to-IDE) on my X41 Tablet.

The result wasn't as expected, and I believe there's more things that I could still do to improve it (otherwise Delkin has been bragging about their product...).

First, the drive was detected as UDMA-4 (not 6).

HD Tune result:

1) Original Hitachi 60GB HDD

Transfer rate
Min : 4.0 MB/s
Max : 22.4 MB/s
Avg : 17.8 MB/s

Access Time : 22.8 ms
Burst Rate : 71.0 MB/s
CPU Usage : 2.9 %

2) 16GB Delkin UDMA CF

Transfer rate
Min : 1.5 MB/s
Max : 31.6 MB/s
Avg : 30.3 MB/s

Access Time : 0.4 ms
Burst Rate : 29.8 MB/s
CPU Usage : 2.5 %

I did all the first 5 steps that "Lewster215" (on Page 5) suggested. I tried step 6 (which forces UDMA-6), but I only got UDMA-4. However, as far as I know UDMA-4 supports up to 66 MB/s, and hence, it'll not be the bottle neck. (But, I would appreciate if other CF card users could post their UDMA settings.)

Anyway, Delkin says it has transfer rate up to 45 MB/s and "Tekkaman_Slade" posted (also on Page 5) much better transfer rates with 8GB Lexar 300x cards (almost 40 MB/s).

Please post me any suggestions to improve the card speed. I'm still trying to find out.... Thanks.

If the card itself cannot exceed UDMA4 then it never will, no matter what you try.
Some UDMA CF-cards (Lexar, Kingston) are supposed to support UDMA5. Most stop at UDMA4. With current transfer rates UDMA4 is sufficient.

Up to...

That is not surprising. With current controller technology speed is limited by the density of flash cells. Double capacity in identical volume has to affect speed.
