External hard drive and ExpressCache

Yes just reformat and give it a new volume. I did this to mine and just switch my page file to it for now or just use as a second drive. Had to many problem with the ready cache software for now.

Thanks Chas488,

Yes, I too am frustrated with the ExpressCache software. Also disappointed in the lack of response from SanDisk.

If you don’t mind offering me some assistance. If I go to Disk Management and select the ReadyCache SSD disk, the format option is greyed out. Do I have to delete the volume first, then format, then…? Thanks in advance. 

Did you uninstall the ready cache software? Delete  the drives partition,formatt and make new volume

from what i understand the expresscache software should ignore any external drive marked as removable. Are your External HDD marked as removable disks or fixed disks when you look at them in windows explorer?

Chas488, thanks for your help. Looks like I just need to delete the volume first. I think I will just use this for my photoshop scratch drive and maybe try again next time ExpressCache gets updated.

drlucky,

they show up as Local Disk, not removable storage. I was under the impression that External USB Harddrives always showed up as local drives, but only things like flash drives showed up as removable. These are just WD 1tb external USB drives.

@Centurion,

I am not using the ReadyCache product…

However, I’m using a Maxtor External USB drive which is formatted as NTFS.

It shows up as a Local Disk.

FYI.

Well ExpressCache 1.3.0 has been installed and the same issue still happens when removing the ‘removable USB device’ external hard drive (WD 1023). Checked USB HD for system/ surface errors and viruses using AVG and nothing.

Anyone else still encountering this problem?

Hm, I will try the external drive later when I get mine back:P

So far usb flash drives don’t have issues…but they shouldn’t defrag regardless.

Taking defrag control away should have come with some options to exclude…I"d like to exclude my media drives for instance, no reason to defrag those all the time.

ExpressCache version 1.3.0 DOES NOT cache or defrag any USB drives regardless if they are are defined as Removable or Fixed. It will only cache and defrag SATA drives.

Update: After uninstalling USB device and restarting the PC, I attached the external H/Drive and windows installed the device.

After this procedure I can now remove the USB device with Expresscache running. :smileyvery-happy:

The previous errors in removing USB device have now disappeared which must have been corrupt USB driver files and from the results, not the ExpressCache software. All running well!

Here is a link to the utility which can remove USB devices on the fly for re-installation if anyone else is stuck with this:

This not true is my system. I’ve just plugged a phone configured as mass storage via USB to copy some files (that I presume that were also cached), and the Safely Remove’ icon under the taskbar refused to remove it, saying that the device was in use by a program. After killing ExpressCache.exe via taskmanager, it could be instantly removed without any error.

I’ve faced the same behaviour too with a regular flash pen drive under 1.3.0.

No gls,

I have the same issue, but only with this new version 1.3.0. In 1.2 it goes well!

Regardless on the type of USB pendisk I use, it always deny to remove it.

Caching looks fine; are you sure this did not happen with 1.2.1? Also if you exit the ExpressCache gui app and kill the expresscache.exe service in the task manager does itstill state you cannot eject the pen drive?

Thanks!

If I kill expresscache.exe I’m able to extract the pendrive safely. Till then it flashes again and again like there were activities, even if I have no files open.

If you cannot solve the problem, I will uninstall 1.3 and reinstall 1.2.1: it had not this problem.

regards,

No solutions?

I don’t think it’s a minor problem!

Just an update. I stopped ExpressCache in Task manager for several weeks, and all of my external hard drives worked correctly and I could eject them. A few days ago I turned ExpressCache back on, and again ExpresCache is constantly accessing the external drives, I cannot eject them. Although everything seems to work ok, the constant drive activity is a concern.

Some have said that ExpressCache does not defrag or cache USB drives. This may be true, but it is certainly doing something with the drives.

Obviously I am not the only person with this problem. It is unfortunate that someone from SanDisk cannot shed some light on this problem.

I’ve finally uninstalled 1.3 and reinstalled 1.2.1.

now IT ALL WORKS FINE.

I saw this issue once after upgrading. I rebooted the PC and after that Safely remove hardware is working noramlly for me.

Absolutely not the same for me
